How to Recover Deleted Pictures or Files – Data Recovery Tools and Techniques

Trashed hard driveHelp, I lost My Pictures!

If you lost or accidentally deleted your pictures and files, there are still great chances to recover them. As a computer geek, (I do this as a profession), I had to recover file many times. In the vast majority of time the files are recoverable, and in about 30 percent of the cases the retrieval is instant.

The key to a successful retrieval of your pictures and files is to act as soon as you discovered you lost the files, be it because an accidental deletion, or computer problems. I will explain this later in the document.

This tutorial is created for Windows computers, and it assumes you have a minimum knowledge of operating in a Windows Operating System. If you don’t know how to operate in a Windows environment, your best bet is to go to a local computer repair shop.

How To Recover Deleted Pictures or Files?

The Computer IS Fine, But My Files Are Gone

If the computer is fine and it doesn’t behave erratically, most likely you accidentally deleted your files. The first step in this case is to check in the Recycle Bin, but I bet you already did this. If you didn’t do it now. Look for pictures or maybe just a folder, If you accidentally deleted the whole folder, you won’t see the files or the pictures in the Recycle Bin, you will have to look for the folder that contains the files. This is particularly difficult if your Recycle Bin hasn’t been emptied in a while, and you have to search through thousands of files.

How to Recover Deleted Files from Recycle Bin – Advanced Tutorial

Sorting the Items In the Recycling Bin

If your Recycle Bin is empty, or you have few items, you can skip this.
To make it easier right click in the “Recycle Bin” folder and choose sort by “Date deleted”.
If the deletion was made long time ago this doesn’t make sense, and you would probably need to sort by type. Sort by type is not available by default on the Recycle bin, so you have to activate it. Right click in the Recycle Bin folder, select “Sort By”, and the choose “More”. Scroll down on the list and check the box for “Type”. Now the “Sort by type” is available from the contextual menu. When you sort by type all the folders are displayed grouped so it’s easier to find your pictures folder if it’s in the recycle bin.

Recover Deleted Pictures or Files Using “Previous Versions”
Recovering with Windows 7 Previous Versions
If your operating system is not Windows 7, you can skip this paragraph, this feature is only available on Windows 7.
If your files are located on the System drive, usually the C: drive, “Previous Version” is enabled by default. “Previous Version” it’s a feature that allows the system to store on a hidden portion of the drive, files and system settings. The files are automatically copied on the hidden folder, and stored for a limited numbers of days. When a file is modified, or deleted, the old version is stored automatically. Let’s say you deleted some pictures in the “Pictures” folder. Go to “My Computer” => C: => Users => USERNAME . Search for the “My Pictures” folder and right click on the folder. From the contextual menu select “Restore Previous Versions”. A list with snapshots of the folder will be presented. Select a previous version that you think contains the deleted files. If you accidentally deleted the files today at 11:00 AM, any snapshot previous to this date and time would contain the deleted files. Neat huh? The trick here is to act as soon as you deleted the files. The longer you wait the bigger the chances to get the good snapshot deleted are. The snapshots are deleted on a regular basis by the system, so if you wait too long, the files will be deleted.

This is probably one of the easiest, and most effective image recovery software.

Data Recovery Tools

Recovering Deleted Files with Data Recovery Tools

If the two methods described above didn’t work for you, that means the data has been erased from the disk. The good news is that operating systems do not really delete the files when you delete them, the OS only deletes the record from the index, so from the OS’s perspective the file doesn’t exist anymore. This is where the data recovery software comes in handy. The data recovery software scans the drive for possible files that are deleted from the index, and reassembles them for you.

As with any other recovery method the key is to act as soon as possible. The more you use your drive after the deletion, the less chances you have for a full recovery. This happens because Windows treats the portion occupied by your lost files as empty, and will start to write new data over your deleted files. The more you use the drive the more deleted data is overwritten.

The data recovery software is usually an intuitive program that can be installed on the computer, or can generate a bootable media. The purpose of the bootable media is to avoid the use of the hard drive, to maximize the chances of a full recovery, or sometimes provide an environment for un-bootable systems.
The process of recovering data with tools is very easy, and it is somewhat similar for all software, but not all data recovery programs are the same. The scanning algorithm, the reading approach are things that can make or break a recovery utility.

A few general rules for all recovery software:
To avoid further data corruption, mount the corrupted drive on another intact system. You can do this in a couple of ways:
Install the software on a separate system and attach the drive with a USB enclosure or adapter.
Create the recovery media on another computer and boot the computer with the bad drive from the bootable recovery media
Only start doing the job when you have enough time to dedicate. If you start and stop, and then start again you risk to lose more data.

How Can I Recover My Pictures After Formatting the SD Card

Pictures Recovery after Deletion or Formatting with Recovery Software

If you accidentally deleted your photos on the SD card there is no Recycle Bin for the SD card, so there is no easy way to recover them. Also it happens quite often to format your SD card and to realize that you didn’t save the pictures yet. What do we do in cases like this?
Fortunately, there is software that makes the recovery for cases like this a breeze. One of the easiest to use programs is “Sandisk RescuePro Recovery Software”.

Sandisk RescuePro Recovery Software, V3.3 Disk

It works on and card not just on Sandisk cards. It is really easy to use, and in most of the cases it is able to recover your pictures. One thing about this is that you need to wait the code for the software for a few days, but is worth. The software is actually an annual subscription, but it is very affordable.

Remember, if you deleted the pics on your card, or formatted the card, you need to stop using it immediately to insure a good recovery rate.

Recover Files from A Defective Computer

How To Recover Pictures and Files from A Defective Computer

Your computer might be defective and it won’t start. What to do in this case? First you need to assess the state of the computer and why the computer won’t start. Depending on this, you might be able to recover your files or not. In the next paragraphs I will give you tips to know what is wrong with your computer, and what to for each case.

  • If your computer boots and you can get on your Windows account, then probably the files were accidentally deleted.
  • If your computer passes the initial boot sequence but stops when loading Windows, it is the operating system that is corrupted. A re-installation could fix it, or a boot rescue CD could also fix the OS. Sometimes this could be due to bad computer RAM memory.
  • If your computer doesn’t pass the initial black screen booting sequence, something more serious could have happened, such as a defective hdd, or some other hardware problem.
  • If the computer doesn’t do anything, it is also a hardware problem. You can tackle this with a local computer shop, or proceed to moving your drive on another computer.
  • If the computer starts but it doesn’t recognizes your hard-drive, then you cannot rescue your files anymore. Actually there are data recovery services, that will disassemble your drive, and will read the data on the platters with special equipment. These are special services and are very expensive. Most of us prefer to lose the family pictures than to pay for these services.

What To Do If The Computer Won’t Boot

My Computer Won’t Boot, I Need My Pictures And Files

There are many reasons why your computer won’t boot. If you think your computer is not worth investing too much work to revive it, then the easiest way to recover your files is to take out the old hard-drive, mount it on a USB enclosure, and read it through USB on a good computer. You will be able to read your old files without any problems. This method assumes your hard-drive is not defective.For the case that Windows won’t boot because of a file-system corruption, or other Windows corruption problems, there is the Recovery Boot Disk that will allow you to boot your computer and fix a wide range of problems.

If the hard disk is the one that caused your computer to not boot, you still have good chances to recover your files, but in many cases you need a data recovery software like Data Rescue PC 3, to scan for files on the corrupted disk.

If the computer warns you before booting that there is a problem with the disk drive, you need to stop immediately using the drive if you want to maximize your chances of recovering the data. If your drive is making clicking noises, you also need to stop using it. Sometimes a hard-disk will have just enough life for a last run, so after recovery it will die.
The next step is to acquire data recovery software and install it on a good computer, and buy a USB enclosure and use it to mount the drive from the defective computer. Now connect the hard-drive to recover on the good computer and start the recovery.

Data Loss Prevention

What can I do to prevent data corruption or data loss?

  • Enable in BIOS and on the hard-drive S.M.A.R.T. This is a software utility embedded on the hard-drive that will detect when too many error corrections are occurring. Whenever this happens it means that you drive is near an imminent failure and you should backup/replace it.
  • If a message of a hard drive error appears, stop using your computer until you change the drive. You can use the computer to make a backup of your data onto another drive.
  • Check old backup tapes and copy them onto new tapes, using a temporary restore. This should happen each 10 years or more.
  • Check the data stored on CD’s and DVD’s, and recopy that media regularly. Not all CD and DVD media are equal. The factory-recorded media is the longest lasting. The media burned at home or on a computer CD-ROM unit can last between 1 to 10 years or more. So it is wise to rerecord it after a few years if you bought good quality media, or after one year if it’s on cheap media.
  • Buy an antivirus and keep it up to date.

Free Protection against Computer Viruses and Other Malware

Today’s computers are under a constant assault of viruses and other malware. We all need to have up to date Antimalware software to protect our computer. Buying antivirus software and subscription could be expensive because you need to update your subscription yearly. However there are free options for your computer’s security.

What is Malware?

Computer Malware

Malware is a general term for any software designed with the intention to affect negatively a computer or to steal private information.
Malware includes computer viruses, worms, trojan horses, rootkits, spyware, adware, crimeware and other malicious software.

There is a misconception that only Windows operating systems are affected by Malware. However, this isn’t true. Mac’s and Linux machines are affected as well. There are not as many viruses written for Mac and Linux machines, but this is mainly because of their popularity as Operating Systems. Windows OS is the most popular therefore many Malware programmers exists.

Today a computer without an antivirus is extremely vulnerable. Especially if the computer is connected to Internet or and exchanges files with other computers, which is the case of most of the computers today. More than that, nowadays an antivirus is not enough for avid Internet users. There are so many types of threats that an antivirus alone will not protect you entirely. All computers should have an up to date Antivirus and Antispyware as a minimum. Sometimes, websites that seem inoffensive can infect your computer with spyware, Trojans or even computer viruses.

Some websites will create deceiving pop-ups to mislead you in believing that your computer is infected. An action is requested on the next step asking you if you want to scan your computer. Many times you don’t have the choice to refuse this action as the pop-up special crafted and you cannot close it. The best thing to do in this situation is to save all of your work and logoff or reboot your computer. Advanced users can alternatively kill the task from the task manager.

Free Antimalware

There are a few good choices for people who don’t want to pay for their computer security. There are free antivirus, free antispyware, free personal firewalls, and free anti add-ware. The vast majority of them are only free for personal use. In other words, if your computer is a company computer you should buy a license.
Don’t forget that you need to have at least an antispyware, an antivirus, and a firewall to be protected, or software that combines all of them.

Firewall

Firewall

A firewall is a must for any laptop, since connecting your laptop in other networks puts a serious threat on the security of your computer. Depending on how your home firewall is configured, if you own one, you might need a firewall on all of your home computers.

A basic firewall is included with all modern operating systems so you don’t need to buy one. However, if you need a more advanced personal firewall that gives you a very granular control of all your network and Internet activity, in and out, you should consider the free Sygate Personal Firewall, or Online Armor Free, or Comodo firewall which is part of the Comodo Internet Security suite, or Sunbelt Personal Firewall.

Antispyware

Spyware is one of the most common Malware today. Spyware can range from almost inoffensive pieces of code to software that will damage your computer and make you lose data or steal private information from your computer. A computer without an antispyware protection will be, sooner or later, affected by spyware.
There are a few free Anti-spyware products on the market. I will first mention the free for anyone “Spybot-S&D!”. It is a good antispyware with a long history on the Market. You need some computer knowledge to configure it for best results. If you need a scan only free Anti-Spyware it’s one of the best choices.
Ad-aware, the known anti add-ware has evolved to an antispyware program. There is a free limited version.
Windows Defender is Microsoft’s antispyware solution. Windows Defender is now part of the operating system with Windows Vista and Windows 7. There are Free, (for Personal Use), Security Suites that include antispyware as part of the bundle. See the Security Suites for more antispyware.

Antivirus

Antivirus has always been a must for any computer that exchanges data with other computers in any way. There are viruses that can even render your computer useless. For instance the virus CIH will corrupt your computer BIOS. The BIOS chip is essential for starting your computer. Other viruses will trash all your hard drive data.

Free antivirus programs exist on the market. ClamAv is a free, open source, antivirus for both personal and commercial use. Other free for personal use Antivirus include Avira Antivir, Kaspersky Anti-Virus free edition, Norton Security Scan and eTrust EZ Antivirus as a one year trial. There are also free online scanners, many antivirus manufacturers provide an online scanner for free.

Security Suites

Security suites are sets of Anti-Malware programs designed to protect against more than one threat. They can contain an Anti-Virus, an Anti-Spyware, Anti-Phishing, a firewall, an Anti-SPAM, as well as other protections against Malware. They are the choice of most of us since they are easy to administrate and don’t require advanced computer knowledge.
Very popular Free Security Suites are AVG, Avast, Comodo Internet Security, Google Pack – a collection of software that includes an antivirus and an Anti-spyware and Microsoft’s Security Essentials.

As you see, there are a lot of free choices, so not having an up-to-date Anti-virus and Anti-spyware is free if you can’t afford to pay for one.
Share you thoughts about Internet Security and your choice of Antivirus.
