The floppy ROOT directory has 112 entries in it.  Each can, of course, be
a directory.  Each of these is limited by the number of fat entries, which
is to say the storage on the disk.  A 720 K disk has about 720 clusters
and if you assigned 700 directories (no files) you would surely fill it
up.
I suspect its the 112 limit that you are confronting.

This is a repost, since no one answered it before:
 
Where can I get G-Dos?  I have never seen it anywhere.
 
Simple question, someone MUST know the answer.

1. It is not clear if its you or Supra that has a problem.
2. If you;  Minix 1.1, as shipped expects to find a minix root partition
   at partition 2.
"
  /* Get size of RAM disk by reading root file system's super block.
   * First read block 0 from the floppy.  If this is a valid file system, use
   * it as the root image, otherwise try the hard disk (RAM_IMAGE).
   */
#ifdef ATARI_ST
  printf("Booting MINIX-ST 1.1.  Copyright 1988 Prentice-Hall, Inc.\n");
  printf("Insert ROOT diskette and hit RETURN (or specify bootdev) %c", 0);
  root_device = (dev_nr)getdev();
  if (root_device == 0)
#endif
"
So, It is assumed that you first boot MINIX from a floppy.  At this point
you can prepare a partion, 2 being preferred for minix.
 
3. You can test if you have basic communication with the HD, from MINIX,
by reading section 0, which is the boot sector, and partition 1, which is
(I assume) TOS.
        dd if=/dev/rhd0 > /tmp/hd0  should not fail.
        tos -d /dev/hd1 should print familiar information on TOS c:.
If either or both FAIL, then you have INTERRUPT problems.
 
4. Remember TOS is polled IO, not INTERRUPT.  You would never no if disk
interrupts failed under TOS.  MINIX only uses INTERRUPTS.  Assuming that
the 1040 is  not bad (Try someone elses HD); its a Supra problem.
 
5. Supra had three vintages of Atari interfaces.  OLD (Never would run MINIX),
    Medium (could run minix with a Supra supplied software change), and NEW
   (as in with fan, and DMA OUT connector) that did work.

I am sorry I had to post this to the net.  My mailer would not let me send
mail to you (probably would have worked if I had REPLIED to you before I
deleted the message!).  I am most interested in your offer concerning the
hard drive.  Very most interested.  Positively giddy.  Anyway, please
reply to me directly if you see this, so I know it worked (and so I can
reply to the mail).

If you could make it less disruptive to other programs, we would really have
something!  This is the best looking screen saver I have seen for the ST, but
it is not tolerated by many good programs.  Someone please fix it!

Subject: Telefax by modem use
 
Dear netters,
I would like to use my Mega 2 (60 Mb harddisk) for sending and receiving
telefaxes via the telephone modem. Does anybody have experience in this topic
or/and knows any programs for that purpose?
Ciao, Thomas.

Subject: Terminal emulator DA
 
Recently, Wayne Ngai and Rens Troost asked for a terminal emulator. This
is my favourite: MINITERM, by Lars-Erik 0sterud. VT-100, IBM-graphics,
X-Y-Z Modem, ASCII upload, log file, phone dir and the lot, for FREE.
It works as PRG and ACC. Available from panarthea.
Try to get version 9.32, I got it from Lars-Erik's ABK-BBS in Norway:
+47 2 132659.

Subject: TT and STe info needed
 
I will try to be brief but I have some burning questions.  I have been Atari
fan since first computer...I have owned several 8-bit's...I have also been
fan of ST for as long as there has been one.  I regret that the computer has
not been supported in America as it should.  However, I am still planning on
buying one.  This brings me to my questions.  SHOULD I WAIT FOR THE NEW
ATARI STe AND TT?  AND WHAT EXACTLY ARE THEY?.  It is hard to get that kind
of info here.  I hate asking people if they sell Atari Computers and have the
reply "Atari still makes computers?."  Please do not send hostile replies
I am truly an Atari fan (till death).  And I hope sincerely that these new
computers will sell in America.  As for those of you who ask, I am a comp.
sci. major at West Virginia University and want the computer for programming
and telecommunicating.  Please send replies directly to me as not to take
up space on the list.
                                                  Sincerely,
