Win10 system disk repair tool new command summary

Recently Win10 system disk tool added a new command, the purpose is to make Chkdsk run time more perfect

Add the following parameters:
/scan- run in the specified partition Online scan
/spotfix- Repair live on the specified volume
/forceofflinefix- Bypass all online repairs; all issues must be added to the offline repair queue (eg Chkdsk/spotfix) and need to be used with “/scan”
/perf- Use more system resources to complete the scan as quickly as possible, which may reduce the efficiency of other tasks running on the current system
/sdcleanup- collect and clean up unnecessary security descriptor data, need and “/f” Use
/offlinescanandfix- to run offline scan on the specified volume. If you find the problem, it will fix the error.
In Windows10, Chkdsk has added command parameters for FAT/FAT32 and exFAT partition formats, as follows:
/freeorphanedchains- Free any isolated cluster chains instead of restoring their contents
/markclean- If no problems are found, the volume will be marked normally, even if &ldqu o; /f & rdquo; no settings
In addition, some of the "historical long-term" parameters are also to be understood, such as the above mentioned parameter description "/f", etc., the specific content is as follows:
/f - Fixed an error on the disk. It should be noted that this parameter must be locked to the disk, otherwise the tool will display a message asking if you want to check the drive the next time you restart the computer
/v- When checking the disk, display each file in all directories The name
/r- finds a bad sector and restores the readable information, and must also lock the disk
/x- only on NTFS. If necessary, first force the volume to be unmounted, and all open handles for that drive are invalid. /x also includes the /f function
/i- for use on NTFS only. Check the index items for less strength and reduce the amount of time spent running chkdsk
/c- only on NTFS. Skip cycle checking in the folder structure, reducing the amount of time required to run chkdsk
/l[:file size] - only on NTFS. Change the size of the log file to the size entered by the user. If you omit this parameter, /l will display the size of the current log file
/?- Display help at the command prompt
