When You Need a Data Recovery Service

Have you ever accidentally deleted a file on your computer or removed your jump drive before your files could be backed up? Maybe your computer system failed or your hard drive took some physical damage. These are the most common causes of data loss. Fortunately, these files and folders can often be recovered simply by taking your drive to a data recovery service.

How Does Data Get Lost?

When you delete a file on your computer the first place that it goes is the recycle bin. Many people think that once you empty your recycle bin then the file is removed. What actually happens is that you no longer see the file but it is simply hidden. Computers’ filing systems work by removing your access to the file and relocating the file to another area for future use whenever needed. The actual data that makes up your file stays on your computer until it is overwritten by another file. Once overwriting happens then that information can no longer be retrieved. So, as long as your data hasn’t been overwritten there’s a good chance you can recover it.

How to Get Your Data Back

The process to recover lost data is very intricate and requires special tools, time, and money. In the end, though, it is all worth it to retrieve your lost information. If you’ve been working on a book for the past year and all your information is lost due to software failure no amount of money is too much to get that data back. A data recovery service will look through your hard drive and locate whatever recoverable data is there. They piece this data back together and back it up on a secondary hard drive for you to access it. While there are many data recovery software options that you can install and use to recover data if the damage to your hard drive is extensive, the best solution for getting your data back is by taking it to a reputable and experienced data recovery professional.

It is quite easy to assume that you will never be the victim of data loss but the truth is it is a very common occurrence. If you’re not paying attention for a moment you could accidentally delete something you meant to save, or if your hard drive is old its performance could begin to degrade. Whatever the reason may be for your data to become lost, data recovery services are there to help you get it back.

 

Data Recovery Procedures To Try Before Calling The Experts

It would be really a disgusting scenario if you find yourself in the middle of the work and your system crashes down. You may lose any information or data stored within seconds. It can be quite critical. You may not have enough time to call an expert at that time. So, if you know some of the data recovery procedures then it would be a great help.

Try these methods:

 There are certain procedures to recover your data on system failure or accidental deletion of data. Some of them are described here.

  • Understand the allocation table:

A fundamental knowledge on everything always gets a pass. Although the expert can help you a lot but at least the background information can stop you from panicking. When a file accidentally gets deleted the data file is stored in Windows in bits and pieces. The memory size of the clustered data is determined by the file allocation table, generally known as the FAT. This FAT captures the connectivity between the clustered data that can be reconstructed to make up for the file deleted. Utilities such as Scandisk help you to put together and restore your file.

  • Use floppy disks and drives:

If your computer crashes down on switching on, then hardly the data can be found in the Windows. In that case you must have the practice of using a CD-RW drive. For this, you will have to get the drivers to be connected to the disk operating system of the computer. Still if your drive is partitioned from the system then you can use the DOS Navigator to copy the files from one drive to another. For backing of the data and bring its successful recovery you can also use floppy drives although the capacity may be compromised. Use the emergency boot disk and slide it into the floppy drive and start rebooting. After making sure that your data is safe you can back up your data while reloading Windows.

  • File scavenger data utility:

Apart from the above simple practices there are many utilities that cover data recovery procedures. The file scavenger data recovery utility provides a plain way of recovering your data by scanning the volume of memory of your selection thus allowing you to choose the data to be recovered. This file is again saved to the chosen location. This utility does not perform diverse duties, but whatever minimum it does is neat.

  • Ontrack data recovery utility:

Sometimes your hard drive becomes logically dead ending you up with the loss of data. For this, you have to create a boot disk. Note that your Windows is still working. Boot the machine with this disk. This gives your hard drive a good system check. Select the partition that you want to scan thus beginning the process. On completion of the scan, you will receive a list of all your lost files. If you had not been able to create a boot disk before the problem encountered then, you can do this by using another machine.

So you see, there is no reason to panic. You can give a try to such methods before calling an expert. All the best!!!

What Can Cause Multiple Drive Failure?

The drives of your system contain valuable data and possess a huge capacity of storing such data. A drive failure can gross you in a bundle of tension and stress. If multiple drive failure causes a loss of data then one would be really panicked. There may be possibilities of data recovery but till then the apprehension circles around you. It is better to know the causes of drive failure so that you can take steps to alleviate it.

Causes of multiple drive failure:

There are various causes of multiple drive failure. Let us discuss one by one.

  • Hardware malfunction:

Sometimes your system fails to detect the drive. Before you could realize that you have a multiple drive failure, your system has rebooted in the middle of the process. The hardware malfunction can be the reason for this. If it happens after few days immediately installing of the drive, then it can be obvious that the manufacturer has delivered you the faulted product. These products do not undergo the testing phase and thus causing you a heavy deal.

  • Encounter of bad sectors:

Sometimes bad sections are encountered in the middle of the work. The moving parts are the reason behind this. The parts may degrade eventually damaging some efficient sectors of the drive thus leading to multiple drive failure. Also, if the heat rises up then some of the portions of the drive can fail to function. The entire system must have proper cooling arrangement to prevent this.

  • Fluctuation in electric power:

Voltage fluctuations usually occur in some areas leading to power failures. In such a case, the UPS fails to supply power regularly and efficiently. This can result in drive failure that becomes unable to take the frequent fluctuation in electrical surges. Either too high or too low voltage makes the drive turn silent on booting. So it is essential to supply only the required power to the system.

  • Virus attack:

Well, viruses are the uninvited guests for a computer system. They enter into any of the section of the system without notice and cause undesirable exploitation to the parts. The drive can also be a prey to a virus attack. Any corrupted file can ground the drive to divert from its functions and also gather all other parts to trouble. The malicious applications bring down the total drive system into malfunctioning.

  • Human error:

It is quite common to have human errors which can be caused due to multiple reasons. Some forceful closure of any running application or program can lead to disruption of the drive. Forced restart of the computer system can also be the reason of inviting multiple drive failure. If the operating system is installed in a wrong manner then, the drive is surely to fail resulting in loss of data and information. Sometimes you may need to have your computer completely formatted, and new software installed which would be quite a difficult job to do.

Hence, these are some of the causes of multiple drive failure. A piece of knowledge on these can help you prevent unwanted issues.

 

Recovered Data May Still Be Damaged

There are many cases when we find that the recovered data is corrupted or damaged. The reason behind that is separation of files at the time of removal. After removal, their assembled chain got distracted and led to failure or corruption in recovery of data. Whenever any program tries to recover this data by considering the starting location and size of the file, most of the fragmented files are not included.

This works fine if the files are stacked in a single and immediate block otherwise their blocks gets distributed around the disk, and the program becomes unaware and gets perplexed about their location. This is the reason that corrupted recovered data may have a bunch of correct and clean files, but it does not work in a sequential manner as that may belong to other dependent files.

If the files are in plain format, then there is a possibility to check the drive for inactive clusters and manually fix the files back together. But if the files are in binary format, then this process looks highly impossible. Even for plain text files, it gets difficult if the file has been edited and saved multiple times as then it becomes impossible to identify the real cluster that contains the last version of the file to recover.

Data Recovery Procedure

Data recovery program works mostly when the most recently used real files exists in the system. However, there are high chances that most of those files are either deleted or corrupted in the system yet some programs use an advanced path which looks out for all lost files instead of deleted, edited or got copied files. Most of the files contain signature as a part of its identity, which is being found at the start of the file, and contains a sequence of bytes. Due to this, program can analyze if the file is technically correct and identify the type of the file. Some data recovery programs search the disk and check to see the signature of the file types.

Downsides of Data recovery programs

With the help of such programs, we can find out most of the missing and deleted files. However, there are some downsides of this process to be taken into consideration:

  • It will provide the latest version of the file only and will not be able to provide a version history and also the directory information. It may also lead to delay in searching the process.
  • It does not know the exact size of the file due to which most of the files recovered gets rounded up to the nearest cluster
  • It has no capacity to recuperate separated files. It can only identify any copies of unused clusters
  • Since the scanning of the disk is done manually, a lot of files get reverted, and most of them are deleted files that have been removed quite a long time before. These results in more screening of the files received through initial scanning.

Why Storage Area Networks are Important for Big Companies?

The advent of technology and its use in different walks of professional life are not new. Technology hasn’t just made the world shrink but has also made operations easier. The ability to access information located far-off has made a lot of tasks possible that otherwise had never been so. The quick availability and sharing of information has become the need of the hour to meet the demands of this competitive world.

What are Storage Area Networks (SAN)?

Storage Area Networks (SAN) are highly secure, high-performance data storage networks which provide block-level storage. They allow sharing of storage resources and being used in clustered databases. The basic purpose of SAN is to enable the various storage devices to communicate with each other and enable the sharing of data within the network. It is much more than just storage and protection of data. Disk drives, RAID hardware, tape drives are the ones commonly used in SAN.

In a SAN, a single host computer is not the most pivotal. Here, all the servers are connected physically to all the storage devices. Direct access to the devices that store data rather than just accessing the servers and copying information is a useful facility provided by SAN.

SAN for companies

With the access to high-speed disks getting easier and a significant decrease in the costs involved, SAN was widely accepted by companies to utilize the information confined to different portals and places. The two basic solutions used by various small, mid-size and large companies are:

  1. Fiber Channel
  2. Small Computer System Interface Protocol (iSCSIP)

Advantages of SAN for large companies

Although SAN started out in use by large companies, even small and mid-size companies have also started using it to their advantage. Larger companies have offices located at different locations, and a lot of servers need to avail and share data with different servers. Larger the company, more the magnitude of data associated with the business. How well an organization fares in competition depend largely on how well an organization is inter-connected, and information sharing is carried out without any hassles. The basic advantages SAN offers to large companies are as mentioned:

  1. Data retrieval has become quick. Direct data transmission has enabled by SAN with minimal server intervention. A larger company has larger sources of information, a large number of servers that require quicker and easier data retrieval.
  2. Even if one of the servers is down for maintenance, others servers remain unaffected, thus maintaining continuous network operations.
  3. The extra costs for staging data temporarily from other servers have reduced. In SAN, one can directly access the devices used to store data. Thus, one doesn’t need to copy data from the server, and extra storage requirements are reduced, especially for larger companies.
  4. The extra costs of deployment are absorbed in a wide array as the scale of operation and implementation increases, thus making SAN favorable.
