in [Virtual PC]

From: Michael Taylor on 11 Jul 2008 05:39 I'm running VPC 2007 on Vista x64 Ultimate with SP1. I recently started up a Windows 2000 VM a few times. When I started it again this morning I get the error message... "The startup disk could not be written to. You may not have sufficient privilege to write to the disk. The virtual hard disk has been mounted read-only. Most operating systems cannot boot with a read-only startup disk." The VHD is in My Documents\My Virtual Machines\Windows 2000 Pro That subfolder is 'read-only', like all the other VM subfolders, and when I checked the properties of the VHD itself, it is not marked as read-only, and the security settings allow me full control of it. Does anyone know whay this has happened and how I can fix it? Thanks Mike

From: Michael Taylor on 11 Jul 2008 11:02 Hi Bob, I use Second Copy. I guess its possible the file could have been locked. However, i've restarted my PC several times, with Second Copy not active and still got the problem. I retrieved the VHD from a backup, and that is now working ok. I think the VHD must have become corrupt somehow.

From: Robert Comer on 11 Jul 2008 11:37 You probably should configure Second Copy to exclude backing up the ..VHD's automatically, it could have got corrupt if the VHD was in use and it tried to back it up. I always back up my VHD's separately when I know they're in a safe state. -- Bob Comer <Microsoft MVP Windows - Virtual Machine> On Fri, 11 Jul 2008 16:02:10 +0100, "Michael Taylor" <mike(a)nospam-mtcs.ltd.uk> wrote: >Hi Bob, >I use Second Copy.
