Check if its really a hard disk error or a file system error.


Do a 'fsck' to check if the error is just a file system error.
And then use 'badblocks' command to see if there are any bad blocks in the system.
[If there are bad blocks, then u`ll have to think about replacing the hard disk].
Doing the above two in single user mode should be the best way.

Use the Fedore 5 boot cd ..
In boot prompt type 'linux rescue' and enter rescue mode.

In rescue mode run fsck partionname [ex: fscl /dev/sda1 ] for all partitions and fix the issue.

To get list of partitions use 'fdisk -l'
