I have a workstation that uses an adaptec RAID 71605 controller with 4x8TB WD drives in a RAID5 config. One of these drives failed, and after replacing it and rebuilding the RAID, a lot of the data stored on the RAID is corrupted. The Hyper-V machines do not start any more, and a lot if graphics are just broken or have a lots of artefacts.
I have but the controller in a different workstation, with the same result. I then swapped the controller, but the data is still corrupted. Checkdisk and rebuilding the array did not help
Now I am very curious as to why that happened?
The controllers only job is to assure that a drive failure is non-critical, and that was not the case here. Is that something "normal" that can happen? Is there a way to protect for such errors? And most importantly: Is there a way of recovering the files?
