Seagate Expansion Drive not appearing in file explorer

    I have a 2TB Seagate portable hard drive which worked perfectly fine for a few months and then one day it stopped appearing in file explorer on my Windows 10 PC. It gets detected by my PC because it appears in the "Safely Remove Hardware and Eject Media" icon but doesn't appear in file explorer (not mapped to any drive).

    I've tried accessing it on a friend's PC and another's Mac but to no avail. My other hard drive works just fine using the same cable. I've looked at a few forum sites already and have re-installed drivers, swapped cables etc. but no luck so far.

    One thing to note is that when I eject the device, it says "USB Attached SCSI (UAS) Mass Storage Device" instead of "USB Mass Storage Device". It seems to be appearing in Device Manager in the "Storage Controllers" section instead of the "Universal storage bus controllers" section.

    Would appreciate any help.

    If you have updated driver, swapped cable and tried it on a different PC and it doesn't work, then it died. The USB portion might be working, hence you can eject, but the drive is dead.

    The most common fault with external drives is the USB controller and not the drive. You can try removing the actual HDD from the enclosure, and installing it into the PC, or connecting it externally using an USB adapter or another enclosure.

    *NOTE: If the drive is still under warranty, removing the drive from the enclosure will likely VOID the warranty.
