I've got an odd one. I've got four VM's running on a Win2003 x64 server. The VM's files are stored on the "V" drive, in a "VirtualMachines" folder. Three of the VM's work perfectly, but the fourth has repeatedly lost files, necessitating a restore from backup. The really odd part is, it happens while the VM is running, causing the VM to error out and quit running. The vmdk files remain, along with everything else, as far as I can tell, except the folder that's a string of numbers and letters containing an lck file, judging by what I see in the other three VM folders. When I restore that one folder and file from the backup, the VM fires up and runs.
Any idea what could be causing this folder and file to disappear?
