I have a Mid-2010 17" MBP running 10.8.2. Lately I've been getting LOADS of spinning beach balls when I try to do ANYTHING, it's making the Mac practically unusable. I downloaded Rember and tested the RAM, came back fine. I've now bough something called SMART Utility to test the hard drive, and it's said "Drive Failing". The items in red are "Reallocated Sector Count" and "Reallocated Event Count", overall SMART status "FAILING". The drive is a 1TB Toshiba that I bought brand new at the same time as the Mac and fitted myself. IIRC because I have a 17" MBP, I can get the wider internal drives? Anyone recommend a decent, cheap, at least 1TB drive that will fit my MBP? Thanks!
