Description of problem:
Not all IDE drives are visible to fdisk -l.

I have three drives, two on the primary IDE controller, and one as master on the secondary IDE controller. Only the two on the primary IDE controller show up in fdisk -l.

All three hard drives are visible in earlier kernels that map IDE drives to hda hdb hdc etc. With this kernel, they are mapped to sda sdb but there is no sdc.

I initially encountered this problem in Ubuntu Hardy 8.04. When I first attempted to install Ubuntu Hardy, it was on the master on the secondary controller. It installed but failed on reboot. So I swapped IDE cables, and installed on the master on the primary controller. While it now installs, it still does not recognise all three drives.

Running Fedora Core 8 exhibits the same symptoms of not making all IDE hard drives visible. I suspect that were I to attempt an install on a drive on the secondary controller, Fedora would also fail.

Another configuration that also failed in Ubuntu Hardy is two drives, one as master on the primary controller, and the other as master on secondary controller. Only one drive is visible.
