I always have the problem to eject my external hard disk from my laptop. So I already get used to this error message which was kind of annoying sometime.
The solutions that I always used are by unplugging the external hard disk directly even though I get the error message or turn off the computer and unplug it later.
But now I have a better solution to fight this problem. I am using a free Windows application called the Unlocker, purposely used to delete locked files with error messages.
Other than the above error message, Unlocker also works fine to get rid of the following type of error messages.
and these too :
Cannot delete file: Access is denied
There has been a sharing violation.
The source or destination file may be in use.
The file is in use by another program or user.
Make sure the disk is not full or write-protected and that the file is not currently in use.
How to use the Unlocker?
Once you have the Unlocker installed, simply right click on the file or folder with the error message and click Unlocker. You will see a pop-up dialog box, click Unlock All and you’re done!
Wanna give a try?
