NTFS is an advanced disk formatting that has many useful features including ways to recover lost data. They can be disks of any size and any manufacturer, there is no difference: the NTFS Recovery application will do just fine! You can accidentally delete any system file, and this will be a fatal mistake for you and the NTFS file system.

A virus may mercilessly damage system files. There are a lot of options for dealing with these kinds of events, but here is how to perform NTFS file recovery: use special professional software. This software supports all versions of Windows and recovers files of absolutely any type and size. With this software, you will quickly and accurately perform NTFS file recovery. It can handle type of issue and has everything you need!

How to recover data for NTFS file systems? The recovery process is fully automated and fool-proof. For example the program won't let you further damage your data by restoring your files onto the same disk volume. Windows Vist and newer Windows versions have completely different set of boot system files.

If these files have been deleted, corrupted, damaged by virus, Windows will be unable to boot. So, the next step in recovery process is to check the existence and safety of system files for sure, you won't able to check them all, but you must check at least NTLDR,ntdetect.

This disk is recommended to create after you install and customize Windows. To create it, use the "Backup" utility from System Tools. If you do not have an ERD, the emergency repair process can attempt to locate your Windows installation and start repairing your system, but it may not be able to do so.

To run the process, boot from Windows bootable disks or CD, and choose Repair option when system suggests you to proceed with installation or repairing. Fast Repair is recommended for most users, Manual Repair — for Administrators and advanced users only. If the emergency repair process is successful, your computer will automatically restart and you should have a working system. You can list and display folder content, copy, delete, replace files, format drives and perform many other administrative tasks.

To run Recovery Console, boot from Windows bootable disks or CD and choose Repair option, when system suggests you to proceed with installation or repairing and then press C to run Recovery Console. You will be asked to which system you want to log on to and then for Administrator's password, and after you logged on — you can display drive's contents, check the existence and safety of critical files and, for example, copy them back if they have been accidentally deleted.

Third party recovery software in most cases does not allow you to deal with system files due to the risk of further damage to the system, however you can use it to check for the existence and safety of these files. File recovery process can be briefly described as drive or folder scanning to find deleted entries in Master File Table MFT then for the particular deleted entry, defining clusters chain to be recovered and then copying contents of these clusters to the newly created file.

Different file systems maintain their own specific logical data structures, however basically each file system:. After finding out the proper file entry and assembling set of clusters, composing the file, read and copy these clusters to another location. First , we assume that the file entry still exists not overwritten with other data. The less the files have been created on the drive where the deleted file was resided, the more chances that space for the deleted file entry has not been used for other entries.

Second , we assume that the file entry is more or less safe to point to the proper place where file clusters are located. In some cases it has been noticed in Windows XP, on large FAT32 volumes operating system damages file entries right after deletion so that the first data cluster becomes invalid and further entry restoration is not possible. Third , we assume that the file data clusters are safe not overwritten with other data. The less the write operations have been performed on the drive where deleted file was resided, the more chances that the space occupied by data clusters of the deleted file has not been used for other data storage.

Even file recovery software installation could spoil your sensitive data. If the data is really important to you and you do not have another logical drive to install software to, take the whole hard drive out of the computer and plug it into another computer where data recovery software has been already installed or use recovery software that does not require installation, for example recovery software which is capable to run from bootable floppy.

It's better to save data onto another logical, removable, network or floppy drive. The goal is to find and display deleted entries. Given that a drive contains root file table and any file table MFT, root folder of the drive, regular folder, or even deleted folder has location, size and predefined structure, we can scan it from the beginning to the end checking each entry, if it's deleted or not and then display information for all found deleted entries.

Deleted entries are marked differently depending on the file system. On NTFS deleted entry has a special attribute in file header that points whether the file has been deleted or not. Thus we can iterate through all MFT records, starting from the absolute offset 0x on the volume looking for the deleted entries. MFT Record has pre-defined structure.

It has a set of attributes defining any file of folder parameters. The most important information for us in this block is a file state: deleted or in-use.

If Flags in red color field has bit 1 set, it means that file is in-use. In our example it is zero, i. Following standard attribute header, we have File Name Attribute belonging to DOS name space, short file names, third bold section, offset 0xA8 and again following standard attribute header, we have File Name Attribute belonging to Win32 name space, long file names, third bold section, offset 0x :.

In our case from this section we can extract file name, "My Presentation. To define clusters chain we need to scan drive, going through one by one all file NTFS clusters belonging presumably to the file until we reach the file size equals to the total size of the selected clusters. If the file is fragmented, clusters chain will be composed of several extents in case of NTFS.

Location of these clusters can vary depending on file system. Disassembling data runs to "extents" for each extent we have start cluster offset and number of clusters in extent, so enumerating extents, we can compose file's cluster chain.

Data Runs need to be decrypted. First byte 0x31 shows how many bytes are allocated for the length of the run 0x1 in our case and for the first cluster offset 0x3 in our case. Next, we take one byte 0x6E that points to the length of the run.

Next, we pick up 3 bytes pointing to the start cluster offset 0xEBC Changing bytes order we get first cluster of the file equals 0x04C4EB. Starting from this cluster we need to pick up clusters equals 0x6E. Next byte 0x00 tells us that no more data runs exist. Our file is not fragmented, so we have the only one data run. It also aims to provide an easy way to do administrative tasks on your computer, such as creating and editing the partitions of the hard disk.

It contains a lot of system utilities parted, fsarchiver, file system tools, … and basic ones editors, midnight commander, network tools. It aims to be very easy to use: just boot from the boot media, and you can do everything. The kernel of the system supports most important file systems ext3, ext4, xfs, btrfs, reiserfs, vfat, ntfs, iso , and network ones samba and nfs.

Site map Homepage. It is possible to make custom versions of the system. For example, you can add your own scripts, make an automatic restoration of the system. Read the manual for more details. You can use SystemRescue to backup data from an unbootable Windows computer , if you want to backup the data stored on a Windows computer that cannot boot any more.

You just have to copy several files to the stick and run syslinux.
