Did you have a scheduled task or something that recreated the ram disk at startup? If not and if you only use Control Panel applet and you still see your ram disk reappear automatically after next startup, I would guess that you are using Windows 8/8.1. If you shutdown and then start up again (not reboot) i Windows 8/8.1, they by default save state of kernel and drivers, which in this case includes the ram disk to be saved to physical disk. In that case you can see the difference when you select reboot instead of shutdown.
Nope. The machine this occurs on runs Win 7 Pro. I don't have Win 8/8.1 here.
I dual boot Windows and Ubuntu, and originally defined a 512MB ImDisk as Z:. It doesn't matter if I shut down and cold boot into Windows, reboot into Ubuntu and then reboot back into Windows, or reboot Windows because something like an MS Update requires it. When Windows is fully loaded and running, there's a 512MB ImDisk ramdisk seen as Z: This is not a showstopper bug, merely a curiousity.
And there is no schedulked process to create the ramdisk. There is a startup script through Group Policy Editor that populates the ramndisk with data. I use the ramdisk to hold my Firefox profile and cache. The profile is stored on the HD as a zip file, and unzipped to the ramdisk on boot. A corresponding shutdown script zips it back again to catch changes. Firefox is run via a shortcut that specifies the profile to use, and the profile is defined as living on the ramdisk. Firefox has also been told to place the cache on the ramdisk, but it places it in a seperate FFcache directory instead of in the profile, and I don't bother to preserve it between boots.
> Speaking of which, it's nice I can add capacity to an existing ImDisk ramdisk. Is there any chance a future version will let me shrink it as well?
Yes, I have had some plans for that. It should not be too difficult to implement, it seems.
Thank you! If it can be expanded, it should be possible to shrink it. The main issue I can see is not letting it shrink smaller that the space currently occupied by data.
> (I'd love a dynamic ramdisk that could expand and shrink automatically as data was added/removed, but I don't expect to see that.)
That's not as easy as manual expanding/shrinking, but there are ways to solve this.
I didn't think it wouild be easy, which is why I didn't expect to see it.
I would recommend you to try ImDisk Toolkit. There is a feature there called "RamDyn" that creates a ram disk with a fixed virtual size, but where the actual allocated size grows and shrinks automatically when files are created or removed.
Off to look as we speak. The big win for me would be automated growth, so I don't have out of space "Oops!" moments.
Thanks again.
