4.6 Formatting a CompactFlash Card
C
WARNING – Formatting a CompactFlash card while it is in the receiver
deletes all the data files on the card and all the application files in the
receiver.
To format a CompactFlash card for use in a Trimble R7 receiver, insert
the card in the CompactFlash port and then hold down [P] for at least
30 seconds. After 15 seconds, the receiver is reset to its factory defaults,
and any ephemeris file is deleted. After 30 seconds, any files stored on
the card are deleted and the CompactFlash card is reformatted.
Note – When you use [P] to format the CompactFlash card, a quick format
is performed. A quick format reformats the card for use with the
Trimble R7 receiver receiver and deletes all data on the card. A full format
checks the card for errors or bad sectors, and is only necessary if the card
is corrupted. To perform a full format, use the GPS Configurator software.
For more information, see The GPS Configurator Software, page 68.
