I have fully defragged my hard disk with Norton System Wokrs (Speed Disk) that wasn't give a good job (some files still fragmenteds).
So, at the end of all process I open the Defraggler and I selected all the remain files and I click on defrag highlighted, the Defraggler frezze 20% and the cpu usage was low and the light that indicates write/read in hard disk was blinking...
I wait 20 minutes and I reboot my machine manualy...
At the end I have more files fragmented that normal!!! lol
I not lost any data, have lucky...
I think this bug occured by system files selected... But I don't have sure if I selected any...
PS. My pc:
Motherboard with chipset AMD690G (A690GM2MA-Foxconn)
Athon 64x2 5600+ (2,8Ghz)
2 DDR2(800Mhz) with 512 (1024Mb of memory)
Hard Disk faster, I have sure. (SATA2) ~ I don't know what model...)
ATi x1550 Series ET (512Mb)
