SubRosaSoft has updated DasBoot ( — a free tool that can turn devices such as an iPod, a flash drive or portable hard drive into a Mac OS X diagnostic, repair, and maintenance tool — to version 2.0. The new version is compatible with Mac OS X 10.6 (“Snow Leopard”).

DasBoot allows you to take any third party boot CD (such as those shipped by, Prosoft Engineering, Alsoft or Micromat) and create a bootable diagnostic device that contains any of your own utilities you may wish to install. In addition you can re-configure the device at any time to add new utilities, updated versions of software or newer versions of Mac OS X.

DasBoot has been tested with the following disk utilities and data recovery tools, but will also run many others, according to the folks at SubRosaSoft: CopyCatX, FileSalvage, MacForensicsLab, VolumeWorks, Drive Genius, Data Rescue II, DiskWarrior and TechTool Pro. It’s compatible with Mac OS X 10.5 and higher.
