Thanks @Dan for your suggestions. Sorry i did not accept your answer since I solved it myself. From my experience the NVidia SATA controller is not easy to deal with. But that is what the 2009 Mac Mini has. I have no problems with 2008 MacBookPs and 6Gb SSDs. They all autosense capable speed. As it is hard nowadays to find any new 3Gb the conclusion here is that e.g. CRUCIAL SSDs work with the 2009 Mac Mini and NOT the Samsung EVO. At least stay away from Sandforce driven SSDs. The trick with leaving the drive plugged into power-only for some hours is weird but works obviously!

The "problem" is Macs last too long. I doubt I would be plundering with a 2009 Dell laptop...
