Old man AF story time:
For about a decade, I did on-site computer repair. As in: going to people's houses or businesses to fix their computer problems. (Like Geek Squad, but before they were big.)
Lots of random jobs. Of all sorts. My to-go computer at the time was my original, 867 MHz PowerBook G4 with Combo Drive. (Still have it, still works great, original battery still holds more of a charge than a MacBook Pro battery bought in 2009.)
Had a job where a customer's computer was ultra-slow, crashing fairly often. Quick look - hard drive is full. Less than 1 MB free space on Windows 98, on a 4-6 GB hard drive. I tell him he'll need to clean up files. A glance around the hard drive, and he has a folder that's taking up a good 3 GB. Is that safe to delete?
Nope. He must have it. But most of it is archived material, so if I can put it on CD for him, that'll be fine.
Well, his laptop doesn't have a CD burner. Nor does it have Ethernet. (He used dial-up internet.) The only method I have to get data from his laptop to mine to burn the CDs is a USB hard drive.
Yup, USB 1.1 on both machines. I copied ~3GB over USB 1.1 twice, then burned the files over 5 CD-R discs.
He told me the files were confidential work files, I couldn't look in the folder. (The folder was named "work" or similar, and had subfolders of that were just years, I didn't look any further than that.)
But, of course, as the files are copying (SLOOOOOWLY) I can see their files names as the copy dialog box goes. (The customer was in another room at this point, I was just watching the progress bar go by.)
Porn.
Lots of porn.
75% of this hard drive porn.
And since he had dial-up only, it meant he had been downloading it over dial-up. No wonder he didn't want to give it up - it had to have literally taken years to download it all! (Presumably the year-dated folders.)
So he paid me a few hundred dollars to transfer porn from his ancient laptop to CD-R discs. I was rather glad for the slow USB 1.1, as I got paid to watch a progress bar tick by. (No, I didn't save it - that USB drive was solely for "customer data transfer" and I always reformatted it in the customer's presence after use every time.)
