@phillipdewet @danie10 Maybe I'm remembering a dream (lol) but I could've sworn some modern-day filesystems have a verify-on-write option -- i.e. it writes the data, then immediately reads it back (force-bypassing disk cache, so it knows the read went directly to disk), and then compares what it read back with what it tried to write. And only if they match, does the write system call return a success. Yes, there will be a performance hit, but could be useful for lower-quality removable media.
