Hi:
everybody, now i need to protect files on a removable (disk usb disk or
1394 disk ,etc…).
but i don’t know how to determine a disk is a removable disk or my local
disk that needn’t to be protected?
i want to use the deviceobject->devicetype, check it equals
FILE_DEVICE_MASS_STORAGE,right?

someone can give me help? think you!

No body knows?

IOCTL_STORAGE_QUERY_PROPERTY allows to find the of the bus (usb, SCSI, etc)
for a particular device.
