Just performed a clean install with 65 and then applied sp5. The WD 80gb
disc is being used a sys with the remainder as another volume. The problem
here is the slave disc ont he same IO channel is a WD 160gb disc and will
not partition using nssmu.

Each time I try and create the partition the error "Device deactivated"
error message is displayed on the console.

I tried making an NTFS partition to try and make sure the disc isn't
faulty. This worked..

Any ideas?

Are IDE (not SATA) discs of this size supported?
