[mkgmap-dev] somewhat OT: garmin oregon disklabel?

From Jeroen Muris jeroen at tweejee.net on Tue Aug 31 13:53:05 BST 2010

My Oregon 550T shows two FAT32 formatted disks in Windows 7 and XP, and
from memory (lost the Mac and the Slackware laptop) I could read/write
these in both OS X and linux.

Maybe your OS lacks a driver for FAT32?
