I recently finished my first PC build, and have everything up and running well. I installed Windows 10 on my SSD, and I have a 1 tb HDD that I plan to use for pictures, music and things like that. I formatted the drive, and it appears to be ready to be used for storage, but there is no file system on it like what is on the main drive with windows. I am really new to all of this, so pardon me if it appears obvious to you. What do I do to have a file system on the drive? Or do I need to worry about that. I realize I can create folders and create my own file system, but on the main drive, it already has directories set up for me, like programs, and documents etc. I hope this makes sense, as its hard to explain for me. Does partitioning the drive do that? Is there a windows tool that does that for me? Thanks so much for the help. This community is absolutely wonderful in helping people.
