Hi Guys, after some time tackling with this problems I think found the root cause and solution. (at least in my case)

Problem seems to appear when CF disk is formatted in windows operating system, to fix this you can use diskpart util.

To do that start "Command prompt" as "Administrator" and do following. Note in my case CF card was disk 3.

WARNING MAKE SURE YOU SELECT RIGHT DISK AS EVERYTHING IS GOING TO BE WIPED OFF..

DISKPART> list disk

Disk ###  Status         Size     Free     Dyn  Gpt
 –------  -------------  -------  -------  ---  ---
 Disk 0    Online          119 GB      0 B

 Disk 2    Online          931 GB      0 B
 Disk 3    Online         3815 MB      0 B

DISKPART> select disk 3

Disk 3 is now the selected disk.

DISKPART> clean

DiskPart succeeded in cleaning the disk.

and now you should be able to write to the CF card
