About this blog…

I am employed by Netnod as head of engineering, research and development and am among other things chair of the Security and Stability Advisory Committee at ICANN. You can find CV and photos of me at this page.

As I wear so many hats, I find it being necessary to somewhere express my personal view on things. This is the location where that happens. Postings on this blog, or at Facebook, Twitter etc, falls under this policy.

The views expressed on this post are mine and do not necessarily reflect the views of Netnod or any other of the organisations I have connections to.

USB and FireWire

So I have this external USB/FW drive that I use for TimeMachine on my mac. I have (unfortunately) some other data on that as well. Day before yesterday it just stopped working, making the Finder unresponsible. I had to leave my hotel room in Hyderabad, so I yanked the cable.

Bad thing, but what should I have done? I think the damage was done already.

End result is that the drive is not visible. I see with USB Probe (part of Developer package) something on the USB bus that is suspended. Also, the drive does not turn off and stop spinning when the computer is turned to sleep. Indication that it might hopefully be a state problem in some machinery somewhere.

Anyway, I then thought I could try FireWire access instead, if it is the USB driver on the disk that is confused. So I borrowed a FireWire cable of my friend Kurtis. Cool, if it was the case I had something to connect the cable to in the other end.

Lesson learned: If you want to connect something via a cool interface, ensure you have not only the cable, but also something to connect the cable to in the other end.
