Dell dimension E520 Desktop with Intel SATA Raid Controller configured for RAID 0 (mirroring).
Initially I had a pair of Seagate 500 GB drives in there, but only after a week, the flashing red ‘drive failure’ Icon was there, indicating that the secondary drive had failed.
In preparation for returning the drive, I put it in a SATA drive enclosure, ran SeaTools Diags on it (passed), and then did a DBAN data erase on the drive with no problems.
After returning the Seagate to my friends at Fry’s Electronics, I put in a shiny brand new Hitachi 1TB SATA drive as my secondary (I plan to make the primary be an identical Hitachi drive, BTW).
The drive re-mirrored itself without a hitch, seemed happy as a clam, then two days later it shows the Hitachi is in ‘failed’ state.
Am I just having bad luck?
Is something killing my secondary hard drive?
Or is this a ‘false failure’? What would cause the PC to think a drive has failed when it has not?
I plan to swap SATA cables and check for BIOS updates.
