Trouble with SSD/HDD in Macbook Pro Mid 2009
I have a mid 2009 15" 2.53 GHz MacBook Pro with 8 GB RAM and a 250 GB HDD. Recently, I purchased a WD 1TB 2.5" 5400 hard drive to upgrade. I used SuperDuper! and made a clone of internal drive to new drive via USB. After swapping the two drives, my laptop became very slow. Spinning beach ball appeared very often, almost everywhere. Did extended Apple hardware test, all ok.
Then I put back the original 250 GB HDD in my MacBook Pro and took out the new one and things are fine again.
I found this post with the same problem. Sounds like I am stuck; I can't upgrade my internal HDD?
Has anybody successfully upgraded their HDD? I want to upgrade to SSD, but this time I want to make sure it will work before making a purchase!
