Yep, this is what I get for not double-checking things BEFORE I buy the new drive and take things apart to install it. Duh... Thought I was outsmarting myself by buying a 500 GB Seagate 7200 rpm SATA drive with 16 MB of cache so that I could install Win 7 on the older laptop. I never thought of it having an EIDE HDD. Guess I'll start over... argggghh Wanna kill these ads? We can help!
