I've seen several problem reports, but can only reproduce a very small percentage of this (and only by pushing hard and ejecting/reinserting floppies while IO is in progress). Make sure to _not_ use the buffered device for streaming IO, i.e. the only reason to use /dev/fd0 is to mount a filesystem, you should use /dev/rfd0 for _everything else_. This might work around some races as well, but there are many good other reasons for doing this way. -- 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. ;-)
