Well, I'm at an impasse with this silly drive, and am asking for any help... What I have: 1) A working 20Mb Supra drive with an internal Rodime SCSI drive. 2) A bare 20Mb drive that I hope to soon have working as a secondary drive. 3) An ADAPTEC 4070 SCSI to RLL controller. What I've tried: 1) I have replaced the 50-conductor internal SCSI cable in the Supra drive with a cable similar but with yet another 50-pin SCSI connector which attached to the ADAPTEC 4070. 2) 20-pin and 34-pin cables between the ADAPTEC 4070 and the new drive. 3) The Adaptec 4070 has been selected as SCSI ID #1. The symptoms: 1) When the SCSI cable to the ADAPTEC controller is disconnected, the Supra drive works fine. 2) When the SCSI cable to the ADAPTEC controller is connected, the BUSY light on the Supra remains lit, and the Supra will not spin up or function at all. The second drive will not spin up or function either. I recently saw an article in the ASTUN newsletter that was written by someone at Supra, regarding attaching additional drives to their controllers. Unfortunately, I can't seem to lay my hands on that now. Any suggestions or hints would be greatly appreciated. Myron Drapal AT&T Denver, Co. ..!ihnp4!drutx!druhi!med

An even easier method is to use a program like Desk Manager or Superboot which allows you to select your desk accessories and AUTO programs. Just make sure that Desk Manager is the very first file in the AUTO folder and that way it will always load before the crashing TSR or accessory. Then you just nuke it after the first time it bombs. Another way to do it, if you're a masochist, is to stick a command line interpreter in the AUTO folder so you can rename the files manually. - Darek ------------------------------------------------------------------------------ Darek Mihocka ST Xformer II CIS: 73657,2714 Box 2624, Station B Quick Utilities GEnie: DAREKM Kitchener, Ontario MegaBlit SSG SPX DELPHI: DAREKM N2H 6N2 Shareware, not Vaporware BIX: darekm Canada Amiga 3000 has a 68030!

Clusters 0 and 1 are either marked as 0x0000 or 0xFFF7 depending on your controller and are not available for data. They are not used because they don't really exist on the disk. Their presence is a holdover from the orignal development of the FAT system on DOS machines. >3) Is it posible that a poorly behaved program allocates these two non existing data clusters, thinking that they are free? Not unless they bypass the OS and program the HDC and DMA to read and write physical sectors. If they do this and screw it up, then you can have problems. ____________________________________________________________________________ Bob Luneski Diamond Back Support Hotline: bluneski@pogo.WV.TEK.COM Genie: B.LUNESKI1 The opinions expressed herein are my own and in no way reflect the opinions of Tektronix, Inc.

[this a a reposted repost - we just went Internet and have been having News problems] My hard disk had a nasty shock last week during a rather heavy bout with static electricity. It recovered after I turned it off and back on but now it seems to be flaky. While running minix it made some funny noises and seemed to slow down. I had to reboot (but I haven't tried to shut it off and back on yet.....). (I wrote the above a couple days ago... but we were having News problems so it didn't appear to get posted to the outside world. My sincerest apologees to anyone who might have seen it before.... My hard drive has since continued to behave in such an erratic manner as described above except I don't have to reboot , just have to wait for it to start behaving itself again. But it isn't consistent. (My current theory is that how it behaves depends on the quality of power getting to the hard drive ..... could nbe wrong but it sounds good :-)) I had planned to do some serious hacking with Minix this semester (to teach myself enough to write an application in C that I want to be portable between Minix, Un*x, MiNT and TOS/GEM (TOS/GEM being last since I've got what is quickly becoming an antique [even for an ST], a 1040STf with TOS 1.0 (6 chip ROMs, empty board space for a blitter, etc) and by the time I get this program done I'll be able to afford a TT ...)). But I haven't gone near Minix since the first drive problems since it had problems with that since Minix almost continually accesses the harddrive and if it's not there..... **BOOM** (* Can you tell I've got a degree in English lit. from the rather convoluted paragraph above... %-> ??*) Does anybody know of a utility program that could check the controller on my harddrive to see if it is ok ??? It's a 30 meg Supra harddrive, approximately 3 years old (one of the ones with the bad clock chip and a SCSI port (How do I test something like that ?? ARGH!!!!!!). I really can't afford to have it die, but if it does I'd like to know why and what I should replace (if I can.... ) -Andy- Send all complaints about the wordiness of this article to the Grammar Police.
