WD My Book Essential shows as My Book 1140

Just bought a WD My Book Essential 1TB.

I don’t need WD SmartWare as I use Acronis for backup so the software isn’t installed.

Connected  the drive to my Windows 7 64bit Lenovo laptop.

I have now 3 WD drives :

Internal 500GB WDC WD5000BPVT

External My Book 1TB WDC WD5000AAKS (2x500GB Raid 0)

External (new) My Book Essential 1TB WDBACW0010HBK-01.

After connecting the new 1TB Essential drive I got a Lenovo update to install WD SES device driver which I installed.  The SES driver appears in Device Manager under WD Drive Management Devices.

There is no entry  under c:\program files\western digital\ses driver.

The new drive is displayed by Windows 7 device manager (and other applications) as My Book 1140 USB device.

SIW application displays the drive as WDC WD10EARX - WD My Book 1140.

What shoul I do to get the drive to be recognized properly ?

If the drive is working fine this should not make any difference

you can rename it to whatever you want
