Specialized storage devices are NAS or other remote storage array types of devices. So that is not a valid option on your stand-alone system. It looks like your hard drives are visible to the Linux Anaconda installer, but you may want to check BIOS configuration and verify that they are configured correctly there. Unplug the power connectors to the drives and reseat them, and data cables from both ends and reseat those as well. Ensure that the jumpers on these parallel ATA drives aer set soi one is "Master" and one is "Slave." Other options may work, but also may not. The "CS" option is to be avoided. Be certain that the Master is the drive you want to be /dev/sda and the Slave will be /dev/sdb. Based on my experience the jumpers on the hard drives are the most likely cause of this problem. AFAIK, there are no "special" steps to install CentOS on any particular local hard drive. So long as BIOS and jumpers are correct, it should "just install."
