I've been having difficulty making boot disks(floppy
images) with dd. 

FreeBSD 4.5-RELEASE i386

su-2.05a# dd if=color.gz of=/dev/fd0
dd: /dev/fd0: Invalid argument
2605+1 records in
2605+0 records out
1333760 bytes transferred in 41.431344 secs (32192
bytes/sec)


Linux 2.4.18 i686

[emmanuel@gimpy rootdsks]$ dd if=color.gz of=/dev/fd0
2605+1 records in
2605+1 records out

Some of the records are not copied. It's not a
permissions problem because I was able to write onther
images. The color.gz is small enough to fit on a
floppy (it works on Linux). I thought it might be my
floppy drive or disk but someone else was able to
replicate the problem...

The problem is not so much not being able to make the
slackware boot floppy, the problem is not being able
to consistantly make floppy images. Any ideas?
