Hi, I'm looking to get a Macbook Aluminum 13 inch next week and I have already ordered the following with an intention to upgrade the laptop's hard drive once I have received it: http://www.bestbuy.com/site/olspage...500gb&lp=4&type=product&cp=1&id=1218018140789 A Western Digital Passport 500gb Essential Edition Portable Harddrive. I browsed around for hours and I am a bit skeptical about my hard drive purchase. From what I have read (can't find the link anymore), the encasing contains a 500gb 9.5mm Western Digital Scorpio Blue hard drive (My intention is to extract the harddrive of course). I want to ask those who have upgraded their macbooks with this hard drive if this is true. Another question I would like to ask is if the beeping problem has been fixed for this hard drive. Youtube shows the following: http://uk.youtube.com/results?search_query=WD5000BEVT&search_type= Some other questions: 1. How is the vibration and noise level compared to the Hitachi it came with 2. Cons of the 500gb passport hard drive? 3. Would you choose a different brand and model, like the Seagate Momentus? 4. Any recommendations? Thanks all!
