The Speccy report shows that your Seagate HDD is failing. To double check it I'd like you to run the Seagate Tools for Windows.
Segate’s Seatools for Windows is really easy to use. It enables the Windows users to probe the performance of their disks and evaluate their current state. The diagnostic tool performs several basic tests that help to determine the health of the hard drive.
It can test all types of internal drives including SCSI, PATA, SATA, etc. Besides this; it can also test external drives (USB or FireWire). If the drive passes SeaTools for Windows, troubleshooting can proceed to other areas.
To test the software for its functionality, simply download and install it on your Windows computer.
Once you run it and select the drive to be tested, a menu of the possible diagnostic tests is shown. With the exception of Long Generic which offers the option to repair sectors on USB external drives, all other Basic Tests are data safe, read only tests. Select the tests that you would like to perform. The test will begin immediately.
These tests include:
• SMART Check
• Short Drive Self Test: 20 to 90 seconds long
• Long Drive Self Test: may take up to 4 hours, progress in 10% increments
• Drive Information: can be saved to the Log file
• Short Generic: three-part test
• Long Generic: progress in 1% increments, sector repair option for USB external
• Advanced Tests.
It is important to note that if the above procedure fails you may have to consider replacing the non-functional hard drive with a new one.
