Introduction: How to Hide Stuff in a Floppy Disk

Nobody uses floppy disks anymore so why not turn that unused floppy into a convenient way to hide your things from prying eyes...

So today I present:

Step 1: Dissasemble the Floppy

This is relatively easy, just make sure that you don't break the disk. I used a pocket knife and cut the places where the corners are held together. Put your disk aside for now.

Step 2: Find the Things You Want to Hide

Now you find something you want to hide, in this case I wanted to hide an SD card with some sensitive information (see picture). You can use anything that is thin enough.

Step 3: Make a Hiding Place

Now we need to cut a space for the object to sit in, I traced and cut an SD card sized hole in the disk

Step 4: Put It Back Together

Now you need to put the thing back together. You don't need the soft things but you need the disk. I simply taped the bottom and used the clip to hold it together.

Step 5: Final Thoughts.

You are done. I sugest adding a label to your disk to fool those trying to steal your data.

I don't know if you were being sarcastic but.... My brother has a 512 MB SD-card.....

I was being sarcastic. You can get 16GB SDHC cards! That's like 2 full DVDs in the size of your thumb.

And now, just a year after this comment, you can get 32GB *Micro* SDHC cards.  That's more than 4 full DVDs in the size of your thumb NAIL!  It's amazing how fast technology is advancing these days!

And only little more than a year that comment also, you can now get 128 GB SD cards. Is this evolution exponential or what?

It's been a while so I thought I'd chime in that you can now get SD cards of 512 GB and 128 GB mSD.

I have 2 devices that settle on the lower end. An SD car at 256 MB, and an old 8 MB flash drive.

Just figured I'd throw that out there. Also have a 2 GB flash drive that has 120 MB left of space...

you can get 1tb sd cards, and the NSA uses 3pB cards, but that is not for sale, as it would render other storage obsolete with its hugeness. (that is untel the new adobe pdf comes out, cutting the space in half. roflmao)

I wish I'd thought of a floppy disk. My instructable about hideing SD cards inside Gameboy games has more misdirection,though.

author

What happens if somebody puts it in a drive? When the drive tried to spin the disc, the SD card could jam up inside and get the disk stuck. Maybe you should cut around the hub so it can spin independently.

Then again, anyone who uses floppy disks is all too familiar with jammed disks caused by the shutter getting bent.

Actually, what would be interesting is if you could find a way to squeeze the card ( or it's circuity) in along with the floppy and not damage either. Then store useless data on the floppy to deter suspicion. Or, you could design a mechanism to emulate the magnetic material of the floppy and attach some kind of mechanical mechanism that will trigger it to read from a storage device (sd card, rom, eeprom) or cause it to send garbage and make the computer think the floppy needs to be formatted.

Who has floppy disks anymore?  Figure out how to do this with a DVD and you'll really have an amazing trick!

Is it actually easy to get the cover off the floppy disk and gain your SD card again? Great Instructable.

author
munchman made it! (author)munchman2009-07-02

Yep, just pull off the plastic/metal clip and unfold the two halves of the disk.

I've published another instructable that should make old WordPerfect 5.1 for Windows users interested:

Great Instructable, by the way

i noticed u lost the spring, people mite catch on if the cover aint working having said that, we use to use them without the metal bit on often! all u need now, is something that destroys/wipes the sd card when inserted into a floppy drive!

author
munchman made it! (author)munchman2008-02-27

Yeah! Shame flash drives aren't magnetic. Magnets would be fun! But I suppse you could somehow implement a card reader? Or make the floppy nto a card reader and use a floppy drive to read the SD card!

author
gmjhowe made it! (author)gmjhowe2008-02-27

i was thinking more along the lines of some kind of pcb melting acid stored in a capsule that is triggered when the sleeve is slid back. turning a floppy drive onto an sd card ready sounds like a good idea. get on it!

In my naive youth, before USB flash drives were ubiquitous, CD burners were £20 and I knew how to wire a network, I wanted a cable with a fake floppy disk on each end (like a car stereo "tape converter" but floppy->floppy rather than 3.5mm->tape) so you could plug one end into each computer, set one loading from the disk and the other saving to the disk. Now I realise what a terrible idea that is, and why no-one had done it before. My point is I'd still like to see a cable with a fake floppy on one end and a USB flash drive/SD/CF/hard disk/network/whatever else reader on the other end, so you can easily put files on legacy machines if you don't have another machine with a floppy drive. Shame it's borderline impossible and well beyond borderline crazy.

Yeah all you'd really need is a little coil in the floppy above where the read/write head would go in the drive, attack the wires of the coil to another one of those disks in the other pc - or something lol. Or you could just use a serial to serial connection if it has no USB/CD :P

PKM made it! (author)PKM2009-06-15

The hardware wouldn't be the problem, it's the fact that the information on the disk isn't just a string of bytes but has a file system. You could possibly write a program to get around this and just stream bytes to/from the disk drive, but then you are just implementing a very simple network with obtuse hardware. It's not the weirdest hack I've seen, one of the groups in my degree had to build a device that let you stream files off a computer by putting a grid of photocells over the monitor and flashing squares black and white to push information out :)

in understand what u mean, my advice for legacy machines is hdds, old machines use ide connections,but it is still standrad to find this connection on most new computers, if u arnt scared of poking around, this would be ur best bet
