how is hotswappable different to other types? Have you actually run fdisk and attempted to create a partition? Was there a problem?

The user puts the CF-card into the device and the software should copy some data on it. Therefore the CF card needs to be partitioned and formatted with a filesystem. Formatting is no problem, but I have no idea, how to create/change partitions from my program.

The CFDISK will have a device file name e.g. /dev/sda

# fdisk /dev/sda

Then follow the menu system to create/modify/delete partitions
