You seem to have a pretty good understanding of the basic mechanics - chains, files, etc. All you need to do is visualize those components in the modern setting of a USB drive.

It's not just water that can cause loss of chains - largely through rust damage. Many chains are lost due to abrasion caused by having too many files on one drive, too close together. Sometimes parts of a single file can be scattered throughout the drive, potentially causing even more damage.

That's why, if you pay a little extra, you can get a belt-driven USB drive and then you don't have to worry about the chains at all.
