This *could* indicate a serious problem and attempts to fix it *could* make it worse. It could also be a minor issue that is easily fixed. Do you have an *empty* spare drive to copy your data to? Ideally you should use 'dd' to take a complete image of sda and work on that instead. dd if=/dev/sda of=/dev/<spare drive> bs=1M status=progress Warning: this will overwrite your data on the spare drive! For this to work properly the spare drive should be same size (to the byte!) or bigger than sda. Before any recovery attempts let's try to find out how your drives are partitioned. Please post the output of following commands from the rescue console. LANG=C lsblk -f LANG=C fdisk -l These are read-only commands so should be safe.
