    Hi!

    I've upgraded my iMac with an SSD, now I have 1 SSD and 1 HDD. So, I've installed the mac OS on the SSD, and now I don't need the system (files) on the old HDD, on which are my stuffs, like movies, pictures etc. I want to remove all system files which are on my old HDD. How should I do it? Just delete manually everything together with the hidden files also?

    Do you need anything that's on the HDD? If not just reformat it.

    Yes, I definitely need all the stuffs, mostly cause of my mp3 collection, there is 400 GB music, but the rest I need also.

    If you have room enough on the HDD, I suggest that you LEAVE THE OS ON IT.

    Why?
    Because you ALWAYS WANT TO KEEP A SECOND BOOTABLE DRIVE AROUND.
    (shouting intentional)

    How many posts have you seen here from folks who can't boot, and who are flopping around like a fish out of water trying to figure out what to do next?

    If you have an SECOND bootable drive within reach, it becomes "child's play" to get the Mac booted and running again if there's a problem with the internal drive.

    So... if you "need the space", ok, dump the OS files.
    But if you don't... keep that bootable second drive handy, because you never know when you might need it !

    Copy all your stuffs onto your new SSD, and then format the old drive using Disk Utility.

    You should invest in putting your Music and videos on and network NAS device to save space on your SSD! The video files will be the largest!
