SYMPTOMS
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.



CAUSE
This behavior may occur in the following situation:
 * The hard disk is larger than 32 gigabytes (GB).

-and-
 * The hard disk is either a removable drive or an external drive that is optimized for quick removal.



WORKAROUND
To work around this problem, reconfigure the drive so that it is not optimized for quick removal. To do so:
 * 1) Click Start, right-click My Computer, and then click Manage.
 * 2) Under Storage, click Disk Management.
 * 3) In the lower portion of the right pane, right-click Disk   (where   is the number of the hard disk that you want to optimize, for example, Disk 1), and then click Properties.
 * 4) Click the Policies tab, click Optimize for performance, and then click OK.
 * 5) If you are prompted to restart the computer, quit all running programs, and then click Yes.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
