I was not able to few directories and I was showing error saying check with chkdsk. It seems few files from those directories were corrupted. I was also not able to delete those files and directories from command line. I don't know the reason of corruption of files into USB.
finally I have checked USB if corrupted with command chkdsk. And I have found that few files were corrupted with bad links. Those bad links were recovered with command chkdsk.
command: chkdsk /f /r /x
below is the example with output.
C:\Users\hparakh>chkdsk E: /f /r /x
