#script to do simple backup on Psion LX

#Notes: hda could be CF slot or PCMCIA slot. 
#If one is filled and second added then that's hdc
#1st USB device is sda, next sdb and so on.
#This script cannot know if hda is in CF slot or PCMCIA slot.
#Best thing for itto do is probably use whatever card is present if there is only one:
#If there is more than one, ask user which to use, glossing over CF/PCMCIA prob
#OO upgrade may mean CF card is often present butnot to be used for backup. 
#Could give them all a recognisable ID so they can be auto-ignored.
