Having read this text you will find a great deal of information about data recovery and some actions executed to save data. No one is immune against the data loss. Even great corporations which spend huge amounts of money on modern systems frequently ask for assistance of experts. In case you asked for assistance of some expert he would say that it is not reasonable to save all the significant information only on the HDD as that is simply to lose it. You have to understand that HDD is a mechanism and any mechanism has some operation life and it is not really big. But not just the mechanical failures can be the cause of such problems as there are also electronic errors. The programmers who attempted to work out any HDD problems with Windows 98 or earlier systems preferred usage of fdisk utility and some other primitive systems. Today that is utilized only in rare cases and only by real professionals because rookie may make harm to data with it. File systems File system determines the method that is used to save data on the face of the HDD. Every HDD is separated on some sectors. These sectors are called partitions. Even not very experienced user can easily say that there are two types of file systems and knows their names 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. The basic difference between these systems is the potential of the system. The disk size limitation for FAT-16 is only 2 GB. In modern versions of Windows the main system is NTFS but it can easily operate with FAT without problems. The main reason why new versions of Windows operate with NTFS as a main system is that it has higher level of safety. Moreover NTFS allows to define access rights for any single file. The most significant part of information for the OS is the boot record and disk partition table that are placed in the first sector of any disk. The loss of that data can cause many serious troubles as the computer won’t boot properly and some information may be lost. Data recovery The main rule you should never depart from is not to overwrite the lost data if you are going to execute partition recovery. Even when you have lost the entire partition you have the opportunity to restore it but don’t write any information. In case you deleted something that was saved in recycle bin and you realized that you need that information do not add any information on the HDD. If you marked the new partition the data from the erased one is still on the face of the HDD. That is considerably harder to restore lost data if there is just one partition on the disk. You have to look for the other computer and connect your disk to it then. That is more comfortable to operate the HDD form other computer. Data recovery utilities The other thing you ought to always mention is you don’t have to reinstall the operating system not to lost the information completely. There are several software solutions which allow you to boot the computer with the control of the some special operating system. There are many freeware solutions but commonly they are not as efficient as shareware recovery software. Developers of restore solutions understand that data really has got the great price.
