Computer: Dell Precision T7400 workstation
OS: Windows 10
Hardware RAID (Dell's SAS Configuration Utility)
4x 1 TB Hitachi Ultrastar drives (2x in a RAID 1, 2x in RAID 0)
The RAID 1 has the OS installation, while the RAID 0 was where I stored video files.
The RAID controller is giving an error message saying one of the RAID 0 disks failed (see BIOS_Error.jpg). It gets past the BIOS into Windows 10 (kinda) but Windows says it can't boot all the way. When I go into the RAID controller interface, it shows 3 disks working fine and the last one as missing/failed (see RAID_Controller.jpg).
What's interesting is that, when I took out the failed drive and attached it to a second desktop I have, the second desktop's BIOS said it recognized the failed disk.
At this point, I'm just wanting to restore the RAID 0 and get the video files off of it. I wasn't backing them up, and this is a "lesson-learned" experience.
My question is: If I have another 1 TB hard drive laying around, could I clone the failed disk to it and use the second disk to recover the RAID 0? I have a spare hard drive--1 TB WD Caviar Blue--that is working fine. From what I can tell, it has the same specs as the Hitachi (same RPMs and same cache size). Can I possibly clone the failed Hitachi drive to the WD drive using ddrescue or something similar? Or should I consider professional data recovery options? I want to recover the data on the RAID 0 if at all possible, and if I can do it myself that would be great. (And no--I'm not keeping the old RAID 0 around; I'm going to replace it with a RAID 1 ASAP.)
Thanks for your help! Let me know if you need any more information.
