Strange things with my hard drive

No greg this is not the case at all.
To quote from the ATA specification:
"A single device on an ATA bus shall be jumpered as master..."
In fact this is documented in
Sometimes however certain drives and controllers don't follow the standards and do
work with cdrom as slave only however the vast majority
will work just fine with cdrom as master.
I have seen machines that become rather unstable when accessing the cdrom if it is
slave and the only device on a cable.
Linux probes for both master and slave on a cable; but success is more likely if
a single device on a cable is master.
One day all this might not matter; when everything truly becomes plug and play but until then,
i'm glad i've put as many machines together as I have to know all the quirks that I have seen.

Regards, Kerry.
