I have a Seagate Backup Plus 8TB Desktop USB External Hard Drive on my Win 7 ASUS G73S laptop . It works well , just for one problem . If I don't access a directory on it for a few minutes , then when I do , the file display can take quite a while to come up , while I get a slow advancing green bar on the top of the Explorer window showing directory path . If I click to resort according to date etc. , same thing . In the Advanced Options of directory properties , I have selected indexing , but doesn't seem to help . Thanks .
