I have vmware 9.0 inside my windows 7 , but suddenly my windows 7 shut down due to an error , and it restart again. But when I start my VM I got the following error :-

Failed to lock the file
Cannot open the disk 'C:\Users\XXXX Dev.vmdk' or one of the snapshot disks it depends on.

Can anyone advice what is causing this problem and how I can solve this ? Thanks lot?

  • is the file shown (c:\users\XXX Dev.vmdk) on your disk? is it readable? is it damaged? Can you add information on what you tried?
