I was actually really impressed with this individual! For someone who has less than a year of experience, they're showing quite a bit of initiative, drive, and curiosity - which really are what make or break engineers as they develop. Taking the time to do a blog post (effectively a post-mortem) and share it is even better!
And yes - I've literally done this exact same error (with TB of video data!). Spending the following week remediating all of that data loss was a great lesson in patience and attention to detail. :-)
