Partitioning Media
If a Compact Flash or USB device is formatted with more than one partition, only the first partition
will be visible / available to the CFFA3000. All others will be untouched.
Compact Flash Cards
If you want old-style CFFA functionality - hard-coded drive partitions - your Compact Flash card will
need to be zeroed out, or reformatted so that it doesn‘t have a Master Boot Record (MBR) at all. You
can use tools like Disk Utility (Mac) or the CFFA3000 firmware to do that. See Figure 6 for an
example.
