Thank you for your help.  Sorry I am not sure what the problem actually was.


Drive bays in PC cases are notorious for causing drive detection problems. I avoid them completely.

Your board has only two Intel SATA III ports, the other four Intel SATA ports are SATA II.

The ASMedia "SATA III" ports are really SATA II½, not a real standard but given the speed they are capable of providing, they are clearly behind the Intel SATA III ports in speed.

But the concern about whether or not an HDD is connected to SATA III or SATA II is a waste of time. The only SATA III speed in ALL HDDs is the connection into the drive's buffer memory chip. The number of HDDs that can saturate SATA II bandwidth is zero.

SATA III HDDs are pure marketing BS, nothing less, sorry to say.

The BIOS or Windows Device Manager.

Does your removable use a sled or is it sled-less? Odd's are it just wasn't making proper data contact, regardless, as you implied it was spinning. It's working now and that's what counts.

There's a few possible things that may be at play here.

Sata port SATA3_A1 is shared with eSATA3

In the BIOS have you disabled the ASMedia SATA3 controller? Note: For best performance of that 2TB drive connect it to the Intel controllers, not the ones that end in SATA3_Ax. That A signifies an ASMedia port. Try CD/DVD/BD drives on the ASMedia ones to relieve and free up the much faster Intel SATA3 ports. All CD/DVD/BD drives that I'm aware still only operate at SATA1 speeds and the ASMedia ports CAN keep up at that speed/interface.

Replace the SATA data(not power) cable used on the 2TB drive.


Post back your results please.

Hello. I have had this system running for some time now with and 230 GB SSD and windows 7 64 Bit and SATA blue ray drive.  I was always going to add a larger SATA hard drive when i had the money.  I have purchased a brand new Seagate 2TB SATA HD when I connect it to the system the bios does not detect the hard drive.  It sounds like it is spinning but obviously if the bios does not detect it neither will windows.  I do not have another system to test the hard drive on at this time but it is brand new and not a used one.  Any help appreciated.
  Thank you
