Welcome to my “Hard drive recovery new jersey.”
We may have encountered such a thing, just empty the garbage station in the morning, but suddenly reminded of which a document is particularly important, how can this be done? There may be system damage to the virus, the hard disk partition table or file allocation table was rewritten by the virus, but the hard disk on your years of hard work. At this time we need to restore the data, and there are many domestic specialized in data recovery business of professional firms. But our hard disk files were mistakenly deleted, partition loss, virus damage, etc., through some data recovery software itself can be resolved. The following details on the principles of data recovery and some commonly used data recovery methods.
Hard disk use and maintenance precautions.
1. Regular use of Windows comes with the disk finishing tool Defrag or other such as Vopt, Norton Speed, and other disk defragmentation optimization tools to organize your hard drive data, generally one month finishing time, you can improve the hard disk access speed. Even if the accident, but also improve your data file recovery probability!
2. The hard drive is a high degree of precision mechanical and electrical equipment, although the hard drive impact greatly improved, in order to safety and insurance must be lightly put; installed in the host hard drive when the four fixed positions should be fixed with a fixed screw. After the boot cannot move the host. Off 1 minute hard drive after the motor stopped, before the move, which is the original small hard drive has a special head homing procedures to provide the reasons for the use of the machine. Hard disk indicator light is flashing when the power cannot be turned off so the operation may damage the hard disk.
3. Normal hard disk running noise is small, there will be hard disk read the disk even when the "blah" sound. If your hard drive is running when the sound is large or abnormal, this is usually a precursor to the failure, this time should be the timely backup of important data to prevent the accident!
4. GHOST used to restore the partition, be sure to select the target partition, otherwise, it may lead to loss of the district or important data cannot be restored. It is recommended to restore the partition before the partition plus Lable so you can distinguish the target partition, will not lead you to choose the wrong target partition caused unnecessary losses.
5. When formatting a hard disk using the Format command, it is a good idea to use the Fdisk / Status command to view the partition information of the hard disk, and if there is an NTFS partition, it is possible to prevent the data from being dropped.
6. To take full advantage of the characteristics of the partition, data files are generally not placed in the C area and the system area, because the C area and the system area is the accident-prone area.
The reason for the loss of hard disk data
1. The type of software failure
Accidental electromagnetic interference caused by data loss or damage; system error or paralysis Causing the file to be lost or destroyed.
Software phenomenon is generally the performance of the operating system is lost, cannot start the system, the disk read and write errors, can not find the required files, the file can not be opened, the file is opened after the garbled, hard disk no partition, suggesting that a hard disk partition is not formatted The
2. The type of hardware failure
Disk scratch; head deformation; magnetic arm break; head amplifier damage; chipset or other components damaged.
Hardware failure is generally manifested as the system does not recognize the hard disk, often a "Kacha Kacha" magnetic group impact or motor does not turn, no sound after power, the head is not allowed to cause errors such as reading and writing. Some of the specific performance is as follows:
① boot, the system did not find the hard disk, but also without any error. Note that some motherboards in the hard disk failure will give the corresponding message and prompt code. We are in the exclusion of the normal power supply hard drive, power cord connection is correct, the data line is installed correctly, the data line is no quality problems, it can be determined that the hard disk is broken.
② start the system time is particularly long, or read a file, run a software often an error, or to go through a long time to operate successfully, during which the hard disk constantly read and issued a harsh murmur, this phenomenon means that the hard disk Disk or hard.
