Hello, I have a 500 gb external hard drive I want to partition into two parts, one for my Time Machine backup, and one for some general file backup I keep on an older hard drive. My problem is, I already have had my Time Machine running since I bought my Macbook. So my question is, can I partition the 500 gb hard drive like I want and keep my Time Machine data? If not, is there a way for my to transfer my Time Machine data to my old hard drive and transfer it back after I partition the 500 gb hard drive? Thanks in advance for the help.
