Partition an unallocated hard drive??

I was confused with trying to partition the hard drive since last evening. Here is my computer specifications below:

Acer Aspire M3450M-ER20P Desktop
3.3GHz AMD FX-6100 Processor
8GB DDR3 system memory; Expandable up to 16GB
2TB hard disk drive
16X DVD+/-R/RW optical drive
Windows 7 Home Premium operating system
AMD HD7570 Graphics with 1GB dedicated memory

OK I type " Disk Management " in Search programs and files after click " Start" on taskbar.

No problem to show Disk Management on the screen and right click the hard drive to shrink. To my surprise that I only had 532 MB to shrink the main hard drive with Acer (C: -- 1844.92 GB (Boot, Page File, Crash Dump, Primary Partition -- Healthy) and two other hard drives that have partition as well. One is with System Reserved -- 100 MB (Healthy) and other is 18.00 GB Healthy (Recovery Partition).

I want to create a partition hard drive for RAMDISK with 6 GB but I don't have enough to create a partition hard drive. Because after the shrink report that I only have 532 MB in Acer C: hard drive. Is 532 MB not enough to create to 6 GB hard drive? I think so but could be wrong.

Your help would be appreciated how to make a partition hard drive for RAMDISK.

Thank you,

John

I did this twice last night. So how many times do I have to defrag the hard drive before get a better number of megabytes or gigabytes? I was surprised to see that I don't have enough MB or GB in the hard drive to create a partition hard drive. Which program would be the best to defrag the hard drive? I know Disk Defragmenter takes a while to defrag but any freeware disk defragmenter would be helpful and faster to get the job done.

Anyway here is my Screen Capture Image of Disk Management with file attachment:

Double click the picture and you will see the whole picture then click the arrow <-- on top of the webpage back to normal.

5. This step is the most important. Maximize the Disk Management window so it fills your entire screen. Resize the window components so the status and sizes of the partitions are clearly shown.
