[SOLVED] Show Hard Disk Drives on Windows Computers

[exploder]

???

I am looking for a way to find out what the hard disk drive letters are on windows computers on the network.  I need to keep up with the hard drive free space on these machines which I can do with the "freediskspace()" function,  but I need to first find out how many drives the computers have - some have a C drive only, some have C and D, others have C E and F.  I need to know how to get the drive letters and make sure they are hard drives and not cdroms or mapped network drives.

 

I think vb script has something like "("Select * from Win32_LogicalDisk Where DriveType = " & HARD_DISK & "")" but I need to do it in php if at all possible.

 

Thanks in advance for any assistance.

Would this work for you?

 

for($i = 65; $i <= 90; $i++)
{
$size = numf(@filesize(chr($i).":"));

if ($size > 0)
	echo $size."<br />";
}

Someone in the manual gave an example of how to list all drives, free space, total space and percentage free.  I suppose you can find out whether it's a cdrom drive or not by virtue of the numbers the code produces, but AFAIK there's no way to figure out whether it may be a mapped network drive or not.

Thanks for the replies broken and crayon....Im surprised I haven't seen this before.  I tried it and it looks like it will do the trick, I just need to get it to run through a list of machine hostnames.  I intend to run it as a cron job or scheduled task and generate text files, then just parse the text files with the web page, probably load the page quicker. I found a Pear package called WinDrives but it looks like it would have to be executed from a windows machine, still nice though.  I guess we can mark this as complete, thanks. 

 

Just curious - Why does this for loop use 65 to 90 ?

He's passing it through chr() which returns the character from the value that you pass to it.  I think 65-90 is like A-Z or something.

That's exactly right

Yeah, I knew what it was doing, but I was too lazy to actually count the numbers to see if it was actually the right amount of letters, lol.

Oh ok.... chr()

 

On the machines I have tested it on so far, mapped network drives do not show up which is fine, I don't want those.  I hope that's the way it's intended to work...

Earlier I told you that I didn't know if there was a way to tell if it was a mapped network drive or not, but I just read one of the notes for the link I gave earlier:

Note: This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.

 

So yes, that is working as intended.
