SUMMARY: Zip Drive

Thanks to all the replays:

Allan West has some very interesting information on his web-site

Brian Sherwood (among others) suggested to use an application called
MTOOLS that's available at sunsite

Agner Dwight and Stefan Voss suggest to searche the iomega web site.

Actually I sent an e-mail to iomega technical support. You'll find their
answer at the end of the e-mail. But I still have the problem. What
happens is that I'm able to see the iomega driver from the 'ok' prompt
(with probe-scsi) but once the system is loaded the format doesn't see
the disk. Believe me I tried all kind of disks (Mac format, PC format,
using a strong magnet to erase it all ..) but nothing seems to work. I
haven't tried yet the MTOOLS but since I'll update to Solaris 2.5.1 soon
I'll wait until then to use the drive.

Thanks for your help

I understand that you are trying to hook up your Iomega Zip drive to your
Sun Microsystems. At this time we do not actively support this OS, but I
have provided all information that we have on hooking the Zip drive up with
a Sun Microsystems.

        How do I install my Zip Drive on a Sun Workstation?
This document contains the steps that are needed to install an Iomega drive
onto a SUN Workstation.
Supported Drives:
The Zip 100 SCSI drive is supported on the following Operating Systems using
the built-in drivers, which are not provided nor supported by Iomega. Zip
disks can not be formatted using these Operating Only standard, non-write
protected disks can be used.
- SunOS 4.1.1 - SunOS 4.1.2 - Solaris 2.0 How do I install my Iomega drive?
Set the SCSI ID Switch
For SunOS 4.1.1, 4.1.2, or 4.1.3, use SCSI ID 0, 1, or 2. Be sure to select
an unused setting. For Solaris 2.0, SCSI IDs 3 & 7 are reserved, use any
other unused SCSI ID setting.
Attach the Iomega Drive to your SCSI adapter or chain
Create a Device Entry Point (For Solaris 2.0 only). After attaching the
Iomega device and starting your SPARCstation, enter the following command at
the OK prompt: boot -r
Entries for format.dat
Enter the appropriate entry into the /etc/format.dat file. Use the system
editor and be careful not to change other file entries. The entries are case

Solaris 2.0;
disk_type="Zip 100"\
partition="Zip 100"\
        :disk="Zip 100":ctlr=SCSI\

SunOS 4.1.1, 4.1.2, 4.1.3
disk_type="Zip 100"\
partition="Zip 100"\
        :disk="Zip 100":ctlr=SCSI\

Data Disk Preparation Procedure:
1. Insert the correct Iomega disk in the Iomega drive prior to booting the
2. Run the SunOS format program at the # prompt type: format Note: In the
following examples, X represents the sd number shown on your monitor for the
drive that contains the working disk.
3. Select the sd number related to the drive that contains the disk you are
formatting.If the disk has never been formatted, the program should enter
the Drive Type menu. Select the appropriate disk type from the list.
        4. Use the partition sub-command to choose the partition
5. Use the print option to verify the existence of the C partition.
6. Use the label sub-command to write a label on the disk
7. Use the quit command twice to exit the format program.
8. Run the newfs utility to make a file system on the disk. At the # prompt
            -v /dev/rsdXcUsing a Disk:
1. After the file system has been placed on the disk, you can mount it into
the UNIX file system. (Replace mount_point with an appropriate mountable
directory eg. /mnt). At the # prompt type:mount /dev/sdXc /mount_point
2. When you are through using the disk, it can be removed from the UNIX
file system. At the # prompt type: umount /dev/sdXc or: umount /mount_point
3. To check the file system, make sure the disk is not mounted and use the
fsck command. At the # prompt type:fsck /dev/rsdXc
