My Passport Ultra no longer recognized

I have three Passport Ultra’s - 2 2TB and one 1TB. For some reason they stopped being recognized on my Lenovo Y50-70 laptop computer. They are still functioning properly with an older computer and they used to work fine until this weekend.

I run Windows 10 on this computer and have tried the troubleshoot option in devices and printers (which see the Passport Ultra as a device). It says it is missing the driver and takes me through the driver update and restart sequence, but at the end of that process, the drive is still not there.

When I look at the properties of the drive it says that the driver is missing and list an error code 28.

Hi @fgossieaux, that sounds strange! You’re saying all three drives are not recognised on your Lenovo laptop? I would suggest removing the drives, rebooting the computer, and then plug one of them back in again (using a different USB port). If it still fails to show up, can you check in Disk Management (right-click Start, open Disk Management) and see if the drive is recognised there?

i have this same problem – since i updated windows it says that i am missing the driver – the white light on the drive is flashing but it does not show up in disk management
