ImDisk: Create physical memory drive (not virtual memory drive) from command-line

Add parameter: -o awe

I wanted this on a server where permissions are a bit more complex, so here's the full command line for getting a physical RAM disk setup with ImDisk, creating a directory (so you can assign more complex permissions - there are limitations on full drive access), and assigning modify permissions to a group by its name.

imdisk -a -o awe -s 512M -m R: -p "/fs:ntfs /q /y"
cd R:
R:
mkdir r
icacls "R:\r" /grant Web:(OI)(CI)M

So it's saying to:

• -a: Make a virtual disk
• -o awe: In physical RAM
• -s 512M: 512 MB in size
• -m R:: Named R
• -p...: Tells it to format the disk with default parameters, quietly.

It switches to R, makes the dir r, and then icacls grants permissions to the group "Web" (if you wanted a user, just use their name here instead, no syntax difference), (OI)(CI) every file and folder inside should inherit this permission M Modify, which is read, list, write, create/delete/modify.
