The proper way is to get yourself a shredder that also handles cds - look online for cd shredders. This is the right option if you end up doing this routinely. I don't do this very often - For small scale destruction I favour a pair of tin snips - they have enough force to cut through a cd, yet are blunt enough to cause small cracks along the sheer line. ...

You could try pressing the card together (in case it came a little loose?) and maybe cleaning the contacts with a little bit of isopropanol on a swab. But I really wouldn't expect any results, and at best you might manage to read some of the data off before it dies again. I would not recommend opening it up under any circumstances - that will not help ...

This website explains 10 creative ways of doing this: Wraps the discs with food wrap then fold it. Shred the discs. There are several CD shredder machines, that operate like common paper shredders. Cut the discs. If you don't use a shredder, a heavy pair of scissors can easily cut through a disc. The reflective foil will crack and ...

Overview The longevity of the data stored on any drive depends on the conditions where it is stored and for how long. For hard drives, there are three main factors: magnetic field breakdown, environmental conditions, and mechanical failure. Magnetic Field Breakdown Most sources state that permanent magnets lose their magnetic field strength at a rate ...

Always-on encryption allows you to secure your data by setting a password without having to wipe or separately encrypt the data. It also makes it fast and easy to "erase" the entire drive. The SSD does this by storing the encryption key in plaintext. When you set an ATA disk password (Samsung calls this Class 0 security), the SSD uses it to encrypt the ...

Ahh, the dark arts of file identification I rather like trid for this. It identifies and renames files if you choose, has a nice large database, and is totally independant of file, so you have two approaches at your disposal.

Imagine a library in 1970. You had all the shelves with the books on them and you had drawers with cards that could tell you where the book you were looking for was located. On a hard drive, you have a table (the drawers) that's separate from the files (the books). Your operating system references this table when it needs to find data. It then goes to the ...

In general, deleted files don't go anywhere. They remain on the disk exactly as they were until they happen to get overwritten. When they are deleted, a link to it is simply removed from the file system structure.

No. The Recent Documents icon is just a link. To recover the documents you really do need to have the USB drive. Note that it's likely a teacher found the USB drive and is keeping it safe until someone reports they lost it. I'd ask around with teachers if they found your USB drive.

Is it possible if I could recover any of them? The Word "Recent Documents" is just a list of filenames (and their locations) of documents you have recently edited. It does not contain any of the documents' data. If you still have access to the machine where you last edited the documents, then it may be possible to recover them. However, it is very ...

Once. Modern magnetic media are quite efficient, and leave behind very little evidence of former bit positions. What is left behind requires electron microscopes and/or high-tech magnetometric (or whatever they're called) scanners. All such devices are horrendously expensive, and even with the best equipment and most-skilled experts, it takes a monumental ...

The answer by Journeyman Geek is good enough for almost everything. But oddly, that common phrase "Good enough for government work" does not apply - depending on which part of the government. It is technically possible to recover data from shredded/broken/etc CDs and DVDs. If you have a microscope handy, put the disc in it and you can see the pits. The disc ...

Look at the USB connector in your first picture. To the left of it, there are four solder joints fixing it to the printed circuit board. The topmost one (in the image) appears to be cracked, and to have been soldered poorly in the first place. This is a common problem with USB memory sticks. Usually the USB connector is mounted without any kind of strain ...

I think the value function can be useful for you = VALUE(< CELL >) PD: In spanish we use the function VALOR: = VALOR(< CELL >) i think it should be the same on english

Photorec is designed specifically for this. It looks at file headers for various well known files and recovers photos - it does however mangle up filenames so you may need to rebuild these from exif data. CGsecurity also has an application called testdisk for whole drive recovery, which the OP ended up using. This is useful where you know the disk is in ...

It is a beautiful utterly elegant hack used to save on wear on the disk. Scrambling/randomising data on MLC drives also improves reliabilty on smaller process sizes - see this paper and these two referenced patents (here and here, and encrypted data is essentially random (thanks to alex.forencich for digging that up in the comments). In a sense AES ...

Save time, I just use a 5lb hammer. Note: wear safety goggles. Or buy one of these

Why would you format if you are trying to recover files? Formatting wipes the disk; that’s the whole point. It doesn’t matter whether you do a quick or full format, the purpose of formatting is to erase the drive and mark it as empty. A quick format may only wipe the FAT instead of the clusters containing the actual files, but any recovery attempt will be ...

I broke a capacitor off a (very expensive) video card once. I am not the best with a soldering iron, so I didn't want to risk ruining my card. I brought it to a TV repair shop in my area and the technician was able to solder it back on. It cost me $30, I think. That might work for you.

A link to photorec was posted, but it only finds known file types. My files were of all random types. The nice thing, is photorec comes with testdisk. Using testdisk, I worked on the image I made with dd : # dd if=/dev/sdg of=~/tmp/sd.bin # sudo apt-get install testdisk #if on ubuntu/debian # testdisk ~/tmp/sd.bin (Select the partition) (Advanced) (Boot) (...

If the tape is DECtape, you will definitely need to find a TU-56 drive to read it. TU-56 units are going to be pretty hard to come by, and would likely require some repair (replacement of old capacitors, decaying wiring, burned out indicators). As far as hosts go, you are way more likely to find a working vax than a working pdp-8, but you will need the right ...

I typically put my old CDROMs in a plastic bag and use oven mits to bend them. This protects my hands from shards and protects the surroundings from flying projectile shards.

On newer drives, even the high-power magnets I used to use don't work anymore to erase the disk. If you have a spike, or similar object (hard metal that is pointed, think of a nail that is much bigger) and drive it through the center of the chassis with a hammer. That will bend the platers and damage the heads making it extremely difficult to recover. A ...

Dectapes are easily differentiable from standard open-reel tapes as they were 1-inch wide and the reels were maybe 4-5 inches in diameter, and the flanges were maybe a half-inch deep. Dectape was one of the most robust media of its day, if not THE most robust. It had redundant timing and data tracks and could be read or written in either direction. The ...

You're correct; physical destruction is the only good way to do this (you'd need a magnet so strong that it's not feasible to get one for most people unless you're on staff at the Large Hadron Collider). Professional disposal operations generally do this with an industrial metal shredder. For you, bending the platters with a hammer, sandpapering them, and ...

The data on the HD will last much more than two years, so there is a very good chance you can recover it. The only problem might be that new hardware could be incompatible with old hardware, but two years isn't long at all.

Try this. Open a command prompt. Execute the mountvol command which will tell you all the volumes on your system and give you the GUID of them. \\?\Volume{eb38d03b-29ed-11e2-be65-806e6f6e6963}\ *** NO MOUNT POINTS *** \\?\Volume{eb38d03c-29ed-11e2-be65-806e6f6e6963}\ C:\ \\?\Volume{41ae7a1c-9849-11e2-be7a-0026b9dc157c}\ F:\ I bet the one ...

To me that looks fixable with a fine point iron and multicore solder. You may find it easiest to bridge the gap with wire rather than attempting to put it back into its original shape. Alternatively, if you don't have a soldering iron, you may just about be able to strap it up with tape to make contact - I've done this on older hardware but never on USB. ...

This assumes you're going for an archive rather than regular backup or live data. Go for a set of SATA hard drives (1 or 2 TB), plus a few extras. Copy your data onto the disks. Use QuickPar (or an archiver which support parity volumes) to create additional parity files. Distribute parity files among your hard disks. The parity info will allow you to ...

In case of mechanical failures. Pray, it well help you and calm you down. :-) Introduction If you have a mechanical failure (e.g. random crashes, just stops working one day, weird "screeching"/"beeping" type noises), EVERY time you plug it in and turn on, you could be making it much worse. If it is very important data, I would recommend taking it to a lab ...
