A very troubling development has taken place in April 1. I personally wasn't there because this was a Saturday evening. But when my boss was trying to print something, she unplugged the backup hard drives while it was backing up. It was setup so that key documents from one computer would be backed up to a folder onto the other computer, and vice versa. This would take place every night. So after a while, the emergency shutdown prompt popped up saying that "A CRITICAL SYSTEM ERROR HAS OCCURRED AND YOUR SYSTEM NEEDS TO GO FOR A SHUTDOWN NOW!" Then when she booted up her computer (fujitsu laptop), it posted fine, but never went through loading the operating system, it showed an error, "HAL.dll is missing." Now after doing some research I found that it was the hardware abstraction layer, and am now completely baffled as to how and what happened. After a recovery it showed that a shutdown command had been run, and absurdly, the hal.dll file was on the desktop. Any ideas as to what might have happened?
