It is a dreaded occurrence for anyone using a computer to carry out a project or just go about the day to day duties like filing or finishing assignments to accidentally delete a particular file that was of extreme importance. This does happen even to the best of us and when most of us find ourselves in such a situation, not being sure what to do, they start panicking. This should however not be the case as with the proper guidelines and tools necessary; one is capable of retrieving their data and overcoming the error of accidental data deletion.
How to Recover Accidentally Deleted Data
There are various ways available for anyone who has faced accidental data deletion. These vary in technique and tools used in the recovery process. It should however be noted that whereby the free and at times some software that are paid for are unable to recover your data then you will have to seek the services of data recovery companies which at times tend to be expensive.
There are certain programs that may be used. These may be programs like the TestDisk that is actually a freeware that has proven to be effective and is definitely worth trying out before settling for the more expensive options. The Test disk program usually comes bundled together with PhotoRec, which is actually a program that is used when recovering photos from mainly the SD cards whereas the TestDisk is actually a program is for mainly recovering files that are on the hard disks.
After you have downloaded the program file, you then extract it and then proceed to run the test disk application that is situated within the directory. You will then see that a command prompt, then pops up and that is actually how the program normally runs. It should be noted that the program is actually really easy to use in the event of accidental data deletion.
The program will then ask if you may want to create a log file, append an existing one or even not use one completely. It should be noted that it is advisable to simply leave it to create and proceed to press enter. You will then be asked to state the particular disk that you want to be scanned.
Accidental Data Deletion Retrieval Do’s and Don’ts
Before engaging in the process of data retrieval due to accidental data deletion, it is extremely critical that certain things and procedures should not be overlooked. It is very important for one to always first of all check their computer recycle bin just to make sure that your files are not still available in there. If this is so, then one just needs to right click on them so as to restore them. It is also important to make sure that all other programs are closed out including even the programs running on the taskbar. Finally, one should not create any new files, move any data or even copy any data.
It has nowadays become a common trend for everyone to opt for the use of smart phones. Smart phones have become very popular with the phones being turned into the very center of our lives. From taking photos with loved ones and friends, to taking selfies, to storing our favorite music collections and even movies, to storing our important data and even for our downloads. The list just keeps going and this is one key indication that smart phones have become a necessary part of our day to day lives. However, these are just simply machines and from time to time, they tend to be prone to either physical or logical damage. This often leads to the loss of the very important that we always have stored in them. This leads to the necessity for smart phone data recovery processes and procedures.
Smart Phone Data Recovery Processes
In such a case as when one has lost the data stored in their smart phones, it is important to first of all look into all the viable options available to them before making a decision on which one to proceed with. This information may easily be accessed through the internet as most service providers provide detailed guidelines on what their users may do in case of such an occurrence. If one is extremely sure on how to go about the data recovery process mainly meant for smart phone data recovery, then he or she may download the data recovery software available on the internet and proceed to follow the steps and guidelines given to the data recovery process.
This should however be noted as an option that one should undertake strictly if and when they are completely sure about they are actually engaging in. If one is uncertain on what to do In this case scenario, then it is highly recommended that one seeks the services of a professional data recovery firm, or he or she may opt to contact or return the smart phone to the actual phone company for assistance or one may actually just go ahead and contact their wireless provider and ask for the assistance needed. This is actually better than trying to retrieve the data on your own just to end up messing things up more. The data recovery companies’ services are preferable since they are not only trustworthy, but are also fast and offer a money back guarantee in the event that they are unable to retrieve the data for smart phone data recovery.
Smart Phone Data Recovery Key points
In the event that your phone lacks a USB Mass Storage mode, it is usually possible to add it through using a modified kernel or even a kernel extension which either may or may not require a firmware Reflashing. It is important to note that while these procedures are harmless, android phones are designed to be open and also extendible. This needs a fair level of technological knowledge
The difficulty of recovering lost data depends primarily on the extent of the data loss that occurred. When a hard drive crashes, the solutions to recovering the lost data can range from simply recovering files from backup, to using an emergency Boot Disk to needing the help of a data recovery service.
If the user prepared a backup of files on an external hard drive prior to the event of the crash, this is the easiest way that the data can be recovered in case the computer’s hardware crashes. Computer professionals always recommend the importance of backing up user files at regularly scheduled times.
Files can also be recovered through an emergency Boot Disk. When the hard drive is not recognized by the computer, the user can check if it is detected by the BIOS, the shell instructions that run in the background when a PC starts up. If the drive is detected, files may be restored through an emergency Boot Disk. Change the directory of the hard drive and check whether the Master Boot Record is damaged. Master Boot Records can be repaired on a PC with a DOS command prompt by typing fdisk/mbr. This will ensure the safety of the files and will allow the user to access and back them up once the Windows reloads.
Another way of recovering lost data if the hard drive crashes is through the data partition. This can be done by booting the computer from the computer’s startup disk and recovering the files from the data partition. However, data recovery is more difficult when there is no partition visible.
The user can also download and install freeware programs or purchase programs online or in stores that can recover data. As long as the files are not overwritten, there is a good probability that they can still be recovered. Different recovery programs are available in the Internet and can assist in the restoration of files from the hardware.
If there is no way the data can be recovered by using these simple methods, a professional data loss technician can assist in more complex situations. This is important especially if the hardware has physical damages. A data recovery expert is more knowledgeable regarding the proper way of recovering data, ensuring that the files are safe and can still be recovered.
One of the common causes of random computer crashes is that of an overheating computer. This overheating of the computer is mainly caused by the blockage of airflow through the computer, this is also followed by a failing or completely failed fan. Everyone probably knows that there are fans set up in their computers whose sole purpose is to move the cooler air throughout so as to cool down the components that are in the computer. The PC processor, hard disk drive and some more components therein all make the heat, and should this heat not be in a way dispersed, then the components themselves tend to become too hot, hence start functioning improperly, and then end up causing a crash.
This is Particular when it comes to the laptops, especially; it is extremely easy for one to accidentally block the air vents which allow the air to flow properly within and through the device. It is actually recommended to never put the laptop on one lap: instead one may opt to use a table or if possible a laptop desk sort device which ensures that there is proper airflow.
However, the desktop computers are usually more vulnerable to dust and pet hair, which are capable of clogging the air vents, thus preventing the flow and circulation of air. It is usually advisable for one to unplug their computers and check the inside. Then one should carefully clean it out if there is the presence of large quantities of dust and dirt inside it. This is so as to avoid the computer crashing thereby necessitating the recovering of lost data.
The Process Of Recovering Lost Data
There may be situations whereby one had been smart enough to back up their data, in such scenarios, then if the files had been backed up to a compact disk or any other form of electronic data storage, then the process of recovering the lost data is made easier. It is then recommended that the particular file that was lost be restored from the backup source in hand, if the lost or damaged files cannot be located.
There may also be scenarios whereby the lost data may have been accidentally deleted, but may still be accessible in the recycle bin. In such scenarios, then the file is simply restored from the recycle bin.
Options for Recovering Lost Data
In the process of trying to locate and recover lost data, one may be faced with various challenges such as developing complications during the attempt of recovering lost data. One should also remember that whenever a file is deleted, it may have been marked as deleted, but in the real sense it has not been removed from the hard drive. This makes it possible for one to still go ahead and recover the particular file. This may be done by one downloading a free data recovery program and should there be further complications one may consult a data recovery company.
You were working smoothly on your computer and all of a sudden your hard drive stops working. It might start making weird sounds or be completely mute depending upon the type of failure it is confronting. U are no longer able to view the folders from your hard drive and no data is accessible.
Try these methods to recover data from your dead hard Drive:
- Basic Inspection
Always turn off your PC and check for basic faults before drawing any conclusion about the hard drive. Sometimes its just the cables that are not plugged properly or have gotten loose. Make sure the power and data cables are snugly attached at the ends. Also check for any physical damages on the body of the hard drive.
- Connect the drive to another PC
The easiest way to connect the drive to another PC is by using a USB IDE/SATA ADAPTER. If you do not have one available you can manually insert the hard disk into another PC as secondary device. Make sure the computer detects the hard drive in BIOS before it starts up or you wont be able to access the drive. There is a huge possibility that the drive may start working on the other PC and fault is in your motherboard.
- Use Linux to Recover Data
Sometimes you can get confused between a damaged file system and a hard drive failure. A damaged file system can also cause the Windows to not be able to see the drive. Running a file system repair can also get the problem solved.
- Run Data Recovery Software
when you get sure the fault is in the hard drive itself you should download any of the different softwares that are available on the internet for data recovery. Many of these softwares are free of cost and are efficient to get the job done for you. Rocuva, PC Inspector File Recovery, Hiren’s BootCD and GetDataBack are good softwares for data recovery. Mac users can use MiniTool Mac Data Recovery and Disk Drill to get the job done.
- Freeze the Hard Drive
Sometimes the shaft of the drive expands due to over heating. This creates a blockage between the shaft and the bearings which seizes the hard drive from working. Keeping the hard drive enclosed in a plastic bag in the freezer for some time allows the material to shrink and get back to its original state, hence, clearing space for the shaft and bearings to turn.
The one best way for one to recover from an unexpected data loss is simply to be properly prepared. With any one of the following tools being on hand, you will always be ready to not only save but also secure your data from imminent loss. These data recovery tools are a must have. Whereas the best defense against data loss is usually the redundant and an actual real-time backup, we do understand that at times data loss comes unexpectedly. Whether it be that your vacation photos didn’t make it safely from your digital camera to your computer or a clumsy roommate deleted the very paper you have been tirelessly working on all week, having the right data recovery tools handy is very crucial to retrieving your data before it is completely lost.
List Of Data Recovery Tools
One of these data recovery tools is TestDisk. This is actually a powerful open-source tool used for recovering your lost data. Not only can it perform the basic file recovery such as undulating the accidentally deleted files from the FAT, the NTFS, and the ext2 file systems, it also comes with a host of quite an amount of additional functionality.
Other Data Recovery Tools
Another outstanding data recovery tool is Recuva. This is actually a user-friendly Windows-based tool. Whenever you do run Recuva, you are capable of resurrecting missing files by using either the file-recovery wizard or you can use the application’s own manual mode. This file-recovery wizard is useful when you are certain that your data is gone, but not quite sure where it is located or how to retrieve it. This wizard allows you to narrow your search type to either pictures, or music, or documents, or video, or all files, and you then can set the search location to your whole computer, or removable media only, or My Documents, the Recycle Bin, or even a specified location. Should you not require the wizard, you can go right into manual mode and get down to work looking where you know the file should be.
Recuva usually uses a green/yellow/red light system to show how probable the recovery of your files is, and if available, it provides a preview image files available for the recovery. It also includes a tool for securely wiping files you find. It is handy when attempting a file recovery just to ensure that the files are actually truly gone.
From time to time, many of us find ourselves in need of the partition recovery now and then. You must have had the experience whereby the system cannot find the partitions. Therefore, if you actually want to gain access to the files on the partitions, then you will have to definitely recover the lost data first.
As we all know, one physical disk is capable of being divided into several partitions (in relation to the drive letters such as C: or D :), they may also be called “volumes”.
Once a hard disk has been divided into the several partitions, the directories and the files of different categories may actually be stored in different partitions. More partitions therefore provide more control, but too many may then become cumbersome. There should be Careful consideration of the number of the partition that is actually necessary, as this helps avoid the causes of corrupted partition.
Main Reasons for Partitioning
Given the varying needs of computer users, the need for portioning may vary depending on the individual and the activity being undertaken with the computer. It should however that even though portioning has its advantages, corrupted partition may lead to inconvenience. Generally in summary, we can then come to a conclusion on the purposes of partitioning as followings; so as to Keep and maintain the Operating System files, the frequently used programs and the user data near one another. Also, so as to have an area for the Operating System’s virtual memory swapping and or paging.
Having the cache and the log files, separates from other files. From the use of the multi booting setups, which allow the users to have more than one, for instance, one can install the Mac OS X, the Microsoft Windows or others on the different partitions on the same hard disk. For the purpose of protecting or isolating files, so as to make it easier to recover data from the corrupted partition, the other file systems will not be affected and the drive’s data may still be salvaged if one of the partitions is corrupted. To raise the overall computer performance on the systems with smaller partitions is more efficient.
How to Recover Corrupted Partition
In the scenario that you cannot see the part you need in the Windows Disk Management, it could be lost and the data on it could also be lost along with the partition table. In reality, the partition is not actually lost, even if the partition table is destroyed by a virus or is deleted accidentally. If the partition table has been destroyed by a virus or other defects, then the free partition recovery software can help in partition recovery. Data backup is recommended in case of any accident. Recovery partition software for the hard disk is actually designed to recover the deleted or corrupted partitions on a hard drive. They run under Windows 2000, XP, Windows 2003, Vista, 2008 and Windows 7.
Without a doubt, the face of technology is always changing. This has never been more prevalent than in the world of digital forensics. It can often be extremely difficult for science to keep up with the advancements in technology, and this is something that is frequently seen in the world of forensics as various organizations find themselves playing catch up with an industry that is constantly evolving. As a direct result, it is not at all uncommon to dedicate an entire method of study to digital technology in order to make an attempt at remaining current with the technology that is in use.
Most people obviously think about uses in law enforcement when they hear the word forensics. This is true and in many cases, that is exactly the area that mobile forensics is most effective in. Law enforcement agencies of all types frequently use this type of study to better understand where someone was when a call was made or received, or to retrieve information from a particular device in order to aid in an investigation. In many cases, people have been convicted because of information that was found on mobile devices that put them at the scene of a crime or revealed other incriminating evidence. By the same token, many crimes have been solved because of information found on the devices that were owned and operated by the victims of a crime, especially when it comes to those victims who can no longer speak up for themselves. However, law enforcement is not the only area that takes advantage of mobile forensics. Just as the study of the subject can be used in law enforcement, it is equally as effective in both corporate and private investigations, as well as military applications.
Of course, as is the case with virtually any type of science, there are challenges that investigators must deal with and overcome on a daily basis. Remember, mobile forensics is still a very new form of science and the challenges that are present within it are often unique. For example, is still difficult to pinpoint a location when a mobile phone sends or receives a call. This is especially true in rural areas where the signal can ping off of several towers before finally finding one that allows the call to go through. As a result, there are times when the signal might ping off of a tower that is actually far away from where the call was actually made. Other challenges include devices that are vastly different, making it difficult to have any type of standardized practices when it comes to investigation. If these challenges do not make the entire process difficult enough, consider the ever-changing devices that are constantly being produced. As soon as a new device becomes available, the one that was new only a few short weeks ago is now obsolete. This constantly changing technology makes it exceptionally difficult for investigators to develop practices that work for any length of time. As a result, it forces them to continuously readjust their investigative methods in order to come up with viable solutions.
Mobile forensics is definitely here to stay. In fact, there is every indication that it will only become more important as this type of technology continues to become something that more and more people are unable to do without. Only a few short years ago, there were actually relatively few people that had a cell phone with them at all times, but today everyone seems to have a smartphone and a few other devices to boot. That makes it even more important to find effective ways to investigate crimes by utilizing the information that can be obtained from these types of devices.
