According to Storage Controller info in the device manager it say's the driver version is v12.0.1.1019 of which I have never installed! Can I uninstall it in the device manager & install v13.1.0.1058 there or will this cause issues & is there a process other than using the device manger to update this driver? I don't get it, I was able to get the certificate installed? I thought the modded driver was better than the WHQL?

EXCELLENT, Thank You VERY much for your help! I'll get right on it & resume the install! p.s. Thanks for your dedication & advice!

We have some new dell precision 3620's workstations, which we need them to run Windows 7 32bit
The NVME drives in these workstations are Toshiba - NVME THNSN5256GPUK 256GB
im finding it next to impossible to get them to work tried various other toshiba drivers but no luck, got close installing the recommended microsoft hot fixes via DISM commands to install.wim & boot.wim, you can browse to the drive but can't select it on installation :(

Any thoughts i be greatful?
Just to add i can install Windows 7 64bit to this drive with the Dell ISO image, but not the 32bit version as required

@Fernando,
Samsung NVMe v2.1 , on my system, does not fix the "Unsafe shutdown" problem.
The counter does continue its progression without any specific reason.

Hi Fernando, thankyou for the welcome

Been researching into NVME drivers for quite some time and many links refer to your forum
Windows 7 32bit is needed for an office environment before we roll out to Windows 10
There seems to be very little/no information anywhere on the NVME THNSN5256GPUK 256GB drive, no drivers from the Toshiba support for the XG4 series drive i have
Dell support have only released a 64bit ISO for Windows 7 which enables installation, this is supported in booting of the NVME ssd drive, i need 32bit support which i was hoping was possible
I have contacted OCZ support and they have nothing on this they refer me to Toshiba support who do not have anything for me

I was just hoping another user here may have had success in getting this drive to work with a possible driver/work around.

Hi All -

Has anyone come across a driver provided by OCZ/Toshiba that is for the XG4 series NVMe SSDs? I have an THNSN5512GPUK that I am looking for a driver for. The device works, and I am in Windows, but I suspect that not having a device driver is the reason for 2+ minute boot times on a fresh install of Windows 10. And to clarify by clean, I mean straight off the Microsoft provided ISO of the 15002 build, and updated. All devices in control panel have drivers. This RIDICULOUSLY slow boot time has been present since I removed the stock Dell Windows installation, and went to an insider build.

As a side note - I am on build 15019 and must have atleast 15002 or later for some new features in the Windows Subsystem for Linux that were added that support something I've built at work.

Happy to provide any other information people want, but know that the driver for the XG3 series does NOT work for this device.

Hi Fernando - I did quite a bit of googling before deciding to post here. Here's the device ID for the drive device and the related controller:

Drive - SCSI\DiskNVMe____THNSN5512GPUK_NV4101

NVME Controller - PCI\VEN_1179&DEV_0115&SUBSYS_00011179&REV_01

Hi Fernando - thanks for the information. I suspected as much as I looked for several pages after that person posted asking for drivers. I didn't find anything here, and I have looked at several other forums and pages, some in other languages looking for information. I guess I'm just stuck with the stock Win10 driver for now.
