Question: Will this work with a 2009 MacBook Pro Hard Drive? I didn't see any reviews for macs and I want to transfer my data to my wife's computer. Thanks!
Document: I purchased this product to transfer files from my wife's failed PC to her new MacBook. Process worked great and I was able to recover all of her files from her old hard drive , using the hard drive enclosure I purchased. I highly reccomend the product to anyone needs to able to do the same."
I bought this to clone a HD replacement I bought for my MacBook and to house my old drive. The process was easy except that the screws to hold the drive in the case are truly miniscule. Make sure to work someplace where you can see things if you drop them. (The screwdriver is provided.) I was concerned because the stated capacity for drives it can hold is 120 GB but I put a 160 GB drive in it without issue.
I finally got this to work. Replaced my PS3 60GB HDD with a WD Scorpio Blue 320GB HDD. Put the old 60GB in this enclosure - no problem. At first my pc (Windows XP) did not see the HDD. Looking in "My Computer" - nada. Finally figured it out. Unfortunately you can't just put a drive in the case, plug it in and it will work.
I'll give her the box next time I see her, and she can copy everything to her computer.I presume that this will also give her a spare drive; it seems to work just fine. I suppose that we could just reformat it, and then copy the documents and pictures back onto it, and use it as a backup.I never needed to read instructions, and the entire process worked flawlessly. Highly recommended.
Plugged in the USB cord to my iMac and Bam up popped an error. Too much power was being drawn from the device / cord. So I tried my Macbook Pro. Same error. Then I went to the windows box, same error different wording.I was getting ready to return the thing thinking that it was a bum enclosure. I was looking for another cord that would work high and low. It is a USB to mini-usb cord.
This hard disk enclosure transformed my old hard drive that I took from my MacBook Pro into a portable drive that I can use without external power supply.Simple and cheap.
I upgraded my MacBook Pro with a new 500 GB hard drive. This enclosure was a great way to make use of the old drive as a new portable drive for transferring large files. A useful feature is the small screw that holds the enclosure together to prevent inadvertent separation of the drive from the connector.
It was ok for the price at first. the two tiny little screws are a pain. i use it a lot to transfer from my computer to my PS3. the usb port on it kept getting looser until it snapped off in the inside. its pretty cheap. i take care my things and i was surprised to see this happen. i'd recommend an IMicro 2.5 SATA and IDE combo enclosure. cheap and durable. bought one in a computer store for $23.
I loved this; it houses my old macbook hard drive (80G). Seems to work fine. V. easy; no complaints.
This product worked perfectly. I am not close to being a techie, but I was easily able to recover and save my valuable files from the hard drive of a dead Dell laptop. (Most computer services will charge over $100 for this.) By the way, Dell was miserable to work with (and expensive) in wasting my time and failing to diagnose and repair the relatively new Inspiron laptop I am now planning to ritually (and safely) defenestrate. Go with Apple.
Answer: I used it with my MacBook.  It should be fine if you are going from one Mac to another.
