I have a five year old Lenovo T420 laptop and last week fitted a Seagate FireCuda 2.5in 1TB SSHD model (i.e. traditional HD with SSD cache), and a Sandisk mSata 32GB SSD cache card (cheap eBay clone? - it had Chinese holograms on it).

My C drive now shows up in Control Panel->Computer Management->Device Manager as WDC WD3200BEKX-60B7WTO.

I'm not complaining about speed - whatever it is it's quick, but why is it being detected wrongly, as not Seagate?

The drive I installed had Seagate labels and looks genuine.

OS is Windows 10.0.16299.64.

    I think you need to talk to Seagate. Nov 23, 2017 at 0:54
  • The WD3200BEKX is a 320gb drive: google.co.uk/search?ie=UTF-8&q=WD3200BEKX Sounds like one way or another you need to talk to your supplier.

  • It shows up as 1TB on the device manager.Disk Management pane.

  • It had a 320GB Seagate Momentus in this before the upgrade. The install is cloned from the old one with Aomei free edition.

After more time researching this, it seems that the device name displayed in Drive Management and the Device tree is cosmetic,

Device Management mmc snap-in hard drives

and taken from a registry key named “FriendlyName”

FriendlyName registry image

Simply right clicking Disk Drives->Scan for hardware changes results in this:

refreshed hardware changes

and it persists across reboots.

It was populated with the type of the drive of the Refurbisher ‘s OEM pre-installation image. There is even a PowerShell command Set-PhysicalDisk to change it. (Corrected thanks to comment from @Kitet).

Investigation of other values in the same key reveals that it has got the correct vendor/device ID for the Seagate drive.

Hardware ID in registry

Also, Seagate diagnostic tools all show that it really is what it is supposed to be, and is working perfectly correctly.

Seatools diagnostic utility shows correct drive

Whilst it seems that uninstalling the device to let Windows rediscover it is a valid option for some, in my case there is also a extra device driver installed to it, excsd.sys (ExpressCache),

extra driver details

which is for synchronisation with the 32GB SanDisk SSD mSATA cache installed. No doubt that unless I uninstall the external SSD cache first this could cause problems. I would have to reinstall ReadyCache / ExpressCache and repopulate the cache from scratch. I’ve edited the registry FriendlyName instead to avoid that.

This observation also permits benchmark fraud... see this:

Thanks for your comments.

  • The partion name is "Windows". It's not that.

  • SQL injection through the name of your drive to www.userbenchmark,com?

  • "Uninstalling the device to let Windows rediscover it" worked for me on a brand new disk (Western Digital HDD showing up as Samsung SSD). Steps: Device Manager (devmgmt.msc) > Disk drives > right click on the correct disk (check Properties to confirm) > Uninstall device > restart Windows

We don’t need to care what this SSHD can be detected, just care the speed and stability.

SSHD is more like a faster HDD rather than SSD, so I guess system consider the HDD part as the whole SSHD, WDC WD3200BEKX-60B7WTO should be the HDD part’s model

You could contact Seagate for a explanation, but it doesn’t influence the use.

  • It could if the drive is running firmware not intended for use with it. Nov 23, 2017 at 7:38
  • it does have this installed too: condusiv.com/partners/oem/technologies/expresscache from here: pcsupport.lenovo.com/gb/en/downloads/ds104444
