+ 0 Votes I though my comment would attract attention, so ... OldER Mycroft 4 years ago Here goes: This user wants to transfer executable files from HDD#1 to HDD#2, then format HDD#1 to use as a 'new' storage space. Fine - until he reinstalls the programs that used to sit on HDD#1 (on HDD#2) then finds that HDD#2 either slows dramatically or throws up all kinds of missing links, due to the registry STILL having entries related to programs that no longer exist. This is all assuming (obviously) that his OS was originally sitting on HDD#2. If he just formats the HDD, that won't clear out all the now-orphaned registry entries!
