This is really interesting, Cabe, and definitely a needed technology for people who want to ensure they don't leave anything recoverable on an old device, laptop or PC. I don't know about these type of products...is this an entirely new method for wiping data that isn't already being used today?
I think Elizabeth's question is a good one: just how different is this from other software methods, which are notoriously incomplete, vs destroying the drive itself. Can you give us, or point us to, a more detailed technical description of how it works?
The style of "wiping" a phone's data is a sensitive matter. Only user modified space can have the process applied. Some of which is in an OS or hardware protected space. IE:phone's contacts, text messages, etc. So, those areas need surgical style writing and rewriting of bits to cover over the original data. A process like DBAN will overwrite all data it has access to. DBAN, for example, may not get to all of a phone's data, in other words.
Very informative post Cabe. I do just about the same a Charles indicated in his comments: just put the old laptops, cell phones, etc etc in the basement and buy new. I was just made aware of a company in my home town that provides a service wiping PC hard-disks and cell phone memory. It's (apparently) doing a booming business. They also repair cell phones when damaged. It's a retail establishment so I paid them a visit to see what they were all about. I was amazed and the business they do wiping memory. Obviously this is a definite need prior to tossing, selling or giving electronics to other people. Great post.
I'm not surprised that company is doing a booming business, bobjengr. I've talked to countless people who say they're afraid to get rid of their old electronics, especially if they used them to buy something online.
Unfortunately, I can't just put gear in the basement, per say. After letting a bunch of old computers and laptops age from being worth a little money to garbage, I don't like to house tech anymore. I like to sell what I don't use, and buy the next new "whatever."
However, I have destroyed harddrives when I worked in medical IT. That is always an option.
PS. I still have a 286, 386, and 486 PC in storage. The computers of my youth, to be exact. Old video game consoles I can't seem to part with. A few webOS based cell phones, I just like to have as backup. So, perhaps I do follow your suggestion.
Most of those old devices I keep are within 20 feet of me right now. So, it is more like "try not to notice every day."
However, with programs like DOSbox, I am considering recycling the old PCs. Though, perhaps they are becoming collector's items now. My father sold all his old 12" foppy disk based PCs and such on Ebay not too long ago for quite a bit. The original boxes fetched a healthy price on their own.
Cabe, I'll have to try this out. I hate to admit it but I have a couple old laptops and phones where this has been the problem in getting rid of them. Normally I have damaged the hard drive to make sure that no one could get personal information but this is obviously a much better solution. Thanks.
I don't think this technology is designed for computer hard drives. Their marketing blurb indicates it is for phones and possibly tablets which use flash memory. I think the only reliable way to prevent data from being recovered from a disc drive is to spike it, then give it to your grand-children and ask them to take extra care in handling it, then burn-it. Flash drives are designed to be fairly robust and until now there were few if any product capable of completely defeating the built-in protection. If you dispose of your cell-phone or tablet, you cannot be absolutely sure the data is erased using any of the device's controls, so this product is a significant step forward.
I do not believe DBAN can effectively wipe personal data off cell-phones. IE: contact info, text messages, etc. The free storage space, maybe. There is no other way I have seen that can NSA-level clean cell-phones/smartphones. I often read of people buying phones and such off Ebay and restoring all the "deleted" files. So, I never plan on selling a phone like that.
This BlackBelt option is definitely filling a need. I am surprised others are not joining the game.
Cabe, I was not inferring that dban is intended for phones. I was replying to the posts about old laptops and PC hard drives being stored just to keep the data safe. At least I thought that was where I replied.
I researched dban a few years ago when I needed to wipe a PC hard drive for my employer. That was one of the best free versions available. From all that I found it can be comparable to (quite) expensive commercial versions as well government methods of data wiping. It depends on the level of erase that you desire and how long you want it to take as to how effective the wipe. It is not as thorough as a government wipe, but pretty darn close for a freeware application and more than likely good enough to recycle your HDD.
Cabe - So are you saying that DBAN isn't even that great? Your recommendation for running it 10 times makes me a bit nervous. I'm thinking going back to the old sledge hammer is the best approach. (Actually, drill press, but the sledg hammer makes a better visual).
DBAN is great. Running it 10 times would definitely wipe a harddrive enough so the average, and even adept, user would not be able to get data off the drive. Perhaps the NSA could get recover whatever is on there...
However, DBAN is currently not set up to use on cell phones. Perhaps in the near future.
And yes, the hammer to the drive is a good idea. Even those platter pieces could have recoverable data on them. Use this method as a last resort.
To really get rid of files, at least to the point where they are not recoverable, fiurst erase them, then save new data on top of them, then run the disk optimizer. After that, erase the files agin, run the disk optimizer again after all of the stuff is erased, then save new stuff, such as large picture files, until the memory is full. By rearranging the memory segments and then writing new stuff in them, and doing the whole sequence a few times, anything that could possibly be recovered would be small chunks of a file at most. Sort oof like the "shred and burn "process, except less pollution.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
