Hi guys, I could really use some help - this wasn't what I planned for New Year's Eve

 

I hope my info below makes sense (I am not 'technical', but I have followed common sense info found online):

 

Due to a malfunction with my original MacPro hard drive that was unsolvable using Disk Utility or Drive Genius 2, I had to erase it and re-install Lion (My machine is sadly too 'vintage' for Mountain Lion).

 

When I was reinstalling Lion, I tried to restore my MacPro from external back-up but I had an error saying there was not enough space, which is rubbish, as it is was the source! On researching this, I decided the best bet was to erase the hard drive.

 

I still have everything saved on an external Back-up drive (from using Time-Machine). I do not want to launch Time-Machine at the moment, because it will over-write the back-up drive which I need to access. I am making a copy onto my second internal drive - 'Mothership')

 

Basically I want to restore the current empty (restored, errors solved) MacPro drive with the information that was on it (including all my applications etc.) Fortunately, my Home folder and work are all on Mothership. All the problems started when I moved my Home folder from MacPro to Mothership due to needing more Start-up disc space.

 

Can I replace the current hard drive info with the old one? (Bearing in mind that Time Machine facility will have no memory of anything prior to my erasing the disc, just what's on my back-up)

 

Thanks.

    Assuming that your Time Machine backup is on a locally attached drive, rather than on the network, you should be able to boot from it into Recovery by holding down the option key at the startup chime. Select its icon in the screen that appears.

      

    From the Mac OS X Utilities screen, select Restore From Time Machine Backup. You can select a snapshot and a destination volume. The contents of the snapshot will replace the existing contents of the destination.

     

    There are various reasons why this procedure might fail, but most of the time it works.

    Did you format the destination volume as case-sensitive? If so, reformat it as "Mac OS Extended (Journaled)."

    As I write I am attempting to migrate files over to Mac Pro from Back-up using Migration Assistant.

     

    That will cause other problems, but you seem to have decided what to do, so I'll leave you to it.
