Suddenly getting an error on a virtual machine that was running fine. Looks like the problem may be with the snapshots associated with the VM rather than the vm itself.

"Could not get the storage format of the medium"

Important I get this vm restored. Anyone got ideas or can you lead me to a post which addresses these errors. When I searched, couldn't find anything. Not really sure what the error means.

What version of VirtualBox are you using and what version was the guest created with?
How many snapshots do you have?

Virtualbox 4.1.6 r74713 with 4.1.6 guest additions
5 snapshots
I have tried a couple of hosts: Windows XP, Ubuntu 11.04
Guest that is causing problem is: Windows XP

I think the original guest was created with Virtualbox 4.1.4

I saw this in another post....it looks like a vmdk might be repairable with this tool.

vmware-vdiskmanager -R broken-inconsistency.vmdk

I don't have this tool. Anyone ever tried this tool to successful repair a broken (corrupted) vm?

Have you tried to start the next to last snapshot? This should tell you if the last child is damaged.
Did the guest crash or anything that you remember that would have caused this?

I have tried all snapshots. Each give the same VERR_NOT_SUPPORTED error. That probably means I was wrong about it being a snapshot problem and instead it is probably a base vm problem.

VM was on an external hard drive and I remember seeing errors when it went down. Can't remember the errors. Seems like it was having write issues to the external hard drive.

I have copied the folder for the vm to another drive. Tried to run it there and get:

Failed to open a session for the virtual machine BLOCK 1

No error info.

Result Code: E_FAIL (0x80004005)
Component: ProgressProxy
Interface: IProgress {c20238e4-3221-4d3f-8891-81ce92d9f913}

In the copy I made, even though I am getting the error posted above, it is attempting to load, but it is loading in full screen mode. How do I change states so it is opening in normal window mode. Hitting HOST KEY+F doesn't work because the vm errors before I can get it out of full screen mode. Just want to get out of full screen mode to insure that full screen mode isn't part of the issue.

Post the guests log file (as an attachment) instead. You really want to stay out of the *.vbox file if at all possible.

How much RAM have you assigned to the guest?

299 MB

Have you tried rebooting the host to clear out any cached memory and see if the guest will run then?
