Please post back a camera snap of the installer Drive Map. If the 32 gb shows up then you may have the option to install your OS and some of your programs there, with the lesser-used Programs and User data folders installed to the HD's.

Putting together what we've learned with the important new piece Bob found, it's looking like the PC is sold with HD's raided with a 32gb SSD caching chip on the mobo. Whether Win7 can be installed to the chip now that they're unRAIDed remains to be seen.

But if the 32gb is showing up as a choice during install then it's worth a try to see if you can get the OS and your most-used Programs on the SSD.

Well done, Jim. Congratulations for getting it working.

I'm assuming disk 1 is the SSD.

I was just curious which drive I should choose for the clean install. And if it is still advisable to do a wipe of the drive.

I'm also curious to know if now that it is not RAID'ed if I could actually use it as a secondary drive.

Info from the The Definitive Guide to Clean Install OS on a mSSD Cache Equipped Laptop (dv6t-7000, dv7t-7000, Envy17-3200) link on how to make the mSATA SSD usable as a separate drive.

3. Under the “Accelerate” tab, select “Disable acceleration”. (see attached screenshot)
4. After step 3, you should see a new option “Make available” on the same tab. Click on that, now you have completely disassociated the mSSD from the cached drive. Restart computer.
5. (Optional) Reformat the mSSD in Windows’s Disk Management (type in Disk Management in start menu). When prompted, choose MBR as the initialization type. Now you can use the mSSD as a drive. (see attached screenshot)

You should be able to follow step #5, the mSATA SSD is showing up in your Disk Management.

From looking for info on this subject, there was mention that you need to install the Intel RST driver from the HP site and not from the Intel site.
The newer Intel RST driver has been causing BSoDs for some.
