Likewise for me; I have a mid-2009 MBP, however mine is a 17" not the 15" that everyone else has. In my experience the problem is with all drives that have a transfer rate greater than the original 5400rpm drives that were shipped with this model.
So far I've tried the jumper settings on the hard disk drive (this makes it less stable and more crashy) I've tried a plethora of drives, from Momentus 7200's right through to the 750GB Momentus XT. I've been in touch with Seagate, who are aware of the problem, and claim that the jumper will fix the issues, it does not.
Here is a part of the email from Seagate:
Thank you for sending your Seagate E-mail inquiry.
The issue is you have is not related to the Momentus drive, but rather to Mac incompatibility with such faster and high performance.There is no Jumper that comes with the drive, for further information on how to use the Jumper settings please click on the link below, please keep in mind that the information on the link below is not related to the Momentus drive ,however it just give you an idea how the Jumper looks like and how you may reduce the drive speed :

I also had a conversation with the tech team at Crucial since I was considering upgrading to a full SSD. The guy there told me that if the problem was with the Nvidia chipset (per Seagate's email), then it's unlikely that their SSD would be any better at solving the problem, moreover, the SSD would not have a "step down" jumper to help with the problem.
So now I'm ready to swap the cable for a higher specified aftermarket version, which is the fix that has solved the issue for others, however, if you thought it was difficult trying to find one of these for a 15", try finding one for a 17". There are plenty of "original" cables available out there, but if anyone can help me find an "improved" HDD cable for the A1297 17" Mid-2009 to help solev this problem, I'd be eternally grateful.

Tony.
