Is "Correcting Errors in the Volume Bitmap" something to worry about?

Here is the result of running a chkdsk on my drive in read-only mode:

After, I ran it with the /r switch and rebooted the computer.  I wasn't there to see what the results were but I re-ran chkdsk again and it gave me this same message.
