What mainboard are you using?
Which ports are the drives attached to? (ie: SATA ports for standard chipset, or SATA ports for 3rd party RAID chipset, etc)
In my now dead computer, the two drives that I am attempting to use for general backup (individually), were in a RAID 0, using the SATA RAID chip on my Abit iC7 mb. I do not need any data off the drives, I just want to wipe them and reuse, via the Star Tech hard drive dock connected via the eSATA port on my Vaio laptop.
