Hi everyone, I have been having alot of problems with my MBP lately and I believe I have isolated it down to the HD. Lots of files have become curropt, I can not copy things to other drives due to I/O errors, and I ran TechTools Deluxe and it found over 400 bad sectors. I am planing on taking it to the Apple store later today. Since the SMART status is still verified, will they have any problems replaceing the drive? Assuming I can convince them to replace my dying drive, how long should this take? Can they do HD upgrades in the store, or do they have to ship the computer out?
