You are probably comparing different units. The Start and End of fdisk are reporting sectors, each sector being 512 bytes. Therefore if the LBA is reported by smartctl in bytes, you have: 4,288,352,511 รท 512 = 8,375,688.5 which would place it within your swap partition. I would do this: swapoff /dev/sda2 dd if=/dev/zero of=/dev/sda2 bs=512 conv=notrunc mkswap -L swap -c /dev/sda2 swapon /dev/sda2 and hopefully the problem will be gone when you run the next smartctl test. -- Regards, Mick
