Need Altos Diagnostic disk

Help! I've been trying to recreate an 8" floppy from the Altos Diagnostic disk .tdo file recently added to the Commercial CP/M Software Archive site (http://www.retroarchive.org/cpm/) so I can try to diagnose a hard drive problem on my ACS8000-10A, and have so far been unsuccessful. I've been using a Shugart 800 8" drive connected to a PC/AT floppy controller with a 34-to-50 pin adapter, and have been wearing myself out with Teledisk, Anadisk and 22Disk for the last few days with no luck. I think I've got the adapter pinned correctly since I'm able to use certain functions OK, but not make that disk. When I try to use Teledisk, it tells me the .tdo source was a 3.5" high-density FM formatted disk (?), and when it tries to write out to the new disk, it comes up unable to find any of the sectors. Has anyone out there been able to do this, or know of another source for the Altos Diagnostic disk that has the hard drive utility? Thanks, Richard Lynch
