In the shop we have a very good system for repairs. When someone brings their sick computer in, I (usually it's me) write their name, phone number and their description of the problem on a worksheet which Keith designed some time ago. Then when he or his son are ready to repair the computer, they come to me to decode the hieroglyphics I have written ......but that's another story..........!
On the sheet are 2 tick boxes. One says 'Save data,' the other says 'Wipe data'.
If the customer doesn't need their data saving, I put a cross in the 'save data' box but Keith and Giles have, it transpires, taken this to mean that the data needs to be saved.
"No," I explained, "It means that you don't have to save it."
"So why don't you tick the 'wipe data' box?" asked Keith.
"Because you don't have to deliberately wipe it, you just don't have to bother with it," I explain.
Seems logical to me, but not to Keith or Giles!
