My computer was getting slow and I had not defragmented the drive in a year, so I set myself to the task. I used a third party program that was faster and used less system memory than Windows defragger. The defragger “Defraggler” worked flawlessly on my computer.
I had an external drive, which I decided to defrag. Defraggler would not work on the external drive, a USB drive connected to my computer, which is a laptop. So, I went looking for a way to defrag my external drive and found your site. Someone had asked that question, and I followed your instructions to right-click the drive and select defrag from the menu, and Windows defrag would defrag the drive. The external drive had only 10% of the drive’s size in data, but if I remember right, defrag does not distinguish between data and empty portions of a hard drive.
I set defrag to work using another 3rd party program called “No Sleep”, which simulates a person moving the cursor, so the computer doesn’t shut down. Then I went to bed. When I awoke the computer was hung up, and I had to back out of defrag. When I looked at my external drive almost all of the data was gone.
The external drive was a backup of sorts, and it was not itself backed up. I hadn’t gotten around to that. So, hundreds of hours of work was lost. I started by going back on the web and found an article that warned that Windows defrag often hangs up on large drives. My external drive was a terabyte in size. The lack of warning for this on your site led to the loss of my data.
I have 8 recovery programs, all third party, which I rarely use. Six of them could not recover anything. The seventh recovered everything. So, I’m whole. But you need to add a warning in your instructions to warn people that Windows defrag has problems with large drives … and maybe small ones. I never have used Windows defrag since I was alerted to the existence of third party programs that do a better job of defragging.
