Backup Plus and GoFlex Desk Thunderbolt Software
The Seagate Thunderbolt adapter driver is only needed if you are using 3TB or 4TB drives with the Thunderbolt adapter and plan to change drives with other GoFlex adapters (such as USB or FireWire). If you don’t intend to use the drive with other adapters it can be reformatted and the software is not needed.
FreeAgent GoFlex Software
This is an updated version of software for Windows 8 users.
SeaTools for Windows
SeaTools for Windows tests SATA, USB, 1394, ATA (PATA/IDE) and SCSI drives. It installs onto your system. SeaTools for Windows is completely data safe. If the drive passes SeaTools for Windows, your troubleshooting can move to other areas.
