Clean install of Windows 7, unpartitioned FAT32 formatted Kingston DataTraveler. Opened up disk defragmenter and selected my hard disks (C, F, System Reserved) and hit the defragment button. I left a few seconds later, all the hard disks were analyzing and nothing was happening to the flash drive. Came back after an hour and discovered that my flash drive had been defragmented too. Is there any way to prevent this from happening again?
