"Thus if I save the file somewhere else"

I know it will do that, but in a real crash, you wont get that option

"No I can't. That's why we call it "WORKSFORME"."

Ok...lets see how openoffice works, tell me...it does recreate the whole file
right...I mean, it empties the file and then again fills it...right?

"No I can't. That's why we call it "WORKSFORME"."

I'm a physics guy...actually a theoretical physics guy. i.e its my job to
predict changes with some known information. So I'm into these things.

Here, in this case the data in the file first gets deleted and then again gets
refilled, while the refilling process is on, and I remove the flashdrive,
concluding that there is there is no data loss is sheer stupidity. You don't
even need to practicals to do that. In fact in programing, there is no barrier
between theory and practicality...its the same thing.

Practically trying to recreate this is like practically checking a folder for
data without any copy-paste operation in it...now is that not obvious?

However, I did recreate the problem...you just need to have swift hands and slow
the computer down. If you're in vista, there should be an option to set the
power state of the processor (in %...which is actually not true cause there are
usually 3 or 4 power states; but cause its MS, such crap was expected), set it
to 0%...for both maximum and minimum.

Also pls do not use a pendrive with a data transfer rate of
like.......30MBps...the point of using a pendrive is defeated that way. If
you're on vista...do not format it in NTFS...only in Fat32 (since you have no
option for fat16...like with me).

"we have backup mechanisms and file
recovery systems"

Now where is it (I'm not talking about autosaves)?...can someone give me the
path for Linux?...and pls don't tell me its the tmp folder.

"Are you joking? The target disk is no more available during file overwriting,
and you expect that the file being overwritten is still OK?"

Yeah THAT is the main issue...instead of overwriting the file, it can just be
amended, that way there will be absolutely NO data lost for the previously
stored data and the save process will finish in a flash rather than waiting for
half a minute.

"Why should the user assume it? He has tried to store and got an error, why
should he throw his document away?"

If you plug your system from the mains you won't get any errors right? I've
already explained that this will be *simulating* a disaster...no one will plug
the pendrive off all of a sudden while a read/write operation is on...that means
I'm doing it for experimental purposes...and it has succeeded.

Ok...suppose I kill the OOo thread even after the partial save process (i.e
after I unplugged the pen drive) and with OOo notifying me about it...thus
making a an actual disaster sinario.

I restart any of OOo component, and it shows me the recovery option...I click
next...it says the file is corrupt, then repairs it and opens a blank document
which is....I guess around 7kb...i.e reduced from 87 MB to 7 KB...or an empty 
file.

"What do you mean by "recovered"?"

I don't know exactly what happened, but by recovery I mean it showed an option
to recover the file, and I clicked a yes. So this is the recovered file...you
cant edit even one OLE. The second case as per your definition.

As said before, I did produce those void file...should I make a video on how I
did it? We do have such software in the repos though...should be easy.
