Currently all my Time Machine backups are on the same Hard Drive where I store all kinds of other stuff. The backups are starting to max out the drive so I plan on buying a new seperate external strictly for backups.

 

What I want to know is: when I choose the new drive for my backups and do the first initial backup, will that unlock all the other ones on my old drive for deletion?

    I'm not sure if I have understood your question. In Mountain Lion, when you use another disk for Time Machine, Time Machine will backup on both your external hard disks and it will only delete backups on your older disk if it hasn't got space

    I only want one external drive to hold my backups.

     

    I guess basically I just want to know once I select the new drive for everything, how do I delete everything off the old drive as those backups take up a lot of space that I would like cleared.

    If you want to save your old backup and continue to use it, you should be able to copy it from your current external hard drive to a new one. You can then reset Time Machine in System Preferences to look at the new drive. I have done this several times as I have rearranged external hard drives.

     

    If you just want to delete your current backup, you should be able to do that also.

    Well I have attempted to delete old backups by just dragging them to the trash but every time I try to empty the trash is says that those items are locked?

    To erase the whole drive, open Disk Utility and erase that disk. Check > http://www.thexlab.com/faqs/trash.html#Anchor-Locked-48213

    Well like I said there are other items on the drive that I want to keep so I can't reformat that whole thing because I will lose that data. I dragged everything to the trash and used the option key to empty it and now it is showing a negative number amount of items to be deleted?

    Get the new external drive. Copy the files you want to keep from your current drive to the new external. Erase the old drive. Move the files back to the old drive. Run Time Machine on the new drive.

    New drive will be smaller (500GB) than the drive that I currently am backing up to (2TB). New drive will be used strictly for backups as I do not want to run into the problem that I am having now.

     

    Basically what everyone is saying is that the easiest way to do this is going to be just wiping out the drive via disk utility and that every other way is just a pain.
