Dear Mr. Craig:

Yes, fdisk seems to see both 1 TB drives:

Dear Helpers:

I have installed two 1 TB Hard Drives in my new system.  Only one of the two is
recognized by Fedora.

They are WD1002FAEX drives.  When I asked Western Digital for assistance, their
"help" wasn't much help.

They reported this difficulty was the result of a "Signature Collision".  Then,. they gave me instructions on how to clear the error in Windows XP, Windows Vista, Windows 7, and Windows 8.  None of those is going to work under Fedora.

Does anyone have any ideas on how to fix this?

Thanks,
