How to Perform Basic Tests in Seagate Hard Disk using Sea Tools for Windows
3Sea Tools for Windows can be downloaded from

A menu of the possible diagnostic tests is shown. All 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:
Fix All
Short Drive Self Test (20 to 90 seconds long)
Drive Information
Short Generic
Long Generic (progress in 1% increments and may take several hours to complete)
When you launch the "Short Drive Self Test" (DST) most drives will run a thorough diagnostic routine that is built into the hard drive's firmware. DST is completely data safe.
The "Short Drive Self Test" is adequate for most situations. The “Short Generic” test is similar and tests various areas of the drive. If you need a more comprehensive test then consider running the “Long Generic”, which reads each sector on the drive.
The long tests will take time to complete. Because the long tests read every sector on the drive, the amount of time required will depend on the speed and capacity of the disk drive. The apparent lack of activity often gives the impression that the drive or software has stopped responding.
The “Fix All” tests provide the ability to fix problem LBA’s (bad sectors). There are two options with the “Fix All” tests, “Fast” and “Long”. Be sure that you have all of your data backed up before running any of the “Fix All” tests. When SeaTools reallocates these problem sectors the actual data in a particular sector is unreadable and already lost. Unless the drive is full of data, it is quite possible for the problem sector to be empty of data, anyway.
“Fix All Fast” uses the drive's activity logs to identify suspicious sectors which may or may not be bad. SeaTools goes to each one in the list and if it really is bad the program will try to reallocate that one sector. If successful SeaTools moves on to the next if not successful then the test fails. On average the time is less than 5 minutes.
“Fix All Long” does a sequential scan of the media and discovers any problem sectors and attempts to reallocate them along the way. The time is very long and may take several hours (about 3 hrs per TB).
