Why does the Enterprise Console show a “No Disk” error?



When I start the Enterprise Console on my computer, I get the error message There is no disk in the drive. Please insert a disk into drive D:.

EC No Disk Error

This “PRTG Enterprise Console.exe - No Disk” error also appears every time I eject a CD or DVD from my local computer. It is almost impossible to close this error message box, no matter if I click “Cancel”, “Try Again”, or “Continue”. Does PRTG and the Enterprise Console cause the “no disk” error or is there another reason? How can I fix this disk drive error when using the EC?

“No Disk” Error with the Enterprise Console

Important notice: The Enterprise Console (EC) is unsupported and deprecated as of PRTG 19.4.53. As of PRTG 19.4.54, the EC installer is removed from PRTG.

We strongly recommend that you switch to the PRTG Desktop, our new alternative interface that you can use to connect to multiple PRTG servers to manage your entire network.

For information on how to uninstall the EC, see How to uninstall the PRTG Enterprise Console from the PRTG Server.

The error message There is no disk in the drive. Please insert a disk into drive D:. is neither a bug in the PRTG Enterprise Console (EC) nor originally caused by the EC. This “no disk” error is a known issue that is generated by the Windows system on which you run your EC and may appear on computers with removable hard disk drives or USB multi-card readers.

Unfortunately, the root cause is not easy to identify, because the error may only happen from time to time and is not reproducible on every system.

Fixing the “No Disk” Error

Although this error is not a big problem in most cases, it can be really annoying. Because it is caused by the Windows computer, we cannot easily provide a fix for the Enterprise Console itself (we will consider this issue for future PRTG desktop clients, though).

However, you can configure your local computer to avoid this error message while you are working with the PRTG Enterprise Console: disable the “no disk” error message by editing the Windows registry.

Steps to Go

Caution: Please backup your system before manipulating the Windows registry!

  1. Open the registry editor and navigate to the following subkey: \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows
  2. Double-click the DWORD ErrorMode to modify its value.
  3. Change the Value of ErrorMode to 2 and click OK to save it.

With this registry hack Windows will not generate the “no disk” error message again.

This error occurs if there is "AutoPlay" for "Software an games" enabled and you insert a CD that autoruns. Go to "Control Panel" --> "AutoPlay" and select in "Software an games" --> "Ask me every time" This applies to Windows 7 OS.

The libraries get hung up. I find a reboot fixes the problem. I'm not a fan of turning off warnings so just rebooting whenever this happens fixes the problem. For me, it only happens if I insert a CD and then eject it - so not very often.

Fully expect this is a PRTG library bug that should be addressed (other application forums on this error indicate such).

Thank you for the post rayb2001, we aim to fix this in the coming months as par of a larger rework of the Enterprise Console. Please bear with us.

A year later and this is STILL not fixed. This is not a windows issue, so don't blame it on Windows. Release a fix, not a work around!!!!!

Hello houch80,

Thank you very much for your reply. As my colleague Torsten already wrote, we are currently working on a bigger update for the Enterprise Console.
Unfortunately, there is no ETA that I can provide you with yet, so please follow with the above mentioned workaround in case you encounter the error message.

Thank you,
