The original Scramdisk is no longer maintained; its author, Shaun Hollingworth, joined Paul Le Roux (the author of E4M) to produce Scramdisk's commercial successor, DriveCrypt. The author of Scramdisk provided a driver for Windows 9x, and the author of E4M provided a driver for Windows NT, enabling cross-platform versions of both programs. Although Scramdisk's source code is still available, it was only released and licenced for private study and not for further development.
There is a new project called ScramDisk 4 Linux which provides access to Scramdisk and TrueCrypt containers. Older versions of TrueCrypt included support for ScramDisk.
