Yes, deriving from the values in the screenshot, the CHS geometry under FreeDOS is detected as 16 heads, while it was formatted with a head count of of 255.

If the CF as a whole is less than 528 MB in size, 255 heads seems rather high, and 16 heads as reported by the XT-IDE BIOS is the "standard" one for such a disk size.
