This may be a remote possibility because it happened to me long ago but, were these disks used for something else previously? I had a situation where something "special" a program did on the disk caused Linux to not recognize the drive. In that case I was able to use the manufacturer's "restore the drive to its original condition" program to remove the problem. I've also seen other situations where using dd to write zeros to the first 10K or so of the drive got around problems (if the drive is even recognized...). If this is your situation and the manufacturer doesn't offer a "restore..." program you might try other distros' "leading edge" Live CDs to hopefully detect the drive and do something with it then install CentOS.

My labtop has two hard drives : - A 256Go SSD - A standard 1 To hard drive None of the two hard drives are detected by the Centos installer consequently i can't proceed with the installation. If i try with a Fedora server distro, then the standard hard drive is detected, the SSD one is still not detected. I do prefer to install Centos as is is the closed Linux version from RHEL, so what can i do to solve the issue ?
