Listing HD's

Hey, i was wondering if anybody could point in the right direction. Ie give me the name of modules and links to module listing etc for a method of listing what HD's a computer, under WinXP.

Thanks,
Chris

Re: Listing HD's

Is there a way of doing this properly or would i have to do something like this

drives = ["A:\\", "B:\\", "C:\\", "D:\\", "E:\\", "F:\\", "G:\\", "H:\\", "I:\\", "J:\\", "K:\\", "L:\\", "M:\\", "N:\\", "O:\\", "P:\\", "Q:\\", "R:\\", "S:\\", "T:\\", "U:\\", "V:\\", "W:\\", "X:\\", "Y:\\", "Z:\\"]
for drive in drives:
        if os.path.exists(drive):
                print drive, "Present"
        else:
                print drive, "Not Present"

So is that how i will have to do it, or is there an actual method to do that for you?

Re: Listing HD's

well I don't have a solution for you, but one thing worth mentioning about the way you have it done is this: every single drive that has a letter will be shown as present. This includes mapped drives, optical drives etc.

EDIT: I found the below link that may help, but it seems as if you have to have a 3rd party module to do it, because when i tried it it gave an error about win32file

http://mail.python.org/pipermail/pyt...ay/324479.html

Also instead of listing out all the drives like that in one huge array, you could just do the following if you like it better:

import os,string
 
for drive in string.ascii_uppercase:
        if os.path.exists(drive+":"):
                print drive+":", "Present"
        else:
                print drive+":", "Not Present"

Indeed this is a 3rd party module which is not what im after, and yes im aware that the solution i use will show all drives, this is in actual fact how i would like it. You have to bare in mind in only shows drives in use not blank CD drives etc. And again mapped network drives are also wanted.

Re: Listing HD's

well then in that case your solution seems to be the way to go

Re: Listing HD's

yes and ising string is the better option, i don't know why i didn't do that in the first place lol. O well thanks for reminding me. i May look int WMI (although it is an extra module) aparently has some functionality that could be of use to me.

Hope it helps

Re: Listing HD's

Yer its another example of a third party module by the looks of it, or at least a module that is no longer supported. I'd rather use default libraries and working with the solution i have at the moment since i would like to be able to rn the script on other machines that will not have the extra modules installed.

But thanks anyway, these were the sorts of things i was getting when i googled it myself.

Re: Listing HD's

I wouldn't stop there at all. Take a look at the source code for those 3rd party modules. Its most likely that they use the Win32 API (or another C api). If so you can use ctypes to just load the right DLL and call the needed functions directly from Python. No 3rd party module is needed. I have done this myself for other areas of Win32 API and it works just fine.
