No problem....  Try this...

dd if=/dev/at0 of=/usr/tmp/disk.image bs=1024 count=1200

if= and of= were missing.

Also, make sure you have /dev/at0 there, and that it is the same as /dev/fd0.  I have had similar problems on SCO, but realized that I was using the "wrong" device (major, minor number).  Technically speaking, the bs and count aren't necessary...
