Disk Partitioning on a Mac Mini (new)


Recommended Posts

I'm getting my new 1TB iomega HD tomorrow and would like help partitioning my HD so I can backup my itunes. I'm going to use SuperDuper!

 

I want to backup my Mini (it only has the OS and programs) The other 1TB drive has my itunes music only.

 

How much room do I need to leave for the mini HD?

 

Thanks

You mean how much room for the backup image partition on the new 1TB drive, right?

 

If you only want one copy of the backup at any one time, and you are not going to use any kind of data compression for the backup image, technically you only need to make the partition slightly bigger than the amount of data currently in use on the mini. To find this amount, right click (ctrl + click) on your mini's drive icon and select 'get info'. The "used" data field would be your target size for the backup partition.

 

This would be a bit unpractical in practice though because you will most probably install more applications over time, and there WILL be updates from Apple that will use more space as well, causing you to need more room eventually.

 

What I do is set the backup partition size to about 10 MB more than the size of my whole system drive. I think I know what your next question might be: I do keep more than one backup image around, but on different drives, so that if the backup drive goes down, I still have a 2nd backup in another location. I don't think there is any sense in keeping more than one image of this type on a single drive.

 

I hope that this helped.

OK..I will leave at least 10MB on the new HD. Can anyone give me detailed instructions on how to do this? I'm a longtime PC guy NOT MAC.

 

I do not want to make a BIG mistake and loose all my music.

 

Thanks

.... comfortable with these instructions twrace: http://www.kenstone.net/fcp_homepage/partitioning_tiger.html

 

There are more answers here - the results of a google search for " how do I format and partition in Mac OS X" : http://www.google.com/search?client=safari&rls=en-us&q=how+do+I+format+and+partition+in+Mac+OS+X&ie=UTF-8&oe=UTF-8

 

If you don't find something that you think will help out there already extant, I'd be surprised, but I will do the best I can to help you further if you cannot find what you need.

 

Be sure that the partition you set aside for the backup image is formatted as "Mac OS Extended Journaled". You will want to be able to boot from this partition & that is the formatting scheme that you will need.

 

I hope that you won't think it rude of me to tell you to learn how to use the basics of your computer, but I was about an hour into creating a tutorial for this - only halfway done - when I realized that it had been done already probably a bazillion times and was there for the seeking on the web. It really ain't that hard, man.

thank you. Yes, I do need to learn MAC OS. I've been concentrating on ripping....

 

Should I format both in Mac OS Extended (Journaled)? One will be the OS and the other will be just the itunes music files.

 

thanks again.

It is I who feel 'thick' for not just pointing you to the web in the first place, spending an hour writing and taking screen shots ..... duh. The guy at the site I pointed you to did it MUCH better too. I'm sure he spent hours on it

 

I run all of my (Mac*only*) partitions as Extended Journaled, you don't HAVE to. In fact, you can switch Journaling on and off at will without damaging the data! You lose a little operation speed using journaling though - here is why I do it: http://support.apple.com/kb/HT2355 . Safety.
