I had a HDD failure in Disk 3 of my RAID6 array of my TS-431P2.
NAS: TS-431P2 8GB
Firmware: 5.0.0.2131
HDD: 4 x Seagate ST3000VN007
RAID: RAID6
Failure: Drive #3
Initially it reported my RAID status was degraded, then it said Error after I removed the failed drive #3 replacing it with a similar model Seagate ST3000VN006.
I tried to recover RAID group, but I got an error "Failed to recover storage pool...".
Other points to note, the status next to HDD #1 & #4 is blue, the status next to HDD #2 & the new HDD #3 is purple. I also have a busy activity icon with
I'm at a loss on how to proceed to get back my RAID6 array and data, any help/guidance would be greatly appreciated.

Strange... raid6 should be operating even if 2 disks are gone.
A purple disk means that disk is not member of raidgroup!?
So no idea what has happened at your NAS. Best is to contact QNAP support.
After replacing a faulty disk there is no need for a "Recover Raidgroup", a rebuild should start automatically.
So my guess is that there happened more than only a disk fault.

A raid is never a substitute for backup! Never!

Did you hotswap the drives(good) or shut the NAS down when swapping the drives(bad)?

Re: TS-431P2 RAID6 Failure - HDD Fail, RAID Group Error (not active)
you have all disks desynced from each other (see event counter), hence there will be no rebuild
here is what a healthy RAID6 should look like

So what is the best method to salvage data from these drives? Is there any recovery software I can run on another machine to facilitate this?

Re: TS-431P2 RAID6 Failure - HDD Fail, RAID Group Error (not active)
best to contact a data recovery service..next time have external backups at all times
alternatively contact QNAP, events are only minimal drifted..but QNAP support is a safer bet than back and forth in a forum (external backups at all times still stands)
