Question about shrinking a BOOTCAMP partition before saving an image backup

I am concerned about the warning I see when I ask to shrink my BOOTCAMP NTFS Partition before saving the backup image. I would like to do shrink to save time making the image, however, the risk of “DATA LOSS” was me worried.

Is the warning referring to DATA LOSS only if I fail to run chkdsk /b prior to shrinking and saving the image?

I just acquired Winclone 6 Standard and have not yet used it.

Since shrinking the partition re-organizes data on the drive, it is possible that disk errors would be uncovered. Running chkdsk /b and having a good backup prior to shrinking. Shrinking the partition doesn’t really save much time since Winclone will only saved used data, but it does mean that you can restore on smaller partitions.
