That awkward moment you didn't backup and the hdd fails.

Yeah it only happens once

Lots of hard drives failing today: https://www.devrant.io/rants/319229

I'd recommend Spinrite...pricey, but magic, has worked for me many times, well worth it: https://www.grc.com/sr/spinrite.htm

I know someone, who had three backups. At the time, 3,5 discs... The diskdriver of his mac was broken, so it wrote 0x00 on the disc. The person put in all of the three discs in, and had to write his one fear project in one night, as the competition was one day afterwards
