Documentation eludes to "Wipe Memory on Dismount" (http://www.softperfect.com/products/ramdisk/manual/adding_disk.htm) RAMDisk on dismount but I cannot see the option in v3.4.2
(For the record I had numerous Windows Restore issues which were fixed by the Emulate Hard Disk option in Windows 7 and RAM Disk 3.4.2 so many thanks for a great product - much appreicated).
