Re: [gentoo-user] the new ssd, is it happy?

Super obvious question... but can you enable AHCI mode for your SATA
Controller - in the BIOS.

Are you using HP supplied SATA cables - because these may be sucky crap. If
so I would try replacing them - especially if they don't have latches on
the plugs.

I think this is the specification for your motherboard chipset:

So you probably need the decent SATA 3G (6Gbit) cables to get the best
support for your SSD.

I've had some issues with 6Gbit SATA... Basically you are looking at really
high switching speeds - where connector quality makes a huge difference. It
might even be worth cleaning out your SATA connectors with isopropyl
alcohol (99%).
