No write access to SD

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...

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.

[Q] HELP! Desire won't boot up, Clockwork mod recovery accessible

This is my first post on this forum (figures I'll jump head in when I have a serious issue,ha?)
Ok here goes:
My Issue: HTC Desire is stuck on boot-up screen with Green HTC logo forever.
How it happened: I tried flashing a script using ROM Manager that was supposed to correct some local language settings, over my current rom.
Phone state before action: Worked beautifully using Modaco R8 RC1 ROM. Phone is of course rooted.
Why I can't solve it myself: Well, this is my first serious issue (well, I hope it's not serious, actually!) with phone, which i've had for about a week , so I'm relatively a n00b.
-- I can access Clockworkmod recovery. However, under NANDROID RESTORE there are no files. I have no idea why, because I DID a full nandroid backup before that install. I have a copy of all the IMG files of the last working setup on my windows machine hard drive, and my assumption is that maybe I accidentally moved the files to the hard drive after i did that backup, instead of copying them.
Now -
1) Can I somehow restore the phone to a working state without the nandroid backup, using some other function of the CW Mod recovery?
2) Can I somehow connect the phone via USB to the computer and get it to read the Micro SD card so I could maybe move the IMG files I have back to SD Card (using a mounting option)?
3) Anything else I could try?
If nothing else, please just calm me down if you can and let me know the phone is fixable and not bricked because I can access recovery?! That would at least help me go through the night...
last note: Before I flashed the zip, ROM Manager said my CW Mod version is 2.0.5.7. Within the recovery itself, it says the version is only 2.0.5.1. Don't know why that is , and if it is important.

You could read the SD Card directly with your computer. If you don't already have a microSD/USB reader, they are very cheap and will prove very useful in situations exactly like this one.

You are right! Indeed they are very cheap, but, unfortunately it's going to be a game of patience for me, because it's late evening right now and the shops are closed.
That's why I Was wondering if there's an option to mount SD using HBOOT or Recovery so I could end this ordeal tonight...
Anyway, The fact I could get into CM Recovery means the phone was not permanently damaged, right?

Right, if you can boot into recovery it's a good sign.
I have an N1, not a Desire, but in my CM recovery menu under "partitions menu" there is a "mount USB storage" option. Try that?
Alternately if you own any other phone with a microSD slot that can mount it via USB, it could be your makeshift USB reader.

I have had a similar issue before! What I actually ended up doing was pushing the files using ADB. Its quite easy and I'm sure you can find lots of threads on how to use it. Once the files are pushed to your SD card you can then restore it

FIXED!

Problem solved! And yeah, that's how I ended up doing it.. no micro SD card reader was needed..
I installed HTC Sync for the device drivers... then connected the Desire with the USB cable .. and worked out of the problem using ADB commands..
luckily, the guy whose update I installed that caused the problem has the same ROM as myself, so I installed his framework.jar file , and the machine is fine yet again!

[Q] CyanogenMod 7 is ruining my SD cards

Now I'm not moaning about CyanogenMod here, I'm just trying to understand how I can fix the issue.
Basically, I had CyanogenMod 7 RC2 on my Desire Z. That was it.
Eventually I saw through ROM Manager that the full release of 7 was out so I downloaded, took a backup, wiped everything and did a fresh install of the new ROM.
It installed fine, but none of my apps that needed root access were getting it.
So I booted into recovery, restored my backup, root was back.
I then installed 7.0 over my RC2. That worked fine, but again root was gone.
At this point, my phone started damaging SD cards.
It suddenly started saying that my 8GB card that came with the phone was damaged. I tried to fix it on the phone, but it just said 'Checking card' and then giving up.
Putting it in an old MP3 player, it is not detected at all.
Putting it in a card reader, the card is unreadable and when I try to format it Windows says the card is 'read only' (this is not due to the reader).
I put a functional 2gb card I had lying around into my Desire Z and it broke it in the exact same way.
My question to you guys is - what could be causing this and how do I fix it because I have a 16gb card coming and I'm obviously cautious of putting it in the phone.
Also, how would I go about flashing the new Cyanogenmod 7.02 ROM if my phone keeps breaking SD cards I put into it?

This error can be because when ever you install a CyanogenMod ROM over another, It leaves files your new ROM think is useful such as data that the new ROM doesn't support. It is damaging your SD Card because it keeps attempting to fix the error but is making it worst by trying to remove system files. Your best bet is to try another ROM and see if it does the same thing and report it to CyanogenMod Developer Team if it only does this to CyanogenMod ROMs otherwise it would be just a virus on your SD Card feeding off of personal data. If it is only CyanogenMod ROMs, we will adress this issue ASAP. Hope I helped

Thank you VS4, you are indeed helpful
I've since heard some people have managed to fix their SD cards by formatting them in ClockworkMod but I can't even mount it first in order to do this! Is my card truly dead?
Also, do you think the reason that CM7.0 had no root (even when it was a clean install) was due to me not 'fixing permissions'?
Thanks

Just a note to say that I've managed to fix it!
Despite being unable to 'mount sdcard' in clockworkmod, I found I was able to activate USB Storage and through this I was able to format the card (Windows 7 was previously saying that the same card was 'read only' in a multitude of card readers).
I hope this helps any poor chap with the same problem.

I had this exact same problem, munched 2 of my 8GB cards, and had a 16 on the way. I somehow fixed it before the 16 came and I've never had the issue since, glad to see an explanation of it.

Thanks, nofixio!
I had the same problem on my Samsung Fascinate with CM7. It ate my 16GB SD card to the point where the phone wouldn't recognize it, CWM wouldn't mount it, and it wouldn't show up on my computer in multiple SD readers.
I wasn't quite clear what you were suggesting when you said you were able to "activate USB Storage." I thought maybe you meant within CWM. That didn't work for me, but I was able to boot the phone up with the problem SD card in it and turn on USB storage as normal. Suddenly my computer could not only see the SD card, it could see all the files that were on it before it died! I backed everything up, formatted the card in Windows, and everything's good now. Thanks for the tip!

im running cm7 ... it wont read from computer. i tried several micro sd card readers. it just tells me it cant format. its just like what was mentioned before.

Weird, I've never had any problems with Cyanogen 7 roms. I've flashed one over another and had no issues at all, Mayb because I use SuperWipe before hand? Or maybe its a certain sd card issue???

Running Desire Z and Andromadus Beta 11 I had similar problem after I had applied remote wipe from Exchange (wanted to see if it works). Remote wipe worked: it destroyed contents of SD card and erased phone back to factory settings. After wipe mounting SD card failed and Andromadus seemed to be unable to format the card.
Solution: Booted phone to Clockwork recovery and applied advanced -> Partition SD Card.
Posted this on this thread since it came first when searching solution.

Go into Recovery (Clockwork), go to mounts and storage, then scroll down and it should say mount USB storage.

[Q] SD Card Issues?

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.

Some people on this forum have reported that towelroot works on Tab Pro 8.4. It should be as easy as installing an apk and tapping a button. I already have CM11 installed so I didn't try it though..

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.

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.

SD Card issues in Android 6

So I have a Samsung SD card and was immediately prompted to advise it was corrupt when I first flashed a CM/AOSP ROM. When I got the time to do so I backed up the contents, formatted from the prompt and copied stuff back over.
The problem now... The SD card cannot be written to by Titanium Backup. Edit the permissions platform.xml file you say? Nope didn't work. Nothing suggested worked.
I finally got it working by formatting everything, installing a Sense ROM and then formatting again once it said it prompted to. I can write to "SD Card 2".
However, I'm weary going back to AOSP/CW that I'll be back to square one again.
Has anyone encountered the same issues and what did you do?

Sort of. Every time I flash an aosp ROM it tells me the card is corrupt even if I'm just trying to use u it as portable/external. I backed everything up to my Mac book and formatted the card in the phone on CM13 but, when trying to transfer stuff back I lost my nandroids and a couple RUU.zip files. It still tells me the card is corrupted even though I did format it. I don't remember if I had write issues after that. At this point I have just about given up on aosp since I'm not going to copy and then format the card every time.

Same issue.
Does anyone have a solution for this ?

The SD shows up as corrupt, or Titanium can't write to it?
What did you try to do, and what were the results?
Posting "same issue" without giving any details is never a good way to post. More detail is always better.

Hi,
did you try this fix for TB?

No , I just get a notification that sd card is corrupt. There is option of setting it up too but in there when I select "use as portable storage , it asks me to format it ".
In any of the apps , sdcard doesn't show up or even option show sdcard.

I don't use AOSP ROMs on the M8, but I do on my Samsung Tab Pro 8.4. On that device, I get this error message (SD card corrupt) every time I flash an AOSP ROM. One thing that you can try which often works for me (but not always) is to put the card into a USB card reader, connect to PC. It should automatically detect the card, and give you a popup window asking you to scan and fix the problems. It has 2 choices with check boxes (forget what they say exactly) of which the first is checked by default, the 2nd is not (and takes a lot more time). Try the first choice, which should just take a couple minutes; and should also preserve the data on the card. Then re-insert the card into your M8 and see if it reads properly. If not, you may at that point want to copy the data on the SD to your PC while you can. You may need to resort to formatting the card, than copying the data back to it (I've had to do this at times).
I haven't seen any other solutions, or explanation of what is causing this.
