I bought a new usb external hard drive and formatted it for use (mkfs), but I accidentally specified /dev/sdc instead of /dev/sdc1 (which is how the device showed after powering it). I even received a warning "/dev/sdc is entire device, not just one partition! Proceed anyway?" and foolishly replied "y" thinking the device may have been provided with partitions since it is 2 TB.
So now sdc appears in /dev after powering the device (as it did originally), but not sdc1. And the mount mechanisn doesn't work, although I can manually mount /dev/sdc as
sudo mount -o exec,dev,suid,rw /dev/sdc /mnt/fc
How do I recover from this? Note that there is no data loss here.
Interestingly, I can insert a thumb drive (for example) and /dev/sdc1 will appear and the thumb drive will mount. But if I repower the usb hard file, it is back to /dev/sdc only.
