Essentially they drop off causing the system to die, then an attempt to reboot brings up nothing for the user.
The drive spins up then sits there with the "tick of death". It sounds like the drive heads are jumping back and forth inside the drive. They are all doing the same thing with regards to the failures.
In some cases we can get data off of them, but in most we cannot. Swapping the electronics from a known good drive produces nothing. Even freezing them seems to get no where. It looks like there is an internal component of some sort failing in the drives.
The sizes we have been seeing are the following:
- 120GB ST3120021A, ST3120023A (PATA)
- 160GB ST3160023A (PATA)
- 120GB ST3120026AS (SATA)
- 160GB ST3160023AS (SATA)
This situation demonstrates why it is so important to have good backups in place.

In this case, 7200.7 which are an early model.
We have been seeing a number of 500GB 7200.10s with problems like the click of death lately too.
So far, I agree, the 7200.11s seem to be coming out of the box in better health than the 7200.10s have.
Thanks for the comment,
Philip
