Old hdd and os into new build Tags: New Build Hardware Hard Drives New Build Systems Last response: December 2, 2011 2:25 PM in Systems Share allinhands December 1, 2011 10:35:17 PM Hello everyone I just built my new pc and i reused my old hard drive. Everything works fine with my old info and windows 7 and i installed all the new drivers for the new hardware. My question is can i keep it that way (noting that everything works fine now) or do i still have to format the hard drive and reinstall os. If something eventually goes wrong later on would be software only related or it can impact the hardware? Thanks a lot More about : hdd build COLGeek December 2, 2011 12:18:04 AM If everything is working properly, then just leave well enough alone (no install necessary). Make sure to re-activate your system. Good luck! m 0 l allinhands December 2, 2011 2:15:47 PM Thanks for the reply! I just wanted to make sure that i cant do anything wrong to the new hardware.
