I've encountered the problem with simple disks of <20 files, all type prg.
Perhaps someone with the ABACUS-published book on the 1541 can throw some
light on whether there is some readily identifiable state-of-the-disk and
characteristics-of-the-file under which overwrites may trash the disk so that
"@" mode can be used some of the time.

BTW, I have the ABACUS book with the C-64 ROM disassembly. It's worth the
price for the listing alone, although there do seem to be a fair number
of errors in the introductory chapters and examples. The ROM listings are
probably the only way to understand how the beastie really works.
Commenting is quite lucid except for a few areas where nearly totally omitted!
