All of my WD drives, 2x WD2500KKS 250G, 3x WD 500AALS 500G drives pass WD’s own DLG tools Extended test several times but one of my 500 drives so far has an isolated sector error under that of HD Tune Pro’s “Error Scan” app, should I be concerned at all here? Thanks everyone.
It’s not unusual to have a sector error. Usually, if you run Windows error checking and scan disk, they will mark and recover data from any bad sectors. That should prevent any further attempt to use that sector. However, if there is an increasing number of bad sectors, the drive is failiing and needs to be replaced.
