我有一个 8TB Seagate Archive 硬盘，有一些坏扇区。不过我现在还买不起更换它。我暂时尝试用坏块“修复它”，但这需要很长时间：
# badblocks -b 4096 -nvs /dev/sdd
Checking for bad blocks in non-destructive read-write mode
From block 0 to 1953506645
Checking for bad blocks (non-destructive read-write test)
Testing with random pattern: 14.28% done, 82:45:36 elapsed. (0/0/0 errors)
运行了3.5天，电量才达到14%。应该还需要21天。我究竟做错了什么？有可能让它跑得更快吗？
CPU 和 RAM 使用情况似乎正常。
这是 SMART 报告：
# smartctl -a /dev/sdd
