<human>: Give me a shortened version of the text

This happened yesterday, and it might get a little technical but I'll try to keep it simple.

I'm a new business in IT repairs, but I've been working in the industry enough to stand on my own (I think) I've seen bad situations handled with finesse where the blame on a company is so quickly shifted to bad luck, due to the lack of technical expertise from customers. Anyway, a customer drops off her external 3TB HDD to get fixed, the USB port is busted. Soldering may be a little tricky and time consuming so I decided to get a new case for the thing, they cost like $15. After I swap the cases, I plug the HDD into the computer, it was not getting recognized, and was asking to re-format. Re-format all of my customers data, the 10 years of life she has been collecting and transferring to keep safe, the 10 years of life she insisted that could not be lost, and now had entrusted with me. Shit. WTF happened? What went wrong? This has never happened to more before. I turned to every technicians trusty tool, I googled what happened. Turns out in rare instances, some HDD enclosures might cause errors around the 3TB mark. Some kind of mismatch. I decided to take out the HDD and place it directly into a computer so there would be no issues. Again after some googling, this might also cause some corruption issues. Shit, Shit. I'm in the process of doing data recovery (essentially for free, as this would cost her a lot of money and the mistake is my fault), seems like her files are coming in just fine. I hope.
<bot>: I corrupted 3TB of customers data (10 year backup of personal life) for a simple usb port issue. Hoping data recovery works.
