Reading current text you will search out a great deal of information about data recovery and other actions performed to restore data. We will demonstrate how you may recover it and not to lose other important information and to solve lots of other complexities connected to data loss.
If you asked for help of some professional he would claim that it is not reasonable to save all the significant information just on the HDD as it is simply to lose it. Unlike CDs and other kinds of data carriers HDD is a mechanism that wears out like any other mechanical system. In case there is a mechanical problem sometimes that is not possible to restore any data as HDD becomes fully invalid.
The operators that tried to work out any HDD troubles with Windows 98 or earlier systems resorted to use of fdisk utility and some other simple systems. Today the use of such solutions even by really well skilled users can cause irreversible consequences.
File systems
The method of storing and spreading the data on the HDD is usually defined by a file system. Free space is separated on several partitions with some logical drives within. Windows can work with different file systems which are named NTFS (NT File System) and FAT (File Allocation Table). FAT is older system that was used in DOS as FAT-16 and in Windows 9x/ME as FAT-32. FAT-32 was developed on the principles of operating of FAT-16 but it can serve more information. The disk space limitation for FAT-16 is only 2 GB. Developers of Windows of the modern versions brought the opportunity for the clients to work with both FAT and NTFS systems.
The basic reason why modern versions of Windows work with NTFS as a primary system is that it has got nicer level of safety. Moreover NTFS allows to define access rights for every single file. Every first sector of every disk contains information that is named disk partition table and boot record which is considered to be service data. If the data in MBR is defective computer won't boot at all and some setors can be described as empty.
Data recovery
When you realized that you have erased some necessary data you need to stop executing any operations with any information to execute hard disk recovery. If you have erased the needed partition and created the new one you shouldn't take any measures at all. If you deleted something which was saved in recycle bin and you understood that you need that information do not add any information on the HDD. If you marked the new partition the data from the deleted one is still on the face of the HDD.
That is considerably harder to restore lost data if there is only one partition on the HDD. In these cases we should utilize another computer to operate with the HDD. Operation with another computer has got many advantages.
Data recovery utilities
Another thing you ought to always remember is you don't need to reinstall the operating system not to lost the information ultimately. You can find lots of useful solutions that may easily start the boot action and boot the other special operating system.
We live in the epoch of commerce so it is possible to get the restore utilities free of charge but it would operate not really efficiently and probability of complete file recovery would be lower. The market is full of great propositions and such type of programs is believed to be cheap.
