I am planning to upgrade the stock hard drive of a Mid 2009 Macbook pro (15 inch) to a newer 1TB one. I have seen a few threads online stating that without replacing the stock SATA cable the system would either not boot or become unstable and result in data corruption.


It seems that the cable included for some systems are not up to spec in terms of quality so when they are paired with newer hard drives it results in data integrity issues.


Can anyone http://www.reddit.com/r/appleconfirm if this is necessary/recommended for upgrading the HDD or is it only an isolated issue? Appreciate any feedback. Thanks.
 
Replaced the HDD in my sisters MBP (same model as yours) without any difficulty or problems. Also have replaced the HDD in my own model (Late 2008, one model older) without problems to a 2012 WD 1TB drive. You should be fine!
