DasBoot allows you to use iPod, flash drive, portable HD as bootable diagnostic device.

Do you have a nice new portable music player in your pocket? Or perhaps a flash drive or portable hard drive? Why not turn it into a Mac OS X diagnostic, repair, recovery, and maintenance tool? With SubRosaSoft DasBoot(TM) it's easy. DasBoot allows you to take any third party boot CD (such as those shipped by SubRosaSoft.com Inc, Prosoft Engineering Inc, Alsoft Inc, or Micromat Inc) and quickly create a bootable diagnostic device that contains any of your own utilities that you may wish to install.

You can use your portable more...

Dasboot will create a bootable USB version of the Snow Leopard installer disk, FWIW, but that's all.

I could not - after more than 12 attempts - get this software to create a bootable DiskWarrior or TechTool Pro USB drive.

When I looked at the USB drive contents everything appeared to me as a bootable drive would but it just did not show up as a bootable drive when holding the Option key on my iMac running 10.0.6.

Holding the Option key to restart, the USB drive shows up only as a storage device. When I click to select the device the mouse locks up and the Mac restarts.

There's supposed to be a Subrosasoft launcher that comes up first if this concept worked but it never does. I even ran DiskWarrior v4.0 on the finished USB drive and it found directory errors which I fixed but still did no good.

The USB drive must be formatted correctly, fwiw, to have a GUID partition table which is needed to boot from the device.

I'd like to hear what I've not done correctly! I'd give the software 5 stars if it worked on DiskWarrior or TechTool Pro but since it only makes a bootable Mac OS X drive for now I'll give it a 3-star rating. Dasboot is free, however so that helps.

Moving on from my previous post, I still cannot get this seemingly worthless piece of software to work properly; what a waste of time and effort!
A pity because on paper it seemed to be a good idea ....

The developers comments are conspicuous by their absence from this forum!

Like a lot of other folks here, I cannot get this software to work!
I have a 24" iMac running 10.6.4
I downloaded and installed DasBoot 2.0. I then mounted a Flashdrive and opened DasBoot -it failed to see the Flashdrive! I keep getting the message 'Please insert a valid CD or DVD to use as the source disk' According to the publicity, it should work with a Flashdrive What am I doing wrong? Any ideas would be welcome!

Same here, will not boot from a USB stick, tried every way to boot from it, it will show if I hold down option key, but when selected it just freezes the Mac, and if selected in the Startup Disk it goes around in cycles like NICMART said.

Real shame, would have liked to have had this available as Disk Warrior isn't ready for my new 2010 Mac mini.

In 2007 I tried to install the first version of DasBoot on a USB flash drive and failed. Now I've tried the same with DasBoot 2.0 and failed again. It took a very long time to install DiskWarrier and a few other utilities on an 8GB stick, but the install appeared to be a success. However, when I tried to boot from the stick, holding down the option key and selecting the stick at boot, it didn't take and reverted to booting from the internal drive. So I tried selecting the USB stick from startup disk prefs, and the iMac (Intel) simply rebooted again and again without mounting.

When I had problems in 2007 the developers didn't respond to my request for help. I won't bother to ask this time. They still haven't seen fit to produce any user instructions.

DasBoot costs nothing, and in my experience it is worth nothing.

To actually use this with a USB drive requires an Intel platform. PPC users are limited to using Firewire drives.

A 10.5 compatible version would be very much appreciated. Thanks in advance.

Do we know when they will have a 10.5 compatible version out? Someone posted here in may that it was coming "soon."

Can confirm that version 1.0.2 does not work with OS X 10.5.2. Cannot see source DVD/CD, nor can it see the destination volume. Bummer.

Version 1.0.2 is not working in Mac OS X Leopard. I inserted a DVD of TechTool Pro and it will not even list it. It used to work under Tiger. Is there an update in the works?
