[net.micro.atari] 520ST disk write problems

clayton@bambi.UUCP (Richard V. Clayton) (01/31/86)

My 520ST is having trouble writing to floppies. For example, the TOS
formatter gets to the working box, but then the screen goes white and
the system crashes.  The system also crashes when creating and deleting
files, or when saving NEOChrome pictures.  However, Megaroids does
successfully write the high score file.

Write-protected floppies are recognized;  with protection removed, the
system crashes on retry.  After rebooting, I find the floppies are not
formatted. Files do get created and deleted, although the files are always
empty.

I have the standard issue 520ST system with color monitor.  The hardware
seems to be working ok; I can boot the system, list files, and run
programs.

Does anybody have any ideas about this problem and its fix?  My main
mail address is clayton%thumper@mouton.arpa

Thanks.
