what exactly do you mean? Connect a SATA-2 harddisk to a controller that supports SATA-1 only?
Yes, that's okay. All SATA revisions are compatible among each other. That's part of the standard.

Look at USB, it's quite the same there: You can connect a USB2.0 device to a USB1.1-only host and vice versa, only you won't get high-speed, of course.

In theory, yeah, a SATAII HDD on a SATAI controller should be fine.

In pratice, its mostly true, but not always. By far the worst AFAIK is nForce SATAI ports.

The following compatibility problems for Maxtor SATA II hard drives with the nVidia nForce4 controller have been identified:

Data Corruption: If you have problems with corrupt data, the problem lies not in the firmware used. Please go to nVidia's website to get the latest nVidia chipset drivers.

No Detection: If you have problems when booting with a Maxtor SATA II hard drive connected to an nForce4 controller.

Note: The following does not apply if your disk is not connected to a nForce4 controller, such as SiiG (Silicon Image), HighPoint, Promise etc.

BTW, the nForce3/4 SATAI controllers were awful. Most (all? I'm not 100% sure) dont support AHCI, or NCQ.

At least some SATAII HDDs have a jumprer to force the HDDback to SATAI.

what does a graphics adapter have to do with SATA?

Right you are, I remember reading about that, too.

nForce is the nVidia chipset name, not the graphics chip/GPU.

thank you, I didn't know nVidia is making other things beside GPUs and graphics accessories.

Not much anymore. Intel dropped nVidias license for making chipsets some time ago, when intel and nVidia were busy sueing each other-

AMD hasnt stopped nVidia making AMD chipsets, but nVidia hasnt realsed any new chipsets for years. The last nForce chipset that came out was the 980a, in 2009. Which just a rebranded 780a from 2008 (updated for AM3 socket and DDR3 to suit).
