Format disk
Selecting “Format disk” will erase the CF-card in the P+ back. The CF-
card will be formatted as FAT-32.
Please see CF-card section for troubleshooting if your card is not
recognized.
Disk Checking
Disk Checking is done per default on every card inserted to the P+ back.
If for some reason this check is not wanted the feature can be turned
off in this menu.
Phase One recommends leaving diskchecking turned on, to maximize
data security on memory cards.
