I was handed a Seagate NAS with 4 HDDs set up as RAID5. One of the drives failed: won't spin up, clicks, etc. The other 3 drives are fine. They spin up, when connected via USB, the data on them is clearly visible with a hex viewer.
Seagate has instructions for restoring a failed RAID5, is calls for a new drive, among other things. The problem is that a crucial [ rebuild ] button is missing from the interface and Seagate has no further instructions except to call their data recovery service, which is $$$$$.
My question: is there software that can do the following:
(1) Rebuild the drive given 3 other drives connected via USB (I took the drives out of the NAS). (2) Mount the resulting software RAID5.
I have access to Mac OS, Windows, and if need be Linux machines. I'd prefer a solution with fewest question marks for safety of the entire array. Note: the files which the user seeks to recover aren't JPG, XLS, and the such. They are highly-specialized format not included in disk scanners. Which is why mounting the resulting software RAID is a requirement.
