Yes, pretty much as expected there.
You can safely now try this:
./hdparm -N1953525168 /dev/sdc
If that works, it will have temporarily restored access to the entire
drive.
Then you can try to make it permanent by doing this:
./hdparm -Np1953525168 /dev/sdc
If *that* also works, then reboot and things should be fine,
unless your machine BIOS changes it back again on boot.. :/
If either of those *fails*, then it is because your BIOS (or possibly
the system startup scripts) have "frozen" the configuration
to prevent changes. Dunno why they would do that, but it's possible.
In which case, you could move the drive to another machine temporarily,
and then issue that same command there.
..
Or just hot unplug/replug the drive and try it again.
That should also work, assuming the driver for your controller supports hotplug.
