I Bought an used Toshiba U940. It should come with a 32GB Samsung MZMPC032HBCD SDD, and it kind of did, but it only reports 11 Gb, as you can see here http://oi67.tinypic.com/2k0etl.jpg in windows disk management.

Nothing is installed on it. I downloaded Bootable Mini Tool Partition manager, which runs without launching windows. It does show the whole 32GB space:

I create a primary partition and apply changes:

But, to my surprise, this is what windows shows

Also, its not showing in the available disks when trying to install Windows 8.

I'm honestly out of ideas here.

There should not have been anything to do. It was simple plug and play. I am not certain what effect your partitioning had on the cache. You might want to check the motherboard's system BIOS and see if the drives are still in some sort of RAID array.

Here is a sample explanation from an early 2013 technical review:

"While SSDs are very fast, they are also small and expensive. In order to combine the speed of flash memory with the capacity of a conventional hard drive, several manufacturers use cache solutions. Here, two drives work in a special RAID connection, which automatically moves frequently used programs to the SSD."

"Toshiba use a 640 GB hard drive from Hitachi (Travelstar series, 5.400 rpm) and a 32 GB mSATA SSD from Samsung...

"Toshiba use a 640 GB hard drive from Hitachi (Travelstar series, 5.400 rpm) and a 32 GB mSATA SSD from Samsung (PM830 series) for such a hybrid solution. It is difficult to measure the resulting performance with conventional tools: depending on the media currently accessed, transfer rates and the access times vary from very fast to slow. However, the OS, browser and other important applications definitely profit from the dedicated cache."
