Timothy:
With the disclaimer that my comments pertain to PATA hard drives and not
SATA drives since I've had no experience with the latter devices, here is my
understanding of HD configuration. I would appreciate your comments on the
following...
1. If the HD is jumpered as Master or Cable Select (CS) and is the only
device on the IDE cable, it doesn't matter what position it occupies on the
IDE cable for it to boot -- it would be considered as Master whether
connected to the middle or end connector of the IDE cable.
2. If the HD is a Western Digital (one that has a jumper setting of Single),
it should be jumpered as Single or CS if it's the only device on the IDE
cable. It doesn't matter what position it occupies on the IDE cable for it
to boot - it would be considered as Master.
3. If the HD is installed at the only device on the IDE cable, it's
considered good practice to connect it to the end connector rather than the
middle connector even though it *will* boot while connected either way. I
vaguely recall there was a ATA specification that cautioned against a
"dangling end connector" but I've been unable to find the reference. In any
event there certainly doesn't seem to be any negative implications to
connecting a single HD to the terminal end of the IDE cable.
4. The only time the position on the IDE cable is relevant is when the HD
has been jumpered as CS and there are two devices on the IDE cable. Then the
device connected to the middle connector is Slave (assuming it's jumpered as
Slave or CS) and the drive connected to the end connector is Master
(assuming it's jumpered as Master or CS). So if inadvertently the HD was
connected to the middle connector while jumpered CS, it would *not* boot.
5. If the HD is jumpered as Slave, it will not boot, period! It's position
on the IDE cable is immaterial.
6. If the HD is jumpered as Master, and there are two devices on the IDE
cable, and the HD is connected to the middle connector of the cable, then
that HD will *not* boot.
