I am running Windows XP Pro and installed Norton Ghost two days ago using an external drive j as my backup device. 1. When I went to transfer some files to the bp last night, before they transferred, I got some quick messages on the PC something like "unable to create j:\ . . ." and then I lost the message so can't fully replicate it here. However, it seemed as if Ghost was interfering with BP transfer. I didn't update to the latest beta at the time as I was in a hurry and after the strange unable to create messages, the files did transfer successfully to the bookport. 2. After the files transferred successfully, I replugged in the j drive to the usb port; it is not recognized at all now by the operating system or Ghost. When I plug or unplug the j drive into the usb port, I do not hear the telltale dunk-dunk which signifies that the drive is mounted or unmounted. 3. This morning, I went to update the book port transfer software and got something very close to the following message: "Error dialog c:\program files\aph\book port transfer\perflib_perfdata_694.dat The process cannot access the file because it is being used by another process. abort, retry, ignore (not recommended) or cancel" Can anyone shed some light on possible causes/cures for this situation; I now have no j drive, no backup, can't update the bp transfer software. Thanks for any help. Don
