So basically I plan on building a PC. I have 2 HDD's from my old PC. One has the OS and the others have the data. My question is whether I can transfer these hard drives to another PC? I know windows does not like hardware changes. If that does not work, can I go back into my old PC and wipe the hard drive with the OS using dban.org ? And then reinstall windows onto that harddrive and put it into the new PC with the HDD with all my data? Will that keep all my files as they were?
