[Q] sdcard wont mount

Thought I would ask first... my SD card will not mount on my phone. Data seems to still be there but I have a notification saying "sdcard is blank or has unsupported filesystem." Tried to format but the card wont mount on the device. I've tried formatting in the android os and in recovery with errors. Does this mean the SD card is toast? Any help is appreciated. I'd hate to lose all of the data. Thanks.

At work right now and our computers are on lockdown, no external devices can be read. If I can access what should I do? When I tried repartitioning in recovery it said it could not mount dev/block/mm? ?? Or something like that, basically gave me an error. Any advice? Im about to just buy a new card.

You might just need to reformat the card. Sometimes the cards get corrupted. You might even still be able to access and backup the content on the card if a PC will read it. If you have WIndows 7, it might even offer to repair errors on the card. That could also get it working. I'd say reformatting it is a good idea either way.

i just had similar error... try removing and reinserting card. if that doesnt do it reboot into recovery and depending on the recovery you are using go in to mounts and try selecting "mount sd card" that last one fixed my issue.

I ended up just buying a replacement 8GB class 10 card (wanted a higher class card anyways, this gave me an excuse to buy one ). I was able to retrieve the contents of the SD card by mounting it in my computer (vista 32). I didn't try reloading it into my Evo cause now I don't have a need for it. Thanks for the responses though, glad that you guys are here and willing to help. :thumbup::thumbup:
Sent from my Modded Evo... It's easier this way.

microsd card damaged suddenly !!!!

a microsd card 8GB class 4 came with my phone
today after I took a picture with the phone camera I forwarded to see but no sd card
I connected it to PC then the windows asked me to format ... I wondered the the card space became 30.6MB !!!!
and cannot be formatted .
I tried many ways to recover the sd card such as SDFormatter v3 , DriveRestore_Professional , EASEUS Partition Master , and more ... without benefit !!!
can any one explain what happened with the solutions if possible please

Try using the formatting option on your Phone, or you could try CWM to do it too.

Try doing what XD suggested, if that didn't work, try formatting with another pc

I tried to format using CWM and using 3 PC's (win7 & xp) without any benefit

That happened to me once.
if possible You have to connect the SD card directly in your computer (SD Adaptor or any SD card reader).
If you're using windows, you have to go to control panel--> Admins tools, and then go to disk partitions. There you have to identify your SD card on the list and eliminate all partitions that could be on your SD card. Then you have to create a new partition on that SD and the format it.
There you go.

Can you use or format another sd card? the purpose of this is to see whether it's actually the sd card that's at fault here

Maybe, maybe not, if it's not faulty then there's no reason why it wont, and if other users on the thread of whatever ROM, kernel or both you're using have reported the same issue then I don't see why it wouldn't. Given that you've already said that you've tried everything suggested I suspect it's a faulty card, but you're never going to know unless you try.

thanks anyway for you all

Format in linux You must of tried turn you sd card into ram thing or ext overload at lease it will tell you what is wrong with your sd

SD card mount problem please help

I've been searching all over for a couple days now and I can't find any solution only people with similar but not exact same problem I'm having. Out of the blue a couple days ago the fat32 partition on my 32GB class10 patriot SD card unmounted and won't mount at all. However the ext4 partition mounts just fine and continues to work as it always has. I also can't plug the card directly into my PC because the adapter that came with the micro SD card appears to not work. My PC doesn't think there is an SD card in it. I tried it with a known good SD card (the 16GB samsung SD card that came with the phone. Which when inserted into the phone mounts and can be used like expected. No new apps where installed or changes made to my phone or the SD card before it stopped working correctly. The same apps and what not have been in use for as long as I have had the 32GB SD card. In fact the currently in use version of CM10.1 has been is use for the last month with no issue regarding the SD card. When I remove the card a notification shows up telling me to insert an SD card. And when I insert the 32GB card the checking SD card notification shows up an a second or two after the SD card is safe to remove notification shows up as if I had told it to unmount the SD card. If I tap on mount SD card in settings the same thing happens. And it also happens after a reboot. CWM can't mount the SD card either. What can I do to fix it so the fat32 partition is usable again?

Have you tried formatting the SD card in recovery?

As I said I can't mount it with CWM either. The card contains the data for my mSecure passwords as that app was forced to the SD card due to JB changes in android so I can't format it until I can recover the data on it. I need a solution to access the data before I can reformat it assuming that it needs to be reformatted. The SD card was supposed to be this fail safe thing and I didn't need to make backups of it as it was the backup storage stuff. So now I'm all freaking out because I can't access it for all the backed up data on top of the data for one critical app that was forced to reside on it. The good news is that only a few apps data is effected by this the bad news is those apps were all very important. I just don't understand why this has happened. And if using a cloud source such as box will be any more secure and safe than using the SD card in light of this; now I don't trust not losing data in the future on a source that was supposed to not have this sort of thing happen.

Maybe the SD card just went bad. Sorry I couldn't be of more help.

No problem, it's a problem no easily solved, and is a long shot finding anyone who will be able to help. I looked at dozens of sites and forum threads and all sorts of other stuff from goggle searches and couldn't find a solution to get it to mount in either the phone or on my PC to recover the data from it and find out for sure if it is a bad card or not. It might still be under warranty. If it's not I'll be ticked considering how much it cost and how little time I've had it.

Try installing Recuva on your PC, if this program doesn't work for you then you might wanna try another more advanced recovery program like R-studio v6 (Shareware) which is easy to use since it's GUI based.
or testdisk-6.14-WIP (Freeware) which includes testdisk_win.exe for partition recovery and photorec_win.exe for files and media recovery, but it's kinda complicated since it's based on Command Prompt or DOS! so you need to google for a guide for how to use it.

Wow I somehow never got notified of this post seeing as I'm just now noticing a reply from months ago. Yes I still can't mount the SD card. I took it out and returned to the stock one that came with my phone. I still have the card as I need to recover the data from it and if not possible wipe it somehow so that I can warranty exchange it. Please do let me know what your solution is so that I can try it and see if it works.

Refresh my memory on what the problem was. This was a while ago lol.

The SD card won't mount in my samsung epic and my windows PCs. This was a sudden without warning signs and with no apparent cause. One moment it was fine and the next moment poof. I was looking for a solution to gain access to the files on it to recover whatever I can and if possible repair the card so that it works again. Assuming that it's not a failure of the card itself. It is within the warranty and well within the life expectancy of it. So I suspect it is not a failure of the card itself. I have the option of using ubuntu or other USB stick bootable options for tools as needed.

[Q] External SD Card Read-Only Problem

I tried researching this but wasn't successful finding same exact problem or solution. I'm on 4.4.2 Baseband N900TUVUCNB4 rooted with stock rom and ext sd fix. Everything was working fine until recently. My external SD card has inexplicably become read-only, both on the phone and on my desktop. I first noticed this last week when the phone camera began having problems writing to external SD card, and now I can't sync music to card. I've tried formatting on the phone and desktop, both quick and full but no dice. On the phone, I am able to delete individual files or folders but they reappear. On the PC, I can view but get write protect message when trying to format. Anyone else come across this or have suggestions?

Happened with me once with a different phone/OS. Weird thing is that it was only for a particular SD card. I put a different card and it worked.
It turned out to be a problem with the card (dunno how thats possible though).

What's the brand of your SD card?

I have the exact same problem with my SGNote 2 and SanDisk 64gb micro SD card. First I lost some pics I have taken that day. I searched through with a file rescue tool but they were nowhere to be found. Deleted files reappear, and the ones I copied from internal SD dissappear.

I had same problem. But I fixed this problem by formatting my SD card via PC. It is very bad to me Because I lost my some valuable Docs:crying:

Try file recovery softwares, you might recover it.

It's a SanDisk 64gb class 10.

Glad to hear I'm not the only one. Maybe we can share the solution when we find one. I'm using internal memory in the meantime for new media files, but frustrated that I am not able to use the rest of the memory available on my card.

SanDisk works fine for me, maybe your sd card is a faulty one, let's wait for a while here and maybe someone could answer your question and hopefully solve your problem

Thanks, Lorettaa. It seems like that's the only option right now, since I can't find any other info about it on XDA. I know Kit Kat has that design "flaw" where apps can't write to an SD card, but I can't even write to it, modify it or reformat it on a PC. I have full read access to every file, just can't do anything else

I have the exact same problem, i tried many options , used some softwares in windows to format , wipe, fix, modify. nothing works.
One possible reason for this problem is file system errors , which can be rectified using the 'error checking' option in windows and 'fixing the file system errors'
But that doesnt solve my problem, even after formatting using advanced softwares, the sd card is the same - no files deleted, no files added...
The fat as well as ext4 parition is not formattable now in anyway.so the possible conclusion is 'sd card is going to fail'.. Take a backup before you loose the read capability.

Recuva is a good, free tool (from the people that make CCleaner) to deleted recover photos.

And one possible reason for a false error condition is a corrupt system. This is normally an unlikely possibility but it is very likely on devices that have had partition images written to (i.e. a flashed ROM). If you have done all you can to the SD card and if the errors are not only on one SD card then wipe everything and load a backup. If you still get errors then wipe everything and revert to stock to see if they still occur.

No reading sd card

Hi. Picked up this phone a week ago. I love it. I put a sd card in from another phone. I got it in and it sees it but I cannot read it or format it. Does it have to be a certain sd card to work?

Download file Commander and format sd card, if it won't do it, connect the SD to the PC and format it on NTFS:highfive:

I tired pk unzip but there is no format option. I formated the card with my computer like you said but it still doesn't see it.

Can you see a popup informing you about "SD Card" inserted.
You need to complete that step from the notification menu.
Select it as Media Storage for using it properly.

Hi
So try to format it as FAT32

I do get a notification but everytime I use it, it crashes. I tried the FAT32 format but still get the same results. I am trying this with two different sd cards which work fine in my old phone and laptop. I think it's the phone. Some googling resulted in Xperia phones not being able to read sd cards properly.

Ok so I have an idea, have you been on an airport or over a metal detector? If yes, it means that your SD card or phone got demagnetized (happened also to me with old phone), so buy a Sony SD card that resist to them :good:
