Problem backing up to time machine

[hohohong]

I had a MBA for about 2 months now and a 1TB HD that is hooked up to the Extreme router.

Just bought a mini and was trying to do back up. Set up the time machine to back up to the 1TB HD. The time machine logo is spinning (backing up), but it has being doing that for 24 hr?? And the status is always "preparing backup".

So I hook up the HD straight to the USB of mini, but still the same,.... what's wrong?

And I'm looking to upgrade the HD and is looking at:

http://www.newegg.com/Product/Product.aspx?Item=N82E16822136314

and

http://www.newegg.com/Product/Product.aspx?Item=N82E16822148371

Either of them is compatible with Mini right? Any recommendation?

I've already installed my program into the stock 160GB HD. What's the easiest way to transfer what's already on that 160GB into the new HD?

Problem solved

I figured out the problem.

Everytime when I reboot the mini, a "Where is System Events?" window will pop up. I thought it was a bluetooth firmware update as that was the active program when the window pop up.

I googled it and found out that I have to go to:

/System/Library/CoreServices/System Events.app

And once that's done, I can update my time machine.

I post this so that anyone else with the same problem can fix this issue easily.
