I am trying to find out (using Python under windows) the name of a CD that
is currently in the drive specified by a path name.
And while I am at it, I'd also like to know whether the specified drive
contains a CD at all, and whether the drive is actually a CD drive.
AFAIK, Python doesn't provide a way to do it, and a search in the web
yielded only soutions for Linux.
Can anyone show me a solution that works with windoze?
TIA,

There are sure thousand ways
of doing it "with windoze".
Here one of them (NOT tested) in form
of code snippets you can rearrange
for your purpose:
import win32com.client
axFSO = win32com.client .Dispatch("Scri pting.FileSyste mObject") # SCRRUN.DLL
axLstDrives = axFSO.Drives
dctAXaxFSO_NumC odeAsKeyVsTypeD escrText = {
0 : "unknown type of drive"
, 1 : "drive with removable medium (e.g. Floppy)"
, 2 : "fixed drive (e.g. harddisk)"
, 3 : "remote (i.e. network) drive"
, 4 : "CD-ROM drive"
, 5 : "RAM-Disk drive"
}
lstdriveLetterO FonSYSTstorageD evice = []
lstdriveTypeOFo nSYSTstorageDev ice = []
for axDrive in axLstDrives:
if(axDrive.IsRe ady): # checks if a CD is inserted
lstdriveLetterO FonSYSTstorageD evice.append(
axDrive.DriveLe tter.encode()
)
lstdriveTypeOFo nSYSTstorageDev ice.append(
dctAXaxFSO_NumC odeAsKeyVsTypeD escrText[axDrive.DriveTy pe]
)
# axDrive.SerialN umber
# axDrive.VolumeN ame.encode()
# for more of this kind just check out e.g. in the by Microsoft
# free available JScript tutorial the chapter
# "FileSystemObje ct Sample Code"
#:if
#:for
Hope this helps.

This works. The only thing you have to do is stuff a floppy into the
drive & find out what the fstype is (that's inf[-1] in the code below)
so you can key on it. Try the docs for Mark Hammond's Win32, and
there's always his _Python Programming on Win32_.
import os
import os.path
import win32api
def findCDs():
cdDrives=[]
print "Searching for cd drives..."
drives=win32api .GetLogicalDriv eStrings().spli t(":")
for i in drives:
dr=i[-1].lower()
if dr.isalpha():
dr+=":\\"
inf=None
try:
inf=win32api.Ge tVolumeInformat ion(dr)
except:
pass # Removable drive, not ready
if inf!=None:
if inf[-1].lower().endswi th("cdfs"):
cdDrives.append ([dr,inf])
elif inf[-1].lower().endswi th("udf"):
cdDrives.append ([dr,inf])
return cdDrives
inf[0] contains the volume label if there is one and if there's a CD
loaded: win32api.GetVol umeInformation( "c:\\")
('God_C', -798323922, 255, 459007, 'NTFS')
Note that you must use the full drive spec, "letter:\\" or
GetVolumeInform ation() doesn't always work.
There are probably better ways to do these things, but they do work;
I've been using them constantly the last few days.

Ivan

Hi All--
Tim's wmi stuff looked interesting, so I tried it out, and now I have a
question.
-----
#!/usr/bin/python
import wmi
import win32api
c=wmi.WMI()
for i in c.Win32_CDROMDr ive():
v=i.VolumeSeria lNumber
print "WMI serial",v,long( v,0x10)
vn,sn,ln,flg,fs type=win32api.G etVolumeInforma tion("d:\\")
print "win32api serial",sn,long (sn)
----
The output from the above script (drive d contains cd) is:
WMI serial D0ADBEE7 3501047527
win32api serial -793919769 -793919769
What's the difference between the two serial numbers? WMI is returning
a long converted to a hex repr string, while win32api is returning an
int (type(sn) is <type 'int'>), & converting to hex bears no resemblance
to what WMI shows. What am I missing?
Metta,
Ivan

Maybe the function below can help?
I suppose WMI returns same values as FSO (File System Object):
def strDriveHexSeri alNumberFromFSO intRetVal(intDr iveSerialNumber ByFSO):
"""Supplied with an integer representing a drive serial number returns the
number in same format as \>dir command does (i.e. ####-####)."""
# The value of axDrive.SerialN umber property (an int or float number) can
be
# negative, so to get always a positive number as listed by e.g. \>dir
# command it is necessary to apply a workaround:
if(intDriveSeri alNumberByFSO < 0):
# dec 4294967295 == hex FFFFFFFF, dec 4294967296 == hex 100000000
intDriveSerialN umber = 4294967296L + intDriveSerialN umberByFSO
else:
intDriveSerialN umber = intDriveSerialN umberByFSO
#:if/else
strHexSerialNum ber = "%08X"%intDrive SerialNumber
strHexSerialNum ber = strHexSerialNum ber[:4]+"-"+strHexSerialN umber[4:]
return strHexSerialNum ber
#:def strDriveHexSeri alNumberFromFSO intRetVal(intDr iveSerialNumber ByFSO)
In your case
strDriveHexSeri alNumberFromFSO intRetVal(-793919769):
gives:
D0AD-BEE7
