The Unfortunate Bottleneck.

I believe this is it, then to a long drawn out battle between my laptop and me. I didn't want to accept it at first, I didn't want to believe that the problem was the drive, but it was. Ever since I made the disk drive upgrade to my Macbook, I was having consistent freezing, disk i/o errors, as well as data underrun error being reported in the console. I would really like to thank Scott and Mike at iFixit for trying their best to help me. They sent me a new caddy, even a new drive adapter. And even though that did not fix the problem, the fact that they made the attempt to fix it really is amazing. They are the best customer service I have ever dealt with in a long time. I had never dealt/bought from iFixit prior to this, but that didn't matter.  No matter what, they were determined to aid me with my issue.

So what was the problem in the end? The problem is that the Caviar Black 7200 RPM I bought was too fast. Simply put, when the data had to be converted from SATA to ATA, the disk would be moving to fast for the computer to handle. This would cause the data to "bottleneck" in the conversion area, thus slowing down my computer. How am I so sure this was the issue? To find out, I took an old 5400 RPM drive that I had, which is failing but still works, and popped it in the bay. I am writing to it, reading from it, and not seeing as many disk i/o errors in my console. There are still a few showing up in the console, but they are not enough to slow the computer down. Because of this, I now have to make another transaction. I will now have to go to Amazon and request an exchange for a slower Caviar Black drive, as well as pay the difference for the drive. This just goes to show that you can't rule out the most obvious option right away.
