[SOLVED] Asustor NAS with inaccessible Volume1 ?

[ZoeSmith8338]

Hey guys, I have an ASUSTOR NAS with currently 3 x 4TB WD RED HDDs inside and yesterday one of them gave a failure so I disconnected it and connected it back again (this has happened in the past once and it fixed the issue) but yesterday it made the disk not accessible so I rebooted the NAS. When it came back online the "Volume1" of RAID5 was inaccessible and it has been like that since. Any help?
Thank you in advance!

What specific "failure" was reported if there was such a report?

Not sure about a disconnect - reconnect being a viable fix per se. The first time it worked may be been coincidental with some other failure and recovery.

That said, try again, and ensure that the applicable power and data cables are fully and firmly connected.

Failing that - swap in known working power and data cables.
