Question Unsafe shut down SMART data

Feb 6, 2019

Dear all,

I have noticed that with fast startup enabled the SMART data on my NVME SSD for unsafe shutdowns increases everytime I shutdown. It does not increase on a restart or with fast startup disabled.

I am running the latest BIOS for my ASUS motherboard, the latest firmware for my intel 760p SSD, and the latest drivers. This is a Windows 10 machine.

I have read that this is to do with the SSD not receiving a shutdown command before the PC powers off.

Is it the OS that is responsible here? Is there a fix? because I like having fast startup enabled.

Many Thanks

Bradley
 
IMHO, I would avoid unsafe shutdowns, even if you need to disable fast startup. SSDs need to do some housekeeping whenever power is removed. That's why many SSDs have backup capacitors. An orderly shutdown would enable cached data to be flushed, and the SSD would know that a power-down was coming, so it could save its critical metadata.
 
Just to update, I have resolved the issue.

The problem is with the Intel NVME driver it seems. Switching to the Microsoft standard NVME driver and turning fast startup back on does not result in unsafe shutdowns being recorded.
