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] "SD Card mounted as read-only"?

Hi,
I'm posting this issue second time. I have a class 2 SD card with almost 1700mb of ext3 partition. the problem is that my SD turns to read only when accessing some files from my sd card. it says in the notification SD card mounted as a read only and then say "tap" to resolve the card responded unexpectedly.
tapping on it sometimes help if i remove the files that I was trying to access that created the problem. otherwise it mounts it as read only.

Hi, you sure your card is a genuine one? The problems you are having are identical to what I had. Turns out my 32gb card was in fact an 8gb card, and the problem was when capacity was reached it would go to read only. The only way to rectify this was to take the card out, place it in my PC card reader right click on properties of the drive and run the error checking tool. Hope this helps. Got my money back anyway thought £36 was a bit cheap lol! Try writing a large file to the card using your Computer, this should give you an indication if the card is genuine or not.

Card is genuine. I have placed my card several times in my brothers htc hd and formatted it through windows. its almost 8 gb i checked it on windows. last time I deleted a folder which has wiered name as if the folder was corrupted. I deleted that folder n it was running fine again. but its back again.
mine came with telus, so it should be genuine. what does class signify? like i have class 2, what does it mean?

CLass is the speed of read and writes.
I recently had a problen like this it turned out to be a corrupt file in the .secure folder used for apps to sd.

then I guess its because of corrupt files but why is it so often specially when I copy something from windows.

I had this problem once after disconnecting from a Windows PC, simply connect the sd car directly to a computer and run the windows verification tool, it finds the corrupt file and your sd card starts working again

hey i recently had the same problem ,, but i figured it out and this method should work fine...!!
>First of all you should know how this problem has occurred..??,
well the reason is, we all connect the phone to system in usb mass storage mode ,,but while removing we'll only give safely remove in the system and forget to do the same in the phone ,,,trust me this the core for this problem....sd-card cannot be fully unmounted by system ,,, so you have to manually do this by your phone
so if you are using the sense rom ,,after ejecting the disk in the system ,,,in your your phone's notification area
in ''connect to pc'' menu select charging only .....this will completely unmount your memory card .
>if you are using non sense rom ,,"turn off the usb" mass storage
do this every time you connect your phone to the system ..!!!
ok now solution for your problem..
>reboot your phone to recovery mode using rom manager...
>select partition menu
>now select mount usb storage ,,,
>now you have tow options
1. either you backup every thing and format your sd-card (recommended)
or
2.mount your sd-card and check for errors in windows,,,
this should fix your problem ..
remember ,,next time when you are connecting your phone don't direly unplug the the cable..!!

The Class number represents a multiple of 1 MB/s
So if 2 is written on ur SD card then it means that its capable of a read speed of 3MB/s

- Not always true, its happened to me on several occassions when not connected to PC etc... Flickie HD caused mine
If you have a mac the fix is - disk utilities - repair card
Full format I found to be better though

[Q] Pictures being deleted

I am basically having an issue where I can take pictures with the stock camera, but if I plug the phone into my computer the pictures wont be there. And then after disconnecting the phone, the pictures will have been deleted from the DCIM folder. Oddly enough though, after a reboot, it will function normally for one cycle of (taking a picture, viewing it in windows explorer, and then disconnecting the phone). Anything after that and no "new" photos will show up in windows explorer.
I was running Mikg 2.55, but in hopes of it simply being a bug I have wiped multiple times and tried a different ROM. The issue is still identical though. My only thoughts left are a possibly faulty sd card at this point, but it is odd that everything saves and works fine on the sd card as long as I don't plug it into the computer and enable "disk drive".
Thanks for any advice or input everyone.

did you try a different sd card?

I have not yet, I unfortunately do not have another sd card available at the moment. But I have the feeling that is ultimately what it'll come down to, to try and narrow the problem.

If you can get everything backed up to your computer, try formatting the card & only move back the necessary files.
It could also be your computer or something on your computer. Does it happen if you mount as disk drive to another computer?

I have backed up the SD Card and formatted it multiple times, the symptoms remain the same after the format. I've dealt with corrupt sd cards before and this is odd in how it acts.
So if I use a file browser on the phone and create an empty folder, it won't be there on the computer when I connect and use as "disk drive". The folder is essentially deleted the second the phone is plugged in. But, if I create the folder from windows explorer onto the phone, and then unplug it, the folder is still there.
I don't have a second computer to test it on, but this does seem like a rather odd problem....

I think you have something set on your pc that is acting up with the phone. I would look through your user access and controls and see if anything strange has access to things its not supposed to.

That was my thought as well, I've noticed that I can take pictures on the phone and the computer is unable to see those photos in windows explorer. But when I disconnect the phone, the photos show back up in gallery and android file explorer. If I restart my phone, then the photos will show up in windows. Of course, then the process repeats for any kind of new picture (or any file created on the phone side).
Also, windows seems to be prompting to scan the sd card for errors most of the time now when I plug it in. That may be an indication of it thinking files are corrupted. I also loaded windows into safe mode to try and rule out any outside program influence on the windows side, same symptoms occurred though.

I have a very similar issue where any pics I take show up as corrupted files when I plug the phone in and sync it. When I do, I get the popup telling me I need to scan my card and it always finds errors in the cache files for pics in the MIUI folder and deletes the pics that gave me problems.
The whole time I can see them in the Gallery, etc, but not on my computer when the phone is sync'd.
If I don't do the scan, when I flash a new version of MIUI, they're fine, until I take more pics, and then it starts all over again with those

Update: Got around to plugging the phone into another computer in order to rule out any software issues. The issue remained the same.
But, finally got a hold of an old micro sd and transferred over all the files to it. Changing out the sd card has fixed the issue, there are no more pictures being deleted or windows errors in regards to corrupt files.
As odd as this was with the previous sd card, I have no choice but to believe it is faulty beyond repair. I have attempted to reformat it multiple times, quick and full formats. Also let windows do a full scan for bad sectors on the sd card, but in the end the problem still remained.
I believe I will step up to a higher end memory manufacturer for my next sd card, in hopes that I can avoid this happening in the future. Just as an FYI, my current sd card was a 16gb San Disk (Class 4).

>: Maybe it's time for me to replace my card too. Hell, it is 2 yrs old.....

Yeah there is some bug in the phone when creating new folders. What works for me is that create a new folder don't rename it add files and rename it later. I hope that helps.

It's happened to me ever since Google disabled write to external SD in android 6.0. Unfortunately all you can do is make the folder on the device itself or flash a kernel that disables write protection.

Thanks Guys , but what about file copying its also take forever !!!

Bad cable maybe? I can copy files just fine. The only problem I have is with creating folders with custom names.

I've been having those same issues: creating a folder takes 30-60 secs. I expect MTP (or whatever) to be slower bit that seems a bit ridiculous. I think it only happens on the first access as subsequent folder-creation goes more quickly.
I've had files "sorta" copy but I think that was a permissions issue; seems to work fine after I somehow (I wish I could remember how so I could tell you) got the prompt to grant access (I'm no longer thinking MM's way of handling permissions is a good idea--I'd rather get the prompts on install rather than not at all).
This is on two brand new phones with their respective cables and 128GB UHS-I Class 3 cards.
I did just copy my initial TWRP backups from it just fine, only took a couple of minutes over a USB2 connection.
I think I was setting the storage location to the SD Card in Titanium Backup when I got the clunky permissions-granting thing popping up; perhaps try that.

Lineage on S5 - No folders on PC

Hi folks,
Lineage 16 (latest version) is now installed on my S5, however when I connect the USB, the phone just shows as 'SM-G900F' on my W10 PC and cannot be expanded, basically no Phone and Card folders.
I can see them in the phone no problem, but once I connect it, I am not prompted with the usual message on what I want to do, like file transfer etc. and on the left menu appears only the model of the phone.
I had no issues when I flashed the original firmware, so it must be related to Lineage.
I also installed the Android USB drivers, but no go.
Changing the USB Preferences, to PTP or File Transfer only allows me to see the phone folder but no SD.
I also tried a new SD, no success.
Any thoughts?
Thank you,
Alex

I have re-flashed everything and started from the beginning.
lineage-16.0-20190918-nightly-klte-signed + open_gapps-arm-9.0-mini-20190921
SanDisk SD Card 32GB, either way I try to format it does the following:
Phone Storage: attempt to invoke virtual method 'java.lang.String android.os.storage.VolumeInfo.getId()' on a null object reference.
SanDisk SD Card unsupported
Portable Storage: When I hit format, it says: Your Card is ready to use - I click Done but still the cart shows in the Storage area as portable Storage SanDisk SD Card Unsupported
The card is OK, also because if I flash the original ROM the same card works perfectly and shows up in my PC too.
This is very annoying, I am stuck on this for days and even trying other cards I get the same.
I hope you can help me to resolve this matter.
Thank you!
