My longest serving mate once asked me to fix his pc. It had been upgraded and upgraded since its inception as cyrix 6x86 machine running windows 95 up to an AMD K6II running Windows XP. His latest change of motherboard wouldn't let it boot so he left it with me, but he asked me not to look at the contents of one drive in particular. We are the kind of mates who endlessly take the p*ss out of each other, and never miss an opportunity to have a dig, so this was a red rag to a bull. I found out that he had a thing for blondes (nothing unusual there). Blondes tied to chairs. Badly Photoshopped celebrity blondes tied to chairs to be precise. As hundreds of images of women with the heads of Brtiney Spears, Melissa Joan Hart or Jenny McCarthy 'shopped onto the bodies of women were beaming back at me from my monitor. I gave him back his computer elaborately tied up with a ball of string with a cheap joke shop blonde wig attached to it, it took him a week to look me in the eye again.
The other one was the father in laws computer, he needed to be upgraded from vista to 7 to be able to run office 2013, the machine was slow so I decided to stick in an SSD, I needed to clear some space as the new drive was 240GB and his drive was 320 and almost full. A quick run of treesize found a 160GB folder named c:\apps\media. I saw one file name in there and didn't need to see any more. That directory was left out of the cloning, the original drive put into a USB caddy and handed back over when the upgrades were done. I told him that his downloaded "songs" were too large but on the original. My mrs later took me aside quietly and said "by songs you mean his porn don't you" as a statement not a question.
