Hello, Netters!
I'm planning to replace the 20MB ST225 5-1/4" MFM hard disk mechanism
in my Megafile 20 with another Segate model (ST251-1, 42MB MFM)... I'd like
to continue to use Atari's hard disk software, but in order to format the
disk with HDX, I need to modify the WINCAP file so that it correctly represents
the new drive. Anyone know how to do such a thing?
If not, what software do you recommend I format it with?
Thanks,
Steve

Anyone know how to do such a thing? Could someone perhaps post what the meanings of all the entries are? I'm sure it would be of general interest to most users. Muchas gracias, entropy

Anyone know how to do such a thing? Yep. I replaced the drive mech in my Megafile 30 (RLL) with a 120Mb unit. Basically, all I did was pull the old drive out, plug the new one in and update the WINCAP file to reflect the new drive's specs. Then formatted it with HDX-3.01 (I think that's the version #) If you pull up the WINCAP file in a text editor, you'll see that it has comments inside it documenting how the different HD specific things are represented. It's really pretty easy provided you have all the technical info on your HD type sitting in front of you... From memory, here are some of the major things you'll need to know about the new mech: # of cylinders # of heads # of sectors per track Landing zone Pre-comp cylinder (Can't remember exactly if this is what it's called) Of course, I have a _sample_ home brew WINCAP entry at home... :^) -- /**************************************************************************/ /* Kent Dalton * EMail: Kent.Dalton@FtCollins.NCR.COM */ /* NCR Microelectronics * CIS: 72320,3306 */ /* 2001 Danfield Ct.

Swapping mechanisms is a very satisfying way to upgrade you HD space. I've got a 75 meg SH-204 myself :) (SH-204 w/ a Priam 75 MBy drive) Hardware-wise, all that must be done is to swich the drives. For editing the WINCAP file, most of the directions are in the file itself. The necessary information can usually be had by calling your drive's manufacturer's techicnal support department. If you don't want to do that, the Supra drive utilities also work, and have information for most common drives. -Tim

Some of the wincap parameters are nice normal parameters like number of heads, number of cylinders, etc., but some of 'em are weird: test pattern? (or something like that) It's different for many of the drives listed in the wincap, but I don't understand why. The ST225 that was originally in there uses the defaults for all of the parameters besides the weird test pattern thing. So far, I haven't received any e-mail responses, but if I do, I'll post a summary. > -Tim -- Steve Whitney "It's never _really_ the last minute" (())_-_(()) UCLA Comp. Sci. Grad.

The test pattern is used to test the drive for bad blocks (Physical Unit Markbad). These differ for RLL and MFM drives; the "worst" byte pattern - that is the one hardest to store for the media - should be used here, but it makes no big difference at all. hase -- Hartmut Semken, Lupsteiner Weg 67, 1000 Berlin 37 hase@netmbx.UUCP Hi!
