Okay - thanks for the prompt reply. The C,D and E logical disks are not mirrored but I do back up the message data elsewhere on a regular basis. I will go with your recommendations and I think all will be fine - just thought it wise to ask.

Thanks again.

Hello, I have started testing and then using your defrag product on our servers and some of our workstations with good success. It has successfully defragged drives that the Windows defragger wouldn't - thanks for sharing your great product. I thought I would double check/ask about using it to defrag our Exchange server - it is a Server 2000 machine that is running Exchange 5.5. I have run the Windows defrag in the past with no known issues but I would like to try your product as it has seemed to do a better job on other drives. Is this okay to do? Anything that I should be aware of or be careful about?

Thanks in advance.
