change hard disk

Solution
Yes. Be careful with the spray paint; if it blocks the "breathing hole" you could have problems with the drive.

OK, seriously. With proper disk cloning software, you can make an exact copy of the existing disk to a new one, then physically swap the disks. The system should boot just fine. Two questions: what kind of PC and hard drives (notebook, desktop, supercomputer) and why do you need to swap the drive?
