ZIP/JAZ Tool 1.4.0 1. General ---------- ziptool is based on the genuine work of Grant R. Guenther and Bob Willmot. As there are still quite some things to do, I decided to adopt this tool and maintain it. For copyrights and conditions of use see the source file ziptool.c.

About jaztool/ziptool ------------------------ The JAZ and ZIP are removable media drives developed by Iomega. These drives, however, differ from other removable media devices: Read/write protection isn't done with a little switch etc. on the media but in software. You even can protect your disks with a password. ziptool makes most of these features available to Linux JAZ/ZIP users (see my personal notes in the 'Change Log' section below for more information). A thing you can't do at the moment is changing the password of a disk in one step as I still don't know how to do this. A workaround here is a two step procedure: First change the protection mode from password write protected to plain write protected and then - with your new password - back from write protected into password write protected mode. Another thing that will probably never work is the read and write password protected mode. Linux requires at least read access to a disk in order to be able to work with it. This version of jaztool/ziptool only supports the SCSI and parallel port drives. The IDE drives are _NOT_ supported and - as far as I'm concerned - will not be supported in the future, unless someone supplies me with information about these drives (most wanted are the commands used for the password protection features). 3. How to install ----------------- Get yourself a copy of the ziptool package (latest version is 1.2) from sunsite.unc.edu or any mirror: it is located in the utils/disk- management directory. Extract the tar archive with # tar xvzf ziptool-1.4.0.tar.gz into your local working directory. This will create a directory named ziptool-1.4.0 which contains the following files: - ziptool.c source - Makefile :-) - ziptool.1.gz man-page (needs more work ...) - README this file 1. Edit Makefile to match your setup. 2. Do a 'make'. 3. If you want to have the binary and manpage installed, do a 'make install'. This will also create symlinks named jaztool and jaztool.1.gz in the specified directories. 4. Change Log ------------- Version 1.4.0 09/25/2002 (Tara Milana) ---------------------------------- Version 1.3 09/25/99 (Aaron Segura) ---------------------------------- Nobody seems to be updating this thing, so *I* have taken the liberty to add 2GB Jaz Support, as well as the -u -m -ld -ud options. I really wanted them, and I'm sure somebody else wants them too. Aaron Segura -> Added -u -m -ld -ud options -> Added support for 2G Jaz Drives Version 1.2 06/24/97 (Mirko Kraft) ---------------------------------- -> Created a README file. -> Added a kernel patch to ged rid of that #@'? eject after each protection mode change. -> Changed the command line interface. I hope it now is easier to understand. The new CLI looks like that: ziptool -e eject disk (same as 1.1b) ziptool -s report protection mode (same as 1.1b) ziptool -ro make disk read-only (was -w in 1.1b) ziptool -rp make disk read-only, protect mode with password (was -p in 1.1b) ziptool -rw remove any protection (was -r in 1.1b) -> Update to my personal note from Version 1.1b: Please Iomega, support developers! Releasing tech manuals won't hurt, but it will pay back! I'm sure you are aware of the number of Linux users that already bought a JAZ/ZIP. Imagine how many more buyers there will be if the JAZ/ZIP are fully supported under Linux (both IDE & SCSI). So please, everyone: Please ask Iomega very kindly to support the Linux community - BUT DON'T FLAME THEM!!! Point out that there are a lot of JAZ/ZIP and DITTO tape users out there who would appreciate Linux support. Version 1.1b 05/23/97 (Mirko Kraft) ----------------------------------- -> Berkeley auto mounter daemon (amd) adds entries with mount type "auto" to /etc/mtab, thus causing jaztool/ziptool to fail when it checks mount points. As "auto" is a mount type not included in mntent.h, it has to be hardcoded. Many thanks to Mark Blair (Mark.Blair@tus.ssi1.com) who discovered this bug. -> Update to my personal note from Version 1.1: Iomega will not release any tech manuals (at least that's what they told me), so I have to take the hard way to find out more about JAZ/ZIP drives' SCSI commands. Note to Iomega: This does not mean I am going to reverse engineer your software (i.e. ziptools). But I will use an ASPI manager that allows me to see what is going on on the SCSI bus - and maybe I can learn a little bit more about your drives from that information. Version 1.1a 04/24/97 (Mirko Kraft) ----------------------------------- -> Boy, did I ever hear of a thing called proc filesystem? Although I use this thing, I entirely forgot it when skipping mount types when checking for a jaz/zip drive. So people with an fstab entry 'none /proc proc' will endup in a stat(none), which will fail of course (note that my entry is '/proc /proc proc', so I didn't see this error when testing). Many thanks to Gerald A. Peters (gapeters@worldnet.att.net) who discovered this bug. He also improved error reporting in this case. Version 1.1 04/17/97 (Mirko Kraft) ---------------------------------- -> Code cleanup -> Improved device checks. NOTE: This tool was originally written for Iomega ZIP and JAZ drives. But now there seem to be more of these drives on the market. If you want a new drive to be supported, add its model signature to the appropriate list (see below). Please e-mail me any changes so I can keep an up-to-date version of ziptool. -> Changed mount check to handle symlinks and multiple names for the same device correctly. Up to now the following was possible (assumed ZIP drive is /dev/sda, medium out of a box): # mknod zip b 8 4 # mount -t msdos /dev/zip /mnt # ziptool -r /dev/sda This would allow to modify a mounted ZIP disk. -> Created a man page Do an 'man ziptool' or 'man jaztool' for more information. !! This tool is based on kernel 2.0.30, libc 5.4.7. !! Personal note: I'm really no SCSI and Iomega hardware expert. I just took over the SCSI calls as found in Grant's original ziptool because they are working. Maybe some day I can get my hands on some SCSI and Iomega specs to see what is really going on here. ++ I had no problem compiling this on Kernel 2.2.5+, libc 6 ++ Aaron Segura
