The same is true for HDDs or for any other data storage devices.

I have stored data for more than 5 years on HDDs, but fortunately I have been careful to make a duplicate for all HDDs and I did not trust the error-correction codes used by the HDDs, so all files were stored with hashes of the content, for error detection.

On the HDDs on which data had been stored for many years, only seldom I did not see any error. Nevertheless, I have not lost any data, because the few errors never happened in the same place on both HDDs. The errors have been sometimes reported by the HDDs, but other times no errors were reported and nonetheless the files were corrupted, as detected by the content hashes and by the comparison with the corresponding good file that was on the other HDD.
