When I try to do a backup of my main HD to a another internal drive, all goes well. The process stops after several hours and reports an error. It says that my drive is full or alreday written, and that I can empty the recycle bin or delete old data files. My HD that I'm backing up to reports that I have 39GB of available space. Trueimage say's it only needs about 26GB free to do a backup(Image). This seems to have started after I upgraded to Microsft SP2. Don't know if there's any correlation. I've tried about 5-6 times in the last month with no progress. Any thoughts?? Thanks!!
