Substituting one drive or both always produces the same result - failure to see the new drive or drives. Adaptec also confirmed that neither the speed difference nor the throughput capacity of 12bBit of the new drive versus the controller's lower capability of 6gBit would prevent the drives from being used. This lead to an update of the controller firmware, the Windows driver and installation of MaxView web-based interface.

Seagate now basically argues to get 15K drives to match what is there now, which is entirely missing the point.Īdaptec/Microsemi offered much more constructive input. Same result: the controller will not recognize them but I still perceive they are not actually spinning up, so, of course, the controller will not see them. These drives appear not to spin up at all Seagate accepted this and replaced them. > Seagate 21/2” 600GB Enterprise Performance SAS 12Gbs 10K RPM drives.

With the 300GB drives creating SMART errors, I bought two Always used Seagate drives and never had any problems. This is my third Tyan server board and about the fourth generation of Adaptec controller I am using. Having used the first SCSI drive of 20MB on an Amiga computer, I am now using a Tyan server board with an Adaptec/Microsemi RAID 6805E SAS controller and two Seagate 15K Cheetah 300GB SAS drives.
