I assume that you meant storage driver since your title indicates that -- did you try running SeaTools to check the drive.
You can get that here: http://www.seagate.com/gb/en/support/internal-hard-drives/consumer-electronics/ld25-series/seatools-win-master/
Also if you don't have the software/drivers that are usually in a file on the disk, you can download them from that site.
