4 TB drive works externally as USB but not internally

This is a follow up to an earlier post: the situation changed and the problem is partially resolved.

System: Dell Studio XPS 9100, Win7 Pro 64 bit. Samsung 840 Pro boot drive.

Ever since I installed my SSD my system will not boot up when I connect my HGST 4 TB data drive internally. My WD Caviar Black 2 TB drive that's connected internally is fine.

If I do an F12 the HGST is shown on the drives list, which rules out a problem with either the SATA port or the cable. But the boot never gets past the Windows screen: it just hangs forever.

As soon as I disconnect the HGST, the system boots normally.

Here is what is weird: The HGST is fine when installed in a Sabrent USB 2.0 case. System boots normally and sees all 4 TB.

To my knowledge all of my SATA drivers are up to date.

Any idea what could be causing this?

I really don't want to have to use this drive externally, but I am completely stumped.
 
It is the 2.2Tb limit problem, you need to format the drive to the GPT format. http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5079632 As long as you format it to GPT then you will be fine because the win7 64bit does support the GPT format. I know some MB manufacturer ( gigabyte, asrock, etc.) has the software called 3TB HDD unclock something like that, but I don't know Dell has it or not, even you can check the HGST website too. http://www.hgst.com/support/faqs
And it works fine in the Sabrent USB 2.0 case because that enclosure supports high capacity (>2.2TB) drives.

I do not think this is related to the 2.2 TB limit at all.

The drive was already initialized as GPT and formatted as 4 TB. I confirmed this is in Disk Management by checking the Partition style in the Volumes tab of the Properties.

I think it is a SATA controller driver issue although both the Dell and Intel sites indicate all my drivers are up to date.

If it were the 2.2 TB limit problem I don't think Windows would see all 4 TB, regardless of the capabilities of the Sabrent enclosure.
