Virtual PC 2007 Dynamically expanding Hard Disk

    I just got done copying a VPC 2007 Hard disk file to a new computer that is
    running a Host OS as Vista 64bit. The VPC 2007 installed on it is for the
    64bit version.

    But when I open the VCP machine on this new computer it's reporting that
    it's out of disk space. It's only got around 16Gigs for the Hard drive and
    it's set to be "Dynamically expanding virtual hard disk".

    I've gone through the Compact it step in the Virtual Disk Wizard but still
    didn't help.

    I cannot find any where that tells me if there was an initial Maximum size
    set for the Hard Drive.

    I've tried copying files to the hard drive within the VPC to see if that
    would expand the hard drive but it just runs out of space during the copying.

    Can anyone tell me how to expand it or why it's not expanding on it's own?

  2. The maximum size usually defaults to 16GB, unless you pick Vista as
    the OS,then you should get 65GB.

    The system will expand to the limit set when it was created, in this
    case, 16GB.

    You'll need to either image the VM to a larger VHD, or you can try the
    VHD resizer tool.

    Thanks, I wanted to make sure I wasn't doing something wrong. I'll have to
    see if I can get the resizer tool then or go with the image route then.

  4. Make a backup before you use it. I haven't used it personally.
    There should be some older threads here on may not work on a
    boot drive.
    Just google "vhd resizer" and it should take you right to the DL link

    Thanks Steve, I'll do that.

    The resizer by itself makes a *new copy* of the old VHD disk leaving
    it totally unharmed. It makes a new bigger disk, then copies all of
    the data over. The end result is a disk with the old data in a
    partition the same size as before and then an empty unpartitioned
    space on top of that. You need to expand the existing partition into
    the empty space to utilize it. Newer Windows versions can do that but
    for older ones you need 3rd party tools...
