- IOMega ZIP Drives
-
- A lot of people seem to be asking on the net (as did I myself) about IOMega's
- great new ZIP Drive, a 100MB removable-media drive costing under $300, and an
- un-precedented $15-20 for blank 100MB disks. So I figured I'd share my
- experiences and information on using them on the Amiga.
-
- Typical Questions
-
- "I just got a ZIP drive, but all of the software is for the Mac or the PC!
- Where can I get Amiga software?"
-
- First, you don't need any special drivers on the Amiga to use just about any
- SCSI device. The Amiga employs something called a Rigid Disk Block, or RDB for
- short, which is standard, set-aside area on your hard drive which contains
- information about all of the partitions on it. When you boot your system, it
- reads this RDB and automatically configures and mounts whatever partitions you
- have.
-
- The same is true for ZIP disks. You simply need to get a program like
- Commodore's HDToolBox to partition your ZIP disks and write an RDB onto them.
- If you are using a non-Commodore controller, chances are it came with similar
- partitioning and setup software. See below for specific information using
- Commodore's program.
-
- "You can buy blank ZIP disks, but they're formatted Mac or PC. Which do I
- get?"
-
- It doesn't really matter because you're going to format them anyway. Unless
- you are using CrossDOS and/or CrossMAC and wish to use PC or Mac formatted ZIP
- disks and it's important that they're already formatted for you, then it makes
- no difference.
-
- "What do I need to use a ZIP drive?"
-
- You need:
- A SCSI controller - Amiga 3000's have built in SCSI controllers - Must
- have a DB25 connector for hooking up the drive. Most controllers do;
- If yours doesn't, you can still use a ZIP drive, but will need a
- special cable. Consult the manufacturer of your controller; It's
- "beyond the scope of this manual".
- SCSI device ID 5 or ID 6 must not be in use - the ZIP drive can only
- be toggled as either ID 5 or ID 6.
-
- "Does AmiBack work with ZIP drives?"
-
- Sure does. You can either save backups as an AmigaDOS file on a formatted ZIP
- disk, or write directly to a ZIP disk (note that this destroys everything on
- the disk). Either method works great.
-
-
-
- Formatting ZIP Disks for the Amiga
-
- Once you have everything hooked up, which we won't go into here, you're ready
- to format some disks! The following information is for Commodore's HDToolBox
- program which can be found on your Workbench 2.x or 3.x install disk.
-
- You do have to keep a couple of things in mind, no matter what HD partitioner
- you're using:
-
- All your Zip disks should be paritioned and otherwise setup the same - The
- Amiga is not quite good at removable media yet, and isn't smart enough to
- handle disk changing if your disks have different partitions or device
- names.
- You can make multiple partitons, but the above note still applies! Make
- everything the same!
- All your Zip disks should have the same partition name(s). This is
- different from the volume name, which is the name of the disk as it
- appears on Workbench, which you are free to change.
-
- Preparing a ZIP disk
-
- 1. Load up HDToolbox - If you have an Amiga 3000 or a Commodore SCSI
- controller, just double click on the program. If you are using a 3rd party
- controller, you must first edit the icon and add a tooltype called
- "SCSI_DEVICE_NAME=xxx.device" where xxx.device is the name of your SCSI
- controller's device, like "suprascsi.device". Consult your manual to find
- this out.
- 2. Click on your ZIP drive in the list; It should come up something like
- "IOMEGA ZIP 100" on either device ID 5 or 6.
- 3. Select it and then click on PARTITION DRIVE.
- 4. Create your partitions and set them up to your heart's desire. I use one
- single partition that takes up the whole disk (2047 cylinders). Turn off
- the "Bootable" flag unless you're really trying to make a bootable ZIP
- disk (which does work fine, by the way).
-
-
-
- 5. Click on "OK" to return to the main screen. The "Status" column should now
- read "Changed", and the button "SAVE CHANGES TO DRIVE" should now be
- active.
- 6. Click on SAVE CHANGES TO DRIVE, and exit the program.
- 7. Reboot your computer.
- 8. WHen Workbench loads, you should now have a "ZIP:NDOS" icon on your
- Workbench (although it might say something else, depending on what you
- named the partition inside HDToolBox, in which case it'll be that name +
- :NDOS".
- 9. Single-click the icon, and then go up to the "Icons" pulldown menu and
- select "Format Disk", and proceed to let Workbench format the disk.
-
- Viola!
-
- You can now use your ZIP disk like anything else. Note that without a
- mountlist entry that gets called in your startup, in order for the system to
- recognize the ZIP drive, a disk must be in the drive when the machine is
- booted so that the Amiga can get all of the information off the RDB.

- Practical Tests
-
- I used DiskSpeed when I originaly got the drive to test it's speed. The
- numbers came up fairly horrible as far as read/write speed goes, but I've
- personally found the drive to perform much better than those numbers. It's
- still a slow drive; It's not meant to replace your hard drive. But it's
- perfectly adequate for most uses; Storing all of your MODs on, or graphics, or
- fonts, etc.
-
- I personally am using AmiFileSafe (AFS) which is an incredible new filing
- system from Fourth Level Development. Among other things, AFS:
-
- Is much more effecient than FFS - extremely fast
- Cannot be invalidated - no more "Drive Not Validated" messages after a
- crash
-
- I have all of my ZIP disks formatted with AFS instead of FFS which is a
- tremendous speed increase. Fourth Level Development is also coming out with
- some added software for removable media drives which will allow you to handle
- things like disks with different partitioning setups.
-
-
-
- If you have any other questions, feel free to to send me mail. I'd be happy to
- try and answer any questions you have; These are great drives. And even if
- they kind of sucked, which I can't say that they do, it's still hard to pass
- up because of the cost. IOMega's got a winner.
