| | 637 | === Automated test and reassign === |
| | 638 | There are tools that check the entire hard drive and performs reassignment (by SCSI command or by ordinary write) on bad LBAs. |
| | 639 | |
| | 640 | * Seagate's Seachest and openSeaChest provide a [https://github.com/Seagate/openSeaChest/blob/3fc1fb6154f079e6db4cec35bb8971205a68fc10/docs/openSeaChest_GenericTests.191.txt `openSeaChest_GenericTests`] utility that performs non-smart testing by ordinary read and write (as a result, it can do a "selective" test on SCSI). It can be configured to reassign any bad sectors fount. It understands SCSI error-recovery flags and acts accordingly. |
| | 641 | * Also in (open)!SeaChest is the `openSeaChest_SMART` utility. It performs SMART self-tests instead of a generic test, but has the same ability to reassign (getting locations from on SMART error log). |
| | 642 | * There are scripts on the internet that parses `smartctl` output and runs `hdparm`, but with seaChest they should be considered obsolete. |
| | 643 | |
| | 644 | Seagate's tools print out a bad LBA list at the end. Since data on a bad sector is probably already lost, it may be a good idea to fix first and then go back to figuring out what was affected. Doing the fix first avoids futile read-retries by the disk, which can take a long time on disks without Error Recovery Control. |
