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...
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.

is something failing?

I've got an issue i'm hoping you guys can help me with.
I've got a stock froyo 2.2 rooted device.
just recently i've been having issues with my apps.
I back up my SD often so i formatted it and reloaded the data.
This helped until the first reboot then i started having issues again.
The device would show internal apps only, sometimes taking up to ten minutes to load the storage apps.
In the market i cannot download/install apps, even the ones on internal
(sometimes taking several minutes to install)
I've attempted to unmount the SD card but it hangs.
t it hangs when i try to use apps2sd, using my phone as a disk drive, checking disk usuage on both internal and storage, etc.
But i have full access when i use file managers and also when i take the card out of my phone and plug it into my computer. I see everything and everything works.
i have also noticed that it reports the internal memory wrong, sometimes it'll be 50mb's sometimes 130 mb's. All within hours of not doing anything.
i made a nand backup so i'm doing that now, maybe i forgot to clear cache or something last time?
any ideas would surely help, in all honesty it sounds like my internal drive is failing and i hope thats not the case.
thank you

Media Storage data clears on its own (sdcard not emmc)

Just recently started running into problems with my media storage clearing data on its own. One minute everythings fine the next all my music is missing and I have to reboot the phone to get it to rescan the sdcard to get my music back. Has done this on stock sense as well as CM 7.1 so its not a specific ROM issue. Its getting annoying as it happens at least once a day and the rescan takes a long time to complete as I have a ton of music. Starting to wonder if its my sdcard going bad? Its a Sandisk 32GB that I've had for over a year with no problems, have the exact same card in my tablet with no problems. I see there is a fix for teh same problem on emmc storage but not sure if this is the same thing happening here.

does it happen ever day at the same time? or is it random just once a day. if its a set time then i would say its an app. if its random then the card might be going bad.
i have a suggestion. place the card in a reader on a pc and copy everything off of it. do a full format now just a quick format. place everything back on the card and see if it helps.

No its random times. I thought about re-formatting the sdcard but I'm at work and don't have my usb cable with me. I will try that tonight.
I've had CM7.1 installed for about 2 months and was having other issues with it. When this started 2 days ago I decided to restore a Sense backup to see if it would fix it but the same thing started happening after about 6 hours.

Okay it just did it again. HTC Music Player says no music found and when I open the Gallery there are no pictures. Right now it shows only 268 KB of data so its been cleared. Thing is I can access the sdcard using ES File Explorer and can play music with any of the players, HTC, Mixing, ES File Explorer Player, through it.
Tonight I'm going to reformat the sdcard and do a factory reset on the phone. Maybe even just down load the RUU and start over. Something is definetly corrupted.

yeah it might mean your sd card is going out. i would try the format thing first. then maybe a full wipe of the phone and a fresh install of a rom.

I reformatted the sdcard 3 times and then did an extensive wipe of the phone and reinstalled wildstangs stock 4.08 ROM and over night the media storage deleteed its data again. I not totally sure its the sdcard thats the problem and I'm going to try the fix posted for the same problem for the emmc storage and see if that works.
Edit: after reading the emmc thread again there is no fix person who posted it said teh problem came back after 2 days.

[SOLVED] MicroSD to Internal Storage swap not working

Hi,
I was running Flex ROM w/ the MicroSD swap Mod. I shutdown the device and took out the memory card. I used the card for transferring some files. After I inserted back the card and turned on my device, the A100 was no longer detecting the MicroSD swap Mod. I tried to install a new ROM, Green ICS, but it is still not working. The Internal and SD storage are reflecting the Internal Storage. I have set the permission correctly on the install-recovery.sh but I cannot get the MicroSD swap to work. Could anyone please help me with this?
Thank you.

Are you sure you set the right permissions? If you used Root Explorer, all the boxes must be checked. Also, have you tried running the script on boot (using script manager)? You could even execute the script manually.

Since this started after using the card outside of the tab to transfer files, I would suggest checking it for errors, or even formatting it and trying again. A bad removal from a PC can cause this to come up, it seems to happen occasionally on all devices when the card is removed and used on either another device or on a PC. Android won't always notice something is wrong, just won't mount it without reporting errors or things like that mount swap script will fail as the mounting isn't completed on the external SD, so it can't swap mount points (one is missing).
I say bad removal from PC because, windows in particular, will allow you to unmount for removal while STILL writing to it, which makes no sense to me. In my experience, even in linux, the file transfer dialog will say its complete, however the card is still being written to for up to a few minutes afterwards. The card reader I use has an activity LED on it, and I don't even attempt to unmount (or remove in windows) the device until after that has stopped blinking for a few seconds. Removal while still writing can cause filesystem errors that android will usually pick up, but not always.
If possible, try the card in another android device and see if it mounts.
If not, copy all of your data off to your PC, then format it FAT32, then insert into the tab and see if it picks it up.
If not, insert it into the tab and see if it will allow formatting from there.
If not, insert it into another android device and see if it will allow formatting from there.
If not, perhaps wiping in CWM or TWRP will allow it to be mounted.
If recovery will not mount it, even after ALL of the above steps, then the card may just be bad, its flash memory, it happens. A recovery log would help if this happens, and point out why it's failing. ADB shell can then be used to attempt to repair it by e2fsck for error checking, and mke2fs to format it. Final last ditch is zero it out and format again. That should overwrite any bad areas with zeros and "hide" the bad data by writing zeros over it. Takes a LONG time to do this though, roughly 20 minutes per 6 GB. But before we ever get to needing to zero it out, the other tools will report something like a bad super block which can easily cause failed mounts and won't always be reported in android.

Thank you for the replies. I have already reformatted the microsd card. It is actually read by the tablet and no problem using it but I still cannot swap the memory. It was working before. The permissions are correct. I've set it with everything checked for rwx. After rebooting, my internal memory is still the same but the SD storage becomes a duplicate of the internal storage. I have tried using script manager. I'm not sure though if I ran the script properly. Is there any guide on running the install-recovery.sh on script manager? Thank you again in advance.

To run it manually in Script Manager, just select it and click run (make sure you are browsing as root). You could also use Root Explorer (a bit more simple) - Simply tap it and choose execute.

Thank you for the response again. I tried executing it on Root Explorer but nothing happened. It says install-recovery.sh was executed but after restarting, nothing happened. My bootloader is unlocked and I'm using TWRP 2.1.1+. Both Flex Reaper and Green ICS ROMs no longer works with the MSD2INT Mod on my tablet. I'll try reverting back to HC then re-do the whole process of unlocking bootloader and rooting. If anyone has an idea or similar issue, please assist. Thank you.

If you use Root Explorer to do it, it will not work after a reboot. You would just execute it and use it from there (and re-execute after each reboot). Script Manager is best since you can set it to automatically execute the script on boot.

Thank you. I tried using Script Manager on /system/etc/install-recovery.sh and set SU and Boot then saved it. I rebooted but still not working. I'll just try from scratch and see if I get it working again.

I added an edit to this post
longest edit ever
Which explains the steps for both methods of using this script, acer stock/modified or AOSP based which uses script manager. Give that a read, it's quite detailed and boring, but it works.
This is also going to be added into the A100 guide as I get around to it, for anyone else having issues. Mainly, make sure the permissions are correct if it's not working, and you're giving it a minute to show up.

Thank you to everyone who replied. I was able to determine the issue and fixed it. It was a problem with my microSD card. pio was right. The card was corrupted. It was being mounted and detected in the ROM but I was not able to mount it on the recovery. It seems it is not read during boot up and it only gets mounted when the ROM is loaded. I tried reformatting it using the Windows format tool but it still didn't fix it. I was able to use the SD Formatter v3.1 application to fix the problem. The microSD to internal storage mod is now working. I'm back using the Green ICS ROM. Thanks again for the help and suggestions.

[Q] Cyanogenmod inverted storage on computer

I've been using CM10 and now 10.1 for a while now. I like it alot but im having a little issue...
I've searched XDA and found a couple of mention of this issue but no workaround or more info than the usual "yes, i'm also having this issue".
When i connect my phone to the computer, the SD card and internal storage are inverted, yet they report proper sizes.
I wouldnt mind if it was only a cosmetic issue, however i'm having issues copying files on my internal memory because my SD Card is full...
For exemple... when i plug my phone i see "SD Card" with 346mb free out of 59.4gb (using a 64gb sdcard) and i see Internal memory as 8.41gb free out of 12gb. If i want to copy a file that is bigger than 350mb on my internal memory, i have to go into "SD Card" and copy it there and then it fails to copy saying there isnt enough free space.
So yeah, while the cosmetic inversion doesnt bother me, the fact that it's checking for the required free-space in the wrong place before copying is a bit annoying.
I'm using my SD Card for music storage, i like to keep things separated and well sorted... so right now, my solution is to delete enough stuff on my SD Card so that it has more free-space than the files i want to copy on my internal storage
Any workaround other than that?

I'm not sure if there's a workaround but you could try mounting through recovery?
It sounds like a ROM problem, did you clean flash CM10.1?

I did do a clean flash. Over the holidays, i played around with AOKP and CM10.1 as i had issues getting my Wifi to work on CM10.1 and AOKP was working fine (ended up breaking in AOKP after the holidays too, had to change my router's setting from simple WPA to WPA2, but thats another story). So while playing around, i ended up wipping the phone a few times.
Sadly, i don't remember if the issue was also present in AOKP or if it was just CM10.1
I'm using TWRP, nothing shows up on my computer when i plug the phone while running TWRP. So i'm not sure...
Just for reference, here's two other posts with the same issue, both on CM10.1:

As for TWRP, there should be a mount option.

For TWRP, there is a mount button, but it doesnt seem to be there for USB mounting. I couldnt find the option to mount anything on USB...
I backed up everything and ill do a complete wipe now, just to see if it fixes it...

Mount storage perhaps? Or mount internal/external.
I'm downloading a big file right now so I can't check but will check later if you haven't got it.

Well good sir, it seems like your initial assessment was quite correct. After wiping everything (Factory, cache, dalvik, format internal) and re installing CM10.1 latest nightly, my issue is fixed.
Now im reloading everything using Titanium Backup, hopefully i get all my settings back, without restoring the issue... :laugh:
Thanks alot!
