Hi,
After the SSD not used by the VM, first check if the SSD is detached in the VM settings, if not, please detach the SSD in VM.
Then check the disk manager in the Hyper V host. Please try to offline the SSD disk in disk manager, then check if we can eject the drive.
Thanks for your time!
Best Regards,
Anne
