Thanks, I'll try that. The disc definitely is spinning up OK but
maybe there is not enough power for it to function properly. A
dodgy power supply was the problem with my Acorn Winchester Disc
pieces when they arrived.
The terminator I am using plugs into the Centronics "FileStore bus out"
on the back of the E40S, it's just a plug with a bit of plastic housing
around it, nothing fancy. But I might try going back to plugging in the
second terminated drive and see what happens.
Best wishes,
Ian

Since you say the E01S works with a different hard disc, and the E40S
works by verifying it on an MDFS, Occam's razor suggests the following:
* the terminator you've bought is faulty or the wrong one. I can't
remember - what's the terminator connector on the E40? Is it a 50 pin
Centronics socket? If so, you want a bog-standard passive terminator,
none of the fancy ones with LEDs built-in and whatnot. I have loads
here if you'd like me to pop one in the post.
* the cable is faulty
* the power supply in the E40S is faulty. Measure the voltages at the
drive plug, ***but beware of the live mains on the exposed power
supply***. This was a common fault on those power supplies - capacitors
dried out, causing the output voltage to drop. LEDs and stuff would
still light and the drive would spin up, but wouldn't function.
