The fsck command checks filesystems (it has different variations like fsck.ext2, fsck.ext3, fsck.ext4, fsck.vfat (for FAT filesystems, which would be most USB drives and memory cards).

I don't know what you mean by an "MP3 storage" but if you wanted to check the filesystem on a USB drive, you would (run the commands in a terminal window):
1. Plug in the drive to the computer.

2. Run: sudo fdisk -l
This helps you identify which device is your USB drive, based on its size, usually. On most computers, this will be /dev/sdb.

3. Run: mount
Look for lines with the device name from step 2. For example:
/dev/sdb1 on /media/C80B-46F1 type vfat
Note the partition device name (e.g. /dev/sdb1) and the filesystem type (in this case, vfat).

4. For each DEVICENAME found in Step 3, run:
sudo umount DEVICENAME

5. For each DEVICENAME found in Step 3, run:
sudo fsck.TYPE DEVICENAME
For example:
sudo fsck.vfat /dev/sdb1

Here, TYPE is the filesystem type from Step 3.

Hope this helps...

You can execute it with:

i.e: fsck.ext3 -f /dev/un_mounted_drive

Be very sure to unmount the drive first before running fsck.
