Beginners Guides: Recovering data from disk part 1

Hard Drive Data Recovery

Get a hard drive problem

If you are using your computer at the time a good chance that someone tells you that the information stored on a hard disk is very uncertain. I'm here, that this is true.

Do not worry that, in contrast to, or CD-ROMs or other methods of storage, hard drives are mechanical devices and active break relatively quickly.

No, the real threat to the hard drives of people who use them, can you tell me, and me. Hard drives, storage media are dynamic, it is very easy to cancel at any time the amount of fun and easy to do ..Recovery and USB hard drives and flash memory cards (advice to the media in detail here.)


The technical team glory days of Windows 98, more accustomed to leading with FDISK and other disk utilities for the manufacture and repair of the customer's computer, the self-satisfaction. Who can jump to the nature of the disaster, as a child of 12 years, the SUV keys.

Imagine, if you wish I was there two or three sentences and a screenshot, or 5000 + word article for the modernization of the equipment. Everything I needed to do was to fdisk dual boot Windows98/XP Pro and screenshots. I had to write a little blurb about the partition, so readers should be advised not to confuse with FDISK, when they know not what they doYes, there is a certain irony.

But I wanted pictures of sections of the screen, get more, but it is blank hard drive. I use XP with NTFS formatted disk (Fdisk is seen as a blank made) to the process "open", screen shots, and then remove the Partition Manager.

It's nothing. Except for one small thing
I forgot that the verification procedure to return the disk and fdisk the entire partition, enter the information in some of the disc. These data, wrote about what could have been before. But I did not want to see in "and I wonder why the little red flags on my brain go on?" I restarted WinXP and I waited and waited and waited ..and ..Oops.

Regress

Primary Partition Gone?

Hard drive has suffered the loss of data 17 GB Fujitsu hard drive two NTFS partitions, 5GB XP (Home and Professional) and 6 GB of free disk space. Both are XP partition, beginning after the accident.

After you move the device to use Windows 2000 Disk Manager (Download Disk Manager 2000 or XP, right-click My Computer, choose Manage, and then Disc Manager), which is what I have seen.

Section, which is stored on my 5000 + word article normally, and can not be seen as operating system. Second partition of XP can not be used, but it seems that the shape, and I could transfer files via the browser. Unfortunately, all the necessary information for the first partition.

What to do? Well, there are some tricks you can get data on the brink of what I created for myself here. But we must first understand what file system and how to regulate access to computer data.

Filesystem Overview

File System is a method of the operating system to organize data and the free space on your hard drive or other storage device, that read and write. File systems create areas of free space on partitions that are processed and the file system as a logical drive (C: D: read, etc.) and write.

Two files are used by various operating systems, Windows NTFS (NT File System) and FAT (File Allocation Table). FAT is larger, because for the first time in DOS FAT-16, and then Windows 9x/ME as FAT-32.

Only significant differences between the FAT-16 and -32 is the amount of data that can be processed. FAT-16 up to 2 GB of storage for each logical drive can be FAT-32 has not been used for this restriction. Later Microsoft operating systems like Windows 2000 and XP are fully compatible with the FAT system, but not used by default to save files.

NTFS in Windows NT, 2000 and XP and offers a file storage used safely and efficiently. In addition, the security is implemented in the individual files, NTFS also store backup data to disk in the fight against the disaster recovery.

Both file systems use Master Boot Record (MBR) and partition table, which is the first sector of each hard disk or a disk. MBR and partition table what partition (s) is a bootable CD search, and and the transfer of control of the operating system partition.

If the partition table or MBR is damaged, start the machine and can not seem empty, when the partition is removed .
