Hi there. Long time lurker but first time poster here. ive read a lot of threads about clicking hard drives... most seem to talk about some stock BTO and wd scorpio hard drives clicking, but i havent found a thread where people posted hard drives that DO NOT click. Im planning on ordering a hard drive soon... was looking at wd scorpio 500gb till i found all those clicking noise threads so now im reconsidering. I thought id start this thread to help myself and others looking at hard drives so please post if you upgraded your hard drive with on the june 09 MBP and your hdd does NOT make clicking noise. let us know what you've upgraded too. For myself, im not really looking for more space but just something with better transfer rate... this stock 160gb is kinda slow and i know there are faster HDDs out there even though they are 5400rpm too.
