transferring from external hard drive to new iMac

I got a new iMac with a huge hard drive. I'd like to transfer all my data from my external hard drive into my new iMac computer. What the correct way, and the best way to do that?


Thank you.

Hello Mary Anne:


I would probably attach the external HD and copy the information. Of course, the destination would depend on what kind of data you are transferring.

As maurits6814 has asked, this answer may not apply if you're transferring data from a hard drive used with a PC.


But...if you're transferring your data from a Time Machine backup from an older Mac, the best means of doing this is via Setup Assistant, which runs once (and only once) when the new iMac is first powered on.


The next best means is via Migration Assistant. Migration Assistant can be run at any time, and can be found in Applications --> Utilities. I would urge you to read the excellent information provided by "The Great Pondini" at the URL linked below, as it will probably answer just about any question you might have regarding transferring everything over:

I hope this helps!

Thanks everyone.


I have a new iMac. And I was using an old iMac. I've already transferred everything from the old iMac to the new one using the Migration Assistant. It successfully transferred everything from the iMac hard drive. But now, I still have my external HD, which holds all my iTunes content like music, shows, etc, plus my iPhoto library. So it's a lot. My new iMac has a 3T drive, so it has enough space for me to transfer all the stuff from the external HD into my new iMac.


Can I just drag all the stuff into the new computer?


Thanks,

MaryAnne

You can....


For your iPhoto library, just find it on your external drive and drag it over to your internal drive. When you open iPhoto, you'll have to tell it where the library is, of course. (Note: Do NOT drag the individual photos over...you'll cause serious issues with your iPhoto library if you do it this way).


For iTunes, here's a link that will help walk you thru things:

All in all, not hard to do at all....and you'll have everything on your internal drive.


Of course, you'll want to run a Time Machine backup as soon as you can after moving everything.


I hope this helps....

Actually, Mike, there's been a problem. Everything was going well, I had the files copying over to my new iMac during the night (there's a lot of shows and movies to transfer), and the I woke up this morning to find a window with the message, "Copying files failed. The disk could not be read from or written to."


Shoot.


What do I do now?


-Thanks.

Hello:


I have never done anything like you describe, so I do not want to give you bad advice (I always use migration assistant when I go from one system to a new one but I always have everything on my internal drive).


If what you are trying to move is in an iTunes library, this knowledge base article may help:

If the data is just stored on the external HD, that article will not be of much help. I think I would drag it to a folder on the new system desktop - that can always be deleted.

I wonder if your computer went to sleep during the file transfer? I might try it again if I were you, but before doing so go to System Preferences and change your settings to never sleep (until you're all done...you can change them back afterwards).


Since there's no problem with the external hard drive after following Barry's suggestion to run Disk Repair, that drive is fine.

Thanks again for the input!


Mike: no. that's not it, because when I try doing it again now, within 5 minutes it stops again. Strange because the window popped up last night before I went to bed after copying the files fine for at least an hour or 2. Not sure what's happening, but my husband will try tonight. He might have the focus to figure this out.


Barry: Yes, it is an external HD, so not sure how it will work.


Will let you know the outcome.


Thanks,

MaryAnne
