1) mounted hard drives (external devices) randomly dismount and remount when VM is running 2) if you restart the VM, HDs that were previously mounted do NOT re-mount
details: i have a mac mini running 10.9 this mac has several external hard drives connected this mac runs parallels in the guest OS, i run 10.6.8 Server one of the external drives is mounted in the guest OS (via Devices->External Devices) the server serves time machine to my LAN, using the mounted drive from the host OS
periodically, the drive simply dismounts without warning, then shows the "The disk was not ejected properly" error, then the drive re-mounts (auto-dismissing the error dialog) but the drive now has a different mount-point name (has a "1" appended). the new mount point name breaks Time Machine.
this problem occurs daily.
here are some screen shots of the situation:
