Function Get-SdtVolumeInfo { <# .SYNOPSIS Displays all disk drives for computer(s) passed in pipeline or as value .DESCRIPTION This function return list of disk drives including mounted volumes with details like total size, free space, % used space etc. .PARAMETER ComputerName List of computer or machine names. This list can be passed either as computer name or through pipeline. .EXAMPLE $servers = 'Server01','Server02'; Get-SdtVolumeInfo $servers | ft -AutoSize; Ouput:- ComputerName VolumeName Capacity(GB) Used Space(GB) Used Space(%) FreeSpace(GB) ------------ ---------- ------------ -------------- ------------- ------------- Server01 G:\ 559 417 75 142 Server01 C:\ 68 60 88 8 Server01 E:\ 931 273 29 658 Server01 F:\ 4488 2662 59 1826 Server02 C:\ 136 61 45 75 Server02 E:\ 279 77 28 202 Server02 F:\ 1003 863 86 140 Server02 G:\ 674 483 72 191 Server names passed as parameter. Returns all the disk drives for computers Server01 & Server02. .EXAMPLE $servers = 'Server01','Server02'; $servers | Get-SdtVolumeInfo | ft -AutoSize; Output:- ComputerName VolumeName Capacity(GB) Used Space(GB) Used Space(%) FreeSpace(GB) ------------ ---------- ------------ -------------- ------------- ------------- Server01 G:\ 559 417 75 142 Server01 C:\ 68 60 88 8 Server01 E:\ 931 273 29 658 Server01 F:\ 4488 2662 59 1826 Server02 C:\ 136 61 45 75 Server02 E:\ 279 77 28 202 Server02 F:\ 1003 863 86 140 Server02 G:\ 674 483 72 191 Server names passed through pipeline.
