As in scsi systems, the last drive on the cable must assume that its job is to terminate the cable and try, by the termination enabled when is either jumpered as Master, or is in CS mode and the last drive, to absorb the echos from the signal transitions.I've never heard of IDE using termination (despite understanding why
I suppose you mean ATA. Even the old MFM drives used termination, as do floppies.
transmission lines need proper termination). There are no termination options on IDE drives, they seem to rely on tolerance (cable length
Yes, there are.
being severely limited, nominal expected impedances for interfaces, etc). Master and slave dates back to when the master drive controlledthe slave drive (the host didn't control both drives).

I've never seen a SCSI cable with crossed wiring. Do you have an example?
Impossible. SCSI uses non-physical addressing, unlike ATA.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
