I have a T41p and I am one of those unfortunate ones whose drive failed. I was working on a train when it happened, so I guess due to the vibrations, the active protection feature was just activated when I shut down the computer. So, this info from IBM could explain why it happened.
Funny thing is, here in Germany, absolutely nobody from IBM seems to know about this problem. Moreover, they told me, that this doesn't happen frequently, quite on the contrary, that I am the only case they know of.
Great thing is, though, that they can't find another drive. Seems there isn't one in all of Europe and the one the ordered from the states also failed during testing

So I am waiting for 2 weeks already, with no end in sight!
HESDog, could you keep us updated, about when the firmware will be out and where do get it? Would be greatly appreciated.
