 |I have mounted a Zip SCSI on my box... But I am not able to mount the
 |disk (msdos format) .
 |
 |Here is what kernel thing :
 |
 |(ahc0:2:0): "IOMEGA ZIP 100 E.08" type 0 removable SCSI 2
 |sd2(ahc0:2:0): Direct-Access 
 |sd2(ahc0:2:0): ILLEGAL REQUEST asc:24,0 Invalid field in CDB
 |sd2 could not mode sense (4). Using ficticious geometry
 |96MB (196608 512 byte sectors)

No problem.  I get this too.


 |but when I try :
 |
 |{114} /tmp#mount -t msdos /dev/sd2s1 /mnt
 |msdos: /dev/sd2s1: Invalid argument
 |
 |Where is the problem ?

Two things come to mind.  First, ZIPs by default come with the
disk-spanning FAT partition in the 4th slot in the partition table.  Also,
the ZipTools will put it there too.  You can redisk/format with DOS and
SCSI drivers if you want.  I personally leave the DOS partitions on 4 and
put my UFS partitions on 1.  Personal preference.

To see where it is:

      fdisk /dev/sd2

If it is in the 4th slot, try:

      mount -t msdos /dev/sd2s4 /mnt

instead.  Of course, whatever device you use, make sure it exists.  If not:

      cd /dev
      sh MAKEDEV sd2s1
      sh MAKEDEV sd2s4
      mkdir /mnt
