probably just need to blow away your partition table
dd if=/dev/zero of=/dev/<blk device of your card> bs=512 count=1
then go back and set it up however you need for what ever it is you're trying to do.
Thanks for the link. I got it downloaded and installed with no problems. I ran the bench mark suite twice, one was a little faster than before and the other was a little slower. So yup, no difference in performance.
I bought a 840 pro 128gig (MZ-TPD128, MZ-7PD128BW). I've been fairly pleased with it, though I'm not getting what it can deliver with my setup:
Gigabyte EP45T-UD3LR / 12GiB DDR3 1333 / Core2Quad (Q8300 @ 2.5GHz) / Win 7 64
The SATA interface is SATA II.
Got the drive in the first SATA...
