Have you checked your prices on blank media yet? 1.44 Meg disks have twice the storage capacity, but about $80 for a box of 10, as opposed to $20 for 10 for normal 3.5 disks. +------------------------------------------------------------------+ | Michael J Pender Jr snail mail: Box 1942 c/o W.P.I. | | Bitnet: greyelf@wpi.bitnet 100 Institute Rd. | | Internet: greyelf@wpi.wpi.edu Worcester, Ma 01609 | | User #20 at H.U.G.E.

Depending on your nerve (and willingnes to back up what you really can't afford to lose) use the $20 disks (we do on our PS/2's all the time, and except for the 1 in 30 or 40 that refuses to format at the higher density, we haven't had any problems). Remember in the "old days" (5 or 6 years ago :-) using the reverse side of "single sided diskettes?" The only difference between the DD and the HD (besides the price of course) is the warranty (have you EVER sent a disk back and claimed a refund because the disk didn't meet warranty specs???? ;-) Murph Sewall Vaporware? ---> [Gary Larson returns 1/1/90] Prof. of Marketing Sewall@UConnVM.BITNET Business School sewall%uconnvm.bitnet@mitvma.mit.edu [INTERNET] U of Connecticut {psuvax1 or mcvax }!UCONNVM.BITNET!SEWALL [UUCP] -+- I don't speak for my employer, though I frequently wish that I could (subject to change without notice; void where prohibited) According to the American Facsimile Association, more than half the calls from Japan to the U.S. are fax calls.

First of all, a 1M disk formatted to the density of a 2M disk will fail much more often, so you had better keep good backups. Secondly, Apple's new 1.44M drive does not just blindly format a disk: it looks to see if there are one or two write-protect notches in the disk. If there are two (which you will notice is standard on a 2M disk) it will allow formatting as a 1.44M disk; if there is only one, it will only format it at 800K. The same type deal holds for MS-DOS 1.44M disks. If you try to insert a 720K disk formatted at 1.44M into an Apple SuperDrive to be read by Apple File Exchange, it will not work. Just a warning...

-for normal 3.5 disks.
The price will of course come down, just as it always has.

I'm surprised that no one has commented about the $20/10 disks statement. MEI has been offering 3.5" disks for .79 ea in lots of 25 for some time (some shipping charges are added, not much). If anyone wants to check them out, the number is 1-800-634-3478. If you order, you will get a flyer/catalog that lists exceptional prices for 5.25" disks, printer ribbons, etc. Usual disclaimer - not my dad, uncle, ... -- Joe Walters att!ihlpf!bird IHP 1F-240 (312) 416-5356

Have YOU checked media prices lately? The going rate for 1.44s is about $38, and 720s about $14. These were Sony disks, as I recall. The only place I see prices like the ones you state are office supply places, which traditionally charge far too much. ________________________________________________________________ Thomas C.

In this area I know a large number of people that use them. Totally, they have ordered thousands and none have ever commented to me about any sort of failure rate, abnormal or otherwise. Since I just got my first shipment of 3.5 and can't comment except to say that as of now I have copied data to 50 and have experienced no errors. In any case, the disks are warranted for life so if you should receive a bad batch, just call them and they will have you send them back. -- Joe Walters att!ihlpf!bird IHP 1F-240 (312) 416-5356

Generally, if I didn't have problems formatting the disks, I had problems reading/writing the disks after a period of time. (This was with both 3.5" and 5.25" disks.) BTW, I noticed that while you can generally use a good single-sided 5.25" disk as a double-sided disk, using a single-sided 3.5" disk as a double-sided disk doesn't work nearly as well.
