get disk usage details like free, used, available for windows drives with sizes in TB

[balakrishnan]

Hi,
I wanted to get disk space details of a windows drive like free, used and available. The total size of the drive is like 8TB, used 5.56TB and free 1.78TB.
Attempted with Filesys::Diskspace and Filesys::DfPortable, it gives me wrong results as seems like there is a limitation on handling disk size(i.e: max of integer 4 byte value).

The wrong usage details given for the drive as :
Total bytes: 41943035904
Total bytes free: 17095663616
Total bytes avail to me: 17095663616
Total bytes used: 24847372288


Please suggest me the other respective ways that supports in all higher version of Windows 2000 OS.

Thanks,
Bala.

a quick google turns up Win32::DriveInfo.

You can use sniff for determining if you need to use it (or a *nix counterpart like you're trying to use) or not. Re: cross platform scripts has a very rudimentary version of it demonstrated.

Filesys::Diskspace seems to be Unix-ish only, Filesys::DfPortable might have problems with NTFS.
A Windows-only solution could involve parsing the output of

`wmic logicaldisk where DriveType="3" get /format:csv`

using Text::CSV. If you don't want to exclude optical drives, mounted shares, etc, you can leave off the where DriveType="3" part.

Thanks you so much for your comments..
The concern here is, Windows 2000 doesnt support wmic.

I am just looking for the solution which should work in all Windows OS >= Windows 2000.

Try this:

C:\Windows\System32>fsutil volume diskfree c:
Total # of free bytes        : 143714562048
Total # of bytes             : 627247673344
Total # of avail free bytes  : 143714562048

Another option, you could use DBD::WMI with the following query:

Select DeviceID,Size,FreeSpace from Win32_LogicalDisk

Consider upgrading to a supported Operating System. http://support.microsoft.com/gp/lifean36

I'd recommend checking out Win32::DirSize. I've been able to use it on Windows Server 2008 without issue.

Looking at the XS/source for Filesys::DfPortable it should return the correct values, even on 32-bit perl's that do not have 64-bit integer support. It achieves that by returning the numbers as ascii strings.

The likely reason you are getting incorrect results displayed is that you are using printf with a "%d" format?

Have you looked through the older posts here? Cool Uses for Perl and Code Catacombs often have some really great places to start, especially for older systems.
For instance (code) Win32 disk monitor, email notify, event log and Domain Disk space check both sound like they would give you what you're asking for here.
