Any advice is appreciated.
Also in the UK and I suspect that most techies wouldn’t turn you in. They probably have more downloaded material than you do. I’ve had tech support people on the phone telling me what movies they’re currently downloading.
But obviously no-one anywhere can give you a certain assurance that you’re safe, so a practical thing you could do would be to take the laptop’s hard-drive out and see if you can delete the files from another computer before putting it back in and sending it back.
You can connect hard-drives to other computers with an IDE to USB connector, or a SATA to USB connector, depending on what sort of hard-drive is in your laptop. This is the sort of thing I mean. (I hope Advanctec don’t mind me direct linking to the item, only way I can point straight to the connectors). They’re not expensive but maybe someone you know has one?
Wont go into graphic detail on how to do all this, in case you already know all this, but if not, it’s easy enough to learn or ask.
Hope this helps,
