Is there an easy way to tell from within Windows whether the HDDs inside a computer are IDE or SATA?

If SATA, is a SATA II drive backwards compatible with SATA I?

Hi, SATA II is backwards compatible with SATA I.

Download and run SIW click here
this will tell you just about everything about your PC, except Power of PSU.

Maybe -

SATA 2 (SATA 300) is not backwards compatible with a SATA (SATA 150) controller. In order to use a SATA 2 drive on a SATA (SATA 1?) controller, the hard drive must have a jumper position to restrict it to using SATA (SATA 150), and a jumper must be installed. Some drives have the jumper position available (e.g. some recent Samsung), some don't (e.g. some recent Maxtor).
This information can also probably be easily found on your hard drive manufacturer's web site.
If your drive does not have the jumper position available, you must return it and get a SATA 2 one that does, or a SATA drive.

Thank you for all the replies.

The SIW program is a very useful utility, especially since it runs without needing to be installed. I now know everything I wanted to know - and more - about my hard drive!
