Detecting Storage Issues

In Windows 10 and Windows Server 2016, PowerShell can access storage reliability data so you can find out whether there is something wrong with one of the attached storage drives. This requires Administrator privileges to execute:

 
PS> Get-PhysicalDisk | Get-StorageReliabilityCounter

DeviceId Temperature ReadErrorsUncorrected Wear PowerOnHours
-------- ----------- --------------------- ---- ------------
0                                          0                
1                                          0  
 

To see all available information, use Select-Object:

 
PS> Get-PhysicalDisk | Get-StorageReliabilityCounter | Select-Object -Property *


(...)

The detail and amount of returned data depends on your storage manufacturer and your drivers.
