I should have noted here that one should always place write
protects tags on your disk when working in an unknown system.
The incorrect terminators, in my case, caused the \WGATE signal
to be low. This erased the data on two of my disks. Luckily, in
my case, both disks had been backed up with my H89LDR so
restoring them wasn't an issue. One needs to be especially
careful with software that one doesn't know what the disk may
contain. We need to save as many of these jewels as possible.
