New hard drive freezes, unable to run properly

hi mayer!

i did that when i changed the hard drive !! how do i know if the vents are working fine!!

If you're running to hot you may need to tear it down and replace the thermal paste. MacBook Pro 15" Core 2 Duo Model A1211 Heat Sink Replacement

Mayer, On the most part I do agree with you! Many a time clogged heat exchanger grills and fans do cause heat buildup as well as old/crappy thermo paste. But, when someone upgrades their HD without addressing the SATA speed issue, other things are going on under the hood here that often cause system overheating and sporadic problems like this. As an example: The OS needs to re-index when lots of files are transferred back to the replacement drive from a back up (the queue is often quite large). In this case the failure to read/write the data causes the drive to retry a few times for each block constantly making the drive and the CPU work harder, hence the system wide heat buildup. If you hadn't copied back any files you wouldn't have noticed the problem.

hi guys it seams that the firmware EFI its upgrade to the last version. apparently for macbook pros 3,1 like mine the sata interface mother boarth chip ICH8-M AHCI can handle only 1.5gbit ;( the firmaware update for this chip wasnt supported by apple, and the hard drive its set to 3.0gbits, so thats whats apparently causing the problems.

the guys at seagate told me to contact the company that sold me the hard drive, to get a jumper for my disc. they also told me if this dont work i should check the compatibility list of hardware of my computer.

so i hope here i can get them. they alos gabe me this map for the jumper
