You are probably comparing different units. The Start and End of fdisk are |
48 |
reporting sectors, each sector being 512 bytes. Therefore if the LBA is |
49 |
reported by smartctl in bytes, you have: |
50 |
|
51 |
4,288,352,511 ÷ 512 = 8,375,688.5 |
52 |
|
53 |
which would place it within your swap partition. |
54 |
|
55 |
I would do this: |
56 |
|
57 |
swapoff /dev/sda2 |
58 |
|
59 |
dd if=/dev/zero of=/dev/sda2 bs=512 conv=notrunc |
60 |
|
61 |
mkswap -L swap -c /dev/sda2 |
62 |
|
63 |
swapon /dev/sda2 |
64 |
|
65 |
and hopefully the problem will be gone when you run the next smartctl test. |
