Just an FYI, in case anyone is not aware: my father taught me long ago not to put things on HDDs and then forget about them, expecting the data to remain intact 'forever'. He told me magnetic media change over long periods of time (i.e. years): the bits 'drift' and weaken, and that can lead to unreadable data eventually. He said that, if the drives are in a system, I should run a utility like Scanner in the background that will periodically read the data (and re-write it if needed), to keep the recorded data intact and strong. For drives not in a system he said I should connect them to a system every year or so and run something like SpinRite to refresh the data signals.
He never said anything about SSDs. I'm not sure whether there's any 'magnetic drift' issue with them, although I suspect not.
