What is partition?

To divide memory or mass storage into isolated sections. In DOS systems, you can partition a disk, and each partition will behave like a separate disk drive. Partitioning is particularly useful if you run more than one operating system. For example, you might reserve one partition for Windows and another for UNIX.

In addition, partitioning on DOS and Windows machines can improve disk efficiency. This is because the FAT system used by these operating systems automatically assigns cluster size based on the disk size: the larger the disk, the larger the cluster. Unfortunately, large clusters can result in a wasted disk space, called slack space. There is an entire sector of the software industry devoted to building utilities that let you partition your hard disk, such as Fdisk, Partition Magic, Partition Manager.

Explanation

The Fdisk commands are typically run to prepare a new hard disk for use - enabling the division of hard drive and the installation of an operating system, application programs & eventual user data. The Fdisk command has been around for a long time, formerly they were stand alone DOS programs before being integrated into Windows.

Symptoms

Where previously the computer would boot and be usable, systems that have been Fdisked often report the following errors: (these errors are frequently displayed on a black screen with white text)

• No boot device
• Operating System not found
• Primary Hard Disk not found. Press F1 to Continue
• Master Boot Record Not Found
• Invalid or corrupt FAT
• Invalid partition table entries
• Invalid sector
• Cannot find file or program
• Invalid command.com
• Primary/Secondary Hard disk failure
• Non system disk
• Disk error

To recover files from a Fdisked drive, follow these steps:

First We recommend that you use professional partition recovery tool - Partition Table Doctor to recover missing or lost partition.

If Partition Table Doctor cannot help you, you can use Data Recovery Wizard to recover files:

1. Click the "Partition Recovery" button on the main interface of Data Recovery Wizard.

2. You can see the list of all physical device(s).

3. Choose one hard disk and press "NEXT" button.

4. Then, the Data Recovery Wizard will do a Quick Partition Searching.

5. When the Quick Partition Searching is complete, you will see a list of volumes. Please choose one of volume and press "NEXT" button (if you are familiar with file system details, you can change "Option" before pressing the "NEXT" button).

6. If the volume is not listed here, please tick the "Full Scan (If the partition is not found, please check it and click NEXT)" to scan the device again.

7. You will see the Intelligent Searching for searching in detail.

8. And then, you will see the Select Recognized Partition Page. Please select one or more partitions with the file systems which you are sure or unsure.

9. The Data Recovery Wizard will enter Building directories interface to find files.

10. After this scanning is finished, you'll see file/folder tree.

11. Select the file(s) or folder(s) that you want to recover and press the "NEXT" button.

12. Select a directory and press the "NEXT" button to save the data.

Please see "Partition Recovery" for more details.

The demo version of Data Recovery Wizard gives you a much fairer idea about chances of data recovery from your hard disk before deciding upon the purchase. You can buy full version to recover data!

Caution: Saving file(s) to the partition or drive from where you are recovering data, for it may result in overwriting of data, and would result in permanent data loss!!!
