Hello Experts,

I have installed Windows Virtual PC under Windows 7 Professional 64 Bits.

It works fine when I run the VM from a local hard disk (c:), nevertheless when I move the VM files into a USB external HDD I cannot run the VM and I get the following error:

‘PCNAME’ could not be started because virtual hard disk-related error occurred. This could be due to insuficient free space in the virtual hard disk file, lack of write access to the directory that contains the virtual machine configuration file or missing parent disk for a differencing virtual hard disk.

When I open the settings for the VM, under Hard Disk 1 I have the error:

The file 'PATHANDFILENAME.vhd' is not a valid virtual hard disk.

If I move the files back to the C drive everything works fine.

The USB drive is a 500Mb NFTS formatted with everyone full control.

What do I need to do to solve this issue?

Thanks in advance,
