You are welcome that's what I'm here for.
You'll need
Seatools for your Seagate drive. Download the DOS version and create a bootble floppy or CD. Boot to it and run the diagnostic. If it reports any errors or fails, then you have a problem with the drive.
Post the error code back here, or call Seagate Support ad tell them what the error is and see what they recommend.
Alot of times refreshing the drive with a deep format will clear up the errors. I recommend using
DBAN You would need to greate a bootable floppy or cd to use this software also. It's a slow process but is a very good software for wiping a drive clean and start anew.
Post back with your results and or questions.
