Hard disk data recovery tools are now widely available. More and more companies offer hard drive data recovery tools, knowing that more and more people use computers with hard disks that are generally once a crash once. The hard disk data recovery tools designed and developed in the hope that the lost data can still be recovered, although the computer system in their first eight inaccessible.
The truth is, if the data are damaged or removed from the hard drive by an accident, that the data are not lost. It is simply stored somewhere, and the hard drive data recovery tools can do something to get them back.
If you are currently experiencing data loss, you want your important files. You can contact us with an expert to help you to recover your lost data. But, if you want to know what hard drive data recovery software available, and often used by hard disk data recovery experts, pay attention to the following:
PC Inspector File Recovery
Depending on how your files are lost, it can be difficult to get them back. But, you do not worry because PC Inspector File Recovery to the rescue. The PC Inspector File Recovery is actually a hard drive data recovery tool that recoverd files and lost partitions automatically, even if the boot sector of your machine is damaged or removed. Another great feature of this hard drive data recovery tool that is PC Inspector File Recovery can recover data even when the header entry or the file no longer available anymore. And besides, this hard drive data recovery tool even save the recovered files on network hard drives.
Restoration
Restoration is a harddisk data recovery tool, which works mainly for the salvation of your accidentally deleted files and permanent. It is also noteworthy that Restoration is a hard drive data recovery tool that can live on a floppy, so it leaves no trace of its activities. Furthermore, the program also free.
Restorer2000
Restorer2000 is a different hard drive data recovery tool so powerful to recover accidentally deleted files from your hard drive. This hard drive data recovery tool is able to retrieve the lost files, if the data loss is a result of corruption or reformatting the hard disk. This is actually why Restorer2000 is often seen in a number of hard disk data recovery tool reviews, as one of the most powerful recovery and data recovery software solutions available on the market.

With the development of science and technology, 160G, 250G hard drive in the ordinary users have been commonplace. However, the use of a long hard process, we also suffer from hard drive to keep the risk of error, ranging from the hard drive data loss, heavy scrap the entire hard disk, resulting in unpredictable and potentially severe consequences. Methods to be adopted to solve the common hard drive data loss failures, as a user is very concerned about the issue.
A hard disk partition
For the hard drive in your hands, the first thing to do is partition. Hard disk partition whether it is reasonable to work beyond the direct impact on the convenience and data security. We can often see the hard disk partition table errors were also the most serious errors, different errors might lead to different types of losses. If there is no active partition flag, then the computer does not start. However, after the boot floppy or CD-ROM drive can read and write, reset the active partition by fdisk can be repaired. If it is a partition type of error will cause the loss of a partition.
Under normal circumstances, after the completion of the hard disk partition, will form three kinds of forms of regional state; that is the primary partitions, extended partitions and non-DOS partition.
Africa DOS partition on the hard disk (Non-DOSPartition) is a special district form, which is a separate hard drive in an area carved out for another operating system used on the primary partition of the operating system is concerned, yes 1 is divided out of storage space. Only non-DOS operating system in order to sub-district management and use of this piece of storage area, non-DOS partition outside the system, the sub-region generally can not access the data.
The primary partition is a relatively simple partition, usually located on the top of a hard disk area, constitutes a logical C disk. One of the primary boot program is a part of it, this section is primarily used to detect the hard disk partition program correctness, and to determine active partition, is responsible for guiding the activities of the right to be transferred to the DOS partition or other operating systems. This section will be unable to process damaged boot from the hard drive, but after the soft areas or light areas on the hard drive can read and write.
The concept of the extended partition is more complicated, and very easily lead to the hard disk partition and logical disks confusion; partition table as the fourth bytes of the value of partition type, the normal bootable DOS partition larger than 32mb Basic value of 06, the extended DOS partition value is 05. If the basic DOS partition type to 05 can not start the system, and can not read and write data on them.
If DOS does not recognize 06 types of change, such as efh, the DOS Partition that change is not a DOS partition, of course, can not read and write. Many people take advantage of this type of value is to achieve a single partition encryption technology to restore the original values of the right type can make the partition back to normal.
The partition table there are other data are used to record the start or termination of the address of partition. These data will result in damage to the partition of the confusion or loss of, generally can not be manually restored, the only way is to backup the data to re-write the partition table back, or from other conditions the same type and the same hard disk partition to obtain data on the partition table, otherwise will result in permanent loss of other data.
As the computer operating system, partition table reserved only for the 64 bytes of storage space, while the parameters of each partition occupies 16 bytes, so the operating system only allows four partitions of the data is stored, the actual use of the four Logical Disk often do not meet the demand; We often say that extended partition hard drive, it’s just a pointer pointing to the next one partition, this pointer structure will form a one-way linked list. So, once the one-way linked list problem occurs, will result in the loss of logical disks.
Second, the hard drive data recovery
1, mistakenly formatted hard disk data recovery
In the DOS version of the high state, the formatting operation format in the default state, have been established for recovery formatted disk information, is actually the disk DOS boot sector, fat partition table and copy all the contents of the table of contents to the last few sectors of the disk (because the latter sector is rarely used), while the contents of the data area has not changed. We can use a variety of data recovery software to recovery, such as the use of Easyrecovery6.0 and Finaldata2.0 other recovery software may facilitate the conduct of data recovery work. Another DOS also provides a miror disk command is used to record the current information for the formatted or deleted after the resumption of the use of this method is also more effective.
2, zero track damage of data recovery
Hard disk master boot record area (MBR) on the zero track. MBR in the hard disk cylinder 0 track 0 sector 1, which holds the hard disk master boot program and hard disk partition table. In a total of 512 bytes of hard disk master boot record sector, the 446-byte belongs to the hard disk master boot program, 64 bytes belong to the hard disk partition table (DPT), 2 bytes (55AA) belongs to partition end marker.
Zero track, once damaged, will the hard disk master boot program and partition table information will be severely damaged, leading to the hard disk can not boot. 0 Track damage to determine: the system self-test pass, but the startup partition C drive directory is lost or missing, a regular hard disk, “creak … creak …” and seek sound, run SCANDISK scan C drive, in the first cluster A red “B”, or Fdisk can not find the hard disk, DM died in the 0 track, on which this case is zero track damage!
Zero track damage to belong to one of the hard disk bad sectors, but its location is important, so once they are damaged, it will have serious consequences. Usually 0 tracks damaged hard drive, the DE can be PCTOOLS disk editor (or DiskMan) to make a sector 0 track deflection, using a track to track to be used as a 0. The data can be Easyrecovery to cluster according to recover, but the data are not guaranteed to be fully restored.
3, partition table repair damaged data
The hard disk master boot record (MBR) where the sector is also the focus of attacks where viruses, by destroying the main boot sector of the DPT (partition table), it can easily damage the hard disk partition information to achieve the purpose of the destruction of the data. The damage to the partition table is damaged Ershi partition the data records are destroyed. Therefore, we can use the software to be repaired. After the hard disk partitions to back up a partition table to floppy disks, CD-ROMs or removable storage disk activity.
In the recovery partition on the NDD Norton Disk Doctor is absolutely powerful tool that can automatically repair partition is lost, and so on, you can save data in the floppy disk bad area, forced to read out the blank, after moving to other sectors. A hard disk crash or unusual circumstances, it may give the user a glimmer of hope. In the event of problems, with the boot disk, run the NDD, select Diagnose diagnosis. NDD would be hard to conduct a comprehensive scan, if there is wrong, then it will give you prompt, and then only according to the software can be prompted to select a restoration project, and these problems that it can be easily solved.
In addition, we are very familiar with the Chinese Disk Utility DiskMan, in rebuilding the partition table has a very useful feature, used to repair the partition table, but the damage is the most appropriate.
However, the reconstruction of the partition table functions are not guaranteed to achieve 100 percent of the repaired hard d
isk partition table. So remember, “Who is not as seeking its own demand” or to protect their hard bar! Try to avoid hardware damage and virus intrusion, we must do a good job of backup partition table; If there is no backup, please download a DiskMan software, and then in the tool options, select the backup partition table, the general default is backed up to floppy above. Then you should not take this backup file to burn to CD or copied to the U tray, do not put hard disk, so there is no backup with the effect of a sample of!
4, data recovery after the accidentally deleted data
In the computer process, we use the most common is accidentally deleted data recovery after the data recovery, but at this time to remember, do not revert to the partition or disk to write the information, because newly deleted files are most likely to resume.
Indeed, when the hard disk using fdisk to delete partitions, the superficial is the hard drive data has completely disappeared, without formatting the hard disk will be displayed when entering an invalid drive. Specifically, that is to remove the hard disk partition table information, while the hard disk of any partition data are not changed.
As with the formatting operation to delete the data section of the paper essentially does not move, so, give provide the possibility of file recovery. As long as we use some undelete software (it works by comparing the partition table to recover the file), users can easily achieve the purpose of file recovery. At the same time mistakenly to restore accidentally deleted formatted the same way in the use of basically no big difference, as long as no use Fdisk command disrupt hard disk partition (using FDISK command to partition the hard disk of less than 80G, is still very convenient and practical, and All have a boot disk, motherboard support is no problem), to restore the file is not occupied by the clusters occupied by other files, so that most of the data before formatting can still be restored.
If your Windows system can be used normally, then the easiest recovery method is to use Windows version of EasyRecovery software, hard disk data recovery function is very powerful, not only to restore the files removed from the Recycle Bin, but also to restore the format of the FAT16, FAT32, or NTFS partition files.
