I've found a great ext. adapter that provides links for HD, CD an even laptop HDs.. Checkout at http://www.geeks.com th adapter call AD-2020 if i remember right. This can later be used for items so its very useful.
Yes, you can connect the old HD your int. cabling just follow the convention being used, sale&master. But many newer systems use the CS cabling scheme, thus its the only other type available.
My old Dell dimension 2400 (windows xp)took a lightning hit. Our local techie diagnosed the power supply and motherboard were fried. He says he can retrieve our old hard drives data for $100 or so. Being a cheapskate, I'm looking at installing the old hd into a new computer, and recovering the data. I've found sites that describe how to do it with master and slave and jumpers, etc. It looks fairly easy.
I've also seen where people have created more problems for themselves with booting problems, etc.
My new computer is a Dell Vostro, with Windows Vista.
Any advice out there?
