FALSE TO FACT. MSDOS/PCDOS had no _documented_ functions to directly access the disks, bypassing the file system, but the functions _did_ exist. The debugger's "read sector" and "write sector" commands used them, and I suspect chkdsk, scandisk, and format probably also used them although I never had occasion to verify one way or the other. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[email protected]"
