Data Recovery in Windows As Well As Mac OS

You are human and the computer is a machine. Both can fail at any time. You may delete any file accidentally. The system may fail or the hard drive may become corrupt. In all three cases, you stand to lose valuable data. You should know how to recover such lost data. The most common operating systems are Windows and Mac OS X. We shall now see the methods of data recovery in each of these operating systems.

• Windows:

– Check Recycle bin: Usually the deleted files go into the Recycle bin. You can open the recycle bin, right click on the name of the file, and choose the ‘Restore’ option. The file will come back to its original location.

– Stop accessing the drive: In case you do not find the file in the recycle bin, you should not save or delete anything from your computer. This increases your chances of recovering the file.

– Use a data recovery program: You should make use of such programs to recover your lost files. You can download these programs from the internet. However, you should not save the recovery program on the drive you wish to recover data from: save it to a drive unaffected by data loss.

– Specify your search: Point the recovery program at the disk the file was on before deletion. You can specify a file name or get a list of all recoverable files.

– Scan your computer: Performing a deep scan of your computer can help you recover the data.

– Browse for your file: Once the scan returns the results, you should browse for your file. You can restore most of the files in this manner.

• Mac OS:

– Trash: Check your trash box for the accidentally deleted file. You can restore the file from this location easily.

– Do not access the drive: Once the files are lost, you should immediately stop saving or deleting anything on your computer. You will be able to recover the lost data before you overwrite the file.

– Download a data recovery program: This is the best way to recover any lost files.
– Boot the computer: Some recovery programs require a system reboot to enable recovery of the deleted files.

– Connect a Recovery drive: When using Mac OS, you should connect a USB drive and use it as the destination for the recovered files.

– Specify scan settings: You can do a quick scan or a deep scan. A deep scan may take time. As such, you should do the quick scan first. In case you do not recover the file, you can always do the deep scan.

– Select the recoverable files: Once the scan is over, you can select the recoverable files from the screen. However, you should use the preview option to check if the recovery is complete.

– Complete the data recovery: In case you have to recover a large number of files, you should recover the essential files first. This can avoid corruption of your important files.

This is the process for recovering lost files in both Windows and Mac OS.

Online Data Storage: The Issue of Sustainability

The demand for cloud-based storage is growing rapidly, with online solutions meeting the needs of businesses and individuals alike. But how sustainable is this in the long term, and what challenges do providers need to overcome? Now is the time to consider how the digitisation of information will evolve.

Dealing with Data

The creation of data can be an intended end goal in its own right or the by-product of an action taken within the digital ecosystem. Whatever the case there is a need to store it.

In the past most data would be stored locally – held on the hard drives and memory cards of devices until required. The increase of broadband connectivity has made online data storage a practical option for everyone.

Estimating the amount of data which is generated each day is difficult, but some estimates put it at 2.5 quintillion bytes. Search giant Google alone has to handle over 3.5 billion queries each day, as well as store more than 10 billion gigabytes of data for its users.

Since almost half the world’s population has access to the internet in some shape or form, accounting for over 3.3 billion people, these figures relating to the daunting mountain of data that is piling up should be unsurprising. But that does not make them any more manageable, particularly in terms of the logistics involved with storage.

Infrastructural Accountability

The solution to the world’s data problem current lies within the massive facilities which are constantly being built to house the server hardware on which digital information can find a home.

There are data centres belonging to and used by single organisations, such as Facebook, as well as centres built to sell storage as a service to third parties. More capacity is being added on a perpetual basis to keep up with the pace at which data is being created.

The infrastructural limitations of relying on traditional storage methods, including hard drives which are housed in data centres, are well known. However there are other considerations which have to be taken into account, such as the impact of downtime and unplanned outages and the effect that can have on those that rely on remote storage methods.

Hardware faults, power problems and the bottleneck that is network connectivity all come into play. There are fears that committing so much of human knowledge to such an arguably fragile infrastructure, blighted further by eventual obsolescence, could lead to dire consequences in the future.

Seeking Durability

While digital technology may have created a conundrum with relation to data storage, it will undoubtedly be the source of the solution as well. With new storage media being researched by many companies and academic teams, the future is far from bleak.

Researchers at the University of Southampton recently unveiled a so-called ‘eternal’ storage solution which uses lasers to create a nanostructure of dots within a disc the size of a small coin, enabling up to 360 terabytes of information to be stored on a medium which is significantly more durable than a floppy disc, DVD or hard drive.

Experts claim that the disc-shaped crystals can remain thermally stable at temperatures of up to 1000 degrees Celsius, and if kept at a slightly more reasonable temperature of 190 degrees, will be able to survive for 13.8 billion years.

Understand the Importance of Data Recovery

This is the age of computers and the Internet. Everything can be found online today. People all over the world use words such as ‘hardware’, ‘software’, ‘anti-virus’, and ‘data recovery’. Around five decades ago, nobody knew these words, let alone used them.

Prior to the age of computers, physical files were stored. Now, these files are saved on computers on hard disks and other storage instruments. This is a simple way of saving data. However, the computer is a machine. It can fail at any time. During such an eventuality, there is a chance that data will be lost.

However, inaccessible data can be salvaged from corrupted or damaged computers. Data recovery is the name given to this process. There are usually three common scenarios where recovery may be required:

• System failure: operating system failure, malfunctioning of storage devices, and accidental deletion are some of the major causes of data loss. This usually happens on a computer system with a single drive or partition. The best way to recover data under such circumstances is to copy all the essential files onto another storage device. Installing a disk partitioning system, which provides an alternate disk on to which to copy the essential files, can mitigate such risks. Hence, lost data can be recovered easily.

• Drive Failure: this is a dangerous kind of data loss. Damage to the hard drive makes data recovery difficult. The hard disk stores the data. Damage to the hard disk can result in permanent loss of data. Solutions range from repairing the file system, partition table, or master boot record. The hard disk can be replaced and a one-time recovery of salvageable data conducted.

• Deletion of files: sometimes, files may be deleted accidentally. However, the system does not remove the files immediately from the drive. The deletion only removes the file references in the directory structure. A normal person may not be able to access the files. However, a trained computer engineer can conduct data recovery in such situations.

Necessity for data recovery

Today everyone uses computers to store data, from national secrets to financial data. A disaster can happen at any time. The importance of stored data is the prime reason for data recovery.

Frequent backup of data is required to prevent data loss. However, an effective recovery plan should be in operation. Every organization in the world has a disaster management system in place today.

Recovery of data is an important aspect of disaster planning. There can be huge repercussions for data loss. Hence, it is imperative for every organization to have an effective data recovery system.
