Hey, thnx for the help willsko87. Both the Norton and Recycle Bin method did not help me. However, while reading through the different posts, someone posted the solution for MY problem.
Here are the steps for those of you who wants to know:
1. Go to My Computer then right click on the external hard drive and click on properties.
2. Click on Hardware Tab, select the external hard drive and click on properties
3. Go to policies Tab and you'll see two choices
3a. Optimize for quick removal : This basically states that you CAN unplug your external hard drive without using the Safe Removal option. (for ppl on the rush)
3b. Optimize for perfomance: This is what you need to chose if you want to use the "Safely remove harware" option. It is also the recommended one.
Hope this helps for anyone having the same problem as me =)
