Hi Guys, I am new here, finally bit the bullet and signed up. I have heard that this is a great and very informative knowledge base. I have an existing small home server and am running out of space (and SATA ports) so I have done a bit of reading up and purchased an Adaptec 51645 from the US. I also purchased 3x Seagate 3TB drives (ST3000DM001) after checking the compatability list for the card. I have installed them and am having trouble with the drives talking to the card. All cables are seated correctly, drives are powered, I can access the card setup menu after POST without issues but even when I rescan for drives nothing is found. I downloaded Adaptec Storage Manager and couldn't see any drives in there either so I proceeded to update the card firmware to the latest version and attached the drives directly to the motherboard and updated their firmware as well (Drives were visible and worked when attached to an onboard SATA port). Still cannot see them when attached to the card. I have no other ideas, anything else I can try? Is anybody else here running the same card with Seagate drives successfully?
