This is very early MBR boot sector failure, it should not be related to the fsck issue - but maybe your disk starts to act up? I would start checking fdisk output for the disk - is it still as expected? Does it show a NetBSD partition with expected size? Then compare the disklabel output, does it match? If that is ok, install bootloader again. Also use atactl to check the smart status of the disk. Martin
