Hi,

Does this mean the HDD is going to die soon? I had several problems with it
already, but they would always go away after moving the disk physically
by just some milimeters (some bizarre interaction.)

I am getting the usual several second "freeze" after each read error.
This is i386 running -current as of 13th April (no, I don't think I suffered
from UFS2 problems).

I knew it had to be finally replaced some day, but I'd like to make sure
whether it's gotten really bad now.
