I just installed 3.4.6 and mounted a 512 MB disk. No error messages created. Windows Explorer shows the disk with the correct drive name, but will not open with the error message "not accessible". Windows task Manager shows memory taken, but Disk Manager does not show the volume.
Yeah, I have a same problem. It works perfectly like 2 days ago, yesterday fine too. Today I start PC and instal some WIN update and RAM disk not works. Actually it works if I create new disc/image but I need mount old image but it's not working. I tried uninstall that update, reset PC but still same.
So I create new image and working fine - but again today not working again (yesterday before PC off - win update KB2998527 installed) - it's the same update as I uninstall last time. I think that update somehow corrupted image after restart PC in my case.
