External USB Drive keeps disconnecting periodically

Hi

We have an external 2TB Seagate drive connected directly to a VM (Windows10) running on Hyper V. THe Disk is listed as OFFLINE in the host and the VM detects the drive fine. In the event viewer I can see a bad block error on DR1. These are the only errors relating to disk. I know seagate drives have loads of issues however in a VM where do I start looking. I want to run a chkdsk after backing up the drive contents. Any other ideas to look for? Could be the physical drive is failing.

Is it possible that the USB disk has a power saving mode that spins it down after a period of inactivity?

"Could be the physical drive is failing."

Contact Seagate to see if they have a diagnostic to run.

Could also ask Seagate about the power saving option.
