It looks like I will have to replace /dev/sdc1 with a new ha= rd drive. What is the correct procedure to do so without loosing my dat= a? > Have a look at dmesg or your system kernel logs for details. Also, use smartctl to examine what the drive itself thinks. Also, try to use dd to read/write the drive.
