Silly sata problem
 

I just bought a new large 250G HD and a PCI card(see lspci below) to control it for my mythtv box.

I'm using FC2 with the kernel 2.6.10-1.771_FC2

It seems like linux sees the hard drive but I can't format it when I do a
$fdisk /dev/sda

I get a

Unable to open /dev/sda

The dmesg output makes me think that the new hard disk is on /dev/sda. Is this totally wrong? What should I look at to see where it is located?

Should I just upgrade the kernel and try again?

I've tried that and it didn't work. Thanks though.
