Thread: Kaypro 10 Drive Format

  1. #1

    Default Kaypro 10 Drive Format

    I recently acquired a Kaypro 10 that's in really good shape. It boots off the hard drive (which appears to become A: ). There also appears to be a B: (as shown by the "survey" command). I ran a read test of the disk using "check" and it seems to have 4 heads, 17 sectors, 306 cylinders. I can do a directory of drive B: , but I can't copy a file to it. When I try it says, "INVALID FORMAT". Should I try reformatting drive B: ? I can't seem to figure out how to do that...

    Hmm...It seems to me that both drives have a different format. (I am not going to use actual CP/M format names, as I have no clue about them, but will use DOS terms) It is like trying to copy a 360K disk to a 1.44MB disk with the DOS DISKCOPY command. It just doesn't work. But be sure to keep up with the thread, one of our CP/M gurus will be around soon. I think you should reformat the floppy drive.

    Oh, and notice that when you type a colon and then a parenthesis or question mark, you get a face. Just put a space imbetween a colon and another letter AT ALL TIMES. We all figure out what you are trying to say, but it took me awhile. Just click the "edit" button to change that.

    I'm no guru, but...

    The LL formatting software for the K-10 automatically partitions the 10Mb hard drive into 2x 5Mb partitions. CP/M assigns drive letters at boot time, starting from the boot drive, which is always designated A:, whether booting from hdd or floppy. When booting from hdd, the first partition becomes A:, the second partition is B:, and the floppy is C:. If booted from floppy, the floppy drive is assigned A:, the first partition is B: and the second partition is C:. If your Kaypro is factory stock, this should work, but if it's been modded in some way (hardware and/or software), things may be a little different. From your drive parameters, it sounds like the stock drive, but if it's unable to see the B: partition, you'll need to d/l a copy of the reload set from Dave Dunfield's site (http://www.classiccmp.org/dunfield/img36925/system.htm) and LL format then re-install the software. If there's anything you want to keep, be sure and save it to floppies first. Check all 15 user areas for interesting stuff. The CP/M command is USER 1, USER 2, etc.

    Oh yeah, when you d/l the K10G reload set from Dave's site, be sure to read the !READ.ME file, which has instructions for re-doing the drive.

    Highly recommended to drop a TurboROM in that puppy, too. Allows using more/different drives, support for more disk formats, more reliable disk-logging, etc... the list of improvements is loooong.

    You can download a copy of the EPROM to burn with a programmer from many places on the net.
