Hey everyone,
I just got one of these today:

see where it says dev sda ? thats physical drive zero which has a read error on that sector.

My question is this: I have RAID00 set up, but don't really understand it well. This is how my disks are set up:
Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/VolGroup00-LogVol00 1886608544 296733484 1492495120 17% / /dev/sda1 101086 19877 75990 21% /boot tmpfs 1684312 1204416 479896 72% /dev/shm
that is not how your disks are setup, thats how your FILE SYSTEMS are setup.
that dev/mapper thing is a LVM volume. you can display the physical volumes behind a LVM with the command 'pvs'
Which one is having the trouble? Any ideas so I can swap it out?
raid0 is not suitable for reliability. if any one drive in the raid0 fails (or is removed) the whole volume has failed and will become unusable.
