G-Raid HFS+ recovery issues

April 19th, 2012, 19:29

Hello all. I am trying to recover data from a 1 TB G-Raid. The raid controller appears to have died, both 500gb disks from the enclosure test as being fine. I am using R-Studio 5.4 for the recovery. The drive was used to save Final Cut video projects on a mac running Snow Leopard. He is very concerned about maintaining the original file structure and file names.

So far I have figured out:
-the stripe size is 512 Bytes
-I have also figured out the disk order
-The HFS volume label (H+...) is located at sector 131105 according to winhex.
-according to ReclaiME the offset is 0

I have tried creating a region in R-studio with a start point of 262208 with a volume size of 1 tb.

Now comes the problem. I cannot get it to give me any good data when I use these settings. Is my math off on the start point? Is there some setting in R-Studio that i'm missing?

Any input or suggestions would be awesome. Thanks everyone.

Switch tools, try using winhex instead. Get type of raid (ie, 0,1,5 etc) and parity as well as stripe size.

Failing that contact DR-Kiev on here, hes the RAID king in these parts.

H+ header should be at 409640. If it is at 262208 there is problem with your config.

Reclaime is not always right.
