New in OSFMount 2.0.1001 (Mar 23, 2018)

  • Updated/added warning and error messages when using format option on command line when specifying a ram drive that is smaller than 260MB.
  • Fixed issue with detecting partitions for ImageUSB images.
  • Microsoft signed OSFMount.sys device driver for Windows 10. This provides compatibility with more versions of Windows.

New in OSFMount 2.0.1000 (Mar 9, 2018)

  • Compiled with Visual Studio 2017 and Driver Built using WinDDK 10. Consequence of this is that the minimum OS required is now Windows 7 SP1 and we are longer supporting older operating systems XP & Vista.
  • Dramatic speed improvements for blank RAM disks. Speed improvements are a result of,
  • New compiler with better code optimization
  • Forcing the RAM drive to be held in physical RAM (if free space is available on initial mounting). So no swapping to disk. Making it more important than ever to make sure you have sufficient free RAM available.
  • Rewrite of the device driver code to remove overheads in the handling of I/O request packets (IRPs), which read and write data from the RAM drive.
  • At the time of this release, we believe this is the fastest RAM drive software available. Some examples of the speed increases compared to the previous release are 290% faster for 4K IOPS reads and 57% faster linear reads.
  • Updated EWF library to libewf-20160424
