Hey everyone, Just wondering if anyone with a mid-2009 13" Macbook Pro replaced their HDD cable (Part No. 821-0814/922-9062) to address the freezing/beach ball issues that come with using an after-market HDD (i.e WD Blue/Black) and EFI 1.7? (also known as the well documented SATA 3.0/1.5 interface issue) I'm currently on SL 10.6.8 and EFI 1.6 (had to downgrade right after going to 1.7) so that I can run my WD Blue WD5000BEVT without freezing/beach balling. However, I'd like to upgrade to Mavericks, but that requires me to upgrade the EFI to 1.7 - hence the dilemma. I was looking at grabbing this replacement: http://www.ifixit.com/Store/Mac/MacBook-Pro-13-Inch-Unibody-Model-A1278-Mid-2009-Mid-2010-Hard-Drive-Cable/IF163-013 Has that worked for anyone? Hopefully some others can chime in before I spend the $50/$70 to see if it'll work for me... Thanks for any insight!
