SSD is not recognised with the internal SATA cable (13" 2010 MBP)

It's pretty weird, seeing that HDD's are recognisable, and that SSD works when in an enclosure (Crucial M500).

I've read somewhere that it could be an issue with the cable, but I bought a replacement cable, and it doesn't recognise the SSD either.

One idea that I have might be the issue is that the SSD needs 1.7 A of current, while the HDD I tested it with only 1 A.
