Detailed Product Description: | Several hard disk data recovery, mistakenly formatted hard drive data recovery in the state of the DOS version, the format operation format in the default state have been established for the recovery of formatted disk information, in fact, the disk the DOS boot sector copy all the contents of the fat partition table and the table of contents to the last few sectors of the disk (because the latter sector is rarely used), the contents of the data area is not changed. We all know that in the DOS era, there is a very good tool UnFormat, it can be restored by the Format command to clear the disk. If the user is using the Format command in DOS mistakenly formatted a partition, you can try to use the command. However UnFormat can recover only the local hard disk and software drive, network drive can not be restored. UnFormat command in addition to the above anti-formatting features, it also re-repair and the establishment of the damaged partition table on the hard drive. But currently UnFormat has seemed a bit "powerless", and then use it to recover formatted partition has been a bit out of date, we can use a variety of data recovery recovery software recovery software, such as the use Easyrecovery 6.0 Finaldata2.0 easy data recovery. DOS also provides a miror command is used to record the information of the disk, use the recovery for formatted or deleted, this method is also more effective. Zero track damage data recovery hard disk's master boot record (MBR), the zero track. MBR located on the hard disk cylinder 0 track 0 sector 1, which holds the hard disk master boot program and partition table. Belonging to the hard disk master boot program in a total of 512 bytes of hard disk master boot record sector, 446 bytes, 64 bytes belong to the hard disk partition table (DPT), two bytes (55 AA) is the partition end flag. Zero track once damaged, will enable the hard disk master boot program and partition table information will be devastated, resulting in the hard disk does not boot. Track 0 bad judgment: the system self-test pass, but the startup partition loss or loss of C drive directory, regular "creak ... creak" hard disk seek sound, run the SCANDISK scan C drive, in the first cluster a red "B", or Fdisk can not find the hard disk, DM dead on the track 0, such a situation that the zero track damage! Zero track damage is one of the hard disk damage, but it is very important, therefore, once destroyed, it will have serious consequences. 0 track damage, in accordance with the ordinary method is unable to make the data complete recovery, hard disk, usually 0 track damage by the PCTOOLS DE disk editor (or DiskMan) 0 tracks deflection of a sector, use one track to to be used as track 0. Data can Easyrecovery to follow the cluster recovery, but the data can not be guaranteed to be fully restored. Data recovery, partition table damaged hard disk master boot record (MBR) where the sector is also a virus focus attack places, by the destruction of the main boot sector of the DPT (partition table), and can be easily damaged hard disk partition information, achieve the purpose of the destruction of data. The damage to the partition table is partitioned data is destroyed and the records were destroyed by. So, we can use the software to repair. Under normal circumstances, after the hard disk partition you want to back up a partition table to the disk on the floppy disk, CD-ROM, or removable storage activities. In this regard, the domestic famous series and Rising antivirus software KV3000 provide a complete solution. However, do not have a backup hard disk partition table Although The KV3000 also provide a repair, but the success rate is relatively we should be much lower. On the recovery partition, Norton Disk Doctor NDD is absolutely the strongest tool can automatically repair partition loss, can rescue the data in the floppy disk in a bad area, move to other mandatory read out blank sector. In the case of a hard disk crash or abnormal, it may bring a glimmer of hope. Problems with the boot disk, run NDD, select Diagnose diagnose. NDD would be hard to carry out a full scan, if there is a mistake, it will prompt you, then as long as the software prompts to select restoration projects can be, and these problems can be easily solved. In addition, the Chinese people are very familiar with Disk Utility DiskMan rebuild the partition table with a very useful feature, used to repair the damage to the partition table is the most appropriate. If the hard disk partition table is severely damaged partition to adjust software (or virus) will cause the hard disk and system paralyzed serious consequences DiskMan, unspoiled by the partition boot record information to re-create the partition table. As long as the menu toolbar, select "rebuild the score sheet DiskMan start searching and re-partition. The use of the process, DiskMan will first search for the hidden sector 0 cylinder 0 head start from 2 sector, partition table to find the virus had been dragged. Then you want to search each of the first sector of the head. Throughout the search process is the use of "automatic" or "interactive" in two ways. Automatically by retaining found each partition, apply in most cases. Interactively found that each partition will prompt user to choose whether to keep. When the partition table using the automatic renewal of the event does not correct the fault, we can interactively re-search. However, rebuilding the partition table function also can not guarantee to do repair hard disk partition table. So remember to "beg nobody who seek its own," or protect their own hard drive! Avoid hardware damage and viruses, be sure to do a backup of the partition table; If you do not do backups, download a DISKGEN software and tool options selected backup partition table, general default is backup to the floppy drive above , if you do not have a floppy drive, it is necessary to change the path, output to the hard disk directory. Then you should burn the backup files to a CD or copied to the U disk, do not put the hard disk Oh, as a kind of effect with no backup! 4, accidentally deleted after the data recovery in the computer to use the process of our most common data recovery data recovery after accidental deletion, but we must remember that at this time, do not revert to the partition or disk write information because those newly deleted files recovery is most likely. In fact, when using fdisk to delete the hard disk partition, superficial data in the hard disk has completely disappeared, formatted the hard disk will display invalid drive. If you understand fdisk works, you will know, fdisk just to rewrite the master boot sector of the hard disk (0 side 0 sector) in. Specifically is to remove the hard disk partition table information, any hard drive partition data are not changed. Delete and formatting operation for the data portion of the file, essentially did not move, so, give the file to provide the possibility of recovery. As long as we use undelete software (it works through control partition table to recover files), users can easily achieve the purpose of file recovery. Mistakenly formatted with the recovery of accidentally deleted use basically no big difference, as long as there is no partition hard disk (Fdisk command disrupted for less than 40G hard disk partition using FDISK command, is still very convenient and practical, all start have on the disk, the motherboard supports no problem), the file you want to restore the occupied cluster is not occupied by other files, so that most of the data before formatting can be restored. And if your Windows system can also be used normally, then the easiest recovery method is to use the Windows version of EasyRecovery software, restore hard disk data is very powerful, not only to restore the files removed from the Recycle Bin, but also to restore formatted FAT16, FAT32, or NTFS partition files.
