Well, to get you started, I think this is the kind
of thing you'll want. Uses ctypes, which is built-in
to Python 2.5 so presumably legit.

<code>
import ctypes
import string

GetDriveType = ctypes.windll.kernel32.GetDriveTypeA

for letter in string.uppercase:
print letter, "=>", GetDriveType ("%s:" % letter)

</code>

You'll have to refer to

http://windowssdk.msdn.microsoft.com.../ms685874.aspx

and various headers to get the values in question, but they
look quite straightforward at a glance.

These seem to map when tested on my system:

import ctypes

DRIVE_TYPE_MAP = dict( enumerate ( """\
DRIVE_UNKNOWN
DRIVE_NO_ROOT_DIR
DRIVE_REMOVABLE
DRIVE_FIXED
DRIVE_REMOTE
DRIVE_CDROM
DRIVE_RAMDISK
""".split()
))

## if you need the constants ...
for i, name in DRIVE_TYPE_MAP.iteritems():
exec( "%s = %d" %( name, i) )

GetDriveTypeW = ctypes.windll.kernel32.GetDriveTypeW
for i in range( ord( 'A' ), 1 + ord('Z') ):
path = u"%c:\\" % chr( i )
print path, DRIVE_TYPE_MAP[ GetDriveTypeW( path ) ]

Thanks, I'll give this a try. I appreciate everyone's input.

Thanks Tim and Rob... this works really well!
