If both e2fsck and SMART report no errors, then it
appears that your disk is good.

If you post the complete output of
# smartctl -A /dev/<device>

then we can see the whole story.

If there is more than one disk, are you sure that
you are testing the correct device? (sda,sdb,...) ?

You can check the /dev/disk/by-* directories to confirm which device
is used. Or the output of blkid or lsblk commands.
