Hi,
Am trying out Defraggler--on Win 7 Pro 7 64 bit--it appears to work OK on SATA drives (although C is ALWAYS reported at 30% defragged even after immediately running a full defrag!)
BUT worse, my two IDE drives simply cause Defraggler to freeze when trying to analyse--was thinking of purchasing the top version but unless / until these issues are sorted I will go back to Perfect Disk...
Hoping for a quick resolution?
