My 500 GB drive doesn’t show up on my MacBook anymore. This started last week. I thought it was the USB C cord. It is not. I have tried 6 cords. I have also tried connecting to my iMac. Nothing. I think the USB connection in the drive is broken. Can I take this drive apart and port the storage to a new container? I have at least a year or two worth of Ableton sessions that i need to get off of this device. I was told this device was next to indestructible and i DID NOT BACK IT UP. First rule of data … not followed ARG! HELP

If your MacBook cannot detect the drive at all, it could be a connection, cable, or hardware issue. The following steps might help you:

  1. Reconnect the Drive – Try different USB ports, avoid hubs.

  2. Check Cable and Port – Swap USB cable or port.

  3. Test on Another Computer – Verify if the drive itself works.
