Recently I added a new drive to my Windows 10 VM using VMFusion 10.0.
I was unable to write to it even after making myself owner of it.
After digging in this for a while it appears that VMWare is treating new SCSI drives as USB devices and blocking writing (even though I can format it).
To fix this:
- Power down your VM
- Bring up the VM Settings
- Under the “Removable Devices” section, click the hard disk you are having issues with
- From the new window, click “Advanced Options”
- Change the BUS type from “SCSI” to “IDE”
