Most new PC drives also make assumptions at what signals are used for what. For instance, a drive I used recently assumes that activating the motor on signal also selects the drive. But that's small fry. That same drive thinks there's always a disk in it once connected to the SGC. It also only works right with DD disks even though it's a HD drive. On the PC two signals are used (three in a ED drive) to communicate the density and presence of a disk. This is normally set by jumpers on older drives - no such luck on the new ones, although most actually have sensible defaults. In cases when you deal with drives manufactured to a particular narrow spec, all bets are off :-( Nasta
