User Log On Error

[abhishel777]

Whenever I log on my laptop on win8 I get this error,I don't know why it is happening though it started tpo happen near abpout the same time when this ext HDD started.

The thing is whenever I insert my WD ELEMENTS 2TB ext HDD into my laptop ,the safely remove hardware function doesn't work.
I even tried running RunDll32.exe shell32.dll,Control_RunDLL hotplug.dll but it had no effect so please help me with it.This problem was with my bro's 1TB ext HDD,it started happening with my HDD when I copied some stuffs from his HDD onto mine.

I am linking twom image,the will speak everything else

Please guys suggest me how do I fix both of them,I really will appreciate the help.

Hey there, abhishel777!

This seems to be a software issue, rather than a hardware one. It might be a malware/virus as well, so I'd suggest to backup the data and re-format the drives by completely erasing everything from them. You can use WD's Data LifeGuard to write zeros (erase).
Here's a link to the software: http://products.wdc.com/support/kb.ashx?id=FJroF2
How to Write Zeros using it: http://products.wdc.com/support/kb.ashx?id=F0qFLl

Besides that, you should try this:
Search for Run > once there, type services.msc > Right-click the services icon in the results and Run as Administrator > Scroll to Bluetooth Support Services > Double-click on it and make sure the Startup type is set to Manual and the services are Started
This should get the Safely Remove Hardware option working again.
