My housekeeper accidentally deleted all the messages (including my 2
year old daughter's) from my Uniden 900 MHz 378 series telephone
answering machine. Any possibible way of getting those messages back?

There are several good books about time travel.

No. Your unit does not use tape to record messages. It uses digital
memory devices. Only under the most extraordinary circumstances would
there be a non-zero chance of recovering anything. If those
circumstances existed, I'm sure you'd have mentioned them.

Well, it has been shown recently that RAM chips can be read after removing
them from a switched off computer, and the data retrieved. This is usually
done by cooling the chips with liquid nitrogen before removal. The memory
holds the data long enough to be read off the chips, despite current
beliefs/data about how long memory chips keep their data. (often a few
minutes after the machine has shut down - much longer if cooled down).

This has quite serious implications as far as computer security is
concerned, as the RAM often contains copies of any data that was last used,
and is often not encryted, despite any encryption used in the machine.
(This is an oversight of some encryption systems I believe)

In your case it may be possible to remove the memory chips and copy them,
then you would need some sort of undelete software, and you may be able to
get your messages back. But somehow I don't think you are going to try
that.

Not so much an oversight as a necessity. In order to VIEW or [in most
cases]manipulate encrypted data, it MUST be decrypted.
That is done [usually] in RAM.

The 'oversight' is that most operating systems don't clear that data when
normal shutdown is down.

In the case of an abnormal shutdown, the hardware would have to be
specially designed to wipe itself.

Considering the number of bugs that have been found in hardware and
software, I suspect that the chances of a 'completely foolproof' protection
system are very small.
*** a small thermite charge triggered by ANY abnormal shutdown WOULD
probably ensure security but would also ensure very short computer
lifetime.


In your case it may be possible to remove the memory chips and copy
them, then you would need some sort of undelete software, and you may be
able to get your messages back. But somehow I don't think you are going
to try that.

I suspect that by the time the erasure was discovered, it was much too late
for such.

The messages are stored in flash memory which is EEROM, not RAM.

Mine uses RAM, there's a 9V battery backp, lose that and all the
incoming and outgoing messages are lost. I finally modified it with a
resistor to charge a 9V NiCd battery.

I've never seen that, but I have salvaged several flash memory chips

I picked it up for free years ago, it's a fairly early one, if I had to
guess, I'd estimate it to be mid 90s. Flash certainly makes more sense,
at least at modern prices.

I have one from the late 90's and it uses RAM as well. If you unplug it
without a backup battery it looses everything.

Greetings -Senin..

Why is your housekeeper even close enough around your answering
machine to 'accidentally' do this?

Solution, make it clear to either stay away from personal electronics
and especially your telephone answering machine or she will be
replaced. Simple as that.. Otherwise, this is likely to happen [yet]
again.

The "oh, sorry about that.." routine doesn't cut it unless she has
been with you for years and this just happened out of the blue. I will
tell you that the housekeepers love to tell stories like this with
other housekeepers about how they do such things for jollies.. Senin,
IF it was truly important to you, then it's time for the bill payer to
be stern, otherwise, she won't consider it any more important than you
do!

Cheers,
Mr. Mentor

By the late '90s Flash was the cheaper way to go. By 2000 I was using
i MB Flash in military grade communications equipment, and they were
almost as cheap as the much smaller static RAM used in the products.

How do you know it wasn't a low hanging power cord that got caught
with the vacuum cleaner, or some other stupid accident that could have
been prevented by a proper installation? Or even a worn out outlet that
let the wall wart fall out from the vibration? You are quick to condemn
people with little or no information.

Nice guesses, but dBc obviously knows nothing about cleaning.
Housekeepers are supposed to clean things (by definition,) including
answering machines. They gather dust and dirty fingerprints just like
phones and keyboards do. It's easy to push buttons randomly when you're
cleaning something like that.

Speaking as a white south african, it's amazing what foreign nationals
will say to you about those filthy *racial group/sex/culture* because
they just assume you're the same bigotted pig as them. So far, in my
limited experience, the brits lead the way (and deny it the most

be far more careful about what they let slip. The whole thing is both
offensive and depressing.

Trolls, however, are fair game. Death to trolls.

I'm sorry if you think that I think all White South Africans think the same.
The tone of this posters reply just doesn't sound like it comes from Europe
or North America, so I made a joke, attempting to make fun of this ludicrous
and outdated type of predudice.
I have met some "privileged" White South Africans, not many, but was quite
astounded to hear certain attitudes that seem to be buried in the culture,
that you just don't hear in Europe. Similarly, I have met quite a lot more
Israelis while travelling in India, and again was astounded to hear certain
attitudes toward whole races of people, not least the Indians whose country
they were a guest in.
Now that is not to say that I think all Israelis have a bad attitude, but if
I hear a similar attitude from someone, I may liken it to the attitudes I
have experienced when meeting travelling Israelis, or White South Africans
for that matter. In this case I heard something and made a joke about it, I
didn't mean to offend anyone, except those with thise sort of attitudes.

I know the British also have some very arrogant attitudes, and I have to say
that when I am abroad, I am often embarrassed to be British, to the point
where I avoid other British people. I think "we" deserve any jokes you can
throw at us to be perfectly frank.

I dunno, humour is humour. There's a great debate about whether Holocaust
jokes are acceptable or not, or at what point do we say "now it's OK to make
the joke, last week it wasn't".

Ah don't stress: it's been 24 hours, I'm over it! I find people who moan
about being victims of racial stereotyping extremely tiresome and now
I'm one of them. I also happen to believe that *ism is a natural state of
mind for ALL human beings, and we have to work very hard to overcome it.
And finally, I didn't have such a ****ty day at the office today, so I'm
less
likely to go looking for things to be offended at

And now that we're friends again, let's drop the subject - don't wanna hurt
the groups signal-noise ratio anymore than I already have.
