FYI, the parm is buried in chkdsk32.exe and gave the following:

[C:\]chkdsk c: /AuToChEcK
The current hard disk drive is: C:
The type of file system for the disk is HPFS.
The HPFS file system program has been started.
The current hard disk drive is: c:
CHKDSK corrected an allocation error for the file
\HOME\DEFAULT\Thunderbird\Profiles\4i025nx3.default\panacea.dat.
CHKDSK is searching for lost data.
CHKDSK has searched 100% of the disk.
CHKDSK corrected a disk space allocation error.
CHKDSK will place recovered files in FOUND0.
CHKDSK placed recovered data in file FOUND0\FOUND0.
    1028128 kilobytes total disk space.
       3418 kilobytes are in 1169 directories.
     641006 kilobytes are in 10441 user files.
       4464 kilobytes are in extended attributes.
       2048 kilobytes are reserved for system use.
     377191 kilobytes are available for use.
