Low Level Format cancelled; HDD capacity becomes 0kB!!

[blackbirdz]

I have a Disk Array that I set it up as a JBOD (12x 4TB). I connected the array to the host via Adaptec RAID storage controller. When I was configuring the array at BIOS level, I did Low Level Format to one of the drives out of curiosity. When the system is still formatting the drives, there was a blinking red at the screen Not to cancel the format is still in progress. It was still at 1% progress, so I cancelled it anyway since there is nothing wrong with the drive. However, after I cancelled it, the disk is recognized by the system, but it was greyed out and the capacity then reported as 0kB and it seems like there is nothing I could do with it. Anyone can help how to restore the drive to the working state?

Thank you.

If you have data you need on it I would suggest looking at data recovery. With jbod you probably know you need all drives for the system to work. Depending which extent in the jbod you have started to format will determine how much data you get back.

Was the original jbod hardware or software based, window or other os?

If you decided to try formatting the drive, it means there wasn´t data in them.
So, what happens if you try to format it again ? I´m not sure, but maybe the Adaptec controller locks the drive somehow, and cancelling the format did not unlock it.
