WL13: ...what's the difference of using them compared to standard HDD things? And how do u use them?
juha: Just to be a pendant, it's AHCI or Advanced Host Controller Interface, and not AHCP. :)
I don't believe you need to reformat your hard drive if you enable AHCI...
Cheers for that Juha, I'm always getting that mixed up ... (it's PEDANT by the way, not PENDANT. Pendant is one of those cables that light bulbs sometimes hang from. Now it's me being a pedant ).
I have a SATA HDD formatted under AHCI and it's unreadable if I set the BIOS back to IDE Emulation.
I knew this when I chose to go with AHCI, but figured it was worth it as I can simply plug on another HDD to increase capacity or performance in future, without needing to use a C: and a D: drive i.e. one BIG partition.
