Get-PhysicalDisk | Get-StorageReliabilityCounterWhen to use it
Use as supporting physical-disk evidence when storage health or repeated disconnects are being investigated.
When not to use it
Not every device/provider exposes every counter, and absent data is not proof of health. Do not use the command as a replacement for backup or vendor diagnostics when failure is plausible.
