I have a Seagate 2 TB disk that worked well with Ubuntu and Windows.
Recently, after some data transfer, an attempt to safely remove the disk was stopped with an error: "an operation is already pending".
I restarted the PC (in hindsight, probably a mistake) and tried connecting the disk again.
Now the disk is getting detected in Disks, but causes Disks to hang.
It also shows up in the File Explorer, but I'm unable to open it from there as well. The disk lights up as it would normally.
It takes slightly longer (about 10 seconds more) to show up in the File Explorer.
The Seagate shows up in Disks, on the left. But then Disks freezes.
