Don't bother even running CHKDSK in read-only mode.

Read-only mode is the same thing as...
In My Computer or Windows Explorer | Right click volume | Properties | Tools
tab | Check Now | And selecting neither option.
or
Running chkdsk from a command prompt with no switches i.e. CHKDSK C:

Reasons for not running CHKDSK in read-only mode.

[[Chkdsk might not accurately report information in read-only mode.]]

[[If you run chkdsk without the /f command-line option on an active
partition, it might report spurious errors because it cannot lock the
drive.]]

[[Using chkdsk with open files
If you specify the /f command-line option, chkdsk sends an error message if
there are open files on the disk. If you do not specify the /f command-line
option and open files exist, chkdsk might report lost allocation units on
the disk. This could happen if open files have not yet been recorded in the
file allocation table. If chkdsk reports the loss of a large number of
allocation units, consider repairing the disk.]]

[[In read-only mode, CHKDSK quits before it completes all three phases if it
encounters errors in earlier phases, and CHKDSK is prone to falsely
reporting errors. For example, CHKDSK may report disk corruption if NTFS
happens to modify areas of a disk while CHKDSK is examining the disk. For
correct verification, a volume must be static, and the only way to guarantee
a static state is to lock the volume. CHKDSK locks the volume only if you
specify the /F switch (or the /R switch, which implies /F). You may need to
run CHKDSK more than once to get CHKDSK to complete all its passes
in read-only mode. ]]

To take advantage of all the Chkdsk parameters, use the command-line version
of Chkdsk.
