Here’s another way to get disk utilization using your PSDrives. This is a one line command.\u00a0 I’ve broken it up with the line continuation character. This only works locally, only queries PSDrives using the FileSystem provider and that
\nhave a value for the Used property.<\/p>\n

\n
\n
Get-PSDrive -PSProvider filesystem | where {$_.used} |<\/pre>\n
select Root,@{name=\"Size(GB)\"<\/span>;expression={($_.used+$_.free)\/1GB -as [int]}},`<\/pre>\n
@{name=\"Used(GB)\"<\/span>;expression={\"{0:F2}\"<\/span> -f ($_.used\/1GB)}},`<\/pre>\n
@{name=\"Free(GB)\"<\/span>;expression={\"{0:F2}\"<\/span> -f ($_.free\/1GB)}},`<\/pre>\n
@{name=\"PercentFree\"<\/span>;expression={\"{0:P2}\"<\/span> -f ($_.free\/($_.used+$_.free))}}<\/pre>\n<\/div>\n<\/div>\n
The only thing I’ve done is customize the output to show utilization sizes in GB and calculate a PercentFree value. The expression returns information like this:<\/p>\n
Root\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 : C:\\
\nSize(GB)\u00a0\u00a0\u00a0 : 75
\nUsed(GB)\u00a0\u00a0\u00a0 : 66.80
\nFree(GB)\u00a0\u00a0\u00a0 : 7.73
\nPercentFree : 10.37 % <\/span><\/p>\n
Root\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 : F:\\
\nSize(GB)\u00a0\u00a0\u00a0 : 75
\nUsed(GB)\u00a0\u00a0\u00a0 : 7.53
\nFree(GB)\u00a0\u00a0\u00a0 : 67.00
\nPercentFree : 89.90 %<\/span><\/p>\n
You could also pipe this expression to Format-Table<\/strong> to make a nicer looking report.<\/p>\n

Download the oneliner here.<\/a><\/p>\n
UPDATE: Since I originally posted this I realized I made a grievous error. This oneliner likely won’t work for you, and definitely not on PowerShell v1.0. I normally test on all versions but missed something this month. My apologies. Here is a comparable expression that uses WMI to achieve the same results.
\n
\nget-wmiobject win32_logicaldisk -filter \"size > 0\" |
\nselect DeviceID,@{name=\"Size(GB)\";expression={($_.size)\/1GB -as [int]}},`
\n@{name=\"Used(GB)\";expression={
\n\"{0:F2}\" -f ((((($_.size\/1mb) - ($_.freespace\/1mb))*1mb)\/1gb))}},`
\n@{name=\"Free(GB)\";expression={\"{0:F2}\" -f ($_.freespace\/1GB)}},`
\n@{name=\"PercentFree\";expression={\"{0:P2}\" -f ($_.freespace\/$_.size)}}<\/div>\n
