All Seagate and Maxtor-brand SATA, ATA, and SCSI drives for desktop computers and laptop (notebook) computers have built-in error-checking capabilities. Over 30% of all drives returned under warranty to Seagate are in good working order, with no problems found. To save time and the hassle of shipping a drive that may not be defective at all, please test your drive to see if it really is defective.
The first step to test a drive: Please download and run SeaTools for Windows. See a full tutorial in Document ID: 202435.
The tests in Seatools will indicate Pass or Fail. If the drive fails the test, please begin the replacement process at our Warranty Services Page. If the drive fails the test but is out of warranty, you may continue to use it as long as you can, but remember to keep a full backup of your data at all times.
Seatools will test your S.M.A.R.T-compliant SATA, ATA, or SCSI disk drive for media defects, perform a read test and physical head test, and ensure the hard drive is functioning correctly.
If all the tests pass (no trouble found), the problem remains elsewhere in your system.
You can test your drive with CheckDisk. Document ID: 184611 - How to use CheckDisk.
Reconfirm all settings for hard drive jumpers, cables, and ATA, SATA, or SCSI controllers, as well as the operating system. Consult your host controller (motherboard) documentation or system manufacturer for assistance with SCSI termination or ATA / SATA controller capabilities.
-If the BIOS does not recognize the drive, or the drive does not spin up, Seatools will not detect the drive either.
Here are some very useful tools. Start troubleshooting here first. If the drive ends up being detected later, you can then test it using the above article.
-The operating system will not recognize a drive that is not formatted and partitioned. If you need help with formatting:
