Hi,
I have my unraid server up for 14 days now and added the 2nd disc (Both WD Red Plus 4tb), which should act as my Parity drive. Before including the 2nd Disc to the array i performed a prelcear. Pre-Read running fine up to 40%, then a dd error occured which then leading to a bunch of further errors at approx 4:30 am (see attached log). Next morning when I looked onto my Unraid Server, the disk do not show up as an unnassing device, neither within the preclear plugin. I then attached the disk to my Windows System - Didn't show up in BIOS, but in the Windows Disc Manager (diskmgmt.msc). However, i could no re-initialize the disc there.
It is possible that the Pre-Read killed the HDD?
Could it be an issue with the MB or its ATA controllers? System is a ASRock J3455-ITX.
Any suggestion if there is a chance to recover the HDD?
Thanks a lot in advance,
Alex
