Are you copying files from this to a RDP Session?

Yes, sometime I'll use rdp to copy some contents.
Safely remove hardware is only an issue if a file is cached, and not yet physically written to the disk.
I usualy just wait for the led to stop flashing, indicating that write operations have ceased, and pull the drive.  I have not ever found a problem

I do use the safely remove hardware if the copy operation is important - just in case

whats on these drive? any shared data?

what if you logout from the currently logged in user and then try?
weiman99Author Commented:
No share is just a normal pendrive, actually I tried all the pendrive or external hardrive will have the same problem. The default setting for the drive was set to Optimize for quick removal.
ok if still problem persists try scanning them with anti virus may be some hidden faulty program there associated with any running task

scan yours system drive and also this usb drive

Actually not only one usb drive not working but all the usb drive that plug into my system will not be able to unplug. I'll try to do full scan on my system.

You can give this AVG tool a shot:

You could also try one of the AV boot cds:

kaspersky live cd
Download the .ISO file, burn it to disk, and then boot from it. It should ask to download update files, and then scan the system.

Other options:

SUPERAntispyware (free for home use)

Microsoft Security Essentials
