Hello. I have a Macbook (Late 2006 I believe). The specs are: 1.83ghz 512mb ram and 60gb hd. I have already upgraded the ram to 2gb and definitely need a bigger hard drive! I think I can upgrade this myself but I have a few questions. These are the two drives I am looking at. Is either of them better than the other? http://eshop.macsales.com/item/Seagate/ST9500325AS/ http://eshop.macsales.com/item/Western Digital/WD5000BEVT/ When formatting the drive can you use the original tiger install disks or do you have to buy a full new copy of osx? Unfortunately one of my install disks went through the washer and i am DOUBTING it will not work anymore. Can you order new ones from 1 800 my apple? Does anybody have any tips for formatting and is the guide on apple fine? And a few questions about ram: I keep hearing different things about the max amount of ram in my macbook. Some websites say 3 and some say 2. Which is true? I had 2.25 gigs in mine at one point the system profiler recognized it but the computer would just restart whenever i put it to sleep. After about 2 weeks it would not start up or charge at all so i just took out the 256 mb and kept it at 2. Now i find myself using most of the ram and was wondering if you could put more ram in and maybe I did something wrong. Thanks for any help!
