Bought a used 2012 macbook pro, want to transfer data from old, broken mac

[peytonbroncs]

So i Just bought a used macbook pro 2012 today because I had one for many years but broke it last weekend. I dropped the computer into a tub of water and haven't tried to turn it on since but it's probably fried for good. I had 2 SSDs in there which are still working, but I don't know how to recover the data fully. Should I install the 2 SSDs into the new computer and the data should be all there? I bought a hard disk drive encloser from best buy to see if the hard drives still work, both hard drives don't show up when plugged into the mac (as an external drive). However, both hard drives show up on my friend's chromebook and seem to be working fine. What I did with the old SSDs when I first installed them on the old mac was combined them together into one RAID and 500gb hard drive through the mac's software (each one was 250gb each). So do I have to install the 2 SSDs into the new mac for the computer to retrieve the data? If I do this, am I risking the computer at all because of possible water damage to the SSDs (although when I took out the hard drives they were very dry)?

I also had 16gb RAM in the old mac, is there any way to test if that RAM is still good? Is it worth trying to install into the new mac or am I taking a risk because of possible water damage to the RAM?

The new mac is mid 2012 13in. running 10.14.3 (Mojave)

Thanks for any advice in advance!

If the SSDs are not completely dry, I would not use them until you are 100% certain they are dry. If there weren't completely dry when you tested them, they may work without issue for a while and may suddenly fail without warning.

Which version of raid was running on the SSDs?

Putting the ram into the new Mac should not affect the new Mac. Even though the new Mac will boot with the old ram, it would be best to run a memtest on the ram.

There should be little to no risk of damaging the new Mac with the SSDs as long as the SSDs are completely dry.

Hmmm....
2 SSD's, submerged in water, that were previously RAID'ed?
Good luck on getting that data back!

Was it a true "RAID", or are you talking "fusion drive"?

IF the drives seem to check out ok when connected to another computer (even individually), you might be able to install them into a replacement MBP and have them "come right up" for you.
No way to know until you try.

I'd be wondering if there could be internal circuit damage inside the drives that had the potential to damage the MPB. But perphaps that's just me.
As Clint Eastwood said in one of the Dirty Harry movies:
"Do ya feel lucky, punk...?"

Some advice for the future (and yes, I mean it):
DON'T use RAID for your internal drive setup.
DON'T take a MacBook near a filled tub.
DO learn something about the concept of "backing up" your data.

Go forth, from this day and learn -- a sadder, but wiser man.

I would agree with post #2 that if the SSD's are unlikely that the SSD's will damage your new computer (given the information you've given).

I have a 2012 13" MBP with a RAID 0 setup which is what you probably have. I haven't tried moving it, however the few relatively recent posts on the web indicates that it should work. You should install it internally in the same bays they were in the original computer - it probably doesn't make a difference but it may. I wouldn't try the RAID as external disks.

So I'm currently able to boot the RAID 0 by plugging in the 2 old SSD's through enclosures. How would I take the data from the RAID and put it onto my current internal hard drive(so that all the settings and everything are the same)?

That's interesting that using enclosures works. You can use the Migration Assistant app to transfer data, settings and non-Apple apps to the new drive. If you install the OS on the new drive and as part of the process, the install program will ask if you want to transfer the data, etc. from another source, which can be a connected disk (or disks in your case). If, for some reason, it doesn't see the RAID as part of the install program, you can run it after the install has completed. The Migration Assistant will adjust the applicable settings for the new computer.

If you can get the drives readable "as a RAID", the first thing I'd do is:
1. Get A SINGLE USB3 drive large enough to "hold it all"
2. Use either CarbonCopyCloner or SuperDuper to clone from the RAID to the single drive. Both CCC and SD are FREE to download and use for 30 days, this will cost you nothing.

Now you have your data on a single "known good" drive that you can plug in anywhere -- and go on from there.

You can take that drive and connect it to any brand-new Mac during setup, and migrate your stuff to the new one.
