First, thank you for taking the time into reading my question/concern. We have 90 PC users, and 5 servers. In the past month, I have had 2 drives fail. Granted, Disk Defragmenter won't prevent hard drive failure, but I may have been alerted to a sector or a portion of a drive not decrementing files correctly as needed. Being that said, I have been reading mixed reviews in regards to one being better than the other. After spending a few days researching, I decided to turn to you, in my opinion the experts of your networking environment. What I'm looking for is advice and or recommendations as to what would be the best and most productive investment in disk decrementing software. What are your experience and or thoughts as to which product produces better results over all. Your comments and opinions are greatly appreciated.
