Hi guys, firstly I am quite new to the word of NAS so I'm looking for some help restoring my NAS/RAID back to a working state.
I have been running a LS-QVL firmware 1.68 with 4 x 3tb Western Digital WD30EZRX drives in RAID 5 for over a year without any issues. A few days ago I had a power outage, when I turned the NAS back on after power was restored I was getting an error E30 and a message stating drive 4 had too many bad sectors and the RAID was running in degraded mode. At this point my files were still accessible.
I then purchased a new Western Digital WD30EFRX drive to replace the old one, installed the new drive then hit the rebuild RAID button. This took roughly 24 hours to finish and when complete I was left with another error message this time stating drive 3 has too many bad sectors and again the RAID is in degraded mode. Now whats different this time is that when I open the web settings menu under storage and in the RAID Array section it is saying that Array 1 is not configured whereas last time my RAID 5 array was visible. Above that in the Disks section the status of Disks 1,2, & 4 are Array 1 and Disk 3 says Error.
Currently none of my files are accessible. This has me very worried.
Also it seems because the system is saying Array 1 not configured the "rebuild RAID" button is grayed out and not accessible.
I am wondering if I buy another replacement drive and install it into the NAS will I be able to rebuild my RAID array again without data loss? I would greatly appreciate any help/advice given.
