So yeah, this is the story; ...I bought a new, 500GB 5400rpm Seagate Momentus (ithink) drive. Well then I waited for the delivery of my Torx set of screwdrivers. Then I realised I didn't backup, so I used Carbon Copy Cloner to backup the 80GB to a spare drive. Following that, I installed the HDD without issue, restored all my stuff, and it boots up perfectly. Now the problem: The macbook hangs on the white screen for around 20-30 seconds... Heres the normal boot routine: Power > White screen 1 sec > Apple logo > Blue screen > Login > Done. But instead, now it hangs at that white screen, for 20-30 seconds. The first time i actually thought I didn't install the HDD correctly as it would normally do that if EFI can't find an OS, but then it'll boot no problem after the wait. What's up? I'm on the original 250GB now... And it's not a problem with CCC for sure, because the original was also subject to it after I hated on Lion. So it's pretty much the new 500GB HDD?
