Windows on SSD. Slower, takes double the time to boot/load if I have a HDD attached. Why?

Samsung 840 Series 250GB 2.5 inch SATA SSD
Seagate Barracuda 7200 2TB Hard Drive
i5 3570k
AsRock Z77 Extreme4 Motherboard
LiteOn IHAS124-04 24x SATA Half Height Internal DVDRW Drive
G Skill RipjawX Series 8GB RAM 1600MHz
2GB Gigabyte GTX 670 Windforce 3X

Not the first time this question has been asked here. Here are the proposed solutions I have found here and elsewhere so far:

- for storage configuration in BIOS, use AHCI, not IDE - CHECK
- make sure only the SSD is in the boot priority list. Disable 2nd, 3rd etc - CHECK
- turn off indexing on the HDD - makes no difference
- make sure there are no (startup) programs on the HDD - CHECK
- ensure drive(s) are plugged into their proper slots on mobo - CHECK. SATA3 connections used.
- make sure there no files on the HDD which the programs installed on the SSD rely upon - I'm not sure how to find a list of such files. Someone mentioned going through the registry...but that's a labyrinth no?

I suspect windows is scanning the second drive for something...but how to discover what it is and stop it?

Any other ideas people? For the last 9 months I've been subjecting myself to boot/load times on 30-50 seconds thinking that was normal :( Booting without a HDD takes ~ 20 seconds.

Discovered when I was diagnosing another problem (to which the fix was, update the BIOS...)

  1. Was the hard drive connected when you put the os on the ssd? If so, that is a known issue and I would suggest a clean install without the mechanical drive connected.
  2. Are you counting the start up from when you press the power button or the second that the windows flag appears? When people state the really fast times, they are starting from when the flag appears. Also the ~7 seconds boot is done without any peripherals and VERY MINIMAL drivers upon startup. With that being said, it is unusual to have the boot time be extended with an HDD if the OS is on the SSD. I had the same issue, and it was because my HDD had been plugged in when installing my OS. A simple reinstall (and I took the chance to upgrade to 8.1) fixed the issue for me.
  3. Clean install on the SSD without the HDD connected. I had the same issue on my system when installing Windows 7. Interestingly, Windows 8 (8.1) does not show this behavior.
