I thought I would use Eraser to securely erase the unneeded files on my SmartDisk 80GB External HD, after all, it does a great job on my local drive. When I use the right click Windows Explorer context menu to delete a file, the file remains in Explorer, and a popup message says "Task Executed The task ... has completed with errors." Refreshing the view doesn't help. Simply deleting the files within Explorer works fine. But Eraser doesn't appear to do anything. Any help would be appreciated. BTW, I'm using Windows 7 OS with version 6.0.8 of eraser. Thank you.
