SD card blank or has unsupported filesystem fix

D200P13 · Jul 30, 2011

4 posts about this and i think i found a way to fix this with windows. it did this to me and worked so thought id share so people dont format the sd card and lose all data.

i put the sd card from my sensation 4g into my computers card reader. in windows 7 i went to start > rightclick "computer" and click manage. i then clicked on "Disk Management" to see what type of condition the sd card was in. it said it was a RAW disk. i started to think and then decided to try a chkdsk to see if it fixes it. to do that i just clicked START > RUN (or START > type in RUN and click the run shortcut) and type in CMD in the box then click ok. now in the command prompt type in CHKDSK X: /R then press the enter key (NOTE: X represents the drive letter). wait for it to do its thing and it should fix this problem.

i am not sure if it will fix it for all cases but atleast it worked for me.

I had this problem only after installing Swift Key X.

Uninstalled Swift Key X , Unchecked fast boot in power options
Powered down phone removed battery for 20 seconds put battery back in
turn on was fixed

If happens again i will try ur method in an attempt to confirm though

yea another thing that has happened was i had to restart the phone a few times and it worked but the first post was a common issue and fixed it when other methods didnt work

Comes up with the SD card is RAW so it can't be done or something :/..
Really don't want to lose the data :/

If you have a rooted phone and your sd is readable by your computer there is no need to format it. Just go to recovery and mount/sdcard.

This problem seems to be a flaw although.

I do not know why there is no proper feature which causes this problem

I think the problem is caused by root access to the sd card or kernel compatibility.

No its actually caused by recovery. Install stock recovery and the sdcard blank or unsupported filesystem error might not appear.:thumbup::beer:

Stock recovery might be the fix, clockworkmod compatibility might be the problem.

Do you have a partitioned sdcard? The CHKDSK command should detect this.

If you can't mount the sdcard using recovery, such as clockworkmod etc, I don't know whether changing to stock recovery will help.

Then whats the possible solution.. I observed one thing which is i flashed stock rom from sammobile and the sdcard used to work sometimes and sometimes it dint.. So i think its nit the sdcard which is corrupted or dead.. Is it coz of rom?

This problem is not caused by CWM or any modded recovery, I know because this is happening to me on my LG Optimus L9 and I have the stock recovery on my phone. Although it is rooted, but that shouldn't be the cause. It's probably a faulty SD card, I have a 32 gb SDHC and my phone seems to hate it, half the time it tells me the card is blank or unsupported filesystem and wants to format it, the other half of the time it sits for an hour or two just scanning the darn thing. Either it actually is a faulty card, or my phone isn't good at reading large SD cards. So much for 'smart phone'...

Definitely the phone. My computer always manages to read the sd card, so of course, whatever happened to my phone is causing the problem. For me, the problem started immediately when I flashed a Rom after root. I didn't wipe my phone before, is that a fix???
