information is also in the win32api that comes with most compilers, and can be found relatively easily with google - its size varies from 12mb upwards, and is also included in some of the microsoft sdk's etc..
Searching for 'GetDriveType' might have also helped, most win32 api's have an A at the end (signifying Ansi 'version' of the code) or a W (signifying unicode/widechar 'version' of the code)
The GetDriveType function determines whether a disk drive is a removable, fixed, CD-ROM, RAM disk, or network drive.
UINT GetDriveType(
LPCTSTR lpRootPathName // address of root path
);
Parameters
lpRootPathName
Points to a null-terminated string that specifies the root directory of the disk to return information about. If lpRootPathName is NULL, the function uses the root of the current directory.
Return Values
The return value specifies the type of drive. It can be one of the following values:
Value Meaning
0 The drive type cannot be determined.
1 The root directory does not exist.
DRIVE_REMOVABLE The drive can be removed from the drive.
DRIVE_FIXED The disk cannot be removed from the drive.
DRIVE_REMOTE The drive is a remote (network) drive.
DRIVE_CDROM The drive is a CD-ROM drive.
DRIVE_RAMDISK The drive is a RAM disk.
the DRIVE_* are equates.. and its really 0,1,2,3,4,5,6 (5 being cdrom, dvd is also 'cdrom')
hope that helps, happy googling
