[net.micro] Weird bug on IBM-PCs

DRW@mit-mc (Dale Worley) (02/23/85)

This software system I've worked on writes long files on the floppies
of an IBM PC.  Some of our customers, very rarely, discover that large
sections of the files have been replaced by many, many blocks
containing nothing but the byte 246 (decimal), or (rarely) some other
value.  I'd suspect the application software (it contains a simple
database manager), but it isn't the sort of symptom that I'd expect,
given how the code works.  Thus, I'm led to expect that the real
problem is buried in the guts of IBM Compiled Basic, or MS-DOS, or the
hardware of the PC.  Has anyone witnessed a similar bug?

Thanks,

Dale
