Does anyone know if I should be able to use the Shuart 400L floppy as
a replacement for the H-17-1 drives? I'm having some problems with a
pair I got off of ebay. I thought I would be able to use them since
they appear to have the same specs as the Wangco and Seimens drives
with just a different door latch. I had read that they have 40 tracks
instead of the 35 that the older 400 model had. When I received the
drives they had an additional 2" x 2.5" board (with a CAP, a diode,
several resistors, a 74LS86 and a 74LS00) which converted a twenty pin
connector into the standard edge connector and power cable. I removed
this and was able to properly connect it in my H17 case to my
hard-sectored controller. The id was set to 1 (third drive), another
drive is the last drive on the cable and has the terminating resistor
pack. When I try to boot from them, the light comes on, but I receive
a '?Boot error' message. It doesn't make any clicks like my other
drives do. The disk is spinning, but I don't hear any head movement.
This behavior is the same on both drives. Does anyone know if these
drives are not compatible with the heath controller? Or maybe some
other setting is off, both drives did come with the ID set to 1, but
one drive had a '1' sticker on the front and the other had a '2'
sticker? Or maybe I got two bad drives?

Thanks,
   Mark
