In some case, it might also be an indicator that the disk is about to fail. Or, if you’re experiencing this with an external drive, it’s probably because you removed it without using the Safely Remove Hardware function. In any of the cases presented above, you can use the fsutil command to check the status of the dirty bit. But you’ll need to do it in an elevated command prompt with administrative rights.
