Tell me what you want, but these messages are being passed straight through from the FDC in your machine. (If you knew the NE765 status registers, you'd see the resemblance between these messages and the ST0/ST1/ST2/C/H/R/N result codes of this chip.) So either your floppy's dead, or your drive is worn out, or the FDC is using the wrong clock or such. I can ensure you that this is *not* a driver problem. You should also notice that most of your problems appear on sector 7 on both heads, which terribly looks like a scratch or fold in the floppy medium. You should finally remember that FreeBSD's floppy driver does not do a medium autodetection, so using a 720 KB floppy with the default (1440 KB) device would also result in a bunch of errors. However, this is not the case in your quoted example. All the error codes you gave us were ``Bad CRC in data field'', i. e. the ID fields were completely okay, and the data fields could be read, but failed checksumming. You might even have been returned the (bogus) data in the user buffer. -- 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. ;-)
