Several people have recently inquired about the location of the mbrscan and mbralign tools. The purpose of this document is to provide a link to each tool.
The mbrscan tool (version 1.2) is part of the VMware ESX Host Utilities version 5.0.

The mbrscan tool (version 1.5) and the mbralign tool is part of the VMware ESX Host Utilities version 5.1.

Please take a look at the Frequently Asked Questions page for the mbralign tool for more information.
Technical Report (TR-3747) covers guest filesystem alignment and the use of these tools. Abhinav Joshi links to a blog entry about this a in his his post.
