Buffer I/0 error on sda2


I recently installed Arch on one of my desktops, the first time there was no problems, however I re-installed it later and now everytime I boot I get:

Buffer I/0 error on device sda2, logical block 0

is there anything I can do to format, get rid of bad blocks etc?

i'm assuming my hard drive isn't dead since it happened after an Arch install attempt?

thanks for any advice

I would probably start by booting a live CD and then running fsck to check your hard drive.

You may want to take a look at the link below if you do no know how to use fsck:

Good luck!

I would run a SMART long test on the drive, this makes sure the drive is not failing and checks for bad blocks.

smartctl -t long /dev/sda
Wait for it to finish and post 'smartctl -a /dev/sda'.
