Retreiving CD-ROM / DVD / hard drive information

I need to know the API's related to retreiving device information for CD-ROM, DVD, hard drives: Model, Type, Drive Letter, Manufacturer, etc. Also need a way to determine if a disc is a CD or DVD.

You will need to tap into several sources.  The GetVolumeInformation() API returns a lot of that.

Some other info is available by using DeviceIoControl( handle, IOCTL_STORAGE_GET_MEDIA_TYPES,...) after using the CreateFile() API to open a device handle.

The Model ID and manufactures and even the 'hardware serial namber' are easily available for WinNt, but not so easily accessible for Win9x.  Here is a link to an open Q in which we are exploring these issues:

Ok. I think I should clarify a point, tho. I simply need to populate a ComboBox with only DVD drives (i.e. G: - TOSHIBA XXX DVD-ROM). Currently, I use ASPI to retrive all the information I need, except to map the LUN to an actual drive letter. I was hoping the Win32 API would take of this so I could bypass ASPI.

The code from the EE will take care of the model/serial/drive letter, now I just need a method to determine if the device is a CD-ROM or DVD drive.

Use the GetDriveType() API.

this works for CD-ROM but not DVD. DVD and CD-ROM are both DRIVE_CDROM. I need a way to differentiate between the two so only DVD drives appear in the ComboBox;

Maybe you can use GetDiskFreeSpaceEx().  It retuesn the toal disk space (as well as the fre space). If it is > 700KB, it would maybe be a DVD,  I'll keep looking.

DeviceIoControl( hDrv, IOCTL_STORAGE_GET_MEDIA_TYPES_EX,...) looks promising.

i'll take a look at that know. it's part of DDK and didn't think to take a look.

i found it easier to query values in the registry to get the extended device information (manu, model, etc.). i decided to go this route instead. i was hoping the keys would contain a value to uniquely identify a dvd, but no such luck. Possibly can use DefaultDvdRegion, but kinda sloppy in my book :)

also, i need this to be determined even when media is not present in the drive, so checking size really isn't an option.
