Different users have different views about what the Clean Rooms are and why they actually are important for data recovery. Fundamentally the Clean Rooms are safe and controlled laboratory environments, which are designed to avoid minute airborne contaminants that could be dust or even pollen.

For data recovery firms, the Clean Room is a necessary asset as hard disk repair needs exceptionally clean and secure working conditions. The airflow in Clean Room is completely clear. The Clean Rooms are also free from other harmful environmental factors as humidity, ESD (ElectroStatic Discharge), smoke, high temperature (viz. due to direct sunlight) or pressure.

The Clean Rooms are divided into different classes. With every class limiting permitted different number of dust particles per cubic meter and the maximum size of dust particles. Thus the Class 1 Clean Rooms allow maximum 1000 particles for each cubic meter.

The Clean Rooms are mainly used in semiconductor manufacturing, pharmaceuticals, hard drive recovery companies and biotech industries. The data recovery firms use Clean Rooms to ensure protected environments for storage media internals as hard drives and SSDs (Solid State Drives) in order to avoid further damage to disk internals that actually store the data viz. hard drive platters.

Why are the Clean Rooms necessary for physical Data Recovery?

The hard drive internals specifically hard disk platters, are extensively susceptible to damage from dust particles once opened. Even a microscopic dust particle could damage the sensitive platters and may separate the stored data for life. To avoid these situations, Hard Drive Recovery companies use Clean Rooms.

Hard drive technique continues apace with the drive being able to store a large amount of data but it becomes more compactly packed on disk platters and the possibilities of further damage are high. So, it would be better to find out a trusted and experienced Hard Drive Recovery company with high standard Clean Rooms and send your hard drive to it.

Along with a certified Clean Room, absolute and timely hard drive recovery also needs expertise of skillful and experienced data recovery professionals. Thus, you should send your hard drive to a data recovery company that has a team of trained and qualified recovery specialists.

In general terms, firmware is the set of instructions i.e. program that is embedded on an electronic device and controls it. For hard drive, this is a program that is built into it and keeps control of it. It is meant to run the hard drive as per the logic required. It is simply defined as software on hardware. It is a software program which is found on PCB (Printed Circuit Board) flash memory. The typical functions of firmware include configuring hard drive while startup, interacting with hard drive’s components while working and correctly powering down hard drive. If the firmware gets corrupt, hard drive will become inaccessible. In the absence of data backup, it causes data loss and Data Recovery service becomes necessary.

While the firmware is corrupt, the system can not access hard disk data. As the nature of the issue is, the corrupt firmware needs to be reprogrammed by low level programming techniques. These techniques usually require experienced programmers.

The symptoms of hard disk corruption differ as per the extent of damage.

• If the extent of damage is high, BIOS may fail to recognize such hard drive.
• In case of partial corruption, system may run slow or hang while booting.

Low-level reprogramming of firmware is the solution to correct the issue. Data Recovery experts affirm that it is a safe procedure, if done properly and by following the proper guidelines. Such failed hard drives need to be checked through suitable procedures that include safe dissection of hard drive in Clean Rooms. Clean Room surroundings give an appropriate lab environment that is completely free from moisture, dust, ESD (Electrostatic Discharge), high or low temperature and pressure etc. It is meant for environmental problem free work routine so that the sensitive disk internals remain safe.

Hard Disk Recovery is performed for extracting data in other cases also that can be mechanical or electronic failures. Data in such cases is recovered using definite procedures, which involve replacing the damaged internals and applying careful and technical data extraction processes. Recovery service is the solution in each physical failure case.

The dual boot systems enable you to use features of two different operating systems on a single computer system. A user can install two different operating systems starting from the older one. It is preferred to partition the hard disk first and create at least two partitions. However, problems might occur when you install an older operating system like Windows XP on a Windows Vista system. In such situations, you receive an error message at system startup and data saved in the hard drive becomes inaccessible. If you have not maintained any updated data backup, you need to use advanced Data Recovery Software to access the data.

Consider a practical scenario, where a user has a Windows Vista based system and he installs Windows XP on a different partition. After the installation process is complete, when the user restarts the computer, he encounters the below error message:

“A disk read error has occurred. Press CTRL+ALT+DEL to restart.”

The user receives the same error message each time he restarts the computer system after pressing CTRL+ALT+DEL key combination. After the above error message appears, the data saved in the hard disk becomes inaccessible. The main cause of the above error message is that the user has installed a version of Windows that is older than Windows Vista. The problem arises because the Setup process in the previous version of Windows attempts to overwrite the boot sector on the main Windows Vista partition.

Resolution:

To resolve the above error and access the data saved in the hard drive, the user needs to follow these steps:

• The user should install earlier Windows XP on the primary boot partition.
• Then the user needs to install Windows Vista on a new partition.
• If the user wants to start from more than one Windows operating system, install the earliest version of Windows first, and then install the later versions in their order of release. Here, the user needs to firstly install Windows XP operating system and then Windows Vista operating system.
• The user needs to install each operating system according to the standard installation procedure.

To access the data saved in the hard drive, the user needs to use powerful Data Recovery applications. Data Recovery Software employ effective and high-end scanning methods to recover and restore inaccessible data from hard drives.
