changes in 10.213:
USBMSD:
1) again reworking geometry computation, simplify code
2) adding EXFAT support for large floppy formatted media: this is done in anticipation that someone will write an EXFAT IFS for OS/2 large floppy EXFAT formatted media will then be virtualized as partitioned media in the same way as it is done already for FAT32 large floppy formatted media
3) reworking device detach
4) compute a GUID for virtualized floppies that only depends on device characteristics and that will therefore be identical on each device insertion of a particular device: this was done to prevent a trap 3 in OS2LVM where OS2LVM will try to rediscover a partition via its unique partition serial number which can lead to problems if a device is just ripped out without being properly ejected first. The so computed GUID will now be used as the disk/volume/partition unique serial number
changes in 10.212:
USBMSD:
1) fix a bug in geometry computation that would lead to a division by zero trap on ejecting a device, leaving the device inserted and then doing a "rediscover prm"
