In short: buy a cheap ups power strip or a generous USB powebank capable to being under charge 24/7 and do not let the HDD switch off on power loss…
That is a guaranteed recepy to destroy your data and possibly the hardware as well as spinning disks don’t like abrupt shutoff and that applies to data being written on SSDs as well.
Remounting after the power resumes is the last of the issues, easily fixed by a amount/mount command with the proper fstab setup.





I was thinking of 2.5" inch USB drives powered by USB cables…
For 220v ones get a proper ups power strip. They are cheap about 50-60 bucks
