This time round I have used a free bootable CD called CopyWipe (great utility, BootIt NG is also worth a mention). Each drive was given 5 passes, and then taken to with a hammer just to be sure. I've linked a picture to the "after" shot.
I can see data destruction being a larger problem as time goes on. I'd be interested to know the techniques others use for this problem.

The next solution was commissioning a Linksys NSLU2 running uNSLUng and ftpd-topfield to allow FTP access to the unit (my computer isn't anywhere near the TV and the Topfield only has a USB port). So the space problem on the Topfield was fixed, but I had loads of transport stream files sitting on my computer. It was just too expensive (time-wise) to edit out all the ads, convert to MPEG-2 and burn to DVD or DivX. So last weekend I scripted it:
- Create ad removal cutpoints with comskip
- Feed the cutpoints into ProjectX then demux
- Combine the audio and video into an MPEG-2 file with mplex
- Encode with Dr. DivX OSS
The whole thing was fairly trivial after reading the CLI documentation for each program, but if you need a hand feel free to contact me.

- Shuts down the server in the event of an extended power outage thanks to APC PowerChute.
- Backs up the VMDK files to locally attached USB hard drives.
- Allows remote administration via Terminal Services (Remote Desktop).
- Hosts my complex virtual networking services including NAT (with port forwards) and routing for the virtual machines.
If anyone out there has made the move, I'd love to hear their experiences and feedback!

Windows Registry Editor Version 5.00Save the above contents to a file with the extention ".REG" and double-click it to install the entries. You may have to fix the lines if they wrap. You will now find that next time you open the program the registration prompt will be gone.

OK, so I signed up and purchased the Linksys device. I set the networking stuff through the phone then followed the guide on the PennyTel website to configure SIP (VoIP connectivity stuff). I was feeling pretty good about the whole thing, that is until I made the first phone call!
I thought I'd try to impress a mate so I called up one of my tech savvy friends and told them I was using VoIP to talk to them. The quality sounded quite good, then after 32 seconds the call dropped out! I had called a mobile so I thought it may just be a glitch. The next two calls resulted in the same drop out after 32 seconds. By this stage my friend thought it was quite amusing that my new phone service was so unreliable after I had been boasting about the cheap call rates!
After hours of Googling and messages back and forth between PennyTel support, I still hadn't managed to avoid the call drop out, or another intermittent problem where the SIP registration was randomly failing. The settings looked fine, and PennyTel didn't appear to have any outages as I tested things with a soft phone from another DSL connection. I was really regretting the whole thing, and getting pretty pissed off. I had a think about the whole scenario, and the only thing I hadn't eliminated was my DrayTek Vigor 2600We ADSL router. I had already set the port forwards required for the Linksys SPA (UDP 5060-5061 and 16384-16482) so thought nothing more of router configuration. As a last resort, I searched the Internet for people running VoIP through their DrayTek to see if any incompatibilities existed. I came across a site with someone experiencing my exact problem, and they had a workaround! It appears that the 2600We has a SIP application layer proxy enabled by default. This really confuses things on the Linksys and has to be disabled. After telnetting to the device and entering the following command, things were working great:
sys sip_alg 0
Note that you may need to upgrade your DrayTek firmware for this command to be available.
After the changes I made some calls and no longer got disconnected after 32 seconds! Woohoo! At the end of the day I'm glad I chose VoIP for the cost savings, even though it caused me grief the first few days.Update: One other setting I have found needed a bit of tweaking was the dial plan. Here is my current Brisbane dial plan for an example:
