Hi. I recently had the XP Disk Defragmenter analyze my honking 120 GB WD JB drive which lives in a USB 2 enclosure. It said the drive needed defragging even though it's only about a quarter full. Basically the drive contains huge backup files for my recording and system drives. Well, the defragging started and basically took forever. That got me to thinking whether or not the drive really needed defragging or not, and whether or not USB 2 external drives can be properly defragged by Disk Defragmenter. A test restore after the defragging operation was performed correctly. Any thoughts?
