[SOLVED] Check Disk on SD/MicroSD Card?

[anxiousdog]

I have a microSD in my Blackberry that somehow got corrupted. My Blackberry says that I need to run a disc check for errors and try to fix them. I am not sure how to do this in Ubuntu (Ibex).

Any help?

I have a microSD in my Blackberry that somehow got corrupted. My Blackberry says that I need to run a disc check for errors and try to fix them. I am not sure how to do this in Ubuntu (Ibex).

If the card is using FAT/FAT32/VFAT filesystem (Most likely), plug it into a card reader/writer, plug that into your Ubuntu system (or enable Disk / USB Mass Storage Device mode in the Blackberry, if such an option is available).

Your card should now be visible on the desktop; right click it and unmount it.

Open a terminal (Applications-Accessories-Terminal) and give the command

sudo fsck -a /dev/sdd1

(Replace /dev/sdd1 with the actual partition device for the micro sd card). fsck = File Systen ChecKer.

Note that there is a (small) chance that you can lose data by this; it _may_ delete corrupted file entries.

If you have any doubts about which device or file type or so on, the following information (with the card plugged in) will be helpful for a quick response when you post back

sudo fdisk -l
mount
dmesg | tail -20

If the fsck is successful, it will not return any output.

Post back with more details (as above) if you have any questions.

Thanks!

This is the error I get with the fsck:

anxiousdog@ubuntu1:~$ sudo fsck -a /dev/sdg
fsck 1.41.3 (12-Oct-2008)
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdg
/dev/sdg:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

This is the error I get with the fsck:

Try

sudo fsck -a /dev/sdg1

Usually, the device will be /dev/sdg, and the partition /dev/sdg1.

That was it! It repaired 8 bad sectors and deleted the offending file(s). It's working great now!! Thanks so much.

Hello,

I am also needing to do the same thing but am not sure which device is the SD card. Would you be able to help me out? Would be very much appreciated.
The only external hardware device that I is plugged in is the SD card.

Device Boot Start End Blocks Id System
/dev/sda1 1 6 48163+ de Dell Utility
/dev/sda2 * 7 9054 72678060 7 HPFS/NTFS
/dev/sda3 9055 9315 2096482+ f W95 Ext'd (LBA)
/dev/sda4 9316 9729 3325455 db CP/M / CTOS / ...
/dev/sda5 9055 9315 2096451 dd Unknown

Many thanks in advance.

Unfortunately, I can't see it either. Try the below commands in the terminal (Applications-Accessories-Terminal)

a) Unplug the device
b) wait 10 seconds
c) plug the device back in, then give this command, and post back the output

sleep 10 && dmesg | tail -23

d) Also post the output of the command

sudo fdisk -l

(That's small letter "L", not "1")

FYI: It is a 2GB MicroSD card plugged into the computer via SD adapter card.

Thank you again for your help, I really appreciate it.

Cheers,
