My old hard drive was getting quirky and unstable
Thanks to your instructions and video (I viewed ahead of time), including the tools I bought with the drive, I found it went well.
Don't be afraid to dig in. And when you finally get to the old hard drive, remember to look for the black plastic latch - press it to remove the old drive - THEN you can remove the drive screws. It took me awhile to figure that part out. ALso buy the #6 and #8 drivers if you do not have them already.
