What does data recovery mean anyway?
- By: Roselee Bachleda
Data recovery is the process of recovering deleted or corrupted data on media such as a hard disk or a USB flash drive. Unfortunately, the topic “saving data” does not appear until it is often too late. Now the question is how to get to his data. https://outsourcedatarecovery.com/flash-drive-repair/ offers you the best solution.
What causes can lead to data loss?
Hard disks can be mechanical, electronic, or logical damage to the file system. The causes of data loss can be manifold. Let’s assume that the computer was not stolen or destroyed by fire. Then the reasons still range from an infestation by a computer virus over corrupt files up to a hard disk crash. Impending defects or signs of wear on the hard disk are detected early by SMART (Self-Monitoring Analysis and Reporting Technology). This industry standard is built into most computer hard drives and allows permanent monitoring of important parameters.
What should I do if the hard drive fails?
First of all, keep calm. There is nothing worse than a panicky computer user who believes that he loses all his data.
If nothing extraordinary is observed on the computer, weird noise from the hard drive or stinking smell may indicate a hardware defect. Then do not lend a hand, but bring the hard drive to a specialist. Data on such hard disks can only be reconstructed in the laboratory. Some of these specialist companies work with so-called clean room laboratories, where the concentration of airborne particles is kept as low as necessary. You can often fix other defects yourself. Here are two examples of logical disk defects.
Error Messages “Not Formatted” or “Unreadable”
This is due to a damaged boot sector. This logical defect can be remedied by manually editing the boot sector. This can be done with the help of a hex editor such as the free editor.
The active partition is not found
The operating system of the computer sees the hard drive as a logical drive. You can set up several logical drives (partitions) on a hard disk, which are managed in the Master Boot Record (MBR). If this table is damaged, the drives can no longer be detected, and the computer will not start in the worst case.
This can be remedied by correcting the table using the Recovery Console or Windows System Restore Options. Prerequisite for this is accessed with administration rights. First set in the BIOS that the computer is started from the CD. In the Recovery Console, the fixboot input creates a new boot sector on the system partition, and the fixmbr input repairs the master boot record of the boot partition. These commands are valid up to and including Windows XP. From Windows Vista just put a “bootrec /” in front of it.
A computer virus can also be the reason for data loss. I’ll talk about this particular cause of data loss in a later article.
Data recovery programs
If data has been accidentally deleted, there are programs that can help with data recovery. As a Program PC Inspector File Recovery example, I would like to call the free program PC Inspector File Recovery. It can easily recover deleted files on partitions with FAT 12/16/32 and NTFS. The found files can be reconstructed with original time and date. The prerequisite for data recovery is that the sectors concerned have not yet been overwritten with new data.
