SSD: Number of "Unsafe Shutdowns" increases after each hibernation of Windows 10

[MatthiasB]

Hello,

I noticed the following on my new Laptop with an Intel SSD 660p 1TB SSD: Each time I hibernate Windows the value of the SMART attribute "Unsafe Shutdowns" increases by one. When I shutdown Windows with the "Fast startup" feature enabled (which effectively hibernates the Windows kernel), the value increases by one as well. When I shutdown Windows with the "Fast startup" feature disabled, the value doesn't increase. So the cause for the increase of the "Unsafe Shutdowns" value seems to be the hibernation.

Should I worry about this behaviour, or can it be ignored? Could it be that this is a bug in Windows' hibernation code?

Hello,  @MatthiasB.

Thank you for contacting the Intel Community Support.

I will be working on your ticket regarding the SMART attribute increasing during hibernation, I will be glad to assist you.

Can you provide me with the full system report using Intel SSU and the SMART report using Intel Memory and Storage Tool? You can generate both files and attach them to this ticket:

- Intel MAS: https://downloadcenter.intel.com/download/29820/Intel-Memory-and-Storage-Tool-GUI-?v=t

- Intel SSU: https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-

Since you have determined the reason for this increase and it does not seem particularly worrying, it could be a bug or some error as you mentioned, and it may actually be ignored, but I can try to look for more information just in case.

Hello @BrusC_Intel,

I found a solution to the problem that the "Unsafe Shutdowns" value increases after each hibernation: I installed the driver from "https://downloadcenter.intel.com/download/29172/Client-NVMe-Microsoft-Windows-Drivers-for-Intel-SSDs...". Now the "Unsafe Shutdowns" value doesn't increase any more after hibernation.

The previously installed driver was (according to the device manager): Intel NVMe Controller Version 17.8.0.1065 [09.12.2019]. As the new driver doesn't show the problem anymore, but the old driver does show it, it is probable that it's a bug in the old driver that causes the described problem.

The newly installed driver is listed as "Intel SSD 660p Series" in the device manager.
