My external raid enclosure died some weeks ago. I then stored one in an anti static bag, the other was installed to the desktop so the data could be used and added to. Now a new different model raid enclosure has been supplied from an RMA claim.
I put the desktop HDD back into the new enclosure's bay 1, and the stored HDD into bay 2. The enclosure was set to Jbod from the box so I reset this to Raid 1. I think this was the fatal mistake. Both drives are now inaccessible, but are visible to Windows disk management as "unallocated space." I used Partition Wizard to try and recover one of the drives. The partition is now identified as RAW with Partition Wizard able to see the files and folder structure, but Windows will not assign a drive letter until formatted.
The data is precious, I'm bricking it as the files simply must not be lost!! I'm borrowing a large 2TB HDD from work over the weekend to try and copy the RAW partition over to the borrowed HDD. Don't know if I will get access to my files this way yet.
Any suggestions what else I can do? I may have to take it to a data recovery firm and they charge from about £80..
