Please contact Richard Frick or John Feagans, at Atari, or Robert Katz, at Atari in Britain, for a new hard disk driver. You *need* it.

Talk to DRI.... :-) > Why has this happened at 20 and not 40 subdirectories? The number is small and arbitrary. 20 is about the limit -- actually, I suggest 16 or so. This covers *all* directories on the hard disk. > Why is 40 a limitation anyway? The DOS that DRI wrote uses a form of static allocation. It permanently allocates structures that describe the disk hierarchy; if you have a lot of directories, GEMDOS runs out of memory -- with potentially disasterous results. > Is this a known problem? Yes. The production 20-Megabyte hard disk driver will alleviate the problem somewhat. Atari is working on a more permanent solution (actually, a couple different ones). > Have I really got to have huge directories? Yup. 16 of them, until you get the new driver. Then it's 40 or 50. > Please! You're welcome. (You think we /like/ this kind of problem?) -- Landon Dyer "If Business is War, then I'm a Prisoner of Business!" Atari Corp. "Gee, 20 mushrooms?

The problem is one of memory, your version of AHDI doesn't allocate enough memory for more than twenty subdirectories. A new version of AHDI has been available for a few months that solves this problem, contact ATARI-UK for a copy. If they don't have it, its available on the ATARIDEV section of compuserve, but you need to be an authorized developer to download it This should do it Neal 'NAK' Katz #include <I.dont.know.nothing.h> > > Nigel Roles > Department of Computer Science > University of York > > ..!ukc!minster!nigel

There is a new version of the hard disk driver (ahdi.prg) that is in the auto folder, which relieves some of these problems. It may be downloaded from CompuServe (ataridev) or your favorite BBS. If you have any problem getting a hold of it, i can mail you a uuencoded version. Jwahar R.

It has been posted to the Atari Developers SIG on CompuServe. Check with the developer support person at your closest Atari office if you're not on CompuServe. --->Neil @ Atari UUCP: ...lll-crg!vecpyr!atari!neil
