Diskcopy used to work on the old uPort release, but not on the later ones. I haven't tried that under xenix because it is so easy the copy media routines in the system. Just fire up the sysadm shell, go to media, go to duplicate. It reads the disk into a file, you don't have to do it, and it lets you make as many as you want before reloading the next source. -- Bill Vermillion - UUCP: uunet!tarpit!bilver!bill : bill@bilver.UUCP

MS and PC-DOS 3.30 doesn't care that it's a DOS file system or not. I use DOS 3.30 diskcopy to copy anything that isn't copy protected. Diskcomp can be used to verify the process as well. SCO distribution and Minix distribution disks are very happy with being duplicated under DOS 3.30 diskcopy. // JCA /* **--------------------------------------------------------------------------* ** Flames : /dev/null | Xenix is the ONLY thing ** ARPANET : crash!pnet01!jca@nosc.mil | Microsoft did right. ** INTERNET: jca@pnet01.cts.com ** UUCP : {nosc ucsd hplabs!hd-sdd}!crash!pnet01!jca **--------------------------------------------------------------------------* */

After reading 4 or 5 answers that were amazingly complicated or assumed you had something called DOS :-) I decided to make a suggestion - how about dd? It is what I always use. Just dd from the floppy to a file on the hard disk and a second dd to make the copy works ok or floppy to floppy to floppy if you have two drives. To be more efficient I suggest you specify a blocking factor that is a multiple of the track size. For example, for a 15 sector/track disk, something like: dd if=/dev/rfd096ds15 of=/tmp/caca bs=30b would work fine. -- Phil Hughes, SSC, Inc. P.O.

This is one of the major differences between PCDOS software and the Unix/Xenix world. You are licensed the software in such a way so that if a diskette went bad, or you had a fire, or the dog ate them. you call SCO, and for a small media charge they send you a new set of disks. In any case, if you do want to copy them look at dd(C)... -- Mark J.

I suggested diskcp(C) to Jim in email. As I did earlier (isn't net.latency annoying? :-( ) The other thing I always suggest is to format the media with dosformat(C) instead of format(C) since older versions of format don't have the -v option, which makes them just a little worthless to call directly.

It's been a while sisnce I've used Xenix, but I recall seeing (and using) SCO Xenix's doscp command for making distribution disk backups. This was documented in the manuals (can't remember where.

Not any more. We misplaced our development disks a short while ago and I called SCO to see about getting a replacement set. I was told that as of a few weeks ago they will no longer replace your media for $50 or whatever it used to cost. The best they offered me was to sell me a new package at half price. I am becoming more and more dis-illusioned with a company I used to recommend enthusiastically.

It is what I always use. That is exactly what diskcopy does (at least older versions). It was just a shellscript that used dd.

The disadvantage is that dd copies the whole disk even if you only have one tiny tar file on it. Tar recognises the end of the archive and stops there. The method I use of backing up a distribution is to completely install everything including net, multiport drivers etc., and then backup the whole thing using cpio to tape (always assuming you have one, of course). If you then create a boot floppy (with cpio on it!) you can reinstall after a complete crash in a tiny fraction of the time it takes on floppy. SCO Unix with dev sys can be reinstalled from scratch in under an hour. (What! SCO Unix crash?! you say) -- Paul
