I too purchased the BlacX Duel box about a year ago with the intent to transfer programs and data from my old computer to a new computer. Both hard drives have data on them and the documentation isn't clear enough for me to possibly erase the data on the newer computer. I have Windows 7 on the old computer and Windows 8 on the new. First, can I transfer the existing programs via the BlacX Dual box? Second, I need better instructions on how to do this. I know little about the internal workings of computers. Thanks in advance for some help.
