HDD Error: The request could not be performed because of an I/O device error

Hi

I recently upgraded to W7. I installed W7 first on the SSD. Once the operating system was running I then proceeded to add the internal HDD (500G Seagate).

In Device Manager->Disk Drives:
Drive 1: W7 sits on my 64G SSD and has the location 1 (1).
Drive 2: The 2nd drive is a 500G HD that has the location 0 (0). The drop down box of Device Usage shows: "Use this device (enable)"

I went to the Disk Management but:
a) only the Disk 1 is showing
b) it is does not appear to be seeing the 2nd disk

I went into Computer Management and tried to enable the Disk. Unfortunately it has come up with "The request could ot be performed because of an I/O device error"

The HD is an intertnal HD with Sata connectors.

1) I changed the Sata ports but still no difference
2) WIndows says the drivers have loaded correctly and the device can be used
3) I ran the Trouble Shooter but no issues were found.
4)The same issues as above are occurring. Please see images below:

Low level format the drive with any of the free tools available to do so.

Thanks. I downloaded the free tool. The tool picked up both drive but when I went to format the drive i get the error below (see attachment)

And the drive is getting power for sure?

Use Active software low level format tool in dos mode by booting to it.

I re-connected the the drivers power and I could definitely hear the drive start up.

Do you have a url re the "active software" you mentioned. Thanks for the help.
