After all the recent talk about how to duplicate XENIX distribution disks with DISPCOPY and dd, I attempted to dupe my 2.3.2 Xenix disks and install using the copies without success. MS-DOS v3.3 DISKCOPY command gives several "bad track on side 1" warning messages and says "the disk may be unusable". Sure enough, it is unusable (N1 copy goes crazy and others give TAR checksum errors. I then installed a minimal runtime system using the originals and proceeded to do the following: dd if=/dev/rfd096ds15 of=/tmp/xxx bs=15k format -f /dev/rfd096ds15 ; dd if=/tmp/xxx of=/dev/rfd096ds15 bs=15k No error messages while making the copies (80 records copied message only), but N1 copies would not boot, and others gave tar checksum errors. Any ideas on what is happening here? Maybe I should just order a COPY II PC DELUXE diskcopy board from Central Point. I am very leary about not having a backup copy of these disks especially when the Xenix complete s/w is so $$$. ray@stat.fsu.edu ray

The DOS "DISKCOPY" command really only works with DOS diskettes. To use "diskcp", insert the diskette you want to copy into your floppy disk drive and enter the following command: diskcp -f -s -96 This will copy a 1.2 MB diskette and format the new diskette before coping the new files to it. For other disk sizes, enter the command "diskcp -u" which will give you all the options for diskcp. -- Tim S.

I have used the DOS diskcopy program to copy Xenix disks on several occasions. It works just fine. The target floppy must be formatted first, though. I have run into problems when using the "format while copying" option. --jim ------------- James B.
