Yes it does!  Showing &quot;no telemetry available&quot; is exactly what it should do.  Crashing = unreliable.  Reporting an error condition = reliable.<p>Immediately?  Took them 5 minutes to reboot the computer.  The scan of the folder would take seconds let alone minutes.  Pinpointing the problem is secondary.  Not killing the patient is primary.<p>&gt; If the program&#x27;s sole purpose is to transform a massive amount of data in real time, it must have disk access by definition. It can&#x27;t not have disk access.<p>And that is the mind set the programmers of the software had.  You have to take care of error conditions.  The processing can&#x27;t have no disk access but no disk access can occur temporarily or permanently.  What can you do?  Pause the processing part of your program.  Or make the processing part treat &quot;no data&quot; as valid input and display something else.<p>Imagine taking that viewpoint with an ECG machine: This machine displays a heart rate waveform.  So it must have a heart rate input.  If there is no heart rate we&#x27;ll just crash requiring a 5 minute reboot.<p>Hell no!  Draw a straight line and set off a buzzer!
