How to check SMART Failure Predict Status of drives on Windows 11/10
S.M.A.R.T (Self-Monitoring, Analysis and Reporting Technology) often written as SMART is a monitoring system included in computer hard disk drives (HDDs), solid-state drives (SSDs), and eMMC drives.
Its primary function is to detect and report various indicators of drive reliability with the intent of anticipating imminent hardware failures. In this post, we will show you how to check SMART Failure Predict Status of drives in Command Prompt, PowerShell, and Performance Monitor.
Check SMART Failure Predict Status of Drives in Windows 11/10
You must be signed in as an administrator to use this option.
If a hard drive (HDD) is currently in a turned-off state after being idle, it will not show up in this report. Only drives currently turned on and running will show up in this report.
1] To check SMART Failure Predict Status of Drives in Command Prompt, do the following:
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type cmd and then hit Enter to open Command Prompt.
- In the command prompt window, type the command below and press Enter.
wmic /namespace:\\root\wmi path MSStorageDriver_FailurePredictStatus
- If the PredictFailure of a drive shows as FALSE, then no issues were found with the drive.
- If the PredictFailure of a drive shows as TRUE, then look up the Reason number for the ID in the table at the end of this post for what it means.
2] To check SMART Failure Predict Status of Drives in PowerShell, do the following:
- Press Windows key + X to open Power User Menu.
- Then press i on the keyboard to launch PowerShell.
- In the PowerShell console, type in or copy and paste the command below and hit Enter.
Get-WmiObject -namespace root\wmi -class MSStorageDriver_FailurePredictStatus
- If the PredictFailure of a drive shows as FALSE, then no issues were found with the drive.
- If the PredictFailure of a drive shows as TRUE, then look up the Reason number for the ID in the table at the end of this post for what it means.
Related: SMART Failure Predicted on Hard Disk error.
3] To check SMART Failure Predict Status of Drives in Performance Monitor, do the following:
- Invoke the Run dialog box.
- In the dialog box, type
perfmon
and hit Enter to open Performance Monitor. - Expand Data Collector Sets, expand System in the left pane of Performance Monitor.
- Right-click or press and hold on System Diagnostics, and click/tap on Start.
This report will now start collecting data for 60 seconds. It may take up to an additional 60 seconds for the report to be generated.
- When the System Diagnostics report has finished generating, expand Reports > System > System Diagnostics in the left pane of Performance Monitor.
- Under System Diagnostics, click/tap on a report that was created (collected) on this date and time, and expand Disk Checks in the Basic System Checks section under Warnings.
If SMART Predict Failure Check shows FALSE with a value of 0 and Description shows as Passed, then no issues were found with the drive.
If SMART Predict Failure Check shows FALSE with a value other than 0, then look up the number for the ID in the table below for what it means.
Known ATA S.M.A.R.T. attributes (ID codes):
Drives do not support all attribute codes (ID). Some codes are specific to particular drive types (magnetic platter, flash, SSD). Drives may use different codes for the same parameter.
If a drive is reported to have a critical status, it is recommended to back up and replace the drive immediately.
IDAttribute nameDescription
0No issues found.
01
0x01
Read Error Rate
(Vendor specific raw value.) Stores data related to the rate of hardware read errors that occurred when reading data from a disk surface. The raw value has different structure for different vendors and is often not meaningful as a decimal number.
02
0x02
Throughput Performance
Overall (general) throughput performance of a hard disk drive. If the value of this attribute is decreasing there is a high probability that there is a problem with the disk.
03
0x03
Spin-Up Time
Average time of spindle spin up (from zero RPM to fully operational [milliseconds]).
04
0x04
Start/Stop Count
A tally of spindle start/stop cycles. The spindle turns on, and hence the count is increased, both when the hard disk is turned on after having before been turned entirely off (disconnected from power source) and when the hard disk returns from having previously been put to sleep mode.
05
0x05
Reallocated Sectors Count
Count of reallocated sectors. The raw value represents a count of the
bad sectors
that have been found and remapped. Thus, the higher the attribute value, the more sectors the drive has had to reallocate. This value is primarily used as a metric of the life expectancy of the drive; a drive which has had any reallocations at all is significantly more likely to fail in the immediate months.
06
0x06
Read Channel Margin
Margin of a channel while reading data. The function of this attribute is not specified.
07
0x07
Seek Error Rate
(Vendor specific raw value.) Rate of seek errors of the magnetic heads. If there is a partial failure in the mechanical positioning system, then seek errors will arise. Such a failure may be due to numerous factors, such as damage to a servo, or thermal widening of the hard disk. The raw value has different structure for different vendors and is often not meaningful as a decimal number.
08
0x08
Seek Time Performance
Average performance of seek operations of the magnetic heads. If this attribute is decreasing, it is a sign of problems in the mechanical subsystem.
09
0x09
Power-On Hours
Count of hours in power-on state. The raw value of this attribute shows total count of hours (or minutes, or seconds, depending on manufacturer) in power-on state. “By default, the total expected lifetime of a hard disk in perfect condition is defined as 5 years (running every day and night on all days). This is equal to 1825 days in 24/7 mode or 43800 hours.”
On some pre-2005 drives, this raw value may advance erratically and/or “wrap around” (reset to zero periodically).
10
0x0A
Spin Retry Count
Count of retry of spin start attempts. This attribute stores a total count of the spin start attempts to reach the fully operational speed (under the condition that the first attempt was unsuccessful). An increase of this attribute value is a sign of problems in the hard disk mechanical subsystem.
11
0x0B
Recalibration Retries
or
Calibration Retry Count
This attribute indicates the count that recalibration was requested (under the condition that the first attempt was unsuccessful). An increase of this attribute value is a sign of problems in the hard disk mechanical subsystem.
12
0x0C
Power Cycle Count
This attribute indicates the count of full hard disk power on/off cycles.
13
0x0D
Soft Read Error Rate
Uncorrected read errors reported to the operating system.
22
0x16
Current Helium Level
Specific to He8 drives from HGST. This value measures the helium inside of the drive specific to this manufacturer. It is a pre-fail attribute that trips once the drive detects that the internal environment is out of specification.
170
0xAA
Available Reserved Space
See attribute E8.
171
0xAB
SSD Program Fail Count
(Kingston) The total number of flash program operation failures since the drive was deployed. Identical to attribute 181.
172
0xAC
SSD Erase Fail Count
(Kingston) Counts the number of flash erase failures. This attribute returns the total number of Flash erase operation failures since the drive was deployed. This attribute is identical to attribute 182.
173
0xAD
SSD Wear Leveling Count
Counts the maximum worst erase count on any block.
174
0xAE
Unexpected Power Loss Count
Also known as “Power-off Retract Count” per conventional HDD terminology. Raw value reports the number of unclean shutdowns, cumulative over the life of an SSD, where an “unclean shutdown” is the removal of power without STANDBY IMMEDIATE as the last command (regardless of PLI activity using capacitor power). Normalized value is always 100.
175
0xAF
Power Loss Protection Failure
- Bytes 0-1: Last test result as microseconds to discharge cap, saturates at max value. Test result expected in range 25 <= result <= 5000000, lower indicates specific error code.
- Bytes 2-3: Minutes since last test, saturates at max value.
- Bytes 4-5: Lifetime number of tests, not incremented on power cycle, saturates at max value.
Normalized value is set to one on test failure or 11 if the capacitor has been tested in an excessive temperature condition, otherwise 100.
176
0xB0
Erase Fail Count
S.M.A.R.T. parameter indicates a number of flash erase command failures.
177
0xB1
Wear Range Delta
Delta between most-worn and least-worn Flash blocks. It describes how good/bad the wearleveling of the SSD works on a more technical way.
179
0xB3
Used Reserved Block Count Total
“Pre-Fail” attribute used at least in Samsung devices.
180
0xB4
Unused Reserved Block Count Total
“Pre-Fail” attribute used at least in HP devices.
181
0xB5
Program Fail Count Total
or
Non-4K Aligned Access Count
Total number of Flash program operation failures since the drive was deployed.
Number of user data accesses (both reads and writes) where LBAs are not 4 KiB aligned (LBA % 8 != 0) or where size is not modulus 4 KiB (block count != 8), assuming logical block size (LBS) = 512 B.
182
0xB6
Erase Fail Count
“Pre-Fail” Attribute used at least in Samsung devices.
183
0xB7
SATA Downshift Error Count
or
Runtime Bad Block
Western Digital, Samsung or Seagate attribute: Either the number of downshifts of link speed (e.g. from 6Gbit/s to 3Gbit/s) or the total number of data blocks with detected, uncorrectable errors encountered during normal operation. Although degradation of this parameter can be an indicator of drive aging and/or potential electromechanical problems, it does not directly indicate imminent drive failure.
184
0xB8
End-to-End error / IOEDC
This attribute is a part of Hewlett-Packard’s SMART IV technology, as well as part of other vendors’ IO Error Detection and Correction schemas, and it contains a count of parity errors which occur in the data path to the media via the drive’s cache RAM.
185
0xB9
Head Stability
Western Digital attribute.
186
0xBA
Induced Op-Vibration Detection
Western Digital attribute.
187
0xBB
Reported Uncorrectable Errors
The count of errors that could not be recovered using hardware ECC (see attribute 195).
188
0xBC
Command Timeout
The count of aborted operations due to HDD timeout. Normally this attribute value should be equal to zero.
189
0xBD
High Fly Writes
HDD manufacturers implement a
flying height
sensor that attempts to provide additional protections for write operations by detecting when a recording head is flying outside its normal operating range. If an unsafe fly height condition is encountered, the write process is stopped, and the information is rewritten or reallocated to a safe region of the hard drive. This attribute indicates the count of these errors detected over the lifetime of the drive.This feature is implemented in most modern Seagate drives and some of Western Digital’s drives, beginning with the WD Enterprise WDE18300 and WDE9180 Ultra2 SCSI hard drives, and will be included on all future WD Enterprise products.
190
0xBE
Temperature Difference
or
Airflow Temperature
Value is equal to (100-temp. °C), allowing manufacturer to set a minimum threshold which corresponds to a maximum temperature. This also follows the convention of 100 being a best-case value and lower values being undesirable. However, some older drives may instead report raw Temperature (identical to 0xC2) or Temperature minus 50 here.
191
0xBF
G-sense Error Rate
The count of errors resulting from externally induced shock and vibration.
192
0xC0
Power-off Retract Count
,
Emergency Retract Cycle Count
(Fujitsu), or
Unsafe Shutdown Count
Number of power-off or emergency retract cycles.
193
0xC1
Load Cycle Count
or
Load/Unload Cycle Count
(Fujitsu)Count of load/unload cycles into head landing zone position. Some drives use 225 (0xE1) for Load Cycle Count instead.Western Digital rates their VelociRaptor drives for 600,000 load/unload cycles, and WD Green drives for 300,000 cycles; the latter ones are designed to unload heads often to conserve power. On the other hand, the WD3000GLFS (a desktop drive) is specified for only 50,000 load/unload cycles.
Some laptop drives and “green power” desktop drives are programmed to unload the heads whenever there has not been any activity for a short period, to save power. Operating systems often access the file system a few times a minute in the background, causing 100 or more load cycles per hour if the heads unload: the load cycle rating may be exceeded in less than a year. There are programs for most operating systems that disable the
Advanced Power Management
(APM) and
Automatic acoustic management
(AAM) features causing frequent load cycles.
194
0xC2
Temperature
or
Temperature Celsius
Indicates the device temperature, if the appropriate sensor is fitted. Lowest byte of the raw value contains the exact temperature value (Celsius degrees).
195
0xC3
Hardware ECC Recovered
(Vendor-specific raw value.) The raw value has different structure for different vendors and is often not meaningful as a decimal number.
196
0xC4
Reallocation Event Count
Count of remap operations. The raw value of this attribute shows the total count of attempts to transfer data from reallocated sectors to a spare area. Both successful and unsuccessful attempts are counted.
197
0xC5
Current Pending Sector Count
Count of “unstable” sectors (waiting to be remapped, because of unrecoverable read errors). If an unstable sector is subsequently read successfully, the sector is remapped and this value is decreased. Read errors on a sector will not remap the sector immediately (since the correct value cannot be read and so the value to remap is not known, and also it might become readable later); instead, the drive firmware remembers that the sector needs to be remapped, and will remap it the next time it’s written. However, some drives will not immediately remap such sectors when written; instead the drive will first attempt to write to the problem sector and if the write operation is successful then the sector will be marked good (in this case, the “Reallocation Event Count” (0xC4) will not be increased). This is a serious shortcoming, for if such a drive contains marginal sectors that consistently fail only after some time has passed following a successful write operation, then the drive will never remap these problem sectors.
198
0xC6
(Offline) Uncorrectable Sector Count
The total count of uncorrectable errors when reading/writing a sector. A rise in the value of this attribute indicates defects of the disk surface and/or problems in the mechanical subsystem.
199
0xC7
UltraDMA CRC Error Count
The count of errors in data transfer via the interface cable as determined by ICRC (Interface Cyclic Redundancy Check).
200
0xC8
Multi-Zone Error Rate
The count of errors found when writing a sector. The higher the value, the worse the disk’s mechanical condition is.
200
0xC8
Write Error Rate
(Fujitsu)The total count of errors when writing a sector.
201
0xC9
