It starts out with no partitions and claims the partition table is not a valid P112 table. The "w" command fixes that but the table is still empty. Interestingly enough, a 64M CF in an IDE adapter works with FDISK. but then when I try to "INIT" it under RSX180 it prints a stream of garbage on the screen and does nothing to the disk/CF. Not sure how much longer I am likely to keep beating my head against the wall. bill
