2 drives bit the dust this week. Both are the Caviar Black 1.0tb WD 1001FALS drives. Both were in an external USB case that supports up to 2tbs. I originally thought the case was bad so I ordered a new one. No Go. Took the drives out and attached one to an internal SATA controller - Bios will not pull up the info from either drive and the WD drive checking software says no wd drives found - error 201 - Other software like testdisk will not locate either drive. On my windows 7 laptop each drive needs to be initialized but shows 0bytes and will not let me initialize either drive. So here I am a year after these drives were purchased and they were fried by lord knows whatever. The external case is fine - power supply is fine - have tried 2 cases an external SATA to USB and internal controllers - so my only conclusion is this. Sounds like neither drive is spinning up - I can hear a power on sequence but no spin up and if you hold the drive no centrifical forces. What is the next step to check these drives before I RMA them. They actually contain 600gigs each roughly of professional video data files and editing that I may or may not be able to duplicate.
I have read several posts about the power boards being replaced or at least checked to see if the board is functional. Don’t want to void a warrenty at this juncture. Any help here would be welcome!
