(1)consistency checking

consistency checking 工具：fsck。

二、英语总结(生词：2)

1.counter

(1)counter: contra-("against, opposite")

vt. in an opposite direction(反对，反驳)。

(2)示例

Thus, output to the disk through the file system is often faster than is input for small transfers, counter to intuition(《Operating System Concepts》第 586 页)。

count 和 counter 的词根竟然是不一样的。

2.corruption

(1)corrupt: com-("completely") + rup-("to break")

vt. corrupt literally means "to completely break", over time, it evolves to mean "to change from good to bad"(腐败，损坏)。

(2)示例

If the cached changes do not reach the storage device before a crash occurs, more corruption is possible(《Operating System Concepts》第 586 页)。
