我在硬盘的 SMART 统计数据中看到 Hardware_ECC_Recovered 的计数器在增加和减少，我很困惑。

我希望每次 ECC 检测到（并纠正）错误时它都会增加，但到底为什么它会减少呢？

此驱动器的完整智能输出：（无论如何我都打算更换）。

我有负载（大约 6000 个！）mp3，我想根据文件名将其转储到子目录中。目前它们都在一个子目录中。（一些艺术家已经有一些现有的目录，我不想接触这些文件，但是重复覆盖现有文件是可以的）。

我能看到的最简单的方法是根据文件名创建一个子目录，因为这些文件都被命名为 artist.artist.album.track.mp3。

经过一番搜索，我想出了：

for x in ./*.mp3; do awk x="${x}" -F. '{split(x,a,"."); mkdir a[1]; mv x a[1]/}'; done

但是它告诉我存在语法错误和未终止的正则表达式：

awk: cmd. line:1: x=./Dizzee.Rascal.Radio.1.Live.Lounge.03.That.s.Not.My.Name.mp3
awk: cmd. line:1:   ^ syntax error
awk: cmd. line:1: x=./Dizzee.Rascal.Radio.1.Live.Lounge.03.That.s.Not.My.Name.mp3
awk: cmd. line:1:     ^ unterminated regexp
awk: cmd. line:1: x=./Dizzee.Rascal.Ultimate.Streetdance.CD1.03.Flex.Dave.Spoon.Mix.mp3
awk: cmd. line:1:   ^ syntax error
awk: cmd. line:1: x=./Dizzee.Rascal.Ultimate.Streetdance.CD1.03.Flex.Dave.Spoon.Mix.mp3
awk: cmd. line:1:     ^ unterminated regexp

我认为这是因为文件名没有在语音标记中给出，但我不是 100% 确定？

有人可以帮忙吗？如果您也可以打印出进度，还可以加分。
