It sounds like part of the special hybrid iso+HD image format from the Debian image remains on the disk. Generally it's best to dd zeros over the start of a drive before reusing it, especially with a special format like that. What I would do in this situation is copy the data off, "dd if=/dev/zero of=/dev/rsdXc bs=1m count=1" (replace X with the correct device number), repartition and reformat, then copy the data back. I wouldn't recommend ext2fs, it's not very widely used so you're more likely to run into a problem. Likewise I wouldn't use FFS support on Linux for the same reason. FAT32 is a safer choice if you need to share the filesystem. > 2.

Try raising the datasize limit, either try "ulimit -d $((2048*1024))" before running firefox, or raise datasize-cur in the 'staff' class in /etc/login.conf and logout and back in.

But reply to the list with output of mixerctl, audioctl and dmesg (inline, not attached) and see if someone else has an idea.
