How to load the Index Number of Drives (the Uninitialized and Initialized Drives)

[hoangdiemtinh]

I am newbie, from Viet Nam. Sorry for my bad English.

I am trying load information of Drives (Index + Name + Total Size + Total Partitions) to the ComboBox Gadget, like the picture
.

.
(HD = Hard Disk, RM = Removable = USB FLash, Card Reader)
.
An Uninitialized Drive is no have Letter Drive. Only can get information its via the Index Number of it.
.
But I dont know how to read the Index Drive of the Uninitialized Drive (as this: viewtopic.php?t=80153)
Someone please help me (Prefer WinAPI, then maybe WMI).

Thanks.
