Data recovery tool


Data recovery tool refers to the use of technical means through the tool to save the lost electronic data on the desktop hard drive, notebook hard drive, server hard drive, storage tape library, mobile hard drive, U disk, digital memory card, mobile phone memory card, etc. Tools for rescue and recovery.

ShenZhen OROD company provides global customers with low price, high quality, hard drive disk, mobile phone, Flash / CF / SD / SSD data recovery tool software products including: PC3000 UDMA, MRT, DFL, hard disk head replacement, hard disk replacement, hard disk motor replacement tools . Previous various hard disk data recovery adapter adapter, terminal line, ROM chip reader programmer tool.

Principles of data recovery:

Many people do not know that the data lost by hard disk operations such as deletion and formatting can be recovered, thinking that the data will no longer exist after deletion and formatting. In fact, after the above simple operations, the data still exists in the hard disk, and people who understand the principles of data recovery can retrieve the disappeared data in just a few clicks. Don’t think it’s unbelievable. After understanding the data in hard disks, USB drives, floppy disks and other media After the storage principle, you can also be a magician yourself.
To improve the success rate of data recovery, you need to first understand the principles of data recovery, and then select the appropriate data recovery device according to the cause of the hard disk failure. For the data loss caused by the logical layer failure and some physical layer failures of the hard disk, the data does not really disappear from the disk, but the system records the data storage location as blank in the hard disk file list, waiting for the next time to write data, As long as there is no write operation to this part of the area, the data will remain in the original location. In addition, data is not deleted due to partition loss, hard disk formatting, etc. Partition information can be retrieved through data recovery.
For most physical layer failures, bad track layer failures and firmware layer failures of hard disks, the principle of data recovery is different. Most of the physical layer faults of the hard disk need to be opened to replace the damaged corresponding accessories, and then the hard disk data can be extracted after repairing the hard disk; for the bad layer layer failure, the hard disk bad recovery area can be skipped through the instructions of the hard disk data recovery tool to obtain most of the hard disk data; For firmware layer failure, data can be recovered by writing back firmware or virtual firmware area.

Hardware failure data recovery
Hardware failures account for more than half of all data accidental failures. Often there are circuit failures caused by lightning strikes, high voltage, high temperature, etc., mechanical failures caused by high temperature, vibration collision, etc., physical bad track sector failures caused by high temperature, vibration collision, storage media aging, Of course, there is accidental loss of damaged firmware BIOS information.
The data recovery of hardware failure is of course first diagnosed, treated according to the symptom, first repair the corresponding hardware failure, then according to repair other soft failures, and finally restore the data successfully.
Circuit failure requires us to have a circuit foundation, and we need to have a deeper understanding of the detailed working process of the hard disk. Mechanical head failures require workbenches or workshops with a level of 100 or higher to diagnose and repair. In addition, some software and hardware maintenance tools are needed to repair the firmware area and other fault types.
RAID data recovery
The storage principle of the disk array is not explained here. Please refer to the array knowledge article of this site. The recovery process is to first eliminate the hardware and soft faults, and then analyze the array sequence, block size and other parameters, and use the array card or array software to reorganize. Restore data as usual.
