SATA and SATA II interface

It's silly question, but haven't seen SATA II yet.
Is there any physical difference between SATA and SATAII
connectors? Is SATA cable compatible with SATAII?

TIA

Theoretically, SATA 3.0 (SATA II) and SATA are fully compatible with each
other. The cables, in particular, are the same. However, there are some
documented cases where certain devices don't like to talk to each other.
ESATA has different physical connectors designed mainly to keep them plugged
in, shielded, and give the cables a longer reach. Here's a link:

Thank you David,
If I understand well SATAII hard Drive can be attached to SATA
connector on main board?

Yes. It should just transfer data at SATA speeds instead of SATA 3.0
speeds. Again, I've read that some drives DO have trouble with this. If it
does, I believe there's usually a jumper somewhere to manually put the drive
in SATA 1.5 (original SATA) mode. Check the drive manufacturer's web site.

I've also had SATA II drives default jumpering to SATA, so they won't
function at SATAII levels under the jumper is removed.

Thanks - that explains entirely some problems which I read about
earlier.
