Reformatting the PC Card

PC cards are normally pre-formatted. If the card is not pre-formatted, it may be
formatted through a PCMCIA drive in the PC, using the DOS format command. In
addition, prior to initial use in the receiver, the PC card must be reformatted inside
the receiver using the $PASHS,CLM (clear external memory) command. This
allows the receiver to optimally format the card using a special File Allocation Table
(FAT) algorithm. PC cards should also be reformatted regularly (bi-weekly for
receivers in constant use) inside the receiver to ensure minimum fragmentation of
the card.
The receiver can reformat the card using one of two methods:
• Via the serial command $PASHS,CLM, which formats all tracks in the
card. This includes the FAT area, directory area, and data area. This
