pass-through-disk

Pass-through disk in Hyper-V allows a virtual machine to directly access a physical disk, such as a USB drive, bypassing the host operating system. This setup is commonly used for scenarios requiring raw disk access, like running a boot loader or managing partitions. Users typically configure it by taking the disk offline on the host, then adding it as a physical hard disk to the VM's SCSI controller. However, issues can arise, such as the VM failing to start with a boot loader error. Troubleshooting involves checking disk connectivity, ensuring the disk is properly offline, and verifying VM settings. This tag covers discussions on pass-through disk configuration, errors, and solutions in Hyper-V environments.
