When you try to format a hard disk (in My Computer,
right-click the hard disk, and then click Format
), you may
notice that both the File system
list and the
Allocation unit size
list do not contain any entries. You
cannot format the drive.
This behavior may occur in the following situation:
- The hard disk is larger than 32 gigabytes (GB).
- The hard disk is either a removable drive or an external
drive that is optimized for quick removal.
To work around this problem, reconfigure the drive so that
it is not optimized for quick removal. To do so:
- Click Start, right-click My
Computer, and then click Manage.
- Under Storage, click Disk
- In the lower portion of the right pane, right-click
Disk number (where
number is the number of the hard disk that you want
to optimize, for example, Disk 1), and then click
- Click the Policies tab, click
Optimize for performance, and then click
- If you are prompted to restart the computer, quit all
running programs, and then click Yes.
