Do you try the way used in redhat, unmounting all of the disk drive's partitions, then
# badblocks -ws /dev/fd0

for sure, remember to unmount the filesystem first.

There is a command called badblocks that you might want to do a man page on.

You can try this to detect bad sectors (Assuming this is what you want) without bringing your system to single user mode

if your disk is /dev/hda

# dd if=/dev/hda of=/dev/null ob=1M

watch for I/O errors or something alike

hello

in order to run a disk surface check you should:
1. boot your system into runlevel 1

2. umount you partition/HD that you wish to check for bad-blocks,( you can run e2label /dev/hda2 - and you will get label of your partition/HD

3. run: e2fsck ???p ???f /dev/hda9
the -p is for repair, the -f is for force ( where /dev/hda9 is the partition that you wish to check

god luck
