Wow!!! You open up your hard drives to work on them? Must be you have a 3-stage cleanroom laboratory and noble gas chambers in which to do that. crazy


does best buy or any other computer repair place have a cleanroom and gas chamber?

if they did it would cost far more to repair a hard drive than the cost of the entire computer

LOL

check youtube for others performing the task grin

you are fully aware that a hard drive is not completely sealed

it has an opening in it to allow air in to stablize the pressure when the disks are at high rpm

there is a filter on the opening

but you knew all that

in simple terms it is like the old style record player but it has many stacked disks

if you ever saw a juke box with stacked records it is the same principle

when a song was selected the stack would open enough to allow the needle arm to move in and play that one record

the hard drive has stacked disks (look like smaller music cd's) with spaces between them for the read/write head (needle arm of old record players) to move inside them

there is a small motor that drives the entire stack of disks

there is a read/write head that you could compare to the old record player needle arm

some hard drives are single density and others are double density

the ones with single density can only contain data on one side of the disk

the double density can contain data on both sides of the disk and there are two read/write heads on opposite sides of the arm

the double density allows for more storage of data in about the same amount of space

1) Since when did you start working at BestBuy?

2) Anyone NOT working in a cleanroom and wearing a "bunny-suite" is a hack, and just as likely to create more problems than they fix (that includes BestBuy).

3) The cost to repair a hard drive is already more expensive than replacing one. It is NOT however, more expensive than an entire (half-decent) computer.
https://www.bestbuy.com/site/geek-squad/...cat748300502324

4) Most new high-cap/high-speed drives are indeed sealed (welded) and helium filled.
https://www.technologyreview.com/s/52101...dy-for-liftoff/

5) Wipe vs. Overwrite... It doesn't matter whether or not you or anyone else is ignorant of the correct terms. They are, in fact, different processes with entirely different results.

6) Truly eliminating drive data is a complicated, multi-step process. I should know. I was once responsible for carrying out FBI/DOD-level data sanitization. I've worked extensively with all associated equipment and methods listed below. And yes... to fully degauss a drive, you need to be protected from intense magnetic radiation by lead-lined walls. Drive "destroyers" are the second part of the security equation.

Kinda early for you to be smoking so much crack, don'tcha think?

At least you've finally stopped pretending that you know anything about this subject. -Kudos!

It depends on the specific location. Not all stores participate in e-waste processing. Many do not take computers at all.

Their regional headquarters (Rochester) will have a list of participating locations. But good luck getting through to them. Usually best to inquire in-person.


Here's a list of many NYS Electronic Waste Collection Sites by county:

Yeah, not so much...

Gotta have the last word huh????......and I am going to point out that with a local landfill that its going to be missing into a mound of earth extremely quickly.

If you are worried that the government man is going to find your disgusting collection of Japanese adult films then you have a worse issue on your hands.

No, but apparently I DO need to disinfect the misinformation contaminating this thread.

As for your Freudian broadcasts... welll, they speak for themselves. wink

Now don't be melodramatic. I posted the facts and put it all in perspective for everyone to determine for themselves, what level of security is appropriate for their situation. If you and/or bz are having problems deciphering that much, then both of you have worse issues on your own hands.

Cheers!

Here is the most simple answer to give, do you throw your mail away including bank statements, old bills, etc. that have personal info on them after ripping them up? Yes.... Hit the logic board on the back with a hammer and toss it.

No.....have a professional 0/1 wipe it several times.

Lets be serious folks no one in this area will spend the time and man hours trying to take apart and recover your data from the landfill. Your data poses more of a risk when you use your computer.

Speaking of being "serious", overwriting several times offers absolutely no additional benefit than doing a single pass. It's a belief based on faulty, incomplete research that still garners unwarranted traction to his day.

A single-pass pseudorandom overwrite is all that is required. It does not however, make your data 'safe' from recovery. Merely more likely to be safe.

Atomic force microscopes typically cost (new) in the tens of thousands of $$$. Used, fully-functioning education models are readily found for sale on the web for only a few hundred dollars. While your data may be unlikely to be extracted using such tools, it most certainly is not safe from such processes. And use of such second-hand machinery is far more common than you may know. I know because I was an international wholesale broker at one of the country's largest electronics e-waste facilities. We sold them in pallet lots of hundreds.

Simple answers, while indeed 'simple', are rarely accurate. Metaphors even less so.

Besides, electronics aren't allowed in landfills.

So, remember... just because you're paranoid, doesn't mean they're not out to get you. wink
