I recently successfully used the same 750GB hard drive to clone a Samsung 1TB SSD using the Samsung provided software. The plan was to then use this 1TB HGST as a second hard drive installed in the laptop's optical drive bay with a DVD drive bay adapter. This 1TB HGST is recognized by the Window 7 OS and operates fine when installed in the normal hard drive bay and when attached via a USB to SATA cable connector but it is not recognized when installed in the optical drive bay. I previously successfully installed an exact same model NEW HTS721010A9E630 1TB hard drive in the optical drive bay of a different Windows 7 laptop as a second drive with zero problems.
I have tried installing the problem 1TB HGST hard drive using the other optical drive bay adapter, and in the other laptop and still it is not recognized in either optical bay but is recognized in the hard drive bay and with USB-SATA cable adapter. The problem 1TB HGST has relatively low hours, checks out as "healthy", been wiped, surface tested with no bad sectors found, reformatted using Windows 7 and other third party software.

The laptop is a HP Win 7 ProBook 450 G1 (Windows 7 Professional) and the other laptop mentioned is a HP Win 7 G71 345CL (Windows 7 Home Premium)

Does anybody know why this hard drive is not recognized by Windows 7 when installed in the optical drive bay?

How can I get it to be recognized?

Sorry, the following beginning of the post was lost.
A new HTS721010A9E630 1TB hard drive was used to make a clone of a 750 GB hard drive using HDD Raw Copy 1.10 software a year ago.
