When Computer Systems Fail, Professional Data Recovery Can Set Your Mind at Rest
by: Olivia Wilson
Computer systems are prone to data loss with relative regularity, often precisely because they are always becoming faster and more complex. Data loss can take the form of crashes, corrupted hard disks and server failures.
A professional service will swiftly send a courier to collect the failed hard disk. Back at the laboratory, technicians will mount a close inspection of the hard drive in order to provide the client with an estimate of the severity of the problem, the length of time that it will take to fix and the cost of data recovery.
A timescale for data recovery will be agreed with the client before the hard disk is repaired and data restructures restored, the raw data is extracted and the file listings are analysed. Data files are usually returned on new media, such as DVDs or an external hard drive.
The length of time that it can take to recover data from a crashed system depends upon the nature of the crash. The failure can be due to something relatively simple, such as a crash of the computer’s operating system or simple human error. However, there can be more complex reasons for a crash, such as attacks by hackers or infection by computer viruses or malware. Most seriously of all, hard drives can become physically damaged or corrupted.
A simple problem with the operating system usually means that all the technician has to do is use their expertise to extract the data and copy it on to a new form of media, such as another hard drive or disk.
In the event of a faulty or corrupt hard drive, the technicians will have to take more drastic steps, such as making repairs to the file directory itself or by attempting to retrieve the data with the use of specialised software.
In this scenario, the technician will use a powerful microscope to examine the hard drive itself for signs of damage. A similar analysis will be carried out on the system’s electronics and electrical systems, such as its power source, servos and interfaces. The technician will carry out the same level of examination for the drive’s magnetic media, such as its read/write heads.
If the examination reveals faults or complete breakdown, the offending components will be repaired or completely replaced, allowing the disk itself to be cleaned under safe, clean lab conditions, before being upgraded and reprogrammed.
The disk will now be functional once more, whereupon the all-important data will be able to be accessed and extracted. Professional data recovery services have special proprietary programs to read any data stored on the disk’s magnetic platters.
When the data is extracted, it will be transferred to the lab’s own secure servers, before being carefully checked for errors and gaps. If any bad sectors are found, they will be repaired in consultation with the client.

7 Must Have Online Data Recovery Tools
by: Kara Hugg
The entry of a virus, malfunctioning software or a plagued operating system may cost you some important files. Below is a narrowed down list of some helpful online data recovery tools, which you can use to retrieve your important files.
TestDisk
TestDisk complements Windows, Mac and Linux data recovery needs. It is a powerful open-source tool that can ‘undelete’ suddenly lost and accidentally deleted files from FAT, NTFS and ext2 file systems. It also hosts other useful functionality. It helps recover the damaged boot sector from a backup, rebuild that boot sector and find lost partitions in dozens in format to locate the lost data and copy deleted files from partitions.
Recuva
Recuva is a Window-based tool that holds the power to resurrect missing files via its file-recovery wizard or application manual mode. When you are not quite sure of where your files are located or lost, the file-recovery wizard proves to be handy not only in retrieving missing files but also locating long forgotten files. Its manual user mode is helpful in file location.
PhotoRec
This program is a perfect complement to the TestDisk applications. It may not hold GUI capabilities but is certainly is one powerful online data recovery tool. Among its great features is that it does not mess with your computer partitions as it does not tend to rebuild your master boot record. This application is more focused on file types and operating-system agnostic. It offers help in quickly and safely copying all your suddenly lost files to another disk.
Restoration
Restoration could be the most helpful addition to your Windows-based USB toolkit. Not only does it help restore missing USB files but also your personal computer files. While it lacks the advanced functionality of most online data recovery tools, it is a very effective and generally reliable. Despite its meager 406k size, it outweighs any other data recovery tools out there when it simple applications.

It works by assigning recovery probability to searched files, depending on the severity of the damage. It allows easy file sorting by type and easy setting of filters, which will help sift through every deleted file in locating your missing files.
GetDataBack
This software helps recover lost data from your hard drive’s partition table, boot record, FAT/MFT or root directory. With the use of advanced algorithms, it ensures that all directories and subdirectories are put together and reconstructed properly. Perhaps the greatest GetDataBack feature is its capacity to enable regular users to conduct his own data recovery by guiding him in every step while giving the advanced users the leeway to interfere with the recovery operations to improve data search and retrieval results.
Stellar Phoenix Windows Data Recovery
This software will provide you with the complete solution to all your data recovery needs. It works great in retrieving all the data lost after operating system corruption, file system damage, accidental deletion and damage to the USB flash drive. With its improved recovery applications for FAT and NTFS file systems, it helps recover lost logical drives, do hard drive cloning and imaging and recover photo, music and video files from your system.
Given this chance to look over the few notable online data recovery tools, you can now pinpoint which application(s) will assure the recovery of your missing files.
