Has anyone here done this upgrade yet? Any recomendations on a good HDD? Newegg carries a few 250GB models by Samsung, Western Digital and Hitachi. I've had good luck with WD 3.5" HDD's in the past, but no experience with their notebook drives. I've also located disassembly instructions. Looks a little involving, but confident I can pull it off (I repaired PC laptops for ~7 yrs). Any recomendations or suggestions?
