Buy this one at your own peril. I have 20 years experience with PCs and this is the most harmful product I've ever used. I bought it to sort out my hard drives and get them all in nice order. In the end, several logical disk drives were lost. Considerable data was lost, and I've spent hours and hours struggling to recover my data- to no avail.It seems that the programme hangs the system, and then, as its writing to the hard disks, proceeds to corrupt and destroy file allocation tables and partitions. With this product, who needs viruses? Partition Magic damaged my computer worse than any virus!.For this product to work, you must be very lucky. If your computer hangs-- say good by to your data. You only have to read the list of error messages that signify catastrophic errors to realise that this programme is full of risk. I regret buying and using it, so it is relegated to the garbage can with the wish that they were liable for consequential damages.
