New Windows Storage

Sometimes one just has to add new storage to a Windows installation. And in some cases like adding physical storage there are a few simple steps like below.

Values like disk number you can get from the disk handling GUI in Windows (right-click Windows).

 

1) Initialize disk

Initialize-Disk -Number 2 -PartitionStyle GPT

2) Create partition

New-Partition -DiskNumber 2 -UseMaximumSize -DriveLetter S

3) Format volume

Format-Volume -DriveLetter S -FileSystem NTFS -NewFileSystemLabel Spare -Full:$false -UseLargeFRS

If you are adding more than 8 TB or know that the storage mostly is for a few large disks the add the CmdLet parameter -AllocationUnitSize 64KB. Add the CmdLet parameter -UseLargeFRS to use large File Record Segment (FRS) when files are created, altered and deleted often.

 

If the storage unit is reused from another Windows installation, then the unit can be wiped like this

Clear-Disk -Number 2 -RemoveData

If the disk holds one or more OEM recovery partition the add the CmdLet parameter -RemoveOEM.
