In the above three tutorials, we explained the basic knowledge of repairing bad tracks, and offered the operation process. The basic principle is to scan bad tracks, add them to G-List and move G-List to non-resident G-List to shield. This process can be time-consuming with low success rate. Restricted by firmware of Seagate F3 hard drives, it takes much time to add defects to G-List and move G-List to non-resident G-List. On the other hand, the capacity of G-List is limited, which cannot hold too many defects. So the success rate is low.
Here we put forward a new scheme for repairing bad tracks in Seagate with MRT - "Shield bad tracks by non-resident list". In the latest version, MRT supports editing non-resident G-List directly. Users can add bad tracks to non-resident G-List directly and recalculate translator to make the modification valid. The operation time is greatly shortened with higher success rate. In the past, users may find it difficult to repair Seagate hard drives with bad tracks. We believe that this scheme will be the most effective and popular scheme for repairing Seagate HDD with bad tracks.
Now we look at the demo, this video demonstrates the basic operation process of shielding bad tracks by non-resident list. Scan the hard drive, we can see there are some bad tracks. Let's try to shield them.
Step 1: Scan the hard drive with "Save bad blocks to the defect list file" checked. If there are many bad tracks, you can check "Skip when bad blocks are encountered" to speed up scanning. Set an appropriate skipping size and check "Record skipped sectors to defect list file" to speed up. There are detailed instructions of scanning skills in the tutorials listed above. After setting the parameters, we can start scanning and record LBA & length of bad tracks to file.
We have scanned the front part of sectors and saved the defects to file. Then we will add defects to non-resident G-List. We can see LBA and length of scanned bad tracks in defect list editor and edit defect files according to the condition of hard drive. For example, enlarge each entry, or merge adjacent entries. These operations are very important as the capacity of non-resident G-List is limited which cannot hold too many entries.
Step 2: Write the scanned and edited defect files to non-resident G-List.
Step 3: Recalculate translator
Step 4: Erase the hard drive.
