If you own a portable USB drive, don’t budget it as extra recording space for HomeBase 3. eufy’s USB support guidance distinguishes the rear USB ports from the storage expansion bay.
Identify what you have before shopping
Write down the model of your spare drive and whether it is a sealed portable USB unit or a drive that independently meets eufy’s bay requirements. For recording expansion, use eufy’s current compatible-drive guidance for the S380; a USB enclosure is not proof that the drive inside fits or is supported. If the only reason for the purchase is preserving a few clips, check whether exporting them meets your need without increasing recording capacity.
Protect the files before reusing a drive
If you already have a supported drive, move its contents to a separate location first and open a few copied files to verify them. Treat storage initialization as potentially destructive. After installation using the manufacturer’s steps, check that the app recognizes the new storage and can replay a fresh recording before treating the expansion as finished.
