Symptoms and description

This Error is linked to the error messages, alerts, warnings, and symptoms listed below.

Symptom 1: Error message “Disk is down” on the disk management screen.

A disk signature is a four-byte identification put to the first sector of a disk’s MBR (Master Boot Record). The operating system uses it to distinguish between storage devices on a computer. If the signatures of two distinct drives become identical, one is automatically tagged as offline, and its data is no longer accessible. Here’s a screen image of the Windows Disk Management program with an offline replica signature drive:

The disk is offline because it has a signature collision with another disk that is online

The PC will not boot properly if a boot drive gets offline due to a signature collision, and a 0xc000000e error will be displayed on startup. Also, starting with Windows Vista, the system preserves the disk signatures and letters allocated to its drives in the registry at HKLMSYSTEMMountedDevices – make sure to check that registry hive if you wish to change the letters assigned to your drives or restore the previously changed drive signature.
