I can't see wasting time dismantling them when you can just do a "dd if=/dev/zero of=/dev/**a bs=1M; dd if=/dev/zero of=/dev/**b bs=1M; dd if=/dev/zero of=/dev/**c bs=1M; clear" and get three done in under just a little while, and then give them to whomever you wish, if they are still functional drives. You never have the reach a GUI, depending on distro, or might not even need to break out the screwdriver (or figure out the HDD removal procedure on a proprietary machine that takes a while to open and get the drive out.
).

You might have it all wrong. I have a friend who would email me (he texts now) videos of gorgeous women undressing and just as you would get to the "moment of revelation"... A squirting banana (if you catch my drift) or something just as repulsive would appear. The craziest thing about it is that he always had stock of different things. Maybe your attorney buddy would send out these pictures as pranks?I provide opinions...

FYI: You got that mixed up. Longs Drugs was its own independent company that started a long time ago, their first store was in the Bay Area. CVS Caremark bought them out a few years ago, into the mega-corp retailer world."Just leave me alone, I know what to do." - Kimi Raikkonen

Leaving sharp shards all over the place, on a range I would like to go back to (if platters of the drive explode) would be my concern...
EDIT: AS PLATTERS ARE RARELY MADE OF METAL ANYMORE.

When the company I work for recycles computers we retain the HD for a month just in case the client needs anything off of them. Then we either remove the platters and retain forever or run BootandNuke 7 pass DOD wipe on them. I'd like to see a computer forensics guy retrieve data from a 7 pass wipe.My Guns:

Disgusting as it is I am sure some creepo has actually probably looked at your wife or kid in "that" way. If you go in public you probably can't do anything about it. There are a lot of creepy weirdos out there. My buddy used to work at one of those little booths that developed film. Remember those. looked like a tiny yellow phone booth. lots of times to pass the time he would look through peoples photos and if they ordered doubles he would keep the extras. if the people came back looking for their doubles he would say they must of forgotten and would order doubles for them again. he kept the nekked pics of people. back then we didn't have internet.Last edited by Rob454; 03-14-2012, 5:23 AM.Comment

They don't "explode", they just develop these really neat holes (well, the back side of the holes aren't so neat, but there you go). Always sweep up after yourself after disposing of surplus drives on the range as fragments of PCB are unsightly and may contain lead and other toxic materials.

Solid State Media does NOT retain information except in two ways: One- the file table and Two- Unwritten to memory.
All you need to do to wipe solid-state media is flip the bits. Unlike magnetic media it does not retain "ghost" images of files in any kind of magnetic field.
Hard Drives can and DO, through many wipes in fact. If data protection is of concern use solid state media because if you want to destroy it all you need to do is a bit flip and the data is gone, FOREVER. No forensics in the world has the quantum technology needed to harvest data off a table wiped and bit-flipped solid state memory device....but their exists also in the human heart a depraved taste for equality, which impels the weak to attempt to lower the powerful to their own level, and reduces men to prefer equality in slavery to inequality with freedom.Comment

Try and bend one of the drives made in the last 10 or so years (non-enterprise-grade?) and it will shatter like a CD, you can see through the platter material like it was a thin layer of something glass-like. This is just the ones I tried to bend in the last few+ years, but it was every one, even 7 year old notebook drives. Using a screwdriver like a punch, they shatter too.They don't "explode", they just develop these really neat holes (well, the back side of the holes aren't so neat, but there you go). Always sweep up after yourself after disposing of surplus drives on the range as fragments of PCB are unsightly and may contain lead and other toxic materials.
Old school MFM, RLL, SCSI, and EIDE drives had metal platters, but not any that I have taken apart in the last... say 6 years.
Granted, this is only the last say 20 or so drives I have disassembled for destruction, being unable to wipe these drives they had to be dismantled and every one shattered. YMMV with different MFRs and grades (enterprise?), as all I had access to was standard grade (5 year warranty? stuff).
A single pass wipe is all that is needed. AFAIK a DOD is just a time waster, and no one has ever, in the history of mankind recovered data from a drive that has been wiped even with a single pass. Dr. Gutman's theory was just that, theory that has never been proven...
You could format with NTFS, ext2, fat32, then NTFS again, and data can still be pulled.
A single-pass "wipe" will prevent "any" Forensics team that exists today, any data recovery team, the FBI's best guys, or any hacker on the planet from getting data (except for data on say a bad sector that was marked bad in S.M.A.R.T. and is now circumvented, but a MFR's Zero disk might fix that?).
Tin-Foil hats are for people who DOD wipe...
Pulling data from a single pass wiped drive has never been successfully achieved (more than just 512byte blocks marked bad).
I have pulled data off of flash drives that have been formatted multiple times, but never mentioned SSDs.
Prove me wrong, and I will yield.Last edited by the86d; 03-14-2012, 1:31 PM.Comment

Formatting a Flash Drive (solid state) only wipes the file-table, it does nothing to the data at all.
This is done with good reason (not TFH), as all solid-state gate has a limited number of times it may be flipped. Flipping the BITS on a flash-drive when it is not needed is wasteful and will result in early failure. Every time I have had a flashdrive die it has always been the memory (not the control) that has failed. Solid-State HDD's that are consume grade have a horrific failure rate.. still. They theoretically have hundreds of thousands of writes (not reads) available to each gate, that is the theory. In practice, every time you write, may be the last.
I have a flashdrive that I currently use to run live-OSes on. It has been high-level formatted probably 20 times in the last two weeks but wouldn't you know the data stays such that I usually end up with 3 live images before I actually have to destructively format the drive so that I can put the next testing live-os on it.
Another great example is that I can use my linux tool that sets up the flash drive as bootable, among other things, and then take it to a windows 7 box and format the thing and have the booting still work. Again, windows does not do a destructive wipe of a flash medium.
Now take that "formatted" flash drive and put new data on that fills the drive up and you will lose that old data, forever. Why? It was overwritten. Gates do not "ghost", it is mechanically impossible. They can get stuck however (classic stuck bit). A dead drive with a bad controller and a living memory chip is a huge security leak waiting to happen. Take a hammer to the chip to remove it forever, otherwise, someone like me can come along and solder that chip up on to a new control and gain data access. Which I have done....but their exists also in the human heart a depraved taste for equality, which impels the weak to attempt to lower the powerful to their own level, and reduces men to prefer equality in slavery to inequality with freedom.Comment
