More than one hundred different companies offer data recovery software. Due to the large selection it is not easy for one to determine which type of data recovery software to use. All data recovery options will depend upon the type of operating system is installed on the computer. The system could be Windows or Unix and not all software will work on each given system. However, it is important to look at the systems themselves to see which operating system has the greatest advantage for data recovery.

When it comes to data recovery it is important to select the right system for you. There are many differences between the Unix Data Recovery Houston system and Windows data recovery. Window users face many obstacles with security issues as it is a hacker’s primary target. A Unix system is under constant monitoring from a community of developers making security risks low. It is likely that both systems at some point will need to undergo some data recovery. The recovery of data from a Unix system will differ from the recovery in a Windows system.

Cost efficiency


Unix data recovery and systems will vary in prices. This is because of the number of vendors offering the product. Windows data recovery and systems will cost around two hundred dollars (with upgrades costing a bit more).

Development and distribution

Windows data recovery platforms have been developed by Microsoft and are distributed by Microsoft. Various vendors, such as AT&T and a few non-profit organizations, develop Unix data recovery platforms. This makes access and prices vary greatly. The main distributors of Unix data recovery and systems are IBM, Hewlett Packard, and Solaris.

Usage of data recovery

Windows data recovery and systemsare used for desktop computers, laptop services, and certain phone systems. The Unix data recovery and systemsare used for workstations and desktop computers, Internet servers, and by major finance companies.

Type of data recovery needed

Discovering which system is a better fit for your needs will depend on the type of data loss and user friendly techniques available. Windows is known for having a user-friendly system that enables smooth access of data recovery. Not all Windows systems offer the same kinds of data recovery. If there is a file deletion with your data loss, then Windows may not be ideal. Users are unable to save or install any new information to the drive for data recovery in Windows. This means all data recovery work must be done using a second computer.   All commands are originating from one location.

Unix data recovery and Unix systems face a different challenge. The Unix system is not as user friendly as the Windows system, but the Unix data recovery stands a better chance of data retrieval. This is especially true when dealing with data deletion, as there is no need to worry about overwriting old data with new data when installing software.

Overall, there are many factors to consider when deciding between a Unix and a Windows system. If you have a Windows system, a second computer will be needed to perform a data recovery. With a Unix system, the user will have a better chance of data recovery but can vary in cost greatly and will require more knowledge on the user’s part.

Logical odds and issues require software-based solution modules. Mechanical, as well as electronic issues may affect the hard drives. Under such a situation, it is necessary to address the physically damaged hard drive for rectifying the mechanical issue.

The main characteristics

It is also a fact that logical issues are more frequent than mechanical issues of physical damage. The former is easily rectifiable by the logical data recovery process. The process doesn’t require manual repairing of the damaged storage device. The following happens to be the defining hallmarks of logical recovery procedure:


  • First, the repairer seeks to retrieve and rebuild a corrupted file, one that has been either damaged by a virus attack or by the error of a user
  • As said before, the operating system will recognize the drive, but it will come with an error message. The message happens to be a sure shot indication of the data loss that has taken place.
  • So, the repairer seeks to retrieve the user error. The software solution used, either tries to address the human error that has accounted for the lapse of the information, or tries to make a virus scan.
  • That’s because malware infiltration is also responsible for disrupting the data storage device, and causing loss of information.
  • The objective of the process is to locate and retrieve the lost data, but not to have those changed. The software-based recovery solution should be such that it aids the recovery and the retrieval process, instead of altering data that has already been stored.

Reasons for seeking professional help

There are two types of hard disc failure. On the one hand, you have the oft-repeated logical failures, and on the other hand, you have the failure that is mechanical in nature. The latter is less frequent than the former. If a mechanical failure occurs, you may need to have the disc rebuilt and reset. Besides having the disc repaired, it may also be necessary to have the core logical system of the file addressed. When a mechanical error takes place, it also tends to upset the logical system of file management. But then, you will require to accessing, as well as, reading the data. So, the application of a software-based solution may also be necessary besides tending the mechanical issue that has taken place.

Nature of the drives

The drives have electro-mechanical orientation, and they keep spinning, on a regular basis. Even if the computer system remains idle; then also, the hard disc will keep spinning at their fixed RPM rates. Mechanical failure may disrupt the normal functionality of the drive, but then the crucial question is, when and under what circumstances is it necessary to rebuild hard drive?


  • Large numbers of extraneous factors are responsible for disrupting the hard drive’s functionality. The sudden surge in the power may be a cause for causing hard disc disruption. As a result of this, the file system may get corrupted.
  • The head of the drive may suddenly crash, owing to the mechanical collision. Then, there are other extraneous factors including fire, flood, and sudden fall. All these can cause mechanical disruption
  • Some of the firmware programming may be more susceptible to mechanical damage, than the others.
  • When it comes to the question of rebuilding the drive, then there are two distinct angles to consider. The prospect doesn’t necessarily implicate the mechanical data recovery process. You may have a logical rectification to make, as well in the course of rebuilding.

The process of rebuilding

In fact, the entire concept of the rebuild hard drive service includes an extensive angle. As said before, you may have a logical issue to address, as well. In that case, you can embark upon a DIY project. That’s because the prospect may only require the replacement of the controller card. After this, you can have the system reprogrammed, with the help of relevant software. But then, it is mandatory to take professional help to replace the precise parts of the drive including the read and the write head measures.

You may suddenly come across a situation of a crash where the components are crashing. The drive stops clicking and the motor cease to function. In that case, the best thing to do is to refer the issues to the recovery specialists. The engineers and the repairing technicians know how to go about the process in a room that is free from the dust and debris. The drive needs to be opened for replacing the damaged components. The professional process of hard disc rebuilding and recovery start off with copying the image of the malfunctioning disc and ends with the transfer of the retrieved data.
