unRAID's signature on the MBR failed


Recommended Posts

Hi,

 

A couple of weeks ago I had a drive suddenly show red ball against. I bought a new drive to replace, but when I run the new drive through pre-clear I am getting the following error:

 

unRAID's signature on the MBR failed

 

The drive then dissapears as an option to pre-clear, although still shows on the main screen under unassigned disks.

 

I thought it might have been the SATA cable so replaced this but I'm still getting the same issue.

 

Logs are attached.

 

Any advice on things i can try, I don't think its anything to do with the disk itself.

As John noted, there's no SMART info available for what I assume is your new disk ... so you've either got a defective drive or you have a cabling issue.

 

Try the cables first.  If you have a PC available with a spare SATA port (or a USB dock, although direct SATA connection is preferable), you might run WD's Data Lifeguard on the drive and confirm it passes both the Quick and Extended tests.
