Format the partition in Window 7

You can format a partition during the creation of it, as we did in above practice. If you have skipped it during the creation process, you need to do it before use.

If you try to use it before format, Window explorer will give you the following alert

"You need to format the disk in drive before you can use it. Do you want to format it?"

While you format a partition, it will delete any information on the partition and setup a file system so Windows 7 can read from it and write data to it.

To format a partition Select the partition from disk management console and Right click, from open context menu click format option


In opened popup box you can set format options. All options are same which you have seen in above practice.

  • Volume label :- Specify a name to this drive, default will be New Volume
  • File system:- Choose NTFS for better performance, Fat32 only available as options on drives 2GB and smaller
  • Allocation unit size :- This is the basic unit in which disk space is allocated. The default allocation unit size is based on the size of the volume and, by default, is set dynamically prior to formatting. Keep default.
  • Perform A Quick Format:- If checked window will format without checking the partition for errors. With large partitions, this option can save you a few minutes. However, it is recommended to uncheck this option and perform full format which will check for errors, mark bad sectors on the disk and lock them out.
  • Enable File And Folder Compression :- Built-in compression , only for NTFS file system. Usually not necessary in today's world of incredibly large hard drives.

Click OK at the bottom of the window
