年级成绩分析:请问电脑说文件损坏，请运行chkdsk是什么意思。什么是chkdsk工具？

chkdsk是系统自带的磁盘检测工具，想要运行的话，运行CMD进入命令行模式，再运行chkdsk + 盘符 比如 chkdsk c:即可进行检测。
一般系统提示的话，说明有文件破损导致无法读写磁盘，可能是逻辑上的坏道，也有可能是物理上，出现这种提示后，一定要注意。或者使用其他的磁盘检测工具检测一下，以防万一。

windows自带的程序，在系统盘winnt或windows文件夹或system32里面。
chkdsk命令：
Checks a disk and displays a status report.

CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C] [/L[:size]]

volume Specifies the drive letter (followed by a colon),
mount point, or volume name.
filename FAT/FAT32 only: Specifies the files to check for fragmentation
.
/F Fixes errors on the disk.
/V On FAT/FAT32: Displays the full path and name of every file
on the disk.
On NTFS: Displays cleanup messages if any.
/R Locates bad sectors and recovers readable information
(implies /F).
/L:size NTFS only: Changes the log file size to the specified number
of kilobytes. If size is not specified, displays current
size.
/X Forces the volume to dismount first if necessary.
All opened handles to the volume would then be invalid
(implies /F).
/I NTFS only: Performs a less vigorous check of index entries.
/C NTFS only: Skips checking of cycles within the folder
structure.

The /I or /C switch reduces the amount of time required to run Chkdsk by
skipping certain checks of the volume.
