function Get-DbaDiskSpace { <# .SYNOPSIS Displays disk information for all local disk on a server. .DESCRIPTION Returns a custom object with server name, name of disk, label of disk, total size, free size, percent free, block size and filesystem. By default, this function only shows drives of types 2 and 3 (removable disk and local disk). Requires Windows administrator access on SQL Servers .PARAMETER ComputerName The target computer. Defaults to localhost. .PARAMETER Unit This parameter has been deprecated and will be removed in 1.0.0 All properties previously generated through this command are present at the same time, but hidden by default. .PARAMETER CheckForSql If this switch is enabled, disks will be checked for SQL Server data and log files. Windows Authentication is always used for this. .PARAMETER SqlCredential SqlCredential object to connect as. If not specified, current Windows login will be used. Only relevant in combination with the -CheckForSql parameter. .PARAMETER Credential The credentials to use to connect via CIM/WMI/PowerShell remoting .PARAMETER ExcludeDrive Filter out drives - format is C:\ .PARAMETER Detailed Output all properties, will be deprecated in 1.0.0 release. Use Force Instead .PARAMETER Force Enabling this switch will cause the command to include ALL drives. By default, only local disks and removable disks are shown, and hidden volumes are excluded. .PARAMETER CheckFragmentation If this switch is enabled, fragmentation of all filesystems will be checked. This will increase the runtime of the function by seconds or even minutes per volume. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .EXAMPLE Get-DbaDiskSpace -ComputerName srv0042 | Format-Table -AutoSize Get disk space for the server srv0042.
