This is one error that I’ve seen before in the past, but really rare with SpinRite. One computer at the office was having performance issue. How could a computer with Intel Core i7 be slower than one with Intel Pentium 4, which is the oldest computer in the office. After ruling out malware infestation, I suspected that the hard drive was the source of the problem. I then boot SpinRite on this computer to check the condition of the hard drive. Shortly after running Level 2 (emergency data recovery), SpinRite halted and displayed an error message.
Division Overflow Error!
A critical error occured at: B04E from which SpinRite CANNOT recover. The system has been halted!
I’ve just sent the screenshot to GRC support.
It would be a lot easier for me to get a new hard drive and install a fresh operating system than waiting to get this hard drive repaired.
