Routine Description:
Entry point for chkdsk.exe. This function parses the arguments,
determines the appropriate file system (by querying the volume),
and invokes the appropriate version of chkdsk.
The arguments accepted by Chkdsk are:
/f Fix errors on drive
/v Verbose operation
drive: drive to check
file-name files to check for contiguity
(Note that HPFS ignores file-name parameters).
/x Force the volume to dismount first if necessary (implied /f)
/i include index entries checking during index verification
/c include cycles checking during index verification
/r locate bad sectors and recover readable information
/l[:size] change or display log file size
