Bug 1174274

Description of problem:
When I tried installing Fedora 21 on a desktop computer with two HDD and one SSD, anaconda crashed. I dig in the logs and found out that Fedora thought that one of my HDD had a bad partition. The problem is that I did not intend to install Fedora on that HDD, but on the SSD which was fine. After I disconnected the two HDD then Fedora installed without issues. After I installed Fedora I connected the two HDDs back and Fedora was able to mount all partitions on those HDDs just fine. So I think Fedora incorrectly thought that one of the HDDs was bad. Also I installed Suse on the same computer and same SDD and it installed without issues. 

How reproducible:
Try to install Fedora on a computer with at least two internal disks (at least one of the disks in a valid state and at least one disk in an invalid state).

Actual results:
Could not install Fedora on a valid disk when it detects that there is at least one other invalid disks present.

Expected results:
I expect Fedora to correctly assess the valid/invalid state of a disk. But even in the case where there is a bad disk, I expect Fedora to ignore that disk and allow me to install it on the valid disk if at least one valid disk is present.

Additional info:
Not sure if this is useful but the Fedora install was performed on existing traditional partitions on the SDD (no LVM, no swap, just "/" and "/home").
