Counts command, transport, or controller\-level errors reported
by the device. These reflect failed I/O operations not directly
caused by media defects (for example interface, firmware, or
power\-related errors).
This counter is cumulative and never resets to zero, even if
the underlying error condition is resolved.

Counts media\-level errors where data could not be reliably

flash failures and may imply data loss.
