Critical Warning: These bits if set, flag various
warning sources.
Bit 0: Available Spare is below Threshold
Bit 1: Temperature has exceeded Threshold
Bit 2: Reliability is degraded due to excessive media
or internal errors
Bit 3: Media is placed in Read- Only Mode
Bit 4: Volatile Memory Backup System has failed
(e.g., enhanced power loss capacitor test failure)
Bits 5-7: Reserved
Any of the critical warning can be tied to
asynchronous event notification. Drive

“healthy” status when the critical warning
flag is set.

Percentage Used Estimate (Value allowed to exceed
100%)
A value of 100 indicates that the estimated
endurance of the device has been
consumed, but may not indicate a device
failure. The value is allowed to exceed 100.
Percentages greater than 254 shall be
represented as 255. This value shall be
updated once per power-on hour (when the
controller is not in a sleep state).
