So what. The data could not be recovered not because of bad sectors

(there
were none before failure, not sure whether there are any now - not

possible to
test it), but because of the bad movements of the heads, and bad

spinning of
the plates.


LOL, since you seem to be an expert at it, recover the data and
then you have proof!


I will if you only tell me how to make the disk visible in the system.

Your drive is dead, the data is gone... move on, you're just
wasting time now.


Most of the data (perhaps even all) is not gone - all plates (or most of

the
plates) are not damaged,


WRONG, they're covered with soot and unusable.

How can you be sure?

The platters are moving quite fast -- thousands of RPMs. When the heads
crash they will generate generate debris above those rapidly moving
platters. Where else would those particles come to rest?

On those rapidly moving platters, right? Do you ever read your posts back?
Anywhere *except* those rapidly moving platters, of course.
They will be shot right into the casing walls where they may be swept by the
rotating air into a particle filter.

And btw, who cares what happens to the heads when you can worry about par-
ticals that escape the particle filter when they shoot off those platters, right?

But that still may not disable access to most of the data in a short period of
time. According to Ontrack opening a disk in ordinary conditions (which I
assume is even worse than those particles from head crash) usually shortens
life of a disk from 100 to 1000 times - it doesn't kill all data on disk
instantly.

That's misleading. The mean time to TOTAL failure once the lid has been
lifted is down in the hours range and can be MUCH less.

Clueless. Can't even setup his newsreader properly either.

Go ahead wacko...pull the cover from a =60GB HD mfg in the last 2 years and
let it sit there and run with the lid off in the average home
environment...tell us all how long it lives. While it's goin watch it
carefully...you might learn something..wear glasses.
