Craig – Basically, they're fine. They are not real fast, but they're as fast as a reasonable hard drive was two years ago. One thing to bear in mind, though, is that they do go bad, just like floppies can. We use them to move massive files to service bureaus and the like, but not for permanent storage of "mission critical" items. Generally, when one craps out, Norton utilities or another like it can resurrect the disk and data. I've only had one die outright. On the other, other hand, once you get the drive, the cartridges are dirt cheap (about $70/40 MB). At that cost, you could probably use two containing the same data for the archiving purpose and not have to worry at all. Plus, they don't die that often, any more than floppies do. Now, with all of that said, let it be known that none of our PC sport one of these, only our Macs. When they go bad, it tends to be loss of SCSI driver or Vol Info Block data, so the disk won't mount or can't tell where anything is on itself. These kinds of errors I consider to be sympomatic of the Mac OS which, as I MENtioned to that Wayne guy, is the most unstable out there. Hope that helps a bit. Find a money-back guarantee and give it a whirl….For archiving, I use ArcServe running on MicroNet 5 GB DAT tapes. The access time is about 20+ seconds for finding a particular file. Not bad, considering it's tape. David Taffet

David: Yeah… that's pretty good. I used Colorado Memory before and the access time from tape load was about 6 minutes… and then about .2 seconds once the tape directory was read… Drives you nuts if you don't know what is on the tape, plus you have to keep adding volumes of the same stuff instead of updating the single volume. Soo…. we ended up with a 'flying' tape and then an 'archive' when we 'thought' the project was finished <Grin>. I'm interested in this because I will create a disk, or two, for each project and keep updating the files. When I'm done with a certain stage of the project that I would like to keep for archive purposes, then I will just get another disk. You don't think this is a good idea because the media isn't stable enough, I gather? C#

No, I wouldn't go so far as to say I think the media is not stable enough. It's really at least as good as floppies. Plus the storage capacity is obviously great. Another benefit is in transporting files to service bureaus. I just wanted to let you know (you probably already did) that the media is not fail safe. A couple of copies is still a good idea. Regarding your old tape system, ArcServe and a Mac program we also use for interim drive clearing both are able to do incremental backups, meaning they only back up files that have changed since the last backup. They also keep a log file of what is on each tape, in each session. Palindrome, another DAT system (proprietary, tho' and costing around $5000) will even label each of your tapes, migrate files off your drive that have not changed in X amount of time and tell you which tape to insert to get the file you call for restoring. Now, to throw another wrinkle in, for about 2 times the money you could get a 3 1/2" optical drive that holds 128 MB per $30 disk and, being optical, has a shelf life of about 10 years. You could put them up on your refridgerator with cute little magnets and they'd still be good. Back to the Syquests (hop here, hop there), as I said, we only use them on Macs, so the stability on a DOS system is an unknown to me. I'd guess it to be much better, as with the operating systems themselves. So, I haven't said "Yes" or "No", so that makes me a real expert, right <g>. Let me know what you decide…… DT

David: Thanks. I've often wondered about optical drives… maybe I should just get a CD writer… Sony's coming out with one… C <Money money money money… MONEY> #

I hadn't heard about this. You mean really, like, CD's? Not rewritable opticals? How many arms and legs is this thing gonna cost? DT <Money, money….is that Pink Floyd or the Grateful Dead?><g>

David: I, um… wanna say $14k, but I'm not sure… G knows, I think. C#
