Experts mention that HDD is not really the best way to store quite necessary info as there is a probability that it would be lost soon. Unlike CDs and other types of data carriers HDD is a mechanism which wears out as any other mechanical system. If there is a mechanical failure sometimes it is impossible to restore any information as HDD becomes completely invalid.

Several years ago there was a really popular software solution that assisted to restore some data. It was actually often utilized and was called fdisk. The basic drawback of usage of this program is that it is really hard to utilize and it can be appropriately applied just by a programmer.

File systems

File system determines the method that is utilized to save data on the face of the HDD. Every HDD is divided on some sectors. These sections are named partitions. The most widespread file systems that are used by Windows are NTFS (NT File System) and FAT (File Allocation Table). FAT is older system which was utilized in DOS as FAT-16 and in Windows 9x/ME as FAT-32. If we compare these two systems we can find that FAT-32 can operate with bigger volumes of data. It is hard to believe that users utilized FAT-16 and had disks not greater than 2 GB. Developers of Windows of the newest versions gave the opportunity for the clients to operate with both FAT and NTFS systems.

Of course all the Windows OS can operate with FAT but NTFS offers considerably more abilities. That has become possible to get access rights for every file with use of NTFS system. All these systems utilize disk partition table and boot record that are stored in the first sector of every disk and determine which one is boot disk. The loss of that info can cause many serious problems as the computer won't boot properly and some data can be lost.

Data recovery

When you understood that you have erased some necessary data you have to stop performing any actions with any data to execute partition recovery. Even when you have lost the entire partition you have got the chance to restore it but don't write any data. In case you deleted something which was saved in recycle bin and you realized that you need that data do not add any information on the HDD. In case you created the new partition the information from the erased one is still on the face of the disk.

The most uncomfortable case is when your HDD has got just one partition. You need to find the other computer and connect your disk to it then. Work with another computer has lots of benefits.

Data recovery utilities

In case you haven't got a possibility to replace the HDD do not be tempted and do not install new operating system. There are several software programs that permit you to boot the computer under the control of the some special operating system.

We live in the age of commerce so that is possible to get the restore solutions free of charge but it would work not really efficiently and probability of complete ntfs undelete would be lower. The market is full of great propositions and such type of programs is considered to be inexpensive.
