cyclic redundancy

[tw]

There are so many issues involved in the CRC error that I am only going to touch on a few possibilities. Of course the most basic problem is diskette head alignment problems. Then a conflict using interrupts on the diskette controller since Windows 9x really did not use interrupts. Timing problems because floppies are expected to be ready to read data after a certain latency and those floppy drives are too slow. Timing problems that would only appear on how certain diskettes are formatted. Diskettes formatted by another machine - not from the factory. Such diskettes would not always format properly on all machines but may format on a few machines meaning the diskette is defective.

Information to collect - manufacturer of home and work diskette drives. Are any of these diskettes single sided? Will diskettes checkout using Scandisk at home after having been accessed at work? What does Chkdsk in XP say? Just a few ideas from a very long list of possibilities.
