RAID Drive Continuously Develops Bad Blocks
on May 2, 2012 at 2:50:42 pm

I have a RAID drive that keeps developing bad blocks, and even after switching out drives, I continue to get errors. The message I receive from Drive Genius is: "OWC Mercury Pro RAID Media ("media" is the volume's name) contains to bad blocks. The drive should be backed up and erased as soon as possible."

Here's my current configuration:

OWC Mercury Pro RAID drive (eSata/FW800/USB connections) - Configured as RAID 0
Two Hitachi DeskStar 7K3000 2TB drives.
Sonnet Echo ExpressCard/34 Thunderbolt adapter with Sonnet Tempo SATA ExpressCard/34 Controller Card (using eSata from drive to convert to Thunderbolt connection)
iMac mid-2011 machine with Thunderbolt ports, running most Adobe Premiere and After Effects

I originally had Seagate drives in it back in January, but then put new Hitachi drives in it last month. Its still developing bad blocks though.
