Calling Win32_CDROMDrive freezes the code if the optical drive is burning a disc

Question

Hi

Using MySearcher As New ManagementObjectSearcher(New SelectQuery("Win32_CDROMDrive"))
   For Each MyDisk As ManagementObject In MySearcher.Get()
      ' Just here the code execution hangs if the only optical drive is writing a Blu-ray disc!

The drive is Pioneer BDR-S09XLT original firmware!

Any advise please?

Thanks all :)

Hi @StewartBW ,

The ManagementObjectSearcher.Get() call can hang indefinitely because the WMI query waits for a response from the drive, which might not be able to respond while burning.

You can run the query in a separate thread and enforce a timeout.
