Well, here is the summary of responses with the original question at the top. I think I'm going to get the Mass Micro unit. Anyone have a good (big discount) place to buy this unit. - How about a good source for the cartridges? - Thanks again...

Organization: University of Michigan, Ann Arbor I like my Mass Micro Data Pak, I have a single drive but think I should have bought the twin pack. Aside from that and the fact that the spindle motor went west in less than a month on the first unit we got, I would recommend the drive highly. Formatting is very slow but the cartridges come pre formatted so this is only a problem if you reformat to get rid of bad blocks which was necessay in one of the 8 cartridges I bought. Partition software crashes the mac on a MacII with system 6.0.2 and I have not received a satisfactory response from Mass Micro on that yet. Doesnt work with A/UX. In spite of the seeming negative comments Iwould recommend the drive. -- John Mansfield, North Campus Electron Microbeam Analysis Laboratory, 2455 Hayward, Ann Arbor, Michigan 48109-2143.

Friends recommended the MassMicro DataPak to me and that's what I bought. It has worked great so far (a couple of months), but I've only filled two cartridges so far.

Texas CS Dept., Austin, Texas I have been using a MassMicro DataPak for more than three months now. I am more than staisfies with price and quality. It is convenient, fast and reliable. I bought mine from Don Mayer (800) 541-2318. His company is called Brain Warez, and he has very good prices. Also, Mass Micro gives educational discounts to Universities.

The first one corrupted two cartridges so badly that they could not even be reformatted. The second drive would build up errors over time. That is, I would be using the drive and a file would become unreadable. If the Data-Pak Utility's test disk option was run it would show errors. The number of errors would continually increase over time. If the disk was reformatted, it would show no errors, but they would agian build up over time. The timeframe involved was about a week between reformats. Since I wanted to use the drive as a backup device and an alternate drive, these errors were unacceptable. The technology seems a little too unstable for my use. It may have been the environment in which they were being used, an non-air-condtioned office in the Virgin Islands (average temp 80 deg.F) that had open windows. It was, however, well within the published operating specs for the device. It may work perfectly well in the normal air-filtered and temperature controlled environment that most offices maintain.

The unit is a Syquest SQ555 drive (same as the one mass micro sells [they are manufactured by syquest]). I've been using it now for about a month now as my main drive and have had no problems. The other important factor involved with the drive is the software driver. The one I'm using with the device is by Software Architects and works well. It can handle cartridge changes properly. This is important if you need to swap them without restarting. Michael Veldman Product Evaluation Engineer Adaptive Pty Ltd Melb.

One example is the Bernoulli Box, which gives 20 meg per disk and uses 5 1/4 floppy media. It's fairly fast, and if you just write the backup and don't use the disk again, it's reliable. BUT if you use it as an alternative hard disk, you will be screwed, because the disks become unusable after about six months' constant use. Alternately there are the removable-disk hard disks mentioned above. Another is the removable-drive Passport Plus from the people who brought us the Hard Card (a PC product, and I forget the company name.) The difference between these two is, in the first you remove the hard disk platters, and in the second you remove the platters and read/write heads both. (I had my only PassPort fail on me; I don't recommend it very highly.) If you don't want these options, then there are 80-meg-per-tape backup drives from Irwin and a few others. I think the Irwin is reliable, as long as you ONLY USE 3M or IRWIN tapes. Obviously, this method won't work as an alternate drive; it's s-l-o-w, and most tapes won't even mount on the Mac desktop (you have to use the backup software to access the tapes). And if you don't like these so far, then you can go with optical, or floptical. Optical is like 400 meg per WORM disk, and of modest speed; floptical is actually a hybrid that uses magnetic data storage and optical servo head positioning on a floppy medium. Floptical is NOT yet available, I believe. Personally, I like to use a succession of cheap Jasmine 20 meg drives as my replaceable disks... but then, I'm not at all well... -- Thomas "Wombat" Cox I have two hit points left, and we're winning anyway?
