I found a skip with some computer junk and took home this broken SUN server thingy. Pulled it apart and found two hard drives in it.

This is the model of them: Seagate ST31200WC

They have a long thin black data connector (80pin??) and no power plug.

They also have this little board that connects to them and has a molex power connector and a wire (plugged in) which leads to a 50pin SCSI connector.

Anyway, i tried powering them up, the HDD led's light up but the hard drives are not spinning up.

Is this cause they are broken or what ?

SCSI hard drives might not spin up if they are not connected to a SCSI bus. Some drives have jumpers where you can set that.
 
If you have a server with many drives in it, you don't want them all spinning up at the same time when power is turned on. The HDDs will wait until the controller tells them to spin up, so it can spin them up one by one.
 
there should be a motor enable or spindle enable (ME) jumper on either the SCA (80-pin black connector thingy) to 50 pin adapter, or the mainboard of the drive itself. Add it :P
