RAID0 Recovery from a WD EX4 NAS
Posted: Sat Jan 02, 2021 7:00 am
Hi there,
I am planning to try to recover data from a WD EX4 NAS.
The situation: I had a disk failure. I shut down the NAS, replaced the broken disk with a spare disk (same model, brand new) and rebooted the NAS. However, the NAS do not trigger a rebuild and was put in status FAILED. The "broken disk" is still readable (I was able to clone it without any error).
I can exclude an error with the SATA ports as swapping the disks within the NAS lead to the same issue on the same hard disk.
So as I am going to connect the disk to a linux PC to investigate the raid using R-Studio my main question for the moment is:
Am I correct that I need to connect the disks as normal SATA disks without using any RAID functionality of the BIOS? Because as per my understanding initializing the disks using the BIOS software raid would destroy the data on the disks.
Best regards
Michael
