Disk drive letter assignment

Hi, i have a question about disk drive letter assignments.

If i call IoCreateSymbolicLink in my device driver to assign a
drive letter to the disks i create, how will that change the
overall drive-letter assignment scheme used by the Disk Administrator?

Thanks in advance.

You don’t want to do this yourself. You expose these devices using the pnp
interface mechanism (IoRegisterDeviceInterface
(…,MOUNTDEV_MOUNTED_DEVICE_GUID…). The mountmgr will then try to assign a
drive letter for you. Read the section “Supporting Mount Manager Requests in
a Storage Class Driver” in the DDK.
