I just installed a 256gb ssd drive (from OWC) into my 2007 Santa Rosa 2.4 core 2 duo 17" macbook pro. I had done a clone from my old hard drive (7200rpm 320gb) while it was still in the mbp to the ssd drive in an external enclosure using Superduper. It all worked correctly and then I replaced the mbp hard drive with the new ssd drive already installed with my cloned system and the computer worked normally, except for a very slow start time. From the moment of pressing the on button to the screen with the apple is 35-40 seconds every time. It goes from off to the gray screen almost immediately but it stays there a long time before changing to the screen with the apple. This is significantly longer than it was before. I did all of the usual stuff like repairing permissions and running Onyx to clean out any possible conflicts, but the condition persists. Once up and running, programs are loading about 3 times faster and everything is great, but I suspect that there must be some glitch at the very startup with the programming expecting something and having to find a replacement. Would resetting the pram or something be useful? Should I look for some firmware solution? I am loathe to wipe the hard drive clean and start from scratch since some of my programs take hours to install. Thanks for any advice.
