I'll post update tonight. In short, it works like a removable drive using HD Driver.
Apologize, got off onto other "duties".
This is as far as I've tested.
First, the drive is very fast, with the SCSI controller, nothing like a standard floppy controller onboard.
HD Driver sees the device as removable media.
Don't know much about how the driver assigns drive ID's. HD Driver knows to format the floppy at 512 sectors. Pretty sure that's correct for a floppy.
Since HD Driver doesn't install the device as a floppy, you must format the disk with HD Driver. Which brings up another issue, while the drive (HD Driver?) reads 720/1.44k media very reliable (would not read 360k disk), if formatted the disk becomes unreadable (remove-insert/reboot-refresh).
Didn't get to try the disk on a PC afterwards.
Wondering, I've never modified a PC floppy to work with an Atari, think this may have something to do with the format issue?
I'll swap out the floppy with a known functional Atari drive and test.
The floppy does have jumpers, AIRC, that's one of the easier drives to configure for Atari hardware compatibility.
I'm doubting that would have any effect on the SCSI controller.
Physically, the mechanism attaches below the floppy, offset from the front of the drive, extending rearward enough for cabling.
It's approximately 8mm thick, with rails to mount to standard floppy screw pattern. I'd have to inspect, there is easily enough length on the floppy raisers to take them down so the floppy would fit the existing opening in an ST style case, offhand haven't looked at IC/board component interference. The controller can be removed to relocate, however being the length of a floppy case, it's rather large to do so.
Ideally, the device would make a great external"B" drive. I threw a couple of PD disk and game disk at it with no problem. Ran a few PD apps without issue, other than the program loading extremely fast
Need to check drive jumpers (they look like STD SCSI configurations), the ideal situation would be to have HD Driver recognize it as a floppy device and install it as drive "B", something to ask on Uwe's forum.
As inexpensive ad they are, going to purchase a 3 or 4 more
