If the drives are somewhat recent you can try using SMART to check them. In particular you can use the smartmontools port. You may need to enable SMART on the motherboard. SMART = Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) http://en.wikipedia.org/wiki/Self-Monitoring%2C_Analysis%2C_and_Reporting_Te chnology Syntax is smartctl -t short /dev/ad0[1] smartctl -t long /dev/ad0[2] smartctl -l selftest /dev/ad0[3] [1] If the short fails you know there are problems. Still no guarantee. Still worth to do quick tests first. [2] If it fails, there is a good chance the drive has some sort of problems. [3] Use that to check the result.
