If you are cleaning up the folder and files left from a Drive Bender pooled drive, you may encounter an access denied error when deleting the mount folder. The reason for this is that when the drive was pooled, Windows has created it's "System Volume Information" folder which is restricted. This folder is now blocking the deletion of the folder.
First you need to be able to see the hidden folder, using explorer got into the mount point folder, change the view options of explorer and check "Show hidden folder, files" and uncheck "Hide protected operating system files". You should now be able to see the "System Volume Information", right-click this folder and select properties, folder by security. From here add your user account (or an administrator) and give them full control. You should now be able to delete this folder.
Note the are a number of other ways to do this, google "delete System Volume Information".
