Re: ASRock SATA-3 controller
What is the Chipset of your M/B?
Could you please provide the model name of your M/B?
About your question "how do I update the card from version 10 to 34", it should be the driver version.
You can see there are two driver version on ASRock website, each driver version has floppy image and SATA3 driver.
Floppy image is using on OS installation, another one is using under OS.
I have tested the Crucial C300 SSD with ASRock SATA3 card, I didn't see your same issue on Intel P45 chipset M/B like yours.
Please change another SATA cable then try again.
