My ST has been doing some very strange things lately. It used to
be that when I swapped disks (internal 1040STf drive) and hit "ESC",
the GEM file window would show the new disk's files. Lately,
though, it's been flakey. It might show _some_ of the new disk's
files (i.e., 25 out of 70), or it might show some of the new disk's
files alphabetically sorted with some of the old disk's files, or
it might work normally.
At first I suspected fried media, but I eliminated that by trial
and error. It popped up when I first tried formatting a disk with
DCFMTCLR (DC Formatter) with an IBM boot block (so I could move
text to the NEC Multispeed), but it later happened with Fixed Twister
disks. The workarounds involve sticking in a third disk (with ROM
formatting?) or using the close box and reopening via the icon.
A particularly weird one happened when I was copying bunches of
files at a time (via the RAMdisk) from an NEC-formatted MS-DOS disk
to a DCformatted disk. The new disk didn't show the files at all
after I completed the copy job, so I started again. The next day
I turned the Atari back on, looked at the disk, and found DUPLICATES
of the files which I had copied twice -- the missing stuff reappeared
and the recopy of 15 files (of the 70) was still there too! BTW
the "free space" was rather random too, and a number of times the
MS-DOS disk showed fried-disk symptoms like garbage files popping
up on top of the disk. Also the MS-DOS label came out as a zero-length
file on the Atari.
What gives?

It happened only once when I was copying files from a ram disk to an IBM disk. As you pointed out, this seems to happen only with IBM formatted disks. I suspect that the problem is copying files to IBM sub-directories. As pointed out before on the net, this causes a problem with the minor differences between the two formats. My friend attributed the problem to the 40 folder bug, but I don't know enough about it to tell. If you do any disk swapping between IBM's (including PC-ditto) and the ST, use the root directory only. It seems to be the most reliable way to do it. Hope this helps, and I hope others can elaborate my discription. -Vitas P.-

I have not seen it show "_some_ of the new disk's files". It is more like it being unaware that a disk has been removed and another one put in. I suspected a dirty contact somewhere in the drive. -- L. J.

Here (ARCed and uuencoded) is a program that formats floppy disks so that
they are ABSOLUTELY 200% COMPATIBLE with MS-DOS. It lets you choose
between formatting a 3.5" disk in drive A: (720K, MS-DOS 3.3 format) or
formatting a 5.25" disk in drive B: (360K, MS-DOS 2.0 format). The disks
can be read and written by both the Atari ST and an IBM-PC compatible.
Subdirectories are no problem.

Another guess: you are using disks with the same serial number. The result is that the operating system is confused and doesn't know what to do. Use Diskdoctor or SECED to check (I believe) bytes 7,8,9 of the boot sector of your disks (where the serial number is). If those bytes are zero or the same value over several disks then you must change them. This problem shows up from time to time because the early version of twister did not set serial numbers ramdomly.

I observed such behaviour a couple months ago. I: (a) stopped using scache; and (b) got a drive-cleaning kit and cleaned the drives and the problem went away. Being a lazy sod, I haven't investigated since to see if (a) had anything to do with it. I suspect (b) is sufficient both because I trust Moshe's code and because no-one else seems to have noticed problems with scache. (Haven't bothered to put SCACHE back because it doesn't seem to work with my DS disks, only with SS, and having come up in the world I don't use many SS disks any more.)

Summary:Test message This is a test of our posting program to the Atari ST news group, if this message does happen to make it out could someone please respond. Once I have the program running properly I will be posting some machine source code for use with Assempro, also will include sources showing how to use some of the Line-A commands. ble.$Cessary
