When I installed Fedora on a used disk, it gave me an error message:
“Disk contains BIOS metadata, but is not part of any recognized BIOS RAID sets. Ignoring disk sdb”
I plugged this disk in a USB-based hard drive docking station on another machine that installed Fedora, and used dd to wipe the disk. It took me two days. I had 8 of the same disks that my co-workers used. So I searched on the net, and found there is a dmraid command can remove the BIOS RAID metadata.
[root@localhost ~]# dmraid -r -E /dev/sdc
Do you really want to erase “pdc” ondisk metadata on /dev/sdc ? [y/n] :y
