How to differentiate a local disk driver from a removable disk driver in filemon

NTFSD
1

in filemon I want to determine the logical driver is a local disk driver
or a removable disk driver.
use getdrivertype() function they all returns DRIVE_FIXED,

and in filemon.c,I use the clause

if(fileSysDevice->Characteristics & FILE_REMOVABLE_MEDIA ){

DbgPrint((“this device is removiable”));
}

it never print anything,

does exist any method to differentiate them?
thanks.

hi.
first,you should verify that the filemon has hooked the FILE_REMOVABLE_MEDIA ;
second,you should make the FILE_REMOVABLE_MEDIA working before the filemon is running,
good luck!

Note that many USB flash drives are NOT considered to be removable media.
