Searching a drive that isn't attached

Updated 2026-07-31 · 5 min read

This is the feature nobody mentions until the moment they need it, and then it is the only thing that matters.

The problem it solves

You have four external drives. A file is on one of them. Without a tool that remembers, finding it means plugging in each drive in turn and searching, which is ten minutes and the reason the file stayed lost for a year.

Everything kept records for volumes it had indexed even after they were removed, so a search told you the filename *and which volume it lived on*. You then plugged in that one drive.

What macOS gives you by default

Nothing. Spotlight's index for a removable volume lives on that volume, in .Spotlight-V100 at its root. Unmount the drive and the index goes with it. This is a defensible design — the index travels with the data, so the drive is searchable on any Mac — and it means an unplugged drive is completely invisible to search.

Finder shows nothing, Spotlight returns nothing, and there is no built-in record that the drive ever existed.

How a tool can fix it

The index has to live on your internal disk and be keyed by volume, with records kept after unmount. Then a search over a removed drive can return the filename, the path and the volume name, clearly marked as not currently attached.

Two details make the difference between this being useful and being annoying:

It must say the drive is unplugged. A result you cannot open, presented like one you can, is worse than no result. Double-clicking it should explain, not fail silently.

It must expire eventually. A drive you formatted two years ago should not still be producing results. Retention by last-seen date, with the stale entries dropped, keeps the list honest.

What we do

Everywhere keeps records for volumes it has indexed after they are unmounted, marks those results as belonging to a drive that is not attached, and names the volume so you know which one to plug in. Records are retained by last-seen date rather than forever.

This was one of the specific things Everything got right that no Mac tool we tried had, and it is the feature we get thanked for most.

Doing it without a tool

If you would rather not install anything, make a manifest per drive while it is attached:

cd /Volumes/Archive2023
find . -type f > ~/Documents/manifests/Archive2023.txt

Then search the manifests instead of the drives:

grep -ri "quarterly" ~/Documents/manifests/

Crude, free, and genuinely effective. The output tells you the filename and, from the manifest it matched, which drive to fetch.

Common questions

Why can't Spotlight search an unplugged drive?

Its index lives on the drive itself, in .Spotlight-V100 at the root. Unmount the drive and the index leaves with it.

Can I search an external drive without plugging it in?

Only if something recorded its contents while it was attached. Either a tool that keeps volume records, or a manifest file you made yourself.

How long should unplugged drive records be kept?

Long enough to cover drives you use a few times a year, and no longer. Records for a drive that was reformatted are worse than none.
