How can I find the capacities of a disk drive in Window95/8?

DeviceIoControl (IOCTL_DISK_GET_DRIVE_GEOMETRY) for Win95 is what I'm looking for but it's only for NT.

I've used some of the DeviceIoControl's operations using an example which uses VWin32 to call Int21h function FF0Dh subfunctions but cant't find the subfunction for getting the drive geometry as performed by by DeviceIoControl.

What I am trying to do is find out what drives contain high capacity removable media.

Any help, especially a book title, greatly appreciated.

Thanks in advance,
Fred

One size never fits all.
