IDE drives not detected by BIOS

Postby Mikeo0302 » Thu Aug 11, 2011 7:52 pm

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?

Sounds like a hardware problem. Could be one of the PATA drives has a problem, or the onboard PATA controller has a problem.

First, try each PATA drive on its own. If neither works, try them in another machine. That should at least narrow down the problem.

Thanks for your help. The problem appears to have resolved itself overnight, but worried that it may happen again.

Scratch that, just tried to boot into mint 11 (installed from the cover disc of LXF), gdm login screen froze so I forced a reboot, and again the PATA drives are not detected. What I didn't mention at first (I didn't think it would be relevant) is that the first time I booted into mint, it froze up and it was after forcing a reboot on this that the problem first occurred.

The drives are as follows:

80GB PATA master: Windows Vista
320GB PATA slave: Linux Mint 11 and Crunch Bang Linux
500GB SATA (socket 2): Media, although I believe my GRUB is installed on here for some reason

Try booting with just one of the IDEs and then the other. Do this a few times, it sounds like one of the drives may be on the way out.
I cannot deny anything that I did not say.
