SMART Attributes
ID
Spin Up Time
03h
Reports a fixed value of zero (0).
Start/Stop Count
04h
Reports a fixed value of zero (0).
Re-allocated Sector Count
The raw value of this attribute shows the
05h
number of retired blocks since leaving the
factory (grown defect count).
Power-On Hours Count
Reports the cumulative number of power-on
hours over the life of the device. However,
the On/Off status of the Device Initiated
Power Management (DIPM) feature will
affect the number of hours reported. If DIPM
09h
is turned On, the recorded value for
power-on hours does not include the time
that the device is in a "slumber" state. If
DIPM is turned Off, the recorded value for
power-on hours should match the clock
time, as all three device states are counted:
active, idle and slumber.
Power Cycle Count
The raw value of this attribute reports the
0Ch
cumulative number of power cycle events
over the life of the device.
AAh
Available Reserved Space
Program Fail Count
The raw value of this attribute shows total
ABh
count of program fails and the normalized
value, beginning at 100, shows the percent
remaining of allowable program fails.
Erase Fail Count
The raw value of this attribute shows total
ACh
count of erase fails and the normalized
value, beginning at 100, shows the percent
remaining of allowable erase fails.
SATA Downshift Count
The count of the number of times SATA
1
B7h
interface selected lower signaling rate due
to error.
End-to-End Error Detection Count
Reports number of errors encountered
B8h
during logical block address (LBA) tag
checks, within the SSD data path.
Uncorrectable Error Count
The raw value shows the count of errors
BBh
that could not be recovered using Error
Correction Code (ECC).
Power-Off Retract Count (Unsafe Shutdown
Count)
The raw value of this attribute reports the
cumulative number of unsafe (unclean)
C0h
shutdown events over the life of the device.
An unsafe shutdown occurs whenever the
device is powered off without STANDBY
IMMEDIATE being the last command.
