1. Check the USB port
If your StoreJet is connected through a USB 2.0 port, it must be unplugged and reconnected after you safely eject it. This is required for the drive to be recognized again.
For the best performance, please connect your StoreJet to a USB 3.0/3.1/3.2 port instead.
Note: A USB 3.0/3.1/3.2 port is recommended to ensure sufficient power for your StoreJet.
2. Check system compatibility
Only the systems listed below support reconnecting the drive using the One-Touch Backup button:
Windows: Windows 10 or later
macOS: Mac computers with Intel or M1 chips
3. Check your firmware version
If you meet all the requirements above but your StoreJet still cannot reconnect using the One-Touch Backup button, please update the drive’s firmware to the latest version:
