Intel® Solid-State Drive Toolbox User Guide Start/Stop Count 04 For Intel SSDs, reports a fixed value of zero (0). This type of event is not an issue for SSDs. However, hard disk drives can experience only a finite number of these events, and therefore, must be tracked. Re-allocated Sector Count 05 The raw value shows the number of retired blocks since leaving the factory (grown defect count). Power-On Hours Count The raw value reports the cumulative number of power-on hours over the life of the device. Note: The On/Off status of the Device Initiated Power Management (DIPM) feature affects the number of hours reported. 09 • If DIPM is turned on, the recorded value does not include the time that the device is in a slumber state. • If DIPM is turned off, the recorded value should match the clock time, as all three device states are counted: active, idle, and slumber. Power Cycle Count 0C The raw value reports the cumulative number of power-cycle events (power on/off cycles) over the life of the device. Available Reserved Space AA Reports the number of reserve blocks remaining. The normalized value begins at 100 (64h), which corresponds to 100 percent availability of the reserved space. The threshold value for this attribute is 10 percent availability. Program Fail Count AB The raw value shows total count of program fails. The normalized value, beginning at 100, shows the percent remaining of allowable program fails. Erase Fail Count AC The raw value shows total count of erase fail. The normalized value, beginning at 100, shows the percent remaining of allowable erase fails. SATA Downshift Count B7 The count of the number of times SATA interface selected lower signaling rate due to error. End-to-End Error Detection Count B8 Reports number of errors encountered during Logical Block Address (LBA) tag checks within the SSD data path. The normalized value begins at 100 and decrements by 1 for each LBA tag mismatch detected. The threshold value is 90. Uncorrectable Error Count BB The raw value shows the count of errors that could not be recovered using Error Correction Code (ECC). Temperature - Airflow (Case) Reports the SSD case temperature in degree Celsius. The raw value is as follows: Byte 0 = Current case temperature (°C) BE Byte 2 = Recent minimum case temperature (°C) Byte 3 = Recent maximum case temperature (°C) The normalized value is 100. Case temperature is calculated based on an offset from internal temperature sensor. September 2011 Order Number: 325912-001US Intel® Solid-State Drive Toolbox User Guide 13
