How Can Deleted Data Be Restored?

We've all been there; accidentally deleting a file which is desperately needed. It happens to everyone at some point, and is fortunately something which can likely be fixed. It could be files on a corrupted flash drive, or a hard drive which needed wiping while information needed is still on it. Whatever happens, the most important first step is not to panic; it can be fixed at home, and if not professional services do not take long and are usually quite cheap.

Before starting it's important to note that this scenario can be entirely avoided by backing up data remotely. This can be through other devices such as a spare flash drive, or cloud based services. If your data is backed up, then this scenario will never be an issue.



There are a few conditions to recovering lost files; corruption and formatting. Is a drive is corrupted, then it's likely that any data on the drive will be at least partially corrupted too. It could be bad sector corruption, such as from the drive being old or moved during write, which means that data loss will be minimal. If the drive is fully corrupted, then it would be best to contact an expert service to have the files recovered; it may require replacing parts within the drive.

Formatting is different, a drive can be formatted and the data still recovered if the format was a quick format. Quick format basically wiped each sector of the drive, meaning the space still has a remnant of the data image. The sectors here are not fully cleaned, it's just like deleting everything on the drive. Unfortunately, if the drive has been deep formatted then the data is likely lost to the home user. A deep format (otherwise known as a 2 or 3 pass format) wipes the drive, then fills each sector with data, and deletes it again for a set number of cycles. It is almost impossible to recover data like this at home without expert kit, so it would be best to refer to a data security company.

The first step to restoring deleted files is one which most people forget; check program memory for any versions of the file. Things like the recycle bin are easily overlooked, but can often have the deleted file in question. If not, then check the program which you made the file with; MS Word saves recent documents as default now, and older versions can be restored through Word itself.

If the file has been deleted from program records, the next step can be a little complicated for those unfamiliar with recovery programs. First, located where the file should be; flash drive, hard drive, cd etc. If the flash drive has a corrupted sector, then the format will show up as RAW instead of the usual FAT32 or NFTS. Before recovery, it is vital to convert the drive back to a readable format though devmgmt.msc or a third party GUI based program such as EaseUS.

Once the sector is readable, the next step shouldn't be too hard; run some recovery software. Be warned, this can take a few hours as bad sectors can cause skips in reading, but the process should be done within those hours. Another word of warning; be sure to pick a well reviewed recovery software, as some do not allow full recovery without extra payments. EaseUS is great for converting a RAW drive back to FAT without formatting, but their recovery program leaves alot to be desired. Use a Piriform product for the fastest free results, as Recuva is a great light program with full access for free.

Once recovery software has completed, set the restore location to a space away from the original directory and copy the files back over. It's as simple as that, and doing this can cause no further damage to the data or drive, so it's always worth trying before contacting the experts.

Pi Projects - Discount Home Security

Raspberry Pi is like Lego for adults; it's fun to play with, and you can make anything you can imagine. Home servers, budget computers, games consoles, smart houses, the list goes on. One of the new popular things to do with a cheap Arduino circuit is to make some discount home security. Bear in mind, this will never replace a full alarm system, but it can act as a great middle ground between a fake house alarm, and full security.

This project will require a few extras on top of the £20 Arduino circuit; a small speaker or two, motion sensors, and a voice recorder. All of this can be picked up second hand for under £30, meaning the entire project will cost under £50; a great bargain and a fun project.



The aim of this system is to act as a deterrent for any would-be-thieves who are considering attacking your house. This is best used in conjunction with an existing system, and offers no guarantees. Fortunately if history is anything to go by, thieves are opportunistic and will go for the weakest house, rather than one with some obvious defences.

Motion sensor lights are always great for home security, and can be added to with a simple Pi system. By programming the circuit to respond when the light is on, it's easy to identify any intruders by simply taking advantage of existing tech. This is where the voice recorder comes into play, though it may not be necessary. The first step is to record yourself identifying thieves. Record many of these, as if the same one is repeated it's easy to tell that the voice is fake. Three stages should be used for this; the question, the warning, and the action. On first trip of the motion sensor, a question should be asked like 'Who's there?' 'Anybody there?' or 'Who's that?'. This sounds simple, but this is often a great way of deterring B&E's.

If the motion sensor is set off a second time, a new message should be played in response. The warning can be simple like 'Get out of my garden' or 'I can see you' or more complicated 'I can see you sneaking around out there'. This is a huge red light for thieves, and most will have scattered by now.

If the motion sensor goes off more than this, one of the final messages can be played; 'I'm calling the police' or 'I'm letting the dog out, you're warned'. For Americans, this would probably be 'I'm getting the gun'. This action at the end is critical to the process, as it gives them a firm action to get out of there. Raspberry Pi can easily be set up to send a message with any stage of motion trip, texting a mobile phone or emailing authorities. It's also very easy to set sociable hours, where people may be on the property for legitimate purposes.

Another key way of defending your home from thieves is a tried and tested one; a dog barking. This is set up in exactly the same way as the external motion sensor, but is best when the speaker is indoors. Always go for a bigger dog bark rather than a smaller one; more thieves will be dissuaded by a German Shepard than a Chihuahua.

Of course, this system can be personalised in any way the user likes, that's the beauty of Raspberry Pi. Additions like indoor lights activated by the external motion sensor gives the illusion that someone is home, and the sound of multiple people indoors is more than enough to make a thief flee. Easier houses can be broken into, and it's not worth the risk when someone is home with a dog.

What Other Devices May Be At Risk Of A Cyber-attack

We are all very familiar with the threat of hacking or cybercrime within the workplace. Such everyday items like servers, desktop computers and many mobile devices like smartphones are susceptible to cyber-attacks.

But what other devices may also have cyber vulnerabilities?

The internet is all around us, and as such many devices have been developed around the internet platform. These devices have an impact on our everyday life, and as such we have come to depend on them.

For example the smartphone has more computing capability than the Space Shuttle; the smart-watch updates and downloads from the internet. Many point-of-sale equipment terminals are connected to a companys financial system, Satnav uses satellite technology and Bluetooth equipment uses wireless connectivity.

These devices are in everyday use, and are familiar technology to all of us. Many thousands of everyday devices use and require internet access to perform everyday functions; so the exposure to any kind of cyber threat is vast in our everyday lives.

In a recent report there have been many cyber vulnerabilities exposed in many of these other internet based devices which is very worrying. These devices tend not to have the level of internet security infrastructure that is expected in many of our computers, non secure emails and smartphones.


Some examples where internet based systems are being used but the level of system and data security is classed to be cyber vulnerable.

The Modern Motor car.

Motor vehicles depend heavily on technology advances for such things as Satnav, In-car entertainment and some fly-by-wire systems. Recently a major US car manufacturer recalled 1.4 million vehicles after researchers demonstrated vulnerability, where a cyber-attack could take place and the driver of the vehicle could lose control and the hackers can gain control of the vehicle. In the UK thieves have recently hacked the keyless entry systems to steal vehicles.

Smart Home Devices.

Some vulnerability have been found in internet connected thermostat systems and more worrying also found in smart door lock systems, where hackers can remotely open doors without password security. Medical Devices Vulnerabilities have been exposed in such devices including insulin pumps, x-ray systems, CT-scanners and implantable deregulators.

Smart TVs Many thousands of Smart Tvs are sold each year, and they all have internet connectivity. Therefore it is possible that these everyday items can also have cyber vulnerabilities.

Embedded Devices

Such devices like routers, webcams and Internet phones are open to criminal abuse, allowing the possibility of interception and unauthorised access.

It is imperative that these other devices are protected from cyber threats. Some of these devices may not have been identified yet as displaying cyber vulnerability, but one thing is for sure; if these devices can be hacked they will be!
