What is a file history drive?
File History takes snapshots of your files as you go and stores them on an external hard drive either connected over USB or your home network. Over time, File History builds up a library of past versions of your documents that you can recover if need be.
- You’ll see this message if your File History drive has been disconnected for too long. If you’re backing up to an external drive (like a USB drive), make sure it’s connected to your PC. If you’re backing up to a network location, go to Settings> Update & security > Backup and reselect the network.
- After you’re reconnected, wait for the next scheduled backup or start a backup manually by selecting Settings> Update & security > Backup > More options > Back up now.
The error: File History drive is disconnected
Always keeping your data backed up and updated is a crucial routine. Thanks to File History, you can easily create backups for your files in Windows 8/8.1/10. Sometimes, you may find that your File History drive is disconnected. The specific error message may vary:
✦ “Reconnect your drive. Your File History drive was disconnected for too long. Reconnect it and then tap or click to keep saving copies of your files.”
✦ “Your files will be temporarily copied to your hard drive until you reconnect your File History drive and run a backup.”
When a scheduled backup task is triggered, it will prompt with such an error. By default, File History will save copies of files every hour, so it may be quite annoying if you do not fix it, not to mention that your files are not protected.
