My EX4100 is configured to RAID 5, with Drives 1 & 2 are 4Tb and Drives 3 & 4 are 3 Tb.
All are Western Digital RED Drives as well.
All has been working fine until recently when Drive 3 Failed and whilst I ordered a replacement, I’ve notice that the Volume has completely gone?
All Hard Drives are showing ‘Healthy’ but ‘Undefined’
It appears that according to the main home page, all files are there somewhere, but how do I install Drive 3 new hard drive and keep all my files?
Quite worried as we have a lot of photo’s etc from Family and when the kids were young that I can’t lose.
I’ve uploaded images of Screenshots and SMART Data from each drive if it helps.
Any help would be greatly appreciated.
