[comp.virus] Does write-protection work?

USERASSJ@LNCC.BITNET (Alberto Sulaiman Sade Junior) (05/30/90)

SOME TIMES AGO I READ THAT IS POSSIGLE A VIRUS INFECT A DISKETTE
PHISICALLY PROTECTED.  I KNOW IT IS AN OLD DISCUSSION BUT IS IT REALLY
POSSIBLE ?

[Ed. Yes, this discussion has come up a few times before.  After much
heated discussion, the consensus was that (on a PC), the write
protection is implemented by hardware in the floppy disk drive
(according to the IBM Tech. Ref. schematics).  At least in the case of
PCs, I urge us to consider this matter closed unless someone can come
up with conclusive proof to the contrary (i.e., send me a piece of
source code that proves it).]
