How to Recover Needed Data
September 9th, 2008Reading current text you will search out a huge amount of information about hard drive recovery and some procedures performed to save data. No one is proof against the information loss. Even great corporations which spend huge amounts of money on the newest systems frequently ask for help of experts.
In case you are a well-skilled client you ought to realize that HDD is not believed to be a reliable place to save some very necessary information. You need to understand that HDD is a mechanism and any mechanism has got definite operation life and that is not actually big. In case there is a mechanical problem sometimes it is not possible to restore any data as HDD gets completely unworkable.
If you have been working in computers field at least for several years you should remember that one of the most popular programs of info recovery was fdisk. The main disadvantage of use of such program is that it is really hard to use and it can be properly applied just by a programmer.
File systems
The method of storing and spreading the information on the HDD is usually determined by a file system. Free space is divided on some partitions with some logical drives within. Even not quite experienced user can easily say that there are two types of file systems and remembers their codes NTFS (NT File System) and FAT (File Allocation Table). Windows OS of the previous generation and DOS utilized FAT-16. Newer Windows work with FAT-32. FAT-32 was developed on the principles of operating of FAT-16 but it may serve more data. That is difficult to believe that users used FAT-16 and had disks not bigger than 2 GB. In modern versions of Windows the main system is NTFS but it can simply operate with FAT without problems.
Of course all the Windows OS could work with FAT but NTFS offers significantly more possibilities. It has become probable to get access rights for every file with use of NTFS system. Every initial sector of every disk contains information which is named disk partition table and boot record that is considered to be service information. If the information in MBR is defective computer won't boot at all and some partitions may be shown as empty.
Data recovery
If you decided to recover ntfs you oughtn't to execute anything since moment you revealed the loss. Even when you have erased the whole partition you have got the chance to restore it but don't write any information. The identical actions should be performed when you accidentally deleted any significant information from the recycle bin. The data is not deleted, it is still on the disk until you overwrite it with some new information.
There may be some extra problems in case your HDD includes just one partition. But that is possible to solve that complexity by means of usage of another computer. Work with another computer has lots of benefits.
Data recovery utilities
If you don't have a possibility to replace the disk do not be tempted and do not reinstall the operating system. There are some software programs that permit you to boot the computer under the control of the alternative operating system.
We live in the age of commerce so it is possible to find the restore solutions free of charge but it would operate not really efficiently and probability of complete ntfs undelete will be lower. The market is full of great proposals and such type of programs is believed to be inexpensive.
