If you did not do a diskpart clean on your 3 good drives, it is still probably trying to do a raid 5 with 4 drives. I think it would load, but then say you had a drive missing. But if you got the 0x9 that normally means all data is lost and you need to start over.
You need to attach the hard drives to the PC running that software. Either with 4 sata ports, 4 usb cables or usb docks, or perhaps two docks that hold two drives or any variation of the above to get all 4 drives spinning on the PC running the recovery software.
Hi All,
I need to run the WD diagnostic tool on my existing drives - these drives were originally setup as RAID 5, then one of them failed and then a few other issues and to cut the story short, I need to now check and see whether those 3 remaining RAID 5 drives are ok. I was thinking to connect them one by one to a PC via one of those SATA to USB connector cables - here is my worry: if I connect them to the PC to run the tool (western digital) is there a risk that the OS will right something on it which may create a bigger disaster.
