For files deleted on your computer, normally, if you don't have a special deal, the system simply deletes the file name in the Files allocation table, and the real data is still on disk. With some data recovery software, it's easy to recover files that have been called deleted. The partition assistant has the ability to erase the disk, it can completely delete t

We know that the security problems are becoming more and more serious, and there are many information leakage problems in some places. For example, a swap partition. The swap partition frees up some of the space in the hard disk space when the system's physical memory is not available for use by the currently running program. The freed space may come from programs that have not been manipulated for a long t

, so the system will be caught in the repeated error correction, but can not repair the dead loop, eventually causing the system to think that the block address is damaged (bad block), but The SSD itself does not remap the physical block address corresponding to these logical block addresses (LBA), so this failure occurs, but the actual storage unit is not corrupted.Some of the new SSD users, encountered the above situation, generally think that the SSD has been a problem, must be repaired throu

The partition assistant has the ability to erase the disk, it can completely delete the data on the disk, so that the data on the disk can not be erased or deleted by other data recovery software, which can achieve high data confidentiality. For example, you do not want to use old disks that need to be sold, yet worry

hard disks to form a logical hard disk with acceleration, automatic backup, data corruption recovery and other functions.To meet the needs of different working environments, RAID technology is divided into the following RAID 0-7 Count 8. Each array has its own advantages and disadvantages, such as a RAID 1 array that emphasizes the security of the data on the

proved that low-level hard disks with physical bad sectors will be decommissioned. For logical bad sectors, there is no need to use a low-level program as a repair method. In addition, the low level will completely erase all data in the hard disk, which is irreversible. Therefore, low-level disks can only be used as a

. This can correct some defects. For example, because the sector data does not correspond to the validation value of this sector, an ECC error is usually reported ). If it is not due to magnetic medium damage, it is very likely that the sector data will be re-matched with the validation value of the sector after being cleared, to achieve the effect of "repairing" the sector. This is the most basic operation content for each type of low-level tool and each type of
