I'm attempting to make a backup of my Osborne 1 system disk(s), and am so far unable to do this. My machine is upgraded with double-density drive capability and I've tried using both double-density and regular Osborne-1 CP/M v2.2 system disks to start the Copy program (rev 3).
Both disk drives pass tests with the Dysan Interrogator disk, they both seem to be working fine. But when I try to copy from A: to B: (or vice versa) it never gets past the reading stage of the first 9 tracks. When it goes to write those tracks to a blank floppy, it just says there is an error (ERROR IN COPY - please try again). It does this on any floppy disk I try so far, single- and double-density. Formatting doesn't work either, it just sits there and returns to the main menu.
The whole double-density thing seems to be a possibility, I don't know. The system and utility disks I have are all written on double-density disks it appears, even the single-density system disk looks to be written to a DSDD disk, if that means anything. I'm wondering if maybe the DD upgrade is conflicting with the Copy program or something. Have no idea and I'm just grasping at this point.
I would just write them from IMD or TD0 images in MS-DOS, but I've never been able to get that to work on any of my machines. It just gives me a bad sector error or does nothing at all. So as it is, I can't make any kind of floppies for my Osborne. The disks I currently have were made for me by another member here, and I'd like to become self-sufficient!
Am I missing something here? Thanks for any help!
