What happens at 10% done?

[Moshup Trail]

This was true in earlier versions of Windows too.
When you use the defragmenter tool, it always cruises to 10% completion and
then seems to just drag to a stop for a long time. Eventually it takes off
again and completes just fine.

What happens at 10%? What's it doing?

Anyone else notice this?

This may help, I think this applies to Windows XP as well (at least if
we talk about FAT32 drives here): "Description of Percent Complete
Values in Disk Defragmenter"
(http://support.microsoft.com/?kbid=131648).

At that point it has assessed what files are on the disk and is doing a
complex calculation to decide what is the optimum layout for them
