Internal and external 1GB Iomega Jaz drives with media. The Jaz drive is a removable storage system sold by the company from 1996 to 2002. Following the success of the Iomega, which stored data on removable magnetic cartridges with 100MB nominal capacity, the company developed and released the Jaz drive. Initially the drive featured 1GB capacity per removable disk; this was increased to 2GB in 1998. The Jaz drive uses a interface, with both internal and external drive models. Iomega produced a Jaz Jet SCSI adapter card for PCs.

Iomega also produced a number of external adapters, including the Jaz Traveller interface that connected it to a standard, and, later, a SCSI-USB adapter and SCSI-Firewire adapter. An IDE version of the drive was planned, but never released.

Having problems formatting disks, it can read a disk but cannot format. Was wondering if its because the original disk is ibm and the other mac formatted. Its a mpc 3000 with a d2 1 meg iomega jaz drive, all disks are 1 meg. Iomega 1 GB JAZ Disk - MAC Formatted. Works in both 1GB and 2Gb JAZ drives.

Contents. Reception The Jaz never attained as much success or market penetration as the Zip drive. While the Zip drive was marketed as a high-capacity for the home and (SOHO) markets, the Jaz drive was originally advertised as a higher-end product.

SCSI interfaces were standard in computers but were rare in the much larger market of end-user PCs, usually requiring an extra interface card to be bought and installed. The rising popularity and decreasing price of / drives greatly hurt the success of the Jaz drive, offering a much lower price-per-megabyte and the convenience of the CD media being readable in almost any standard CD-ROM drive. Problems Earlier Jaz drives could overheat, and loading-mechanism jams could leave a disk stuck in the drive.

Forcibly ejecting a stuck disk could destroy both drive and disk. Jaz drives are hard-disk technology, making them susceptible to contaminants in the drive; dust and grit could be introduced through a hole in the disk case where the motor drove the platters, and any dust built up on the external case could enter the drive with its next insertion.

Additionally, the metal sliding door was capable of wearing the plastic, resulting in debris. Furthermore, the mechanism used to attach the platters to the spindle motor was complex and tended to vibrate noisily. Iomega implemented an anti-gyro device (much like an optical CD/DVD drive) within the cartridge to prevent vibration at spin-up, but this device lost effectiveness with age. As a result, the two platters could lose alignment, rendering the cartridge unusable. The plastic tabs attached to the bottom of a Jaz cartridge could become stripped or broken, rendering the inserted disk physically incapable of spinning up to operating speed.

Legacy The later drive attempted to use similar technology to address the same market segment as the Jaz drive had done. Part of that technology is actually derived from the use of a 'voice coil actuator (VCA) motor to improve the reliability and reduce the seek time of an HDD’s read-write heads' in a removable media cartridge. The other part of that technology is actually derived from the use of 'low-cost, low-load, landing read/write heads with lubricated disks'. Neither the Jaz drive nor the REV drive copied the IBM 3340 in making the heads a part of the cartridge, although the REV drive moved the motor into the cartridge—which even the IBM 3340 had not done. It was left to the drive to move the heads into the cartridge, which increased reliability by essentially making the cartridge an electro-mechanical duplicate of a modern external disk drive.

Hi, I just bought a used Iomega 1 GB Jaz drive on eBay from a very reputable dealer (Elite Auctions) and I can't seem to figure out how to get it up and running. I'm new to these Jaz/Zip drive things and I think it's probably some kind of ID conflict problem. According to the Apple System Profiler, my internal HD has an ID of '0', the internal CD-ROM drive has an ID of '3', and my Microtek scanner has an ID of '6'. The Jaz drive came with its ID set to 'O'.

I changed it to '2', then to '5', then to '7'. But every time I try to boot up, the system hangs, apparently when the Iomega driver extension tries to load (the computer booted up fine with extensions off). I finally had to take the Iomega extension out of the Extensions folder just to get the computer to boot (got kinda scared when the computer finally wouldn't even boot with the extensions off or from the OS 8.6 CD - I had to use an old PM 5400 Disk Tools floppy just see the hard drive). I have all the necessary Iomega software on the OS 8.6 CD, and the System installer even installs the Iomega driver (but not the Iomega extras) during the installation.

I guess I should also mention I have the Jaz drive 'daisy chained' from the scanner (the drive is the last in the chain). And there is no 'termination' thingamajig on the Jaz drive like there was on the scanner before I put the Jaz drive plug in that place. Could that be a problem? BTW, this is all SCSI gear if that's important. If someone has experience with these things and recognizes the likely problem, I'd appreciate it a lot if you could clue me in. - / `-', 'Guaranteed to blow your mind' / I I ::: oo.

' Super Seventies RockSite! Click to expand.It doesn't matter what order the devices are cabled in. What matters is that the device at the very end of the chain-and only that device-be wearing a terminator. (No, the current governor of California doesn't count.) And yes, it can get tricky when there are so many devices using so many different physical connectors. Are you sure that the Jaz drive doesn't have a built-in terminator?

It's been a long time since I last saw one, but it seems to me that it does, and that there is a switch on the drive to enable or disable it. I know that this is true of the SCSI-based Zip drive that I currently have connected to my system. I hate spam, but that isn't really part of my email address. Remove the string 'HatesSpam' from this email address before you use it: Ever wonder what it'd be like to be a blood-sucking parasite? Click to expand.I believe that's it. That first character is a numeral one, and means that termination is on. The zero, of course, means that it's off.

The 'A' stands for 'Automatic', and means that the device will attempt to determine for itself whether the terminator needs to be on or off, and set it accordingly. Try setting it to 1. I hate spam, but that isn't really part of my email address.

The actual switch (as represented by '.' ) was set to the '0' position and that's the only way I've tried it so far.

First things first: if you're trying to get the Jaz drive hooked up to an SCSI bus that already has other devices on it (scanner, etc.), the best advice I can give you - at least to start off with - is to DISCONNECT the other stuff temporarily, and see if you can get the Jaz working by itself first. OK, let's go forward. Before you do anything else, get yourself a copy of the 'SCSI Probe' control panel. If you can't find it, email me directly (the address is a valid one). Now hook up the Jaz drive - by itself - to the computer's SCSI port. The small switch you see with the 'Term' is the Jaz drive's own internal terminator.

It can be either on or off (can't tell from your description above). If the Jaz was the only device that the previous owner had connected, I will hazard a guess and say that it's in the 'on' position. In that case, leave it alone for the moment. Got the Jaz connected?

OK, next step: boot up HOLDING THE SHIFT KEY DOWN to keep extensions from loading. DO NOT put a cartridge into the Jaz drive yet. Do you get a good boot, even if the Jaz isn't there yet? OK, if the Jaz isn't already powered on, turn it on. Now, put a cartridge in the Jaz and let it 'spin up'.

Does it spin up? At this point, with no drivers loaded, it should spin up but it SHOULD NOT mount on the desktop yet. At this point, you should understand that all Mac-formatted Jaz cartridges already have a 'Jaz driver' on them.

Formatted

This is what SCSI Probe is for. Open the SCSI Probe control panel. You should be able to 'see the presence' of the Jaz on your SCSI bus, even if the cartridge hasn't mounted yet. If it is there, you can assume your cabling and termination is OK. If it is not there, time to re-check SCSI address, cabling, and termination. By the way, I would suggest ID #1 or #2 for the Jaz, something low. DO NOT use ID #0 (that's the Mac's internal SCSI drive, if it has one).

If you have an internal CD-ROM, DO NOT use ID #3 (that's reserved for the internal CD drive, if it's on the SCSI bus). DO NOT use ID #7 (that's the ID of the Mac itself). OK, if it is there, the next step is to try and load the driver. In SCSI Probe, you should see an 'upward-pointing' arrow, or a 'mount' button. What happens?

What should happen is this: when you tell SCSI to 'mount', it should scan all devices on the SCSI bus, checking them for disk drivers. If it finds them (it should, as again, all formatted removable media cartridges should already have drivers on them), it will load the drivers and then attempt to mount the cartridges. Does this happen? Does the cartridge mount on the desktop? If it does, GOOD. This is what you want. You now know that the Jaz drive itself is good, that it's properly connected, that termination is correct, that you have a good cartridge in it, and that the Mac will be able to load the drivers and mount the cartridge.

DRIVER NOTES: you can then try rebooting with all extensions loading. Be aware that the Imega driver software you have could be out of date, or perhaps be 'too new' for OS 8.x. If this is the case, you will have to hunt for the correct version of the driver software. If you continue to have problems with driver software, my advice is to NOT USE ANY OF IT, and use SCSI Probe to load the drivers instead. Once you do the 'SCSI Probe trick' the first time, forcing the drivers to load, they will stay loaded until the next reboot. You can then eject one Jaz cartridge, put another in, and it will mount automatically. If you can get this far, then you can begin thinking about re-building your SCSI chain and incorporating the Jaz within it.

If you decide to put the Jaz in the middle of the chain, you should probably put the 'Term' switch in the OTHER position (which I will assume turns OFF the internal termination). Otherwise, you can put the Jaz at the end of the chain.

But if you do, make sure you remove or disable termination on everything that falls between the Jaz and the computer. Final recommendation: if possible, consider upgrading to OS 9.x. John (sorry for the empty previous post). Click to expand.Hallelujah, I think I've finally got it working with the terminator switch set to '1' and the SCSI ID set to '2'. I was able to boot up, get into the Finder without any problem, and access the Jaz drive using the 'Guest' program that temporarily loads the driver.

I've got the daisychain working with computer - scanner - Jaz, which is what I was wanting to do. I also went to Iomega's site and downloaded the latest Jaz drive software for OS 8.6-9.2; it's a few years newer than the comparable files on the OS 8.6 CD.

I may even get real bold and try to see if I can startup from the Jaz so I can have another HD rescue option in addition to the OS CD and the Disk Tools floppy. Thanks for your good help Bob, also you Dave.

Click to expand.Do you think they'd contain 'insignificant' stuff like what to set the SCSI ID to and what to set the terminator switch to? Because I must have read 10 or 12 Iomega manuals and help files on one feature or another that came with the driver files on my System 7.6, OS 8.1 and OS 8.6 CD's plus with the driver software I downloaded from their site and they mention nothing about those two things. I just wonder what kind of setup whoever owned the drive before me had with a SCSI set to O and the terminator switch set to 0. It's exactly the opposite of what works for me. Click to expand.Just curious, did you have Jaz disks fail that had acceptable format and disk life ratings as indicated in the Tools program? The used disk that shipped with my drive now has a 100% format life and 99% disk life according to the program after I reinitialized it and then ran DiskWarrior on it.

I don't expect I'll be giving my Jaz drive yeoman's duty anyway, and this sure beats the hell out of digging through hundreds of floppies or even worse, no kind of backup at all with the files that are just too big to put on floppies. I suppose no kind of magnetic storage is 100% reliable and unfortunately I'm not currently set up to burn backup data on CD-ROM's on my system.

I mainly bought it just to free up some HD space after upgrading the system and get some non-essential stuff off the HD that I kind of hated to throw away. Click to expand.Dennis- I have the 2 GB Jazz. So far, one cartridge has failed mechanically. The metal gate jammed and now has a crease in it. Earlier I had problems when I attempted to reformat new cartridges using the longer method. As far as I can tell, a theft-prevention strip on the package is de-activated when you purchase the cartridge. The de-activation apparently involves a magnetic field that messes up the cartridge's format in such a way that the drive can't fix it.

I now have the store remove the theft-protection strip instead of deactivating it, and have had no further problems.
