Adding new virtual disk hungs virtualbox when previous location is inaccessible

[gorkem]

When trying to add a new virtual disk (vdi) either from virtual media manager or creating a new virtual drive (windows host),if "defaultHardDiskFolder" was set to an now inaccessible drive letter (e.g. a bootable harddrive with drive letter I:, which is now removed from system) virtualbox hungs.

To reproduce: 1- Open virtual box 2- make default machine an harddisk folder to an USB drive. 3- save and close virtual box 4- remove USB/removable drive 5- open virtual box 6- Try to add a new virtual drive 7- Observe virtual box is hung.

A typematic solution is :

Modify Systemproperties in configuration file

%USER_PROFILE%\.VirtualBox\VirtualBox.xml

e.g. if Systemroperties was:

<SystemProperties defaultMachineFolder="I:\vboxmachines" 
defaultHardDiskFolder="I:\vboxhd" defaultHardDiskFormat="VDI" 
remoteDisplayAuthLibrary="VRDPAuth" webServiceAuthLibrary="VRDPAuth" LogHistoryCount="3"/>

where drive letter I: is inaccessible change to an accessible drive (e.g. C:)

 <SystemProperties defaultMachineFolder="C:\" 
defaultHardDiskFolder="C:\" defaultHardDiskFormat="VDI"
 remoteDisplayAuthLibrary="VRDPAuth" webServiceAuthLibrary="VRDPAuth" LogHistoryCount="3"/>

Please reopen if this is still a problem with a recent VirtualBox release.
