I just found some manufacturer specs for my Disk:

For the load/unload specs, see page 40f. It is specified to a minimum of 300000 load/unload cycles, so I'm very near to EOL.
My disk stats:
martin@gwaihir:~$ ./disk-stats -y
PM-related Hard disk health:

                      Load/Unload cycles : 270250 of 300000 (90.08% of life)
    Power-Off retract (Emergency unload? : 27 of 20000 (0.14% of life)
                         Power-On cycles : 3582
          Start/Stop (PM Spindown) count : 10427 of 300000 (3.48% of life)
                          Power-On hours : 6343 of 20000 (31.71% of life)
            Temperatures during lifetime : 13 to 47, manufacturer limits: 5 to 55 (°C)
     Average Load/Unload cycles per hour : 42.606

I have written a little hackish script to generate this, it is attached for anyone feeling the urge to present their stats here, too. (needs smartctl)

Ciao
