R Studio Auto Detect

Post by sweetspud » Tue Jul 08, 2014 8:16 am

I have a Thecus N5200 with a RAID5 across 5, 1TB drives. I ran into trouble when I tried to migrate from 4, 1TB drives to the fifth. The migrate took place over a day or, so. It went from 0 to 100%. Upon arriving at 100%, the alarm sounded, indicating a degraded condition and the data was not accessible. According to Thecus (after several remote-access recovery attempts), there were some pre-existing bad sectors that caused the migrate to fail. I have been able to see my folders and many of my files (photos & music) - complete with metadata and file names, but when they are opened they are either incomplete or unable to open at all.

I cloned all five drives and had some difficulty cloning drive 4 (to a lesser extent) and drive 5. Drive 5 took considerable effort to clone and many cloning softwares were unable to clone it.

I am trying R-Studio. The five drives are connected to SATA ports inside the Windows machine. I am running R-Studio from a CD. I built a Virtual RAID and have chosen "Auto Detect" to find the RAID parameters. It has been approximately 12 hours and it is at 11 MB Processed and 22% Detection Rate. Is this OK? Should I continue to let it process??

I know (think) the parameters to be:

Block size: 128
Start sector: 1975995
Rotation: Backward (dyn. disk)

I definitely know the order of the drives and the RAID to be a RAID5. The Block size, Start sector and Rotation is from RaidReconstructor - I'm not sure if Backward (dyn. disk) is a proprietary naming or what the equivalent might be in R-Studio. I scuttled the process with the RunTime suite because they cannot recover EXT systems.

Any help/advice would be much appreciated!!

Thank you SO much for you interest!!

Unfortunately, R-Studio needs a consistent RAID with all disks to automatically detect RAID parameters. I think you should let the detection process finish, but if the RAID inconsistency is high, the result might be disappointing.
