I wish. 8kb/s is what dd reports for my floppy drive. No surprise. One of the problems probably resulting out of the abuse of buffered devices. 40 KB/s is exaggerating, but 30 KB/s is the raw sequential throughput the FreeBSD driver does. That's about 67 % of the theoretical maximum (45 KB/s). > Oh, and regarding the fdformat in another post in the same thread: when > FreeBSD finds an error on one of my floppies, it's dead.

Boys, you should at least learn the very basics of floppies, and the floppy controller used in PeeCees (NE 765 aka. i8272, really a very sick device from the early 80's), before you're starting to speculate what could be done in a driver. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
