Aha! 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. Right now.

Tee hee. 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?)
