Although my 2Tb USB3 HD connects to my L520 Lenovo laptop fine as USB2 on Windows, and I've successfully saved a small test file on it with Windows, it completely fails on my Ubuntu 20.04.2 LTS 64-bit Gnome 3.36.8. I've also tried it on Ubuntu 21.04 in LIVE DVD mode and it equally fails there.
Since it connects OK on my laptop's same USB ports on Windows, I think that rules out the obvious first suggestion of my Lenovo's USB ports being unable to deliver enough power for USB3.
Meanwhile USB2 HDs automatically mount and connect fine on Ubuntu, which points to an incompatibility between USB3 and Ubuntu

sudo gdisk /dev/sdb yields this doubtful response:

Then gdisk yields:

and parted yields:
sudo parted /dev/sdb Warning: Error fsyncing/closing /dev/sdb1: Remote I/O error Retry/Ignore?
I also tried Ubuntu Disks which shows
2TB block device /dev/sdb. Tried formatting sdb1 with Disks, but get
Error wiping device: Failed to probe the device /dev/sdb1 (udisks-error-quark,0)
I've seen suggestions elsewhere about manually creating a mountpoint for this USB3 drive, but haven't followed them because I can't see why I should have to manually mount USB3 when USB2 drives mount automatically.
Appreciate any thoughts/suggestions
