I have GA-K8NS (rev. 2.0) motherboard that has 2 sata connectors but i don't know if it supports sata2/300 discs (it says only that it supports sata)

Nforce 3 chipset boards (like yours) should support SATA II mode, however it depends how old the board is, some older ones won't. Nforce 3 was replaced with Nforce 4 (which to all intents and purposes is the same thing with revisions). Nforce 4 Ultra chipset boards do support SATA II, normal NForce 4 chipset boards don't.

Even if it turns out your board doesn't like SATA II, it should be possible to move a jumper on the hard drive to get it running in normal SATA I mode. The differences are purely hypothetical maximums and you won't notice the difference in a real world environment.
