My new Book 4TB stopped to show in my computer section after I connect it via usb 3,0 cable to the desktop workstation pc (win 7, 64 bit) it only appears when I connect it via 2,0 port
But 2 passports connected through same 3,0 works fine on workstation. also Book works OK when I connect it to the laptop.
I would recommend installing the drivers for your WD My Book on the workstation from the Device Manager. You can download the driver again from the following link:
Thanks for advices. I have tried to update SES driver 64 bit from link. But nothing has changed after installation.
Also in device manager it writes message that driver for wd is up to date.
I was cleaning my PC recently from dust, unplugged all cables (including this 3,0 blue one) and reconnected a lot of cables back . Also I remember that I connected to this 3.0 cable for the first time wacom bamboo pen & touch tablet to try it with fast port, previously I only connected it to 2,0. After I did these 2 things WD Book stopped to show.
But at least I can access it from different cable.
Being able to access your disk using a different USB cable is quite promising, and indicates the unit itself is healthy. There are times when USB cable degradation tends to be the answer.
