Run Get-PhysicalDisk | Select FriendlyName, HealthStatus, OperationalStatus to see each drive's health, then pipe to Get-StorageReliabilityCounter for temperature and wear.

01Command

Command
$ Get-PhysicalDisk | Select-Object FriendlyName, MediaType, HealthStatus, OperationalStatus, Size
Get-PhysicalDisk | Get-StorageReliabilityCounter | Select-Object DeviceId, Temperature, Wear, ReadErrorsTotal

02What it does

HealthStatus returns Healthy, Warning, or Unhealthy — Warning usually means SMART has flagged a threshold, which is the early signal to replace the drive before failure. Get-StorageReliabilityCounter is the forgotten follow-up: piped from Get-PhysicalDisk it exposes drive temperature, Wear (SSD wear percentage), power-on hours, and read/write error totals that Disk Management never shows. These counters are what Windows' 'predicted failure' notifications are built on.
