I've seen this problem described elsewhere, but haven't been able to identify any sort of solution. Forgive me if I've overlooked something obvious.
I have an Epic 4G that I rooted with CW quite some time ago. I flashed a few various ROMS before settling on Midnight ROM 5.2 (EC05), which the developer says is based on the Bonsai ROM. My SD card at the time was the stock Class 2 Samsung. I use an app called "Move2SD Enabler," which sets the default installation path to the SD card whenever possible, and a second app called "App2SD Pro" that helped me easily keep track of where things ended up, and prevented me from accidentally installing widgets to the card.
One evening, I played around in the Market and downloaded several various and assorted apps - significantly more than I would usually download. None were likely to affect the actual system in anyway (mostly games and utilities - that sort of thing). A few days later the phone locked up and I pulled the battery. When it restarted, none of the SD card apps were available in the app drawer, and any shortcuts on my home screens were replaced with generic icons that displayed "could not launch the requested activity" when tapped.
All the contents of the SD card were viewable within My Files and when connected to the PC by USB cable or by inserting the card. I tried several things, including running a chkdsk on the card while it was in the PC, but was never able to recover the use of the apps.
Eventually, I replaced the card with a new Class 10 and reflashed, upgrading to Midnight 5.5 BYOR (also Bonsai based). I installed many, many apps (approaching, if not exceeding 100 installed to the card). Within a few day, I rebooted the phone only to have the same problem repeat itself. No crash this time - just no SD apps after a phone reboot.
So I tried it again. This time I ODIN'd back to stock, then rooted with Bonsai Masterkey (as per the developer's recommendation) and flashed the ROM again. And again, within days, I lost access to the applications on the card. The files are all there, but it's as if Android can't enumerate them.
So... again I ODIN's back to stock and rooted with Masterkey. This time I flashed Bonsai 4.1.3. I spent a few days installing apps (rebooting now and again as a test). The number of apps installed to the SD card was 127. The phone froze up, and I pulled the battery. And...
Once again, all the apps are gone. They're there on the card, but not on display in the app drawer.
So... three ROMS, two SD cards, journaling on, journaling off, sometimes after a crash, sometimes after a reboot - all SD based apps simply disappear.
What gives? Is this a known issue with Bonsai-based ROMS? Does the Android O/S limit the number of apps that can be stored on the card? Some mysterious issue with EXT4? With the EC05 kernal?
Is there some way to force the OS to re-examine the SD card? Some way of restoring the missing links?
One last note, in case it may be of use. While the first problem occured with whatever the default partition is on the SD card, the subsequent installs were done after manually partitioning the card using either CW or Masterkey. I set the ext partition to 4096MB, and set the swap size to 256MB. Is that in any way relevant to my problem?
Thanks, in advance, for your input.
I was doing some additional research on the mysterious disappearing app syndrome, when I stumbled across a couple of different articles in which it was stated that Android Froyo has an installation limitation of 123 apps on an SD card.
One (http://androidforums.com/evo-4g-all...d-app-limited-123-but-im-running-2-3-3-a.html) even shows a screenshot of Titanium Backup complaining about the issue (the actual article is unrelated to my problem, but...)
Another (http://www.androidtablets.net/forum/samsung-galaxy-tab/11230-app-limit.html) shows a reply down the page indicating that "There is a limit of 123 apps that can be moved onto SD Card, found that out the other day...... something about the limitations of Froyo"
Neither of these (nor the other articles I found) were from anything close to an "official" source. So, I'm asking: Is it true? Is there a limitation to the number of apps that can be installed on an SD card in Froyo? If so, that might explain my trouble when my own installations reach beyond the 123 app limit.
And my followup question: If it IS true, do the limitations still exist in Gingerbread?
For what it's worth...
Having reduced the number of apps on the SD card to 120 (less than the alleged limit of 123 apps mentioned above) appears to have completely eliminated my problem. No more disappearing apps (knock on wood).
I would still very much like to know, officially, if there really is such a limitation, and whether the limitation exists in Gingerbread as well. But for now, I thought I'd post my apparent success, on the off chance that it might help someone else struggling with the same problem.
Thank you.

Hi!
I tried searching the forums for the problem but couldnt find anything related to mine!
I have a problem where the phone suddenly just says "No write access to file" when i try listening to stuff on spotify, take pictures etc... Yet i can access the SD on ASTRO.
Has anyone else noticed this one? Any tips? Rebooting the phone fixes the issue for a while.
Same issue here. I found in other android related forums a lot of people complaining about this as well - seams there's no solution yet (reboot helps in my case - format the card didn't). Some people reported that a change of the sdcard hasn't solved anything. I guess we have to replace the device.

Don't give up yet, if you are running a task killer, remove it and try without it.
As I said on the other thread, I removed it and I'm now testing it. Atleast now it seems to sync Spotify's offline playlists without errors..

I have no task killer running but still the above mentioned issue. I also removed the sd-card and put it back in several times. I cleaned carefully the contacts of the sdcard, removed ALL apps but it still happens every other day.
And no, the desire wasn't plugged into the pc via USB. m(
i had the similar kind of issue. when I switch on the phone from standby mode.. sometimes it says "cannot backup the phone data.. SD card not accessble". When I opened the Estronge File manager I can see no files under the SDcard..
This problem has started to me only after I have installed ebuddy and started using it. Then I have uninstalled the ebuddy and till now i did not get this problem again (3days tested after uninstall)
You can give a try by uninstall any recently installed apps.. my doubt is some apps are creating this issue on slow writting SD cards (my Sd card is Class 2)..

Been there, done that! *sigh* It happens also with no apps installed (plain stock)
Also just happened to me after installing a Touchdown update - camera was reporting no access to SD card and Astro (file navigator) was showing some weird behaviour (opening the 'download' folder took me back to the home screen)
A reboot appears to have solved it but a bit worrying
Not sure if this is 100% related, but I'll include it here. This didn't happen to me at the start but has started happening in the last few days.
I've had my phone set up to connect by default as a disk drive without asking me. Now when I connect to my computer, I get the message on my computer that there is something wrong with the drive and it needs to be scanned and corrected. I don't because I don't always trust Windows auto corrective measures, you can't always go back.
The problem really kicks in when I connect my Desire to the computer and it (the computer) says card needs to be formatted. As soon as I get this message, I know it's all over. I can't access the SD card on computer or from the phone. When I disconnect, the phone says the SD card is empty, and I get the small SD card with question mark up in the top right of the notification bar.
My system is running Win 7 x64.
I get the same problem every other day with the "cannot backup the phone data.. SD card not accessble". I also got an error message when trying to download an email attachment saying that there was no storage space but Astro shows around 6gb free on the sd!

you have another sdcard than the stock SanDisk 4GB card, I guess? If so, could you tell us what sdcard you are running?
I have had the same problem as reported above (backup error) recently. A reboot solves it, but not permantely.. (I also had a problem where the home screen froze, but the lockscreen worked fine. I guess it could be related but I don't know...)
It's a bit annoying with these kind of problems..

It just happen again after I replayed to a text messages..
I started my terminal emulator and checked if the sd card was still mounted (which it appeared to be). But noticed that it's set to remount as read only on errors (Not saying it's the problem, just that it may be the cause of the symptoms..)
Then I checked the rights (ls -l -d /sdcard) It was set to ---rwxr-x (owner: system, group: sdcard_rw) = Owner has no rights, group has full right and others read & execute only..
Also one thing I noticed was that the date was set to 1970-01-01 01:00 (aka start of "unix-time"). That can happen, but it still seemed a bit strange..
BUT: Apparently, that is the way it's "supposed to be", as after a reboot it says the same..
This was just an update on my experience with this error, and what I've tried (so far)..
Stock Rom and card and it is happening to me periodically.

Update: A working solution?
I read on another forum where they (Vodaphone actually) recommended that you reformat the card if you have this sort of problems... So I thought: What a heck.. It can't become worse..
These is the steps that I did (pretty straightforward..) and it works (for about two days now without any big problems..)
Backup the card
You probably don't want to do that using Windows... (You can download free Linux Live-CDs from Ubuntu.com or other places)
Why?? For me, and I don't doubt you may encounter something similar, Windows wanted to reformat the SD Card before it mounted it (DON'T do that if you want to backup your files [and I'm not sure on what the phone would think about that]).
I guess it could work Fine in Mac OS X (but I haven't tested..)
Reboot the phone (mine had trouble recognizing the card after I had disconnected it from the computer)
Go to Settings > SD and phone memory (* ) >Unmount SD Card > Format SD card
Reboot again (not shure if it's needed but just to be sure)
Connect to the computer and put your data back on (be careful, the best is perhaps to only transfer "your stuff" and not replace any files that already are on the card). AND BEFORE you pull out the cable, make sure you unmount the card from your computer!!!!
Done!
(* Translated from Swedish, don't know what it says exactly in English.. )
If you need directions for how to use Linux for this, feel free to contact me..
Try doing a google search for h2testw its a bit of software that can be downloaded that test SD cards and removable drives. I recently had a problem with a new card ran that and it told me that the card had a problem, I sent it back and got a new card and don't have any problems now although they were different to what you were experiencing.
I get the same issue about once enery couple of days. I'm first alerted to it when I get a notification saying the automatic backup has failed, then no writes are allowed to the SD card. It's solved temporarily by rebooting.
Phone is stock, Orange ROM, stock 4Gb card. I use HTC sync and often use the phone in disk drive mode.
Simple damaged SD card...
Sent from my HTC Desire using the XDA mobile application powered by Tapatalk
All my issues disappeared after i removed the task killer.
Just today, I've started getting issues. It *only* happens when I try to open Spotify. It was working fine this morning on my way to work, but now every time I open the app, the SD card gets mounted as read only. I have used Quick App Clean Cache, and wiped the cache within Spotify itself. Rebooted, powered off, removed and reinserted SD card, and nothing fixes it. ****ing annoyed and pissed off that this keeps happening.
So, the specs are following:
Rooted Desire
Official HTC Froyo ROM v1.0c by AdamG (with latest radio)
EXT3 partition with enabled A2SD (not Froyo's)
Sandisk 8GB class 6 card
Yesterday I've created EXT3 partition on my SD card, reinstalled fresh ROM (did all wipes before), set up all programs (A2SD enabled) etc. Everything was working like a charm until this morning.
Just for the record, this ROM worked excellent even without EXT3 partition. I was using Froyo's A2SD for a week. Yesterday I've decided to set up the unofficial A2SD in order to free some internal memory.
Symptoms:
- File explorer is hanging when it's trying to access to SD card. Some times the screen is black and FC popup jumps, some times after a minute it opens SD content. But scrolling and browsing the content is pain in the a$$ and it results with "application not responding" popup.
- Market cannot download new apps. Actually download starts, the icon in status bar shows for a second and then dissapears. There is a progress bar under the "download" section but it's stuck. Few times the Market has crashed too. Tried over wifi and data connection - same result.
- Selecting ringtone from SD card is slow or impossible. Default tones are played instantly and SD card's are some times played after minute or two, and some times results with "application not responding" popup. I can receive calls and messages but they are muted.
- Camera can't take a picture or focus. Can't open camera settings... Gallery is also slow. Browser also get freeze after opening a home page.
I can't remember I did anything crucial this morning. Everything worked fine yesterday. This morning I've sent few emails, browsed the internet a little bit, nimbuzz, listened to some music, connected mobile to the computer and exchanged some photos... Nothing installed, nothing modded.
Tried reboot several times.
Tried killing problematic apps and open them again.
Tried reboot without SD card - stuck on green htc boot screen
Help?
It seems some folders on fat32 partition was damaged or corrupted. However, I formated card in windows to prevent formating ext3 partition, and now everything's running smoothly.
Does anyone know why this happend? Two folders were corrupted: one is created this morning (it's new), and one is backup folder for one app (it was automaticaly created yesterday).
Seen similar behaviour. Can be caused by disconnecting the phone from the pc when it's still executing write actions. Probably there can be more causes but this way you can even reproduce it.
I had this with one card and it became worse over time, regardless of formatting. Easiest thing to do was to remove the damaged files/folders via cmd instead of via explorer. This saved me recopying everything on there again like after a format. In the end i replaced the SD card as i couldnt get it permanently fixed, just as if a couple of memory cells had been permanently damaged and the card would start to act weird whenever something was written to those cells.
So, just keep an eye on your card and you should be fine
for some time I was using a Samsung 8GB SDHC Class 2 which came with the device.
I have made it a Goldcard, rooted the phone and installed Froyo. then I began to get SD Card Unexpectedly Removed errors after a few minutes of using an app instaled on SD (mostly when I tried to run ColorDict, which keeps dict data on SD). I am not sure, but I think this began to happen when I tried to upgrade to OTA 2.29 and "Red Triangle of Death" (lol) appeared... my Desire was getting unusable as it happened more frequently and required the phone to be powered off and the card to be taken out and insterted again. I tried formatting from Windows level, from phone level, checking for errors, bad sectors etc, but everything failed, so I bought Kingston 16GB SDHC Class 4. and, as you can expect, nothing really improved. well, maybe the errors were a little less frequent.
so I tried to change the ROM, yesterday I have flashed LeeDroid 2.3d No-A2SD, since then the error came twice - first when I tried to wipe sdext in recovery and about five minutes ago, while accessing the card with Root Explorer. I have to stress out that I use the SD intensively through the day as I install apps and test new games. so it seems that the appearence of that error is somehow related to ROM as normally it would happen much more frequently.
did anyone experience similar coincidence?
I have had the SD Card unmount itself randomly before with a custom ROM but it has been a one off. I just rebooted and it was working.
However, your problem is quite extensive. I guess you could just sort of leave it for a whole day not doing anything and see if anything happens. If so, then it could be a number of reasons. Reformat, check for errors (thoroughly), change your ROM to stock and test that out.
Hello everyone,
I just recently purchased a Samsung Galaxy Tab Pro 8.4. So far I really like it but I am having a problem. I have a 32 gig sd card plugged in and yesterday I tried putting some files on. Nothing fancy just music, a video, a couple kindle books, and some word documents. I had plugged the sd card into my computer dropped them on and put it back into my device. Well the device wouldn't find or acknowledge any of the files at all. It acted like they just didn't exist. So I plugged the sd card back into my computer and they were there. After a bit of rebooting my device I finally got it to acknowledge the stuff I put on. That lasted until I let the device go to sleep. This morning when I opened up my device everything was gone again. So I plugged it back into my computer and it was all actually deleted.
After that I tried putt stuff on it with the device tethered to my computer and the same thing happened. It wouldn't acknowledge anything kept on my sd card. Including kindle books.
I did some reading and just kept coming up with the kitkat and app compatibility issue that doesn't allow apps to save to sd but this doesn't seem like that. All of those posts seemed to be dated a few months ago so has that been fixed at all or is it still a problem and the only "fix" is rooting it? Is it related to the problem I seem to be having? If not what on earth is worng with it and how do I fix it?
I won't lie I am kind of a newb when it comes to anything beyond basic electronic issues so I really am at a loss for what is wrong with it.
Thank you in advance for any help.

P.s. Should I consider returning this tablet? The stuff I read about the kitkat seems like a huge problem when it has such a small amount of on board space. I have just basic stuff on it and still only have 6 gig on board left over. That means basically all storage will be on an sd card. I bought it to use for college so want to be able to take notes and reliably save stuff. Am I better off with a different tablet? If so what Android tablets would be best?

Any rooted tab is better.. Rooting it will allow you to fix your SD permission woes. More than likely the app you are using can't get access to the SD card thus why it shows up blank. Root the tab, and run the kitkat SD card fix app and never look back. This tab is great!

So basically it will always have the sd card issues thanks to kitkat? I tried opening the music and the video with the devices main video and music apps. But they also weren't showing at all when I went to look for them in the actual "My Files" section. Then when they totally deleted I got even more confused. It was 5 gigs of stuff just randomly deleted off the flash drive.
Is rooting hard? As mentioned I am a newb. I have never done anything like that and I have never used or worked with a rooted device. Won't it void the warranty and make it so I cant return it? It was fairly expensive so I am worried about ruining it haha.
I actually love the tablet so far so really disappointed with the issue. I have until the 14th of August to return it so I need to decide quickly.

Hi
I'm not new in flashing ROMs but I think somewhere I go wrong...
I had the Australian stock ROM and I thought to try a little bit de-bloated ROM to check if its better...
As I'm ALWAYS doing I did make a recovery full backup of my tablet and copied the TWRP Backup in my Ext. SDCard with the intention to move it in my PC for security. Reading how to flash the new ROMs, couple of times have been mentioned that I have to wipe EVERYTHING before I flash them... Against my better judgment I wiped my SDCard too and of course I wiped the new ROM too...
Oh well I thought I will restore my Backup and try again
1) TWRP did NOT read the backup from Ext. SDCard.
2) I d/l an Aussie ROM from SAMIFILES to start again and copy the TWRP Backup in SDCard in case something wrong etc...
Then All Hell Break loose
After Flashing the Full factory ROM I had in my tablet few only apps without ANY Google apps and I couldn't access my Ext SDCard...
When I took out the card to copy it in my PC and from there to tablet the card was corrupted loosing my original Backup...
After that I don't know how many times I've tried factory or XDA ROMs with all the time not able to access my Ext. SDCard (New one, works fine elsewhere) despite I tried ALL the SDFix apps in Playstore... I tried to change the properties of the card manually too but the same...
PLEASE can help me to Fix my Ext SDCard as the tablet is almost useless without it?...
have you tried copying the files to your main memory, then transfer those files from main memory to your memory card using the built in File Manager ?

There is a lot of misinformation and misunderstanding about the SD card permission changes brought by KitKat, and I do not believe the OP's issues are caused by those changes. We are unfortunately to the point where if someone has any trouble at all with an SD, they blame the KitKat permission changes; which is simply false in many cases. The KitKat SD changes have to do solely with write permission access and do not affect the ability to read the SD. The following article explains it well:
http://www.androidcentral.com/kitkat-sdcard-changes
And the KitKat changes certainly would not cause the card to be read after a reboot, then randomly not readable later, as the OP described. All this is pointing toward an issue other than how KitKat handles SDs.
I would suggest re-formatting the SD to FAT32 (on that subject, what is it presently formatted to?) and seeing if that helps. I saw a very similar thread on the HTC One (M8) forum where the person was having trouble with the phone reading content on the SD (worked fine on other devices), was blaming the KitKat rule changes, and simply formatting the card fixed it right up. Also, try a different SD card, if you have access to one.
If that doesn't work, its possible where is some software or (hopefully not) hardware issue such as a broken SD tray. But let's try to format the card and see if that does the trick.

Sorry if I didn't make myself clear... I CAN see the Ext.SD but I can NOT write... The card (2nd) it's empty and I can write in it files in my PC's Card reader which I can see in my tablet... I CAN NOT write a file or make a folder or anything when the card it is inside the tablet...
That's why I said the tablet it is almost useless as I can use only the native 16GB minus...
EDIT:
Problem SOLVED for whoever need to know how go here: http://winaero.com/blog/unlock-external-sd-card-writing-for-all-apps-in-android-4-4-kitkat/
Thank you guys for the help so far. Sorry I am a bit slow but my laptop died on me and I have been dealing with that.
I am glad to hear its more than likely just an sd card problem not the kitkat problem. I really don't want to root it. I actually adore this device and don't want to had to return it.
I have played with it more and I am getting stuff like pictures and videos taken on the device to save to sd so it is reading the sd card. It just wont read what is placed on it externally. Is is maybe that I have to tether and cant pull the sd card out?
I did reformat the sd card with the device. So it is formatted to the device. But it still wont acknowledge stuff I drop on it only stuff that is saved on it from the device itself. But I do know its working because its showing pictures I have taken with the device on the sd card in the built in file manager. So whatever it is it's not the card reader slot.
I am going to try xdm9mm's suggestion and see if that will work. If not what else should I try?
Before I can test another sd card I need to buy one (I looked and only had the one extra lying around). So what card do you guys use on it with success?
You're taking the card out and using a card reader? I think I know your problem, the same thing happened to me when swapping cards with my phone. You have to go into the system settings, and under general, select storage. From there you can unmount the microSD card before taking it out. If you don't do that, it won't read the card properly when you put it back in.

Every time I have taken it out I have used the unmount section. Originally I unmounted it put it in the adapter and plugged it into my computer. Then I dragged and dropped everything I wanted on it to it. Once I had done that I used "safely remove" on the computer and then plugged it back into the card reader on my tablet. That is when it wouldn't read anything at all. I reset it several times and finally got it to read for a minute but then when the tablet went to sleep it self deleted everything on the card. I am thinking the self deleting may be fluke because I have been able to save pictures taken by the device on it with no trouble. It just won't read anything I put on myself.
The whole thing is a bit confusing lol. I even took it to a computer shop in town but the guy had no clue what I was trying to explain. I am going to try another sd card and try tethering the device to the computer to drop in some new files. Hopefully that will help.

Then I dragged and dropped everything I wanted on it to it. Once I had done that I used "safely remove" on the computer and then plugged it back into the card reader on my tablet. That is when it wouldn't read anything at all. I reset it several times and finally got it to read for a minute but then when the tablet went to sleep it self deleted everything on the card. I am thinking the self deleting may be fluke because I have been able to save pictures taken by the device on it with no trouble. It just won't read anything I put on myself.
The whole thing is a bit confusing lol. I even took it to a computer shop in town but the guy had no clue what I was trying to explain. I am going to try another sd card and try tethering the device to the computer to drop in some new files. Hopefully that will help.

Hrm. Another possibility, have you tried filling up the card, say with video files, then checking from the PC to see if they all play? Most of the really cheap memory cards are fake (including on Amazon), they only have a tiny capacity, and the controller is set up to loop, so it will write the data without giving any errors, and the files will be indexed, but the data isn't actually saved anywhere.
Hi,
I've updated to CM 12 Nightly ROMs (currently 12-20150216-NIGHTLY-a5), with a clean install, to get away from the restrictions on SD cards in 4.4.4.
Although I do seem to have SOME access to my card at seemingly random times, I mostly do not. I've seen nightlys which stated they've fixed SD card issues and have updated to them, and for the past couple of weeks, I've been updating multiple times a week. But at present, I cannot even move what seems to be less that 2MB in most cases to the SD card, even with a root-enabled file manager (Yes I am rooted). Do I still have to edit user rights for my owner account?
I've gone into my app preferences and chose the SD card as my preferred install location as well, but it seems that this option will only install to the emulated/sdcard0 directory. I get the same result if I use the app manager and choose "Move to SD Card".
I constantly have to purge info from my internal memory just to even be able to update apps. I have about 54GB free on my SD card according to my phone. the 10 or so gigabytes used are from a manual backup that I had performed before flashing, using my PC only.
Could anyone please help me with this?
Please? Anyone?
Hmm,
Seems most of my issue was fixed just by using ES File Manager instead of CM File Manager. I still don't have much space at all to do anything special, nor can I install Apps onto my real SD Card...
