Good morning all. I have searched the site and the web but can't find my help for my issue. I have a 2006-2007 Mac Book Pro and I was looking to upgrade my HD since it is giving me issues now. I've loaded my OS on it three times and its just not having it anymore. My question is, whats my upgrade options for an older model mac book pro? The hard drive I have is: Hard Drive 065-6623 120GB Serial ATA Drive@5400rpm What can I upgrade to now? Thanks for any and all the help.
