I have an Opti 210L with Windows XP Pro SP3.  Boot drive is a 40 Gb SATA.  I have added a 1 TB Seagate SATA (not eSATA) to the remaining SATA data connector and SATA power connector.

The OS cannot detect the 1 Tb SATA drive.  I haven't determined if this is a BIOS issue.  Could the 2nd SATA be turned off somewhere in the BIOS? I know on some systems you can selectively change which SATA drive to boot from...but this isn't detecting it at all.

FWIW, I can take each of the 1 Tb SATA drives (I have 3 of them to test) and drop them in a SATA dock to USB connector and have it initialized in XP as well as formatted with a drive letter via Computer Management.

Any ideas?
