After compacting the VHD for one of my virtual machines, I saw this error while trying to restart the machine:

An error occurred while attempting to start the selected virtual machine(s).

Account does not have permission to open attachment ‘D:\Directory\Data.vhd’. Error: ‘General access denied error’(0×80070005). (Virtual machine ID F4076715-AF1E-414C-BEB9-28D67B97E20F)

Of course I was taken aback, because I hadn’t changed any permissions on the file, I just compacted it. Though in the act of compacting the system probably created a new file, then deleted the old one and renamed the new one. So I went searching on Google for some kind of answer.

This page was the one that set me on the right course. The simple answer was to give Full Control to the Users group on the file. After that the virtual machine started with no problems. My other VHDs don’t have Full Control for the Users group, they only have Read and Execute. But they do have Read and Write permissions set for a special user, F4076715-AF1E-414C-BEB9-28D67B97E20F. Notice this is the same user that was mentioned in the error message. I couldn’t find an easy way to add that user to the VHD in question, though, so I gave all users Full Control instead, and I’m trusting that there shouldn’t be any consequences to that down the road.

It’s far too seldom that fog rolls into Carson City. I wish it would happen more often, but it usually seems like it’s only in January that we get any kind of serious fog to speak of. This weekend we’ve been treated to some great soupy fog both Saturday and Sunday mornings, stuff that just rolls in and wraps itself around all the buildings in town. Of course it’s been burning off later in the day, and it looks like the weather systems are going to change next week to bring in more of a real storm. But it has given us two fantastic mornings so far. The only thing missing is the pogonip that comes when you combine fog like this with low temperature; the temps in the morning have been hovering in the 30s, a little too warm for true pogonip to form. 2005 brought us some excellent pogonip; go back and look at those pictures.

But back to the present; here are a few looks around town from the fog this weekend.

Sam said “I Want an Electricital Train!” Jack said exactly nothing. But at least he didn’t freak out, because he saw Sam go first.

Most of the time it really does seem like my boys are doing everything at once.

Take your lens off the camera. Turn it around. Hold it up to the body backwards, with the mount facing outwards. You can do fantastically close macro photography with it that way. But you have to watch out because the depth of field is terribly narrow, the slightest tremor in your hands can blur the image, and you lose all control of aperture and focus. But you can get really close.

Reverse lens, the poor man’s macro lens
