Hi My sister's got a core duo first gen macbook with a 60/80gig hard drive(I can't remember which). I'm looking to replace the drive with a WD Scorpio Blue since it's got a few good reviews-but would it fit inside the Macbook? I've read that there are 12mm & 9mm drives. Also, what's the biggest hard drive I can put in there? from my research done via google it seems there is no limit as the mac has EFI instead of bios. Thanks UPDATE: I am looking to send this email to email@example.com.....I would like you guys to first look at it: Dear Sir, I am writing to express my dissatisfaction with the Repair Service in Hong Kong. Unfortunately there is no emaill address for support issues and the applecare hotline in Hong Kong is not very helpful at all, so I have no choice but to email you directly. I apologise for any inconvenience caused. I have a first generation Core Duo Macbook White (Serial: ) that has developed various hairline cracks, identical to the many cases reported on the world wide web. I took it to 'CASE' (An authorized service provider in Hong Kong), and they only replaced the palm rest area. I suspect this is due to a communication problem due staff's poor level of english at the centre. On the repair receipt, 'headline crash' was noted as one of the problems. The meaning of 'headline crash', I am afraid, is beyond my knowledge. I was told by another member of staff, when I picked up the machine, the other areas were not covered as they were considered 'damage due to neglect by the user' but I think otherwise. I suspect the engineer who undertook the repair also failed to understand the meaning of the phrase and did not perform a full inspection, and hence did not know about the presence of the cracks as they are quite fine and can be diffcult to spot at a glance. The machine has NEVER been dropped, and the only visible damage to the machine casing are various shallow scratches as a result of everyday wear and tear - there are no dents on the machine. I would like to use this opportunity to show you some pictures of the cracks. I have personally checked the links and they are completely safe; the pictures are hosted on google's picasa picture service. 1) Bottom Left corner of screen bezel: http://picasaweb.google.com/lh/photo/CA0lNqDuXrFk93WQBFZWAA?feat=directlink http://picasaweb.google.com/lh/photo/CA0lNqDuXrFk93WQBFZWAA?feat=directlink As you can see the corner is chipped; this damage, I suspect, is due to a design or assembly flaw. That particular corner comes into contact with its counterpart on the palm rest part every time the machine is opened and closed which puts stress around that area, causing it to eventually crack and break off. Below is a picture of that particular corner from the outside. As you can see in the picture below, the surface is smooth and shiny under the strong lighting and there are NO DENTS to cause the damage on the inside. http://picasaweb.google.com/lh/photo/mXmws6GpZRxzFIlcZh8Rsg?feat=directlink 2) Crack along the hinge on the top casing http://picasaweb.google.com/lh/photo/EeD1fHGXGVGvoTsFqjbaRw?feat=directlink This crack is located at the hinge and runs parallel to the gap. Its length is approximate half of the macbook's width .As a material scientist myself I believe the crack along the hinge will almost certainly propagate to the point where it will split the casing into two, fall off and become unusable. 3) Crack near air vents. http://lh3.ggpht.com/_YTZTlm919og/SlBiaDmK91I/AAAAAAAAF6M/5kPYzQq3OBo/s720/P1140687.JPG http://picasaweb.google.com/lh/photo/UfYd3R0C2bFzEIVRB4ElaA?feat=directlink There are two separate cracks, one of which propagated from one of the stress concentrators i.e. a corner where cracks are most likely to propagate (not shown in the pictures). This may not be a design flaw as the corner is rounded to minimize this effect, but it is a matter of poor material choice. 4) Poor refitting of the palmrest area - NEW CRACK AFTER 2 WEEKS I applied a Moshi palmguard to protect the palm rest after I got the machine back. To my horror, there was a huge 1mm gap between the palmrest and the casing after about a week of use that I did not manage to spot when I collected my machine. http://picasaweb.google.com/lh/photo/gR9rGTFOUrBsclPEHqkvYg?feat=directlink Unfortunately due to the poor refitting a new crack has developed at the side of the palmrest: http://picasaweb.google.com/lh/photo/AoKY5dCJO34-S1G-5O3XPQ?feat=directlink http://picasaweb.google.com/lh/photo/AMF5GPc1jCu9aiZWFwtMFQ?feat=directlink I have applied a little pressure to side very carefully by using a towel between my hand and the computer to ensure there was no excessive force to worsen the crack. The gap has now closed up, and I have also done some cleaning; the crack is somewhat less visible but it is still there. I define myself as a somewhat loyal customer; I've bought 5 iPods and 2 Macs for various members of my family over the last 3 years. This experience with the repair service will, unfortunately, lead me to reconsider my shopping habits unless it is resolved. If I were located in America or the United Kingdom, the issue with the cracks would be solved right away at Apple stores, acclaimed for their level of customer service. As I am located in Hong Kong, I do not get the privilege of visiting a friendly Apple Store. I am just disappointed with the level of service I get in Hong Kong compared to those overseas. I look forward to hearing from you soon.
