Hi Malcolm,
thanks for your answer!
We use Sundisk Compact-Flashs, too.
How can i get the version number of a sundisk flashdisk?
On the Front Side i only have the size of the disk and the name SunDisk
CompactFlash
On the backside I have a PAT Number.
Perhaps you can say how i get the version number, i try to get
the information from our distributor,too.
Thanks
Clemens
