Aaron Yeung:
|can you please send the scripts :-)

|oh and btw, how do you eject the zip disk? like just umount it then press
|eject?
Sure. Since there was some interest from more than one person, I'll just
post.
1. /etc/fstab entries for ZIP disks:
(These allow you to just type "mount /zip" or "mount /doszip":
/dev/sd0s1 /zip ufs rw,noauto 0 0
/dev/sd0s4 /doszip msdos rw,noauto 0 0
This assumes you stick with the convention of leaving your DOS (FAT)
on Slice 4 (like ZIPs come formatted) and put your UFSs on Slice 1.
2. mountzip (Perl Script -- attached)
Allows you to mount DOS or UFS ZIP disks without becoming root. To
install, "chown root mountzip; chmod 4710 mountzip". Also be sure the
/zip directory exists.)
3. umountzip (Perl Script -- attached)
Allows you to un-mount ZIP disks without becoming root. To install,
"chown root mountzip; chmod 4710 mountzip". Also be sure the /zip
directory exists.
4. make-ufs-zip.sh
Format a UFS in either sliced or dangerously dedicated mode. Personally
I prefer sliced since I use multiple disk formats.
