My main box has three hard drives, two PATA in a master/slave configuration, and one SATA. I use the SATA exclusively for media storage, but it seems that the BIOS is now only detecting the SATA. This means I get error 21 from GRUB and cannot get into any of my OSes.
I replaced the IDE cable, and have checked that the controllers are active in the BIOS but there is still no luck and the sockets are displayed as [Not Detected] in my BIOS.
What else can I try?
