Wheelie Bins

[furrybean]

Hey,
How bad is it to put an old monitor in the wheelie bin?

[Saint Matt]

Chuck it in the countryside like eveyrone else!

















Joking! Do you not have a tip local?

[jonboy]

Not too bad, you've just got to be careful it doesn't tip over as you wrestle getting it in :lol: .

[furrybean]

Nope it sits quite snug in the top. By the time they realise its in there it'll be in the bin wagon. There arent any tips around here. I could drive 15 miles to the nearest one I guess...

Or just leave it where it is.

Might as well leave it were it is, what will they do..put it back :lol:

You can take it to the tip then

[kwak zzr]

cover it up with something so they cant see it.

[pegasus]

why not juust ask the binmen if any off them wants it :)

Toxins: Old CRTs may also have used toxic phosphors, although that is much less common today. An implosion or other breaking of the glass envelope could release these toxic phosphors. Because of the X-ray hazard, the glass envelopes of most modern CRTs are made from heavily leaded glass. The lead in this glass may represent an environmental hazard, especially in the presence of acid rain leaking through landfills. Indirectly-heated vacuum tubes (including CRTs) use Barium compounds and other reactive materials in the construction of the cathode and getter assemblies, normally this material will be converted into oxides upon exposure to the air, but care should be taken to avoid contact with the inside of all broken tubes. In some juristictions, all discarded CRTs are regarded as toxic waste.

High voltage: CRTs operate at very high voltages. These voltages can persist long (several days) after the device containing the CRT has been switched off and unplugged. Residual charges of hundreds of volts can also remain in large capacitors in the power supply circuits of the device containing the CRT; these charges may persist for weeks. (Modern circuits contain bleeder resistors to ensure the high-voltage supply is discharged to safe levels within a couple of minutes at most.)

Implosion: All CRTs and other vacuum tubes operate under negative pressure so that air and gas molecules will not interfere with electron streams. CRTs have large viewing areas and proportionally larger bells required to accommodate the deflection of the electron beams to the rear of the screen. As a result, these highly evacuated glass bulbs have a large surface area, with each and every square inch exposed to atmospheric pressure.

So you are happy to present the bin men with a risk than make the effort to drive all of 15 miles to dispose of it safely? :wink: :P [of course thats presuming by old it is a CRT monitor]

Ok, seriously, monitors are not good environmentally to be just dumped. They can be a hazzard if not disposed of properly. Do the right thing and take it to the dump. Its only 15 miles not 150. :)

pretend your a rock star and chuck it out of a hotel window :lol:

















legs it for cover 8) 8) 8)

SMASH IT TO BITS AND MAKE SURE THE DRIVE IS DECIMATED otherwise it is only to easy for people to retrieve any information you have put on there during its lifetime----------Re telly program regarding PC's not being destroyed at dumps but being sent to India

[Red ones]

It's very naughty.


Why not just take it to the local Household Waste Recycling facility?

Hes talking about a MONITOR not a base unit with hard drive. :roll:

Smashing a MONITOR to bits can be extremely dangerous and not something anyone should freely advise. :?

[Red ones]

I just remembered - I acually meant to write some facetious....



Wheelie bin? I can't even wheelie my SV!

[Carsick]

Re the residual current, it does hurt but it's not life threatening, unless you have a severe heart condition or something.
Don't ask how I know this.

[lynw]

Oh and just for justmacsv650, there is another way to wipe your drive securely without having to remove it and destroy it.

If you find a wipe program that wipes drives to the US DoD standard [ie wipes it 7 times and overwrites every sector with a character] that would be sufficient. Its what we used to do and far less dangerous or less effort than physically destroying equipment.

It IS impossible for even the best forensic software to retrieve from that. Simply formatting the drive once is not.

[medwaysv]

is there a sense of humour bypass to this thread somewhere :lol:

I'm not sure that is correct.

As I understand it, for long-standing data, the flux will create a shadow, so my changing the alignment of the heads, the data can be read.
To do this, you need to take the drive apart (and remember that a particle of smoke dust can knock a head out of alignment), so it's hardly trivial, and undoubtedly expensive. More than your average eBay'er would be willing to spend.

I thought I had an article about this bookmarked, but I can't find it. I think if you read the article about Spinrite 6 on Steve Gibsons website it may make references to this.

I've never tried this, so I don't know if it's true - it could be complete b*llox. It sounds feasible to me tho.

[ethariel]

Even wiping a HD to the US DoD standard is no longer 100% effective. Just pop it open and smash the platters to bits with a hammer.

Slight misunderstanding on my part,I thought he was changing his whole system
I do know that there is an over ride prog that deletes all the information[As use by banks and corps] just that I was really surprised that councils do not destroy PC,s but are sending them to India and Nigeria for re-cycling where people are downloading the information and using it for unlawful purposes My simple mind says to me that if I have smashed it [The Tower] and destroyed the drive somebody would be hard pushed and desperate to retreive info from an unknown source

I know what youre talking about but the technology required to do this is stuff you would have in a university advanced physics lab, its not stuff you could just go to dixons and get the gadget and do. :wink: :P :lol:

And its not entirely a 100% guarantee to get the right reading either.

Ethariel, interesting to know that. Things obviously moving on since I did this. Interested to know how this works and why 7 wipes is no longer safe.

[SoulKiss]

Londonsers may have heard of Freecycle - basically an online servie - kinda like loot, but you dont charge for it.

Problem is - no-one wants CRT monitors these days - so my mate who had 2 17" monitors to dispose of found that, well let me paste his email he sent out about it.....

"2 x 17" monitors. Impossible to give away on Freecycle or elsewhere. Left on the pavement, gone in 20 minutes."

So Chavcycle them.

And as for Hard Disks - keep em all forever and when they break - 12lb Sledghammer.

Or screwdiver - take the platters out - make even better coasters than CD's - or because of the metal they are made of, make good mirrored wind-chimes - :)

:lol: Beautuful word that. Never heard of it :wink:

7 formats never was enough to remove the ghosting. It was only ever considered "secure enough." IMO, it still is. However, IMO, just 'low level' format the drive & (as you said) write 1 char to every sector of the disk (although, depending on the sector size, 1 char may not fill 1 sector - but in principal all good).

A few years ago I was working for a company that was being paid to investigate the possible affect of TEMPEST attacks (the art of viewing a CRT, from miles away). So long as you have a 'clean room' and the right hardware (which can actually be purchased from B&Q), it's actually pretty trivial to get data from an old hard drive.

For those paranoid enough, your local breakers yard should be sufficient. They have a nice way of picking cars up (electro-magnet) and dropping them in a crusher. Minimal effort, all data erased beyond the "7 wipes" principal, quite a lot of the shadowing goes as well, and should anyone really want the data, they have to make the discs flat again so they balance in a rotating vacuum. But then, if you need to resort to this kind of tactic, I'd be expecting a knock on the door in the next few mins.

(I do know a guy that has a nice setup. He's designed & built what is esentially a microwave in the doorframe. If you don't open the door & press the right button (hidden obviously), the microwave comes on. It's not enough to cook you, but it is enough to generate a small EMP.)

Baph,

You sound like the sort of guy I bumped into on a Sybase course many years back. At the beginning of the first day, the instructor sent a list round asking everyone to write their name down, the name of their company, and their email address. These 2 guys (who always seemed to disappear at break time) just wrote "Government" for their company name. The instructor noticed this and said "What government department - can you be a bit more specific?" (just wondering I guess). They said "No, just the government." It was rather funny really.

I bet those two would have got data back from this drive once they've finished their daily Sudoku!

:-)

Funnily enough, not that far from it. I used to work quite a lot with cryptography & telemetry. I have also advised a collegue in the past about what he should do with audio recording equipment after it was taken somewhere it shouldn't be. He tried to forward a copy to me, but lets just say that I knew the source, and just refused to accept anything to do with it (other than telling him how to 'safely' dispose of hardware).

My job now is nowhere near the security level I've had in the past, but even now, my manager has left the armed services after being involved in communications (as he puts it 'behind the enemy lines'), and isn't able to name the specific section of the forces he was in. All I know, is that he was mainly developing photographs in tents, in the pitch black, and that he trained as a sparky.

Anyway, this is starting to get de-railed lol.
