S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) scans

SMART scans are a quick way to tell if a hard drive is failing.

You can test most hard drive formats via Ubuntu's built in SMART scan (in Disk Utility). Or try GSMARTControl.

Common SMART signs of HDD failure:

• Read error rate
• Reallocated sector counts
• Spin retry count
• Command timeout
• Reallocation event count
• Current pending sector count
• Uncorrectable sectory count
• Drive life protection status
