In fact, apart from simply deleting the files they ought also to use a tool such as WipeInfo (part of the Norton Utilities) to ensure the data is no longer accessible by the use of third-party "undelete" or other data recovery utilities.
I believe a good platform-neutral way to achieve the same effect, after removing the files, is to write a little script that creates a single file that fills the entire volume, and containing repeatedly the character 7, and then again containing repeatedly the character ¬
The bit patterns for these chars are 0101 0101 and then 1010 1010. So, every bit on the disk surface will be cycled at least once, rendering the original data unreadable by any but proper forensic techniques.

Sorry, I missed seeing this question earlier. A dongle was used as a kind of security device against the use of pirated software. It was just a small hardware device connected to a specific port on the machine, and the program it was supplied with would check for its presence before it would run. One of them had a file that he sent to the other, titled "Osama Bin.exe" . About half an hour after the file transfer took place the Security Intellegence service had him lying on the footpath outside his parents house, along with the Armed Offenders Squad. Uh-oh, maybe I should be glad I'm not in NZ then. I just recently downloaded a few humorous MP3 files with titles including "Taliban" and "Bin Laden."

Many people don't realize that deleting a file on most systems doesn't actually erase its contents. The Norton wipe utility is one I've used for years -- Very useful when getting rid of surplus disk drives and you want to be sure nobody will go snooping around for your old data.

Dank U wel / Merci beaucoup.
I am fascinated by a great number of the threads on the other boards here, and I am pleased to have been taught so well by all of you.
I hope is that I can help on the computer and internet board a little, and, like you, I am fond of old valve sets, and I have a general liking of electrical apparatus. I shall try to not be in your way, however!
Tot ziens / Au revoir / Ciao / Later, dude!

Jooles, I only just noticed that you're in Belgium. Bienvenue, je crois que vous êtes le deuxième membre du ECN en Belgique. Great to find so many people with an interest in older equipment. Feel free to look back through the older threads and add to them if you wish.

Ja, ik zag de andere Belg.
Maar niet voor een tidje.
We are still over here; we're still doing it all wrong; driving the wrong side and using round pin plugs with no fuses in our bathrooms and eating all the witloof :-)
One question and this is the wrong forum, but I can't say which the right one is.
In my factory, there is a fuse for the earth connection in each building. In each significant one, there is a transformeur 15000V -> 400/230. It uses a system TN-NET and there is an earth fuse outside each building that has a supply like it. So, why is the fuse there, and I wonder what happens if it goes?
