I have a free agent desk external HD 1TB that I cant get to work in windows 10 (It ran in win7pro). I receive I/O error message (no number detailed), from then on I get message "program is not responding." I have gone to seagate support site for help which is little to none. Computer see's hd but cannot get any response. I have disk wizard and device manager installed from seagate and receive I/O error. I believe the HD was designed for a 32bit system, I have a 64bit system, could this be the hangup? I intend to use this drive as backup only, also have tried re-formatting,will not run. Any info would be appreciated.
