Lost RAID5 on Thecus

Trying to rebuild lost Raid5 on Thecus

I have lost a raid 5 in a 4200PRO and now I am desparatly trying to revive the Raidset.

What happened: The Raid5 over 4x 2TB WDGreen Disks degraded and I accidently marked the wrong disk as spare (this was definately my mistake, failure before always happend on drive #3, this time it was #4…), next boot the raid was gone.

[tried to fix the problem using Linux commands but to no avail].

Has anybody any experience how to get further than this?

Yes, but the success depends on what exactly was done during troubleshooting. Unless the rebuild was forced on a wrong disk order, Home NAS Recovery is a definite answer to the question.
