which version of red hat could be installed on sata hard disk
 

i dont know which version of red hat linux could be successfully installed on system having sata hard disk plzzzzzz help also from where to down load that version of red hat

Any modern distribution can be installed on a SATA drive.

Any version of Red Hat will install to a sata drive. But, Red Hat is commercial software which you get from the Red Hat website. Get Fedora instead; it's Red Hat (minus some third-party software that can't be included in Fedora) and it's free.

Centos is RedHat Enterprise Linux (RHel) with the logos removed. It runs RHel binaries as well. It is free to download and has a five year support life. Any book written for RH works for Centos. The current release version is 5.1. If you go with any version prior to 5.0 you have about a 1/3 chance of sata being supported directly from the CD(it can be done just with more effort). Fedora is fine (current supported version are F7 and F8) but you only have support for about one year, after that there are no more official updates.
