This blog will provide technical data and insights into performance and reliability issues surrounding file system performance.
We hope to cover all topics related to system performance including defrag whether you are running SANs, NAS, workstations, servers,
SSD's or other systems. We will provide interesting anecdotes, white papers, and related story topics on defragmentation and other
performance issues. The blog is intended to be personal rather than a formal Diskeeper website. You will read personal viewpoints
on our products and where we see the industry and our company going. We are excited to have this opportunity to share our product
knowledge and insight, and hope this information helps you. We encourage your comments and look forward to you following this blog.

“A group of MVPs have been discussing disk wiping. Could you please provide more details of exactly how your wipe is performed and how it meets NSA/DOD standards?â€
Undelete 2009 uses the following DoD overwrite patterns:
1. Bit pattern #1 = Any Bit Pattern, such as ‘00110101’
2. Bit Pattern #2 = A Bit pattern that is a Ones compliment of Bit pattern #1. For the above case, it would be ‘11001010’.
3. Bit Pattern #3 = Just a random bit pattern
