Hi. I've an Asrock K7 Upgrade 880 motherboard which only recognises the current hdd. There are 2 SATA connectors and so I should be able to plug in a 2nd SATA drive. However, not alone will the mobo bios not recognise a 2nd SATA drive, even if I remove the current drive and replace it with a new one, the mobo doesn't recognise it at all. Originally, I thought this was confined to SATA2 (3.0g/s) drives, but even if I replace the current drive with other SATA1 drives, they don't get picked up by the bios. Any reason for this? Thanks.
