Folks, i installed a new drive in my array in April (disk4).

I thought all had gone well with the disk addition, until i saw a red X beside the drive when using the GUI this morning.

Says 'device is missing (Disabled), contents emulated'

I read a similar post on the forum by Barnito, from April 2020.

I followed some advice from that post - reboot & see if the drive goes back online.

Having rebooted, my new drive is showing up as 'unassigned' and can choose 'Mount'

That worries me :-

1) does it suggest that UnRaid thinks the drive is empty ?

2) might 'mounting' drive re-formatting ??

 

I DO NOT want to lose that drive. Its data, both personal & business.

 

Whats your advice ?

 

A) would i try to copy the data off the drive, since its currently being emulated ?

B) would i go ahead and mount the unassigned drive to my disk4 slot, in the hope it doesn't re-format ?

C) anything else ?

Emulated disk is mounting so you can rebuild on top, disk looks fine but there are several UDMA CRC errors, so you should replace the SATA cable before rebuilding.

The procedure to rebuid the disk from Parity is described here : https://wiki.unraid.net/Manual/Storage_Management#Rebuilding_a_drive_onto_itself
