Hi,
I need to control access to removable media (floppies, USB Flash disks, CD).
It can be done easily in Windows 2K/XP by applying DACL (discretionary access control list) to the volume with API function SetFileSecurity (or SetNamedSecurityInfo). Volume name is specified in the form \\.\X:
But in Vista this approach does not work for USB Flash (while with floppies and CD all is OK). DACL is still applied to the volume (it can be read with GetFileSecurity function), but it has no effect on the access: users, that are not enumerated in the DACL, still have full access to the flash.

Any help is appreciated.
Thanks.
