You could definitely check the disk SMART data.

If you use ubuntu desktop, run the Disk utility in ubuntu:
Disk utility - SMART data

If you use a server, you can install smartmontools:

sudo apt-get install smartmontools

sudo smartctl -a /dev/sdx

where you substitute "/dev/sdx" with your drive.
