ok, i ran the TTP (TechToolPro) sector test on a relatively little used 2TB WD caviar green sata drive which just holds my life's worth of digital photos, no OS. After 10 hours 80% thru, it reported a stretch of 112 consecutive bad sectors and continued examining. A bit later i got a "bad eject" error on the desktop. TTP was now frozen. The drive is suddenly unreadable. TTP forum moderator says magnetic flaking or electronics failure, but TTP could not have wrecked it cuz sector analysis is simply a read function. The great annoyance is how little used this drive is for complete failure, and why while running TTP?
Anyone please?
