There continues to be concern on Windows, particularly where the media
isn't a hard disk but is something like a CD-ROM, floppy, or memory card
which has been formatted and duplicated by a program which ignores the
specification and intent of volume serial number and last write time, and
possibly file name.

It seems a shame to give up on equivalence testing because of such an
extreme corner case.

Any feedback about situations actually encountered by users will be



PS: Other operating systems besides Windows may have similar issues; volume
serial numbers (or equivalent) were common on batch processing systems that
had to cope with a large number of mounts per second (due to automated tape
library systems.)
