I measured the cable and it is aprox. 45cm (18") and it is 80c.
It has also 3 connectors, two of them are in use (on the ends), and
one is free (in the middle). I also checked the connections on
motherboard and on disk, they are both ok.

Forgot one think!
When I recompiled the kernel with DMA support I got speed on HDD only
16Mb/sec according to hdparm.
