The new format behavior may cause problems for the on-demand allocation modes that a volume storage provider, such as a Storage Area Network (SAN), supports. Problems may occur because the new format behavior prematurely triggers allocation of the backing space.
In the on-demand scenario, zeros do not have to be written to the whole disk because the volume storage provider initializes the on-demand-allocated data. To avoid causing unnecessary on-demand-allocation, you must use the quick format option.
You can use four methods to format a volume in Windows Vista and later versions. You can use the quick format option for these four methods:
- Command line: Use the format /q command.
- Diskpart: Use the format command together with the quick parameter. For more information, go to the following Microsoft website:
- Windows Explorer: Click to select the Perform a quick format check box.
- Disk Management (Diskmgmt.msc): Click to select the Perform a quick format check box.
