Both are likely true. I.e. Over my 40 years of dealing with computers ,it is likely there were errors which did not become problems.
I have about 20tb of unique files in my personal storage at this point (used to run photography business, plus personal videos and photos,plus movies and tv shows, plus actually important documents which are less than 3% by size).I have about 4-8 computers running around my home doing stuff (plus dozens of computing devices - phones, googles, whatnots).
I understand the overwhelming chance there were many errors over time in running computers or raid transfers or usb backups over decades. They just haven't manifested themselves as problems.
- snvzz 3y agoThe fact that you're dealing with silent corruption does not make it any better, but in fact, much worse. And yes, the corruption is there. DRAM is alarmingly unreliable. Because no ECC, we just do not notice it most of the time, or misattribute the problems it causes.
- qwertox 3y agoIf you're unlucky you get into mode with ZFS where every scrub corrupts more and more data, while ZFS itself thinks that all is OK because it computes the checksum on the data it just corrupted while scrubbing.
