There are many methods to perform data recovery and this article demonstrates some of them. All that you need to know is written below. We will show how you may recover it and not to lose other significant data and to resolve lots of other problems connected to information loss.
If you are an experienced client you should realize that HDD is not considered to be a safe place to store some very necessary information. You have to realize that HDD is a mechanism and any mechanism has got some operation life and that is not actually big. Except mechanical failures there are lots of various ways to lose the information saved on your HDD.
The programmers that attempted to resolve any HDD troubles with Windows 98 or earlier systems resorted to use of fdisk software and some other simple systems. Today the use of such solutions even by really experienced operators may lead to irreversible consequences.
File systems
File system defines the method which is utilized to save data on the face of the HDD. Free space is divided on some partitions with definite logical drives within. The most widespread file systems that are utilized by Windows are NTFS (NT File System) and FAT (File Allocation Table). Windows OS of the old generation and DOS used FAT-16. Modern Windows operates with FAT-32. The main difference between these systems is the capability of the system. It is difficult to believe that people used FAT-16 and had disks not bigger than 2 GB. Operating systems Windows 2000 and Windows XP are can work with FAT system meanwhile FAT is not the main system.
Surely all the Windows OS can work with FAT but NTFS offers significantly more possibilities. The other considerable advantage is that operator may set personal access rights for any file. All such systems use disk partition table and boot record which are stored in the first sector of every disk and determine which one is boot disk. In case the data in MBR is unreadable computer won't boot at all and some setors may be described as empty.
Data recovery
In case you decided to recover ntfs you shouldn't perform anything since moment you revealed the loss. Of course there are some system actions that are performed by the OS but it won't impact the restore result. In case you deleted something that was saved in recycle bin and you understood that you need that information do not write any data on the HDD. In case you marked the new partition the information from the erased one is still on the surface of the HDD.
The most inconvenient variant is when your HDD has just one partition. In such instances we should use another computer to connect the HDD. Operation with the other computer has lots of benefits.
Data recovery utilities
In case you don't have a possibility to replace the disk do not be tempted and do not reinstall the operating system. There are several software solutions that permit you to boot the computer under the control of the alternative operating system.
There are some freeware programs but usually they are not as efficient as shareware recovery files. The market is full of great propositions and such kind of programs is considered to be inexpensive.
