Make new [Hard Drive] but Keep the Old
For Christmas I got a new SSD that I plan to use to boot Windows/games. However, I have a lot of data that I use for work that would be way to much for a (or at least my) SSD, so I will be keeping my old HDD. My question is: Is it possible/wise to have my old HDD just exist without formatting, or will I need to reinstall everything on it from scratch? From my google searches it seems that I'll need to reformat if I want to use both drives simultaneously, or at least to be able to have installed programs run from the old drive, which seems right but I just wanted to make sure it was necessary before going through that process.
