I've a Sandisk 64gb class 10 microsd that used to work fine. All of a sudden it has become read-only. I can read all files, but i cannot delete/add any files or format the sdcard in Android, linux or windows. Every attempt to format sdcard fails with 10+ tools I tried on PC (including gparted, fdsik, etc).
Micro-sd has no read-only switch. Is this hardware problem?

I don't know if you have been able to solve this issue, but it is the same as mine.
I can read all the files but I can't format, partition, write... nothing!
I tried any windows or linux app or distribution, Mac and PC, but nothing at all!
My microSD card is a Sandisk Ultra 64GB.
Any suggestion? Buy a new one?!?
Try HDD LLF Low Level Format Tool by HDDguru for Windows (it is for SD cards too, despite the name), and make sure that other cards work with your devices.
Or, are you using a microSD to SD adapter with all devices (Android AND pc)? If so, try a different one - they have a read-only switch. If that won't help, it indeed looks like a hardware problem - is it still under the warranty maybe?
When i had similar problem i went to service center and they replaced it without questions. These cards usually have 3-5 years warranty. give it a try

This was on of the tools I already tried with no success. I also tried different sd adapters on different PC...
I'm really thinking that it is an hardware issue of the microSD card. It should be still under warranty, the problem is that all the files are still there (and unmovable) and there are some personal documents that I'd rather not give around...

Hope this helps someone
I'm starting to get a feeling that if there's the same problem with any device, software won't help. I try to always encrypt my data such as photos and saved passwords, but if OP didn't do it, there could be a problem with making use of the warranty, I have no idea how to help anymore

Hi,
just to advise:
i bought a microSDHC 8gb kingmax Class10,that i swapped with the supplied
one but after only 10 hours of my desire's use, i had a message "sd card appears as read only etc" so it's corrupted(not yet having time to format it on my laptop)
So i put my Sandisk 8gb class4 back, so far 24hours still functionnal
so perhaps a defective one
This has happened to me using my G2. I have gone through 3 SD cards and lost some very important data. It has gone as far as completely killing 2 of them and not being read by computers or data recovery machines designed to get the data back...

a couple of days ago my 16GB SD card went compltely unusable, not recognized by windows or any repairing tool
and yes I always dismount the card from the phone after unplugging the USB cable
Hi, perhaps you could tell us what brands/size were involved(editing your post) if you dont mind
@gtrab : i a newbie for android, is that important to unmount the card after unplugging the usb(shouldnt it be rather before ;-) ?

LOL yes I meant "before"
and yes, it is important to unmount any USB thumb drive or USB card reader before removing it from a Windows PC
I am not sure if this is related or not, but I found Windows trying to use the card to "accelerate windows performance" or something like that (its an option that pops up when any USB gets connected, I never enable it, but I found a windows-related file there and I just deleted it)

Thanks for your tips, it could be useful to avoid corruption
I have been trying to install Android on my HTC TP2 (tilt) for a couple of months and managed it with the last version, 2.2, and it appears to work great. Looks the Dogs B*... Very pleased.
Now the crunch. I can not use it because there is no sound. If there is an alarm, a notification, a call, nothing happens. I have checked the settings and everything is on "SILENT" and can not be taken off..
I have another, less important issue, which may be the cause of the first. The phone states taht there is no music, videos, pictures or documents, etc. Further investigation it states I have no storage card installed. Clearly there is as I use it in the Windows mode and to load Android!
I have seen threads here and there that talk of reformatting the SD card to FAT 16 or 32, but would that then prevent it working on my Windows mode?
Is there another fix, alternative?
It is recommended to format in Fat32, this will not cause any problem to the device, but make sure to back up your files
I had a nasty feeling you'd say that. I have ordered a new, much larger SD card, so will format that and the copy all the files over, that way if anything goes wrong I still have the origional... I'll feed back

Couldn't wait for the new card, so I copied the contents of the current one to the desktop of my laptop. I then reformatted to FAT, though I noticed it was already FAT.... copies the files back, then rebooted in to XDANDROID. I then tried to open the media player. It stated I had no Memory card installed....
It did not work. What next?

OK. My new card arrived today, which is puzzling being a Sunday. That was a FAT32 and I copied the files I had saved on my desktop on to the card, and it works!!! GREAT... Only prob is some files WOULD NOT transfer, the card was locked even though listed as me as the owner, and I don't know how to change that. But it works
The old card. I have tried reformatting time and again. And am in the process of just copying the files back over and will give up at this point. It works in Windows and RUbuntu, if not Android
I do NOT think it is as simple as JUST format to FAT32, as both cards were FAT32 and only one would worked, and that only some, including Linux/Android files at that would copy over. The Android install needs to be less discerning.

A lot of people have had trouble with certain makes of cards (sandisk wouldnt work for me, transcend class 6 did). I know that my sandisk card had a few problems previously and was heavily used.
FAT will not work as DDawg said above, must be FAT32.
What card did you get out of interest?

I do not know what the 8Gb card is as it does not say and I do not recall. the new 16Gb is a Kingston and that works fine, bar it was locked and some files would not transfer.
PS. How do I brows the devices folders.....?
If some files are copying and others not then those files could be the reason the phone is not working. Cards don't have a lock unless it's on a adapter with a lock option. And your mystery of your card coming today is that your card came yesterday but went to somebody elses house lol

The files that did not copy did not do so on the new card which was locked, or so it said it was. I could not fathom out what made the difference between files that copied over and those that did not. The types and permissions did not seem to be the difference.
As for the lock being on the adapter, maybe. I transferred the files over using an adapter and inserted directly in to the laptop. Might try the same with the old card and see if the lock appears, just for curiosity.
As for the post, you may well be right. Beep annoying though as I planned to do it all on Friday! loL

what i meant is that were there only certain files that were copying or nothing is copying in the new card? if there are certain files that are not copying then the problem is with the files and those could be the files causing the problem on the phone and for formatting, if you used a 8 gb card,it formatted in Fat as Fat32 is only there for cards up to 4gb, therefore i would recommend formatting it in the phone as well

Ah, with you.
The files that did not copy, I believe were working fine, because the apps they worked in worked and those that were just documents also worked. now the apps have been copied over without these elements they do not work or work properly. Also some were within the Android OS itself. There did not seem to be any differentiator between those that would and those that would not copy over. I'm certain there is something else.
FAT: Mmm Not sure I want to go through all that again, but I guess i'll have too.!!!! The phone works with my new 16Gb card, and MUST be accessing it because it has ring tones which are stored on the card and it has found my music and videos. BUT it does not see everything and I do not know how to browse the card... It also does not show up within the available memory. Whilst looking better than my WM, it seems a bit flaky
Also i have notices the red light is on the mute button an the rear of the phone.
Just tried to Format the SD Card from within the phone... Won't. Just flashes. Also will not Unmount.

OK, WM does not have a format facility/tool, so I put the card back in the laptop. Deleted it and then put back in the phone. The phone then formate it.
I then plugged the phone in to the laptop and copied all the files over, they all went bar 3, but then when I checked the folders all had gone over without hitch.
I then disconnected and started the phone.
In windows mobile it works, though CoPilot has lost its maps!
My Ubuntu and Android will not start. They stop in the script where it tried to open the SD Card, both of them.
I tried reinstalling Android and got the same problem. Now I am back to base
Back to start
OK, I am back where I started. I raised a different thread last night, because after al this I had a different problem, that it would not boot at all. It would get part way down the script and then stop, stating it could not open the card.
Since I plugged in to the laptop, deleted the SD card and reformatted as per all the threads using gParted. Again to FAT32
Now I am back where I started. Android boots and looks great, but there is no access to the SD card so no ringtones or media and all my files. A phone that won't ring is not very useful!

Hi all,
I have a 64Gig micro SD card that I formatted to exFat on my Win7 PC.
My question is, Why do I have to repair the card everytime I return it to my Win7 PC card reader to move music or videos to and from it?
Fortunately I don't loose any data but it seems like the MS exFat and the Asus exFat are not totally compatible?
Will the constant repairing limit my cards life span or worse maybe permanently damage it?

Are you ejecting the card from the 700 safely or just yanking it out?
Windows Vista/7 scream 'repair' about pretty much every data storage that has been connected to another device. You can actually just click 'continue without scanning'. It will simply proceed to load the device. (Another one of the wonderful features of Windows 7. God I miss XP.)

No, I guess that is a possibility, just thought exFAT was made for removable storage and finished writing to the media when the file transfer was done?

This is exactly what happens.
I'll try ejecting it from the T700, maybe android/linux mount the removable storage differently then windows and I just became accustomed to not ejecting anymore.
Funny though, it never has happened with FAT32, but my video backups are >4Gigs.
Hasn't happened to me yet on my Infinity, but happens relentlessly on my BIONIC. I even formatted the microSDCard in Windows on my computer, and it still does it. I suppose it is because of the file handling in Android, it usually starts only after I've deleted a file in any file manager in Android. And I do a lot of housekeeping on my phone, in terms of junk / old file deletions.
Could it be the same thing here?

Hello!
I am an owner of a 16GB MicroSD card, which I bought from a famous Greek store back in April 2012. Today I want to use this SD to my old X10 Mini phone. I put it and saw it worked, but when I removed it from the X10 Mini and put it back in my CM 9 HTC Explorer it wasn't recognised.
I inserted it to a SAMSUNG MicroSD Adapter and then to my PC and told me that "You need to format the disk in drive H: before you can use it". The capacity of my SD also showed up as 30.6 MB instead of 14.72GB. I tried recovery software such as EaseUS and Recuva, but none of them even recognised the SD. I tried formating the SD with several tools (Windows wizards, Low Level HDD Formatter, SD Formatter even using CWM) but everything failed.
Is there any way I can make my SD card usable again?
UPDATE : Also tried with HP USB Disk Storage Format Tool but it didn't work.

Nah, I think that if it was dead it would not be recognized from my PC at all.
Not true exactly, there are different failure types for SD cards:
Typical failure modes, listed in no particular order, are
Bad spot on the card (might be recoverable, maybe).
Bad spot causing the card to lock up. I.e. once you accessed that bad spot, all read attempts fail till a power cycle.
Device firmware problem causing the device to report zero capacity. This essentially renders the device inaccessible to any software.
So saying that just because it gets a drive letter that it is somehow ok is not really true.
The HP USB utility is the go-to software for fixing thumb drives with bad partition tables. You can also run "diskpart" (on windows) or gparted (on linux) to see if that is what is causing the size misrepresentation.

As I told you in my OP, I tried Low Lever HDD Formater, but this failed aswell.
I've tried 2 different Sandisk Ultra 64GB microsd's...the first I formatted inside the phone.....the 2nd I took straight out of the packaging and put into the phone..in both cases after a random amount of time I found the microsd corrupted. In the most recent case I tried putting some books onto the card via adb push only to have it inform me that the sdcard was a "read only filesystem"....I then went into es file explorer and tried to browse the card...the "Android" folder was still readable but all other folders now appeared to be some type of file because when I clicked on them it popped up a panel asking me to tell it what sort of file it was....text, video...etc.....after rebooting the phone it would not even mount the sdcard.....I've taken it out and put it on my laptop to run an fsck (linux version of chkdsk) on it and it's finding all sorts of issues:
/Android/data/com.sand.airdroid/********.***

As much as I have loved the phone if it's going to continuously lose data I'm going to have to send it back. The first microsd came out of my old phone and had worked fine in it....to avoid issues I let the phone format it....sandisk is THE name when it come to sd cards in my opinion so I have a hard time believing it's any sort of quality control issue...especially since I tried two different cards...the 2nd one being brand new out of the packaging. Comments appreciated.
I am using a Samsung microSDXC 64GB card.
I formatted it on my PC before using it.
So far, I haven't had any problems.

While I'm willing to try it I would think formatting it on the PHONE would ensure it was in the format it needs to be.....however linux by default uses the fat32 (or fat 16/fat12 depending on size of media) filesystem when fat is chosen. It doesn't have support for exfat. I'm going to try picking up a cheap 32gb from PNY or some other manufacturer than sandisk and see how it behaves.
Thanks for the replies!

Do you ever use adb to push files to the phone? It seems whenever the corruption is noticed I have either just put some file on...am in the process of putting files on or just put some on recently via adb push <filename> /storage/sdcard1/<folder> If not what most common method do you use to get files from your pc to your phone storage?

I just plug it in , and Windows 7 mounts it as Portable Media Player - and from that point on, just copy to, or delete from, the folders. Works for both internal storage, and the micro SD. So far no issues. I have a cheap and slow 32 GB card .
Sandisk 32GB class 10 user here with no issues. I did have some issues when I connected my phone to the computer through a non-OEM USB cord though...

My experience was great until last night. I don't know what happened but I downloaded a new app (Cloud Player by doubleTwist) and as it's nearing the end of reading the music on my SD card (a SanDisk Ultra microSDXC 64 GB), it suddenly stops recognizing the files to the point where the phone was no longer reading the SD card at all. I've tried remounting the SD card but to no avail (even after a factory reset). Interestingly enough, I /was/ able to mount it on my old phone (Note 3) and it worked without a hitch, the card wasn't formatted or anything of the sort and the data was perfectly intact. I tried mounting another SD card I had lying around on the Idol 3 and it worked just fine too. So, what the heck? I sent an email to doubleTwist considering that the evidence points towards the problem being a combination of the phone and the app but I'm at a loss here 'cause I don't see how I'm gonna get the Idol 3 to mount my SD card, even if the app is fixed. Maybe get a replacement from Amazon? I'd prefer to avoid that seeing as how my model hasn't been plagued by the issues detailed on this forum (aside from the buggy Tap to Wake function that is).

Yeah I noticed the corruption only seemed to occur when pushing files to the phone via adb. I'm on linux so it doesn't just mount as an mtp device...I've gone to using other methods to transfer files such as airdroid etc and so far the issue has not occurred again.,
Samsung EVO 64GB corrupted
I had a Samsung Evo 64gb for two weeks everything was fine then one day it changed to a RAW format and I couldn't use it. I have tried everything and don't know what to do.
Hi,
Im having some similar issues with my Idol 3 and the SD cards. First I have a 32gb card that was corrupting all new files stored in it... I formated with the phone, and still the problem continues. So I bought a new 128gb (a PNY) on amazon, making sure specs were compatible, and now it keeps unmounting the SD card couple of minutes after reboot or installed.
So far I have tried:
Format the MicroSD in the phone
Format the microsd in the computer (with partition formats Fat32, ext2, ext4)
make the microsd card with several smaller partitions, down even to 32Gb.
restore phone settings.
factory restore the phone.
Test the MicroSD card in several devices (all worked fine).
Even went to cricket wireless and tried the Micro SD card in another alcatel Idol 3 (worked fine there).
So far, nothing seems to make the idol keep the MicroSD working. It just says "SD card unexpectedly removed".
Any suggestions? Could it be the SD card or the Idol 3?
Thanks.

Hi,
Im having some similar issues with my Idol 3 and the SD cards. First I have a 32gb card that was corrupting all new files stored in it... I formated with the phone, and still the problem continues. So I bought a new 128gb (a PNY) on amazon, making sure specs were compatible, and now it keeps unmounting the SD card couple of minutes after reboot or installed.
So far I have tried:

Sadly the answer is "yes"....cause it's more a combination of the two.....I have a samsung 128gb in my idol3 and it runs fine...a 64gb adata also ran fine....a 64gb sandisk repeatedly failed as yours does...and now has failed on a 2nd device so that card is physically bad in some way. You'll basically have to find one the idol3 likes...when in doubt use the brands others have indicated worked for them...I don't recall PNY being listed by someone as "worked for months without issue". I can vouch for Adata and Samsung. An important point to consider is it MIGHT work initially on that idol3 in the store...but more importantly would it still be working 1 month later.....6 months later...etc
I have a 64gb Samsung that corrupted last week after working fine for 4 months. It happened while writing to the SD card. Wife was talking and all of a sudden it stopped saving the pics. Couldn't get anything to read the card so I ended up formatting it in my backup phone. This likely was due to the camera app but thought I'd post just to add my experience
I have a 16gb sandisk from way back in 2012 yet still works lol but I was rinning into some issues this past weekend it kept telling me checking sd card for errors then it would mount and unmount so I rebooted same problem so what idid was to take the SD card out plug it into my PC backup my data even though the data was intact so I backed everything put the card back in turn the phone on and my data was still there I'm not sure if its something related to your issue but right now my SD card is working normally I love it lol
I've got a Scandisk sdxc 64gb since several months in mine and no problem till now.
