Hi there. I'm looking for opinions, I have an older 17" MacBook Pro (Core 2 Duo, Mid 2009) and a newer 15" MacBook Pro (i7, early 2011) both of which are running Lion (10.7.2).  The older laptop has a new 7200RPM drive and the new laptop has a standard 5400RPM drive.  I'm desiring to swap the drives while leaving them intact with their existing OS installs.  Does anyone anticipate that there will be issues booting the drives after the swap, specifically because of the difference in processors, memory, video, etc?

 

Thoughts? Opinions? No brainer? Not going to work?  I just don't want to go through the hassle if someone out there has already tried it and ended up having to re-install from scratch.

 

Thanks for your help.

 

Bryan

    if your 5400rpm drive has a larger capacity than the 7200rpm one, say 500GB vs 320GB,

    the speed with the 5400rpm wont actually be noticeably slower, and the technology used on the traditional hard drives are improving (slightly) each year too.

    you wont likely feel anything different if you really go and swap them.

    and in fact, even with the new models, the speed of a 320GB 7200rpm HDD isn't much higher than a 500GB 5400rpm HDD.. you will see it in the benchmarks. so you might as well wanna just save yourself some time not going through this hassle. the amount of time you'll have to spend on optimizing and trying to make everything to work properly will make you regret the swapping. so i hope you dont have to go through that.

     

    if you are really intending to increase the speed to a comfortable level, try SSD instead, that'll truly bring you a difference

    You might as well go through the hassle of trying it out, because the hassle of reinstalling everything would be far greater. Because you have the same OS version installed on each drive, there's a chance it will work. There's also a chance that it will appear to work, or will mostly work, but that some functions won't work properly or at all. And there's a chance that the new machine won't boot at all. Try it and see.

    I knew I should have omitted the speed of the drives as that isn't my goal, my goal is to just "move myself over to the new computer without having to do a backup/restore" -- Just wondering if I'll run into "driver" issues on the new machine since the old machine's OS install is for a Core 2 Duo and the new machine is an i7.  Thoughts?

    It will take about 20 minutes for you to swap the drives. That's all you have to lose by giving it a try.

    I really do appreciate that answer but I'm hoping to hear from someone that has tried it.  I'm totally fine "just doing it" but I really wanted to hear about any potential pitfalls.

     

    Thanks.

    Okay, but in the time you've already spent waiting for the reply you want, you could have determined the answer yourself a dozen times over.

    I'm certain you are right with that.  I'm just not in any hurry and thought I would try to gleen some wisdom from any daring folks that have already tried it and learned any lessons.  No rush here, just fishing for anyone that has tried it.

     

    Thanks again.

    Bryan,

     

    Did you try this out in the end? I'm thinking of doing the same thing, albeit between a 17" Core 2 Duo and a 17" i7.

     

    Would be interested to know how it turned out your end...

     

    Thanks.

    I have cloned and moved drives from machine to machine regularly, usually there are no issues, when ther are a quick reinstallation of the OS fixes it. If you want to know in advance pull one of the drives, connect it externally to the other machine and boot.

    Bryan,

     

    a)

    irrespective, Yes, the 7200 drive will make a noticeable difference, noticeablly faster. 

     

    b)

    Unfortunately as I experienced, you cannot simply swap a core2duo running drive to an i7 machine. It will not work. Too may differenced for it to boot or be easily corrected. It is a real pain unfortunately, I spent a good amount of time trying different things.

     

    cheers

    At best it will be 30% faster, normally less than 15%, if the drive sizes are not the same it may not be faster at all.

    Maybe, maybe not, I boot an i7 iMac with an external disc that came from a Core@ machine and it works fine, as it is such a simple thing to test I believe the OP should try.
