The following information describes how clusters and sectors are organized on an NTFS volume, how the boot sector on the volume determines the file system, and how the Master File Table (MFT) organizes structures on the volume.
Clusters and Sectors on an NTFS Volume
A cluster (or allocation unit) is the smallest amount of disk space that can be allocated to hold a file. All file systems used by Windows Server 2003 organize hard disks based on cluster size, which is determined by the number of sectors (units of storage on a hard disk) that the cluster contains. For example,…
A file system is a required part of the operating system that determines how files are named, stored, and organized on a volume. A file system manages files and folders, and the information needed to locate and access these items by local and remote users.
During the format of a volume you can choose the type of file system for the volume. When you choose the NTFS file system, the formatting process places the key NTFS file data structures on the volume, regardless of whether it is a basic volume or dynamic volume.
During format and setup of a…
According to Murphy’s Law of Data Loss, "The probabilities of a hard disk crash increase with the number of days since the drive was last backed up." No hard disk drive is ever completely safe from crashing, and losing all the important data on it.
A disk drive can be damaged due to a number of causes such as virus attack, voltage glitches, software malfunction, hard disk format, accidental file/directory deletion, human error or even sabotage. Such events cause corruption or damage to the disk drive, and make the data completely inaccessible to the user.
Data Recovery comes…
Natural Disasters is the least likely cause of data loss however they can kill an entire company. The eruption of natural disasters and the complete equipment failure are rare but they do occur. Although it accounts for around 3% of all data loss but the magnitude of data loss is highest.
The disaster may strike anywhere and occurs in many shapes and sizes. Natural disasters may occur in the form of fire, flood, lightening strikes followed by power surges.
You can protect your valuable information from getting destroyed by the evil effects of a disaster by following the below-mentioned…
Linux is a great and powerful operating system that has included unique features, advanced technologies and great applications. The reason behind its popularity is its great maintenance and security of data stored into their hard disk. Linux operating system is a multi-user and multi-tasking operating system that is the need of today’s world where unlimited data storage required into the computer. It is very powerful and easy to use operating system that has no required extra efforts. Anyone can use this that has technical sound or not.
Since it has multi-user & multitasking capacities, it is widely used around…
Defining how hard drive manufacturers and operating system interpret megabytes and gigabytes.
Hard Drive Manufacturer Capacity Definitions
The listed capacity is an unformatted (raw) capacity. After partitioning and formatting, actual storage capacities may vary depending on the operating system and configuration. Maxtor adheres to the NIST and IEC definitions of Megabyte and Gigabyte.
Examples:
1 MB = One Million Bytes
1 GB = One Billion Bytes
Operating System & BIOS Capacity Definitions
Storage devices are marketed and sold in terms of decimal (base 10) capacity. In decimal terms, one Gigabyte (GB) is…
Normal mode is the standard BIOS translation scheme. This mode does not support drives greater than 504 MB. Large mode is a generic translation scheme used by some BIOS’s to access drives up to 1 GB. Logical Block Addressing (LBA) mode is a more advanced method of translation than Large mode. LBA mode is a somewhat faster and can see drives 8.4 GB and greater.
How do I perform a Low Level Format on a SCSI disc drive?
- Download and install SeaTools_enterprise software. Use SCSIMax for Maxtor or Quantum SCSI drives.
- Click START | PROGRAMS | SEATOOLS ENTERPRISE to run the program. It will scan any SCSI device(s) installed in the system.
- Highlight the drive you would like to format.
- Click VIEW | ADVANCED. This will take you to the "Advanced Menu" of the software.
- Click ADVANCED | FORMAT. This will bring you to another screen. Click the "Format" tab.
- Click the "Format Now" button.

Why does the data from my old, smaller hard drive take up more space on my new, larger hard drive?
This is a limitation of your operating system, not of your hard drive.
In operating systems using a File Allocation Table ( FAT ) architecture, a "cluster" or "allocation unit" is the smallest unit of storage space required for data written to a drive. There are limitations to how many clusters a hard drive can be broken down into. "Slack space" is the difference in empty bytes of the space that is allocated in clusters minus the actual size…
How can I tell what type of file system (FAT16, FAT32, NTFS) my drive is formatted in?
To identify what type of file system the drive is formatted in:
- Click on the Start button and select Computer if using Windows Vista, My Computer if using Windows XP or 2000, or Windows Explorer if using Windows Me or 98.
- Right-click on the drive letter you want to check.
- Click on the Properties option from the pull down menu. A window will appear with the type of file system you have. If you do not
