Thanks for your input! Good, sound, advice all! Luckily, all I'll need to transfer will be a small bracket to secure the drive into the chassis... It's surely a big comfort to hear all the high regards for the 7590A drive. I wish I'd picked it first...:doh: I think it'll be an awesome drive for me. While I've owned many PC's, built most myself, all by myself, this, my first laptop, has forced me to seek advice from others... I have to say that this group is very kind and so willing to help. I'm SO glad I found you all... This ODD matter had me tugging the hair from my head! I'm feeling much better now!
