DITT station is up and running! Here is the first dump:
http://www.sendspace.com/file/tvf1mtedit: CRC errors on tracks 33-34. Hopefully the problem is with the disk and not the drive.
My 5 inch drives are all 2D though, so I can only read 2D (360KB) disks. I'll try to find a 2HD drive sometime.

On the USB drive issue, all I have done is read PC-98 floppies at 1.2 and 1.44MB size, which the 3-mode drive handles fine, especially with Omniflop.
Yes but some protected disks don't use the standard 1.2MB (1024 bytes x 8 sectors x 77 tracks x 2 sides) and 1.44MB (512 bytes x 18 sectors x 80 tracks x 2 sides) formats. I was under the impression that USB drives can't read those. (Actually it may be more of a Windows problem than a USB problem.)
Maybe some of your unreadable 3.5 inch disks are just using a non-standard format?

About DITT - I have had no luck, even having built 2 pretty old PCs and tried various PC 5.25 drives. Are there some tricks you could share?
Check your jumpers! Make sure the pin 34 behavior is set to Disk Change, not Ready.
Also check your floppy cable. At first I couldn't read A: and thought my drive had died, but the drive was actually mapped to B: because I was using a straight floppy cable.
