How to find out what is holding me back from disconnecting an ext USB drive?

[tracerit]

It's bugging me that whenever I try to safely remove my eternal hard drive, it'll say something is using it but i know it's not. i end up just unplugging it.

is there a way to find out what program is using it?

also is there a widget or something that i can put on the desktop to safely remove the hard drive? clicking on the bottom right icon to do it there's a lag that's annoying.

explorer
search indexer
antivirus
sometimes try ejecting it 2-3 times in a row.

what do you mean by all that? are those options or steps?

C heck Device Manager, drive properties, Policies, and which check box is active . . . Optimize for Quick Removal or Performance. That determines whether or not write caching is in play for that drive.

Try that, maybe? I've never tried using it on a drive, but it works great for files and directories.

Do you have any media sharing services setup? Windows Media and Winamp are two examples.

Do you have any programs like browsers or instant messengers that could have open file handles from say opening/saving files on the drive?

Oh and try Process Explorer.
