Because i cannot disconnect the drive safely?

I have windows 7 and I've always kept the tags of approximately 5 albums I can not disconnect and I have closed the program and any external hard drive file open.

When i edit approximately 5 albums different i can not disconnect and i have closed the program and any external hard drive file open.

There is an error with temporary files?

Probably there is running another application at the same time, which has write access and locks the files. This can be an indexing service, a virus scanner or whatever else.

Look into the Windows Task Manager, and try to find the suspicious application and close it.
Use a different drive which is not under the control of an indexing service.
