Data Recovery

Visions Business Services can help you recover lost files on your computer. VBS technicians have the technical knowledge and experience in performing data recovery and, in most cases, can retrieve much of your lost data. Due to the nature of data storage, Visions Business Services cannot guarantee that your data can be recovered, but we can give an honest assessment of your particular situation.

Data recovery the process of finding and restoring data, in which there is some risk that the data may not be able to be recovered or maybe recovered in an unusable form. Your best bet is to reduce the danger in data recovery by being proactive:

  -Backup all the data on your hard disk.

  -Prevent the equipment from being damaged or damaged again.

  -Dont write anything to the device that you want to recover data from.

  -Pay attention:try to get detailed information on how the data was lost.

Data recovery means retrieving lost, deleted, unusable or inaccessible data that was lost due to various reasons. Data recovery not only restores lost files but also recovers corrupted data. On the basis of different reasons for the loss, VBS can adopt different data recovery methods. There are software and hardware reasons that cause data loss, while we can recover data by software and hardware ways. Being different from prevention and backup, data recovery is the remedial measure. The best way to insure the security of your data is to backup regularly. To operate and use your data according to the normative steps, you can reduce the danger of data loss.

The scope of data recovery.

There are many forms and phenomenon on data problem, we can divide the objects or scope of data recovery according to different symptoms.

1. System problem: The main symptom is that you cannot enter the system or the system is abnormal or computer closes down. There are complex reasons for this, thus we need adopt different processing methods. Reasons for this symptom may be the key file of system is lost or corrupted, there is some bad track on hard disk, the hard disk is damaged, MBR or DBR is lost, or the CMOS setting is incorrect and so on.

2. Bad track of hard disk: There are logic and physical bad track. Logic bad track is mainly caused by incorrect operation, and it can be restored by software. While physical bad track is caused by physical damage, which is real damage, we can restore it by changing the partition or sector. When there is physical bad track, you better backup your data for fear that the data can not be used any more because of the bad track.

3. Partition problem:If partition can not be identified and accessed, or partition is identified as unformatted, partition recovery tools can be used to recover data.

4. Files loss: If files are lost because of deletion, format or Ghost clone error, files restoring tools can be used to recover data.

5. Password loss: If files, system password, database or account is lost, some special decryption tools that correspond to certain data form can be used to recover data.

6. Files repair: For some reasons, some files can not be accessed or used, or the contents are full of troubled characters, the contents are changed so as they can not be read. In this condition, some special files restoring tools can be tried to restore the files.

Data loss

Generally, There are two main reasons for data problems: software reasons and hardware reasons.

Software reason

Virus, format, mis-partition, mis-clone, mis-operation, network deletion, power-cut during operation all may be the software reasons. The symptoms are usually mis-operation, read error, can not find or open file, report no partition, not formatted, password lost and troubled characters.

A: Computer Viruses: some malicious virus programs will destroy data, overwrite, or erase data contents.
B: Mis-format: fast or completely format partition, thus changing the file system form (NTFS, FAT32) of the partition.
C: Mis-Clone: when backing up the hard disk, mis-clone or overlay the original data on hard disk.

For these, VBS can use software tools to recover data. Soft recovery means data can be recovered by software.
The following are prompts that the system can not start up normally:

  -Invalid Partition Table: Invalid partition table information.

  -Missing Operating System: 55AA mark in DOS boot sector lost or DBR   corrupted.

  -Disk Boot Failure: System file read failure.

  -Bad or missing command interpreter: Can not find command.com file or COMMAND.COM file corrupted.

  -Invalid system disk: DOS boot record corrupted.

  -Type the name of the command, Interpreter: DOS partition mark in partition table error or COMMAND.COM file lost,    corrupted.

  -Error Loading Operating System: Main boot startup program read boot sector unsuccessfully.

  -Not found any active partition in HDD: Active partition mark in partition table changed as inactive partition mark.

Hardware reason

Sometimes data loss is because of hardware, such as bad sector in hard disk, power cut, head damage, circuit panel problem, etc. When your hardware has some problems, you probably will find: the speed of hardware become slow, you cannot operate successfully; you cannot read data, etc, which are most often physical bad track failures. Correspondingly, data recovery in hardware fix is considered as hard recovery, such as memory medium damage, track damage, hard disk scrape, head damage, electric machinery damage, chip burnout and so on.. The most distinct feature or difference between soft recovery and hard recovery is whether the memory medium itself can be normally accessed by fixing or replacing parts.
