The issue with the B2 stepping is that over time the drive data would start to be corrupted. The problem has nothing to do with a drive being lost or the system not seeing a drive http://www.intel.com/Consumer/Products/Processors/chipset.htm for more information or check with your motherboard manufacturer.
Try plugging the drive into a different port is the best advice that I can give you.

Yeah, that happened to me too. Congrats, you have the defect.
Did you fix it? or did you get a new motherboard? Was it the same motherboard?
Have you verified that the drives which don't work on that board work on another board? Have you tried testing the drives on any of the SATA 6G ports?
Thanks. That's good to know. I already tried all Sata II Ports, and none of them work. They are not disabled in the bios either (I don't think you can disable them anyways). I might try looking for a new Bios version...

so is my p6x58d-e affected by this also?
i could never get my c300 recognized by the sata3 ports, tried EVERYTHING
been using the drive on the sata2 ports the last year or so
X58 is not Sandy Bridge, so no. The problem you're having is related to the Marvell SATA 6Gb/s controller. I remember seeing posts on several forums related to Marvell and C300 incompatibilities. Gigabyte apparently released a BIOS update with an updated firmware for the Marvell chip. I would assume that Asus got the updated firmware too. Check their site for a newer BIOS.so is my p6x58d-e affected by this also?
