Western Digital Blue WD3200 issue

Hi new to the board

Trying to find out more on troubles with WD Drives

In the past year while servicing equipment I have noticed failure of hard drives in produces like Toshiba and Acer. Surprisingly the hard drives are Western Digital, but I do have a Hitachi with the same issue. The last few was a 250 in Tashiba and the latest is a 500 Scopio Blue in a Acer.  The computer come from two differnt areas that report no problems and I have checked for proper electric service and surge protects which they have. Both drives are not recognized and the last one with the 500 gig repeatedly rebooted until I removed the drive.

Serveral years of experience and service Apple to, sorry.
