i was thinking if i should wait until Leopard comes out to to install my new 250gb hard drive (Western Digital Scorpio) or to install it straight away and test out the drive first. i still have my 120gb toshiba hard drive that came with the macbook which is running relativity alright but sometimes feel that the harddrive is struggling with occasional pauses (can hear it) etc. i'd probably sell it if i do go ahead and install my new hard disk. any suggestions? should i wait or should i just go for it and install it?
