Hi all,
My driver is a disk upperfilter driver. How can I transfer a device name such as \Device\HarddiskVolume1 to a volume name such as ??\E:?

Thanks & regards.

Do a recursive call of “ZwOpenSymbolicLinkObject” on every driver letter and
compare the result with the device name you want to map

Thanks.

Can I get a name like \Device\Harddisk0\Partition1 or \Device\HarddiskVolume1 in AddDevice dispatch? Is there such APIs?
