I doubt very seriously that anyone would ever have this need for this but I did and took care of it with ImdiskTK in a flash.
My organization decided to use BitLocker to encrypt ALL fixed disks.via a AD policy and a script. Of course they never advised me of this and when I booted to my laptop it asked me to encrypt my HDDs with a PIN. I dutifully did it and rebooted. Apparently the script also checks for NEW fixed drives at every boot. So it kept asking for encryption on my Imdisk RAM drive as it was recreated at every boot the encryption did not keep.
I could have either created an image to load and keep it encrypted over a reboot or do what I did and simply added the advanced option '-o rem' to the RAM disk. Viola! The RAM disk is now Removable Disk and the policy / script no longer asks for it to be encrypted.
Sometimes it's easy, sometimes it's hard. This one I took care of in just a few minutes.
KUDOS again to the author of Imdisk and the TK.
