ZIP disks that I format under Win 98 and Win 2000 cannot be read by each other, although with a little playing I can often read them in FreeBSD. Here are my fstab entries for ZIP disks: I just keep trying them until I find one that works for any particular disk. The basic problem seems to be that each OS creates a partition table that the others consider illegal. /dev/afd0s4 /zip msdos rw,noauto,longnames 0 0 /dev/afd0s4 /zipu ufs rw,noauto 0 0 /dev/afd0 /zipx msdos rw,noauto,longnames 0 0 The /zipu entry is obviously not relevant to your problem, and I don't remember which of the other two works with which OS. Try the one you haven't tried already. Also, I have managed to successfully reformat a Zip disk by using dd to create an image of a blank factory formatted disk, then writing that image to the disk to be formatted. The technique doesn't always work, which suggests that it shouldn't work at all and I don't know what I'm doing but am getting lucky... > Alan Tsang [...] > vulpecula# mount_msdos /dev/afd0s1 /zip > mount_msdos: /dev/afd0s1: Invalid argument I was successful when I got up to afd0s4. If you look at the partition table for the disk in question, you will see why. Win 98 puts the data in the first partition, Win 2K puts it in the fourth, or maybe it's the other way around. - Bob To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
