我需要帮助解释 smartctl 的输出。我做了 smartctl 检查，因为本周断电后，我的 ubuntu 系统在启动 infsck 时首先出现一些错误，然后出现蓝屏。smartctl 的输出是：

Error 1 occurred at disk power-on lifetime: 2383 hours (99 days + 7 hours)
When the command that caused the error occurred, the device was active or idle.

我关心的是：
SMART overall-health self-assessment test result: PASSED
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE
1 Raw_Read_Error_Rate 0x000f 114 099 006 Pre-fail Always - 59491560
这看上去似乎是一个很大的价值。
4 Start_Stop_Count 0x0032 099 099 020 Old_age Always - 1921
功率增加和减少很多？
7 Seek_Error_Rate 0x000f 067 060 030 Pre-fail Always - 6246697
再次，看起来很大。
9 Power_On_Hours 0x0032 098 098 000 Old_age Always - 2405
查看下面的 ATA 错误时使用 2405。
184 End-to-End_Error 0x0032 099 099 099 Old_age Always FAILING_NOW 1
这很可怕，是吗？
SMART Error Log Version: 1
ATA Error Count: 1
Error 1 occurred at disk power-on lifetime: 2383 hours (99 days + 7 hours)
2405-2383 = 自 ATA 错误 1 以来已过去 22 小时
Error: UNC at LBA = 0x0007fdd8 = 523736
它尝试读取磁盘块 523736，并出现 UNC 错误。
建议：（YMMV，不负责，...）从 Live USB/CD 启动并fsck再次运行。
开始计划更换磁盘，确保您有可以恢复的最新备份。等待 s fsck，我会担心。
