I Keep getting 'Low Disk Volume' messages in Windows XP. The disk seemingly refuses to automatically expand even though this option is turned on. I shut down the the virtual machine and try to expand manually but I get this message: 'Failed to resize the virtual hard disk. An internal error occured while resizing the disk.' Clicking on 'More Details' in the dialogue I get 'Resizing failed. Unable to resize the last volume. The file system of this volume might be damaged or not supported.' I have tried cloning the volume and resizing the clone but the same error occurs. Following the suggestion from another thread C: => Options => Tools => Check Disk did not have the desired effect either. This is a new problem. The disk has happily expanded in the past and I have no problem compressing the disk or its clones. Suggestions will be much appreciated. Mac OSX Snow Leopard with Parallels 6.0.12094
