The Drive Remembers Itself: Why MediaVault Never Makes You Rescan

Cataloging a drive with 100,000+ photos and videos isn't instant, so the worst possible experience is having to do it again — and again — every time you plug that drive into a different computer, or even the same one after some tool "forgets" what it already knew. MediaVault is built so that never happens: it only ever scans a drive once.

Every drive gets its own memory

The first time MediaVault scans a drive, it writes a hidden catalog directly onto that drive — a permanent ID plus a full record of everything on it. Plug that same drive into any other machine running MediaVault, and it reads that catalog in a couple of seconds and recognizes the drive immediately, instead of walking the file tree from scratch. Even a drive-letter change or a reformat doesn't fool it — a secondary fingerprint means a relabeled drive gets offered a "this looks like your existing archive — relink it?" prompt instead of being treated as brand new.

Only what changed gets touched

Reconnecting a known drive doesn't mean redoing the whole scan either — MediaVault compares what it already knows against what's actually on the drive now and only processes new, changed, or removed files. Add a folder of vacation photos since the last time you plugged it in, and that folder is what gets scanned — not the other 400,000 files that haven't changed.

The result is a tool that treats "I have 15 hard drives from the last decade" as a one-time cataloging job, not a recurring chore every time you go looking for something.
