"The disk may fail soon" on two others Hard Disks

I'm trying to install Windows 7 Proffesional x64.
I have this same fail when i'm choosing two others hard disks: "Windows cannot be installed to this disk. The disk may fail soon. If other hard disks are available, install Windows to another location."
1st disk - WD 160 GB
2nd disk - WD 40 GB
