Hi guys, i just bought a new uMBP 15 2.53 last night and i bought a Seagate 500GB 5400rpm HDD to replace the one on board. I installed the HDD and SnowLeopard install went through great but after install every time i boot up, it takes a long time on spinning gear. It eventually loads up but takes a while, I ran Repair Disk Permission and Verify disk and everything turns out fine. I even ran Apple hardware test on HDD and tests passes. I haven't installed 1.7 EFI Firmware since i've read that it doesn't work so well with third party HDD or doesn't work at all. Any suggestions?
