Try explicitly telling fdisk which device to look at:
Code:
# fdisk -l /dev/hda
Do you get the same error?
Check the system log (/var/log/syslog, /var/log/messages), and dmesg output to see if there is any information there.

I've never seen this one before.

What distribution are you using?
Is this a new install?

Here's what I might try:
Boot your computer from a rescue disk (your install disk will do).
Mount the system drive using the rescue disk.
chroot to the system disk, then try executing the commands that give you the weird output.

If the commands still give strange output then I might suspect a hardware issue (perhaps a bad hard drive that's dying?).

If the problems go away then I would think you might have a bad install.

That's my suggestion. Hope it helps.

Could easily be that your disk is a damaged.
To check this , run a bad-blocks check
badblocks /dev/hda

Then it could be that only the filesystem is damaged (but I don't think you would get this Input/Output error, I may be wrong)
Code:
tune2fs -C 32 /dev/hda2
this will tell the system that /dev/hda2 (your / which includes your /bin) has been mounted 32 times without being checked. By default ext3 are checked after 30 mounts.

Code:
reboot
During the reboot /dev/hda2 will be checked.

Or my last idea would be that you are not using the correct harddisk driver. Is this installation new or is it a new problem?
