It's very likely irrelevant to your issue, but running fsck on the
device before mounting it would be a goot idea.

This suggests that something on your system (auto-)mounted /dev/sdc1 to
/media/usbhd-sdc1 in respons to the UDB stick being plugged in.

That's the intended behaviour: The mount point directory gets replaced
with the root directory of the mounted something which has the
permissions (owner, group, mode) recorded on the mounted something. The
permissions of the mount point directory prior to mounting the device
don't matter here at all.
