Hi everyone, first time poster and not that long a time lurker.

I hve just killed my laptop, and am thankful I came across this forum and actually read stuff before I asked about the best choice between the freezer and oven trick lol
Anyhow, I managed to kill my laptop HDD - last it was working, I was transferring files to an external HDD. I had multiple file transfers happening using multiple windows. With hindsight, probably not a smart move, as, well, my laptop was no longer working the next morning. If someone has any ideas about what and how I did this, it would be much appreciated, so I make sure not to repeat it

Ironically, the external HDD has also since died.
Thankfully I had a new laptop, and had already moved 95% of my files, leaving just my everyday files left, and my emails. Cost of recovery is most likely uneconomic, so until I read
HDD Guru and DIY repairs lol... yeah, I was contemplating it!

I will work out what the noise is, get it confirmed and if reasonable, save my pennies for a professional recovery.
That said, I have had had instances where I've had to undertake (really) basic data recovery. The extent of my experience has been using recuva, or removing hard drives and placing them into USB enclosures or adapters. While I'm not planning on becoming a data recovery expert, I would like to find out more. Apologies if these are n00b questions, this is a very new area for me.
My old laptop IDE drive had details on the label for applying jumpers to make it a master or slave drive. is there a beginner's guide to this? Tried it once, crashed my laptop, figured I was doing it wrong. Yes, there is google and youtube, but can you really believe everything you read on the internet? lol
In terms of backups, and looking for data, how do I go about finding where various file types are located? By this I mean say outlook mail, OS product keys etc. Are there any online resources that list the bulk of these, or is it a case of google-fu and list it yourself?
TL;DR - killed laptop, meh. HDD n00b Want to find out more about HDD's and where data is located.
Thanks for reading, appreciated!
