RAID is acronym for Redundant Array of Independent Disks, also known as Redundant Array of Inexpensive Disks. It is use to increase reliability. You combine multiple physical hard disks into groups (arrays) that work as a single logical disk i.e. this array of drives appears to the computer as a single logical storage unit or drive.

RAID level 5 has following features:

Long file names and directory entries
One last thing to keep in mind about long file names is that sometimes two directory entries aren't sufficient to store the long file name. For example, the name of the file we are working on right now is Data Recovery and Long File Names.doc. If we were saving this file to a FAT or to a FAT-32 volume, the file's...

To maintain this backward compatibility, files that use long file names make use of a DOS alias -- an alternate file name that fully conforms to DOS naming conventions. This is necessary not only because of the length of the filename, but also because long file names make use of characters that are not normally allowed by the FAT or FAT-32 file systems.

Because of these limitations,...

Calculating disk cluster size: A shortcut
If you're having trouble calculating cluster size, here's a shortcut. If you run CHKDSK against the volume that you are trying to recover (don't use the /F switch), one of the pieces of information that CHKDSK will give you is the number of bytes in each allocation unit. An allocation unit and a cluster are t...

Granted, hardly anyone uses the FAT file system any more because it limits you to using a 2 GB partition, which, by today's standards, is ridiculously small. But we wanted to demonstrate the cluster size concept with the FAT file system because the numbers are small, which makes the math easier.

The same concept applies to the FAT-32 file system; the only difference is that the FAT-...

How disk cluster size affects data recovery processes

Now that you understand the basics of performing a simple file recovery using EASEUS Data Recovery Wizard 4.0.1, the next step is to understand how disk cluster size affects data recovery.

But before we talk about disk clusters, we want to mention that the Data Recovery Wizard tr...

Now let's talk about the recovery process. Often when someone erases a file that they really need to get back, the first thing they do is install a data recovery utility. Bad idea! Remember, the deleted file still exists on your hard drive, but the operating system has flagged the space occupied by the file as being available. This means that if files are written to the hard disk (such as occur...

TAG: Data Recovery,windows,data recovery,techniques

If a file physically damaged, your only hope of recovering it (without a backup) is to reconstruct the file. Many applications, such as Microsoft Office, place uniform headers at the beginning of files to designate that the file belongs to that application. Some utilities can be used to manually reconstruct file headers so that at least a portion of the file can be recovered.

In man...

2. NTFS Files: $MFT (0)
2.1. Overview
In NTFS, everything on disk is a file. Even the metadata is stored as a set of files. The Master File Table (MFT) is an index of every file on the volume. For each file, the MFT keeps a set of records called attributes and each attribute stores a different type of information.
