I am using Mandrake 9.1 and my zip drive is not working. It actually spins up the cdrom when I mount the zip. Here is my fstab config.
fstab
/dev/hde3 / ext3 noatime 1 1
/dev/hde1 /boot ext3 noatime 1 2
none /dev/pts devpts mode=0620 0 0
none /mnt/cdrom supermount dev=/dev/scd0,fs=auto,ro,--,iocharset=iso8859-1,codepage=850,umask=0 0 0
none /mnt/floppy supermount dev=/dev/fd0,fs=auto,--,iocharset=iso8859-1,sync,codepage=850,umask=0 0 0
none /mnt/zip supermount dev=/dev/sda4,fs=auto,--,iocharset=iso8859-1,codepage=850,umask=0 0 0
/dev/hdf1 /num2 ext3 noatime 1 2
none /proc proc defaults 0 0
/dev/hde2 swap swap defaults 0 0
It looks fine to me and it worked under RH 9.
