<h1>How To Recover Data Or Survive A Hard Disk Disaster</h1><p> <br /><br /><br /> A hard disk drive (HDD, or also hard drive) is a fixed data<br /><br /><br /> storage device that stores data on a magnetic surface layered<br /><br /><br /> onto hard disk platters. A hard disk uses rigid rotating<br /><br /><br /> platters (disks). Each platter has a planar magnetic surface on<br /><br /><br /> which digital data may be stored. Information is written to the<br /><br /><br /> disk by transmitting an electromagnetic flux through an antenna<br /><br /><br /> or read-write head that is very close to a magnetic material,<br /><br /><br /> which in turn changes its polarization due to the flux.<br /><br /><br /> <br /><br /><br /> The information can be read by a read-write head which senses<br /><br /><br /> electrical change as the magnetic fields pass by in close<br /><br /><br /> proximity as the platter rotates.<br /><br /><br /> <br /><br /><br /> Disk failure occurs when a hard disk drive no longer operates<br /><br /><br /> and the information on it can no longer be accessed by the<br /><br /><br /> computer.<br /><br /><br /> <br /><br /><br /> This can happen for no reason at all or due to an external<br /><br /><br /> factor such as exposure to fire or water or High Magneticwaves<br /><br /><br /> or suffering a sharp impact How seriously the disk failure is<br /><br /><br /> varies. <br /><br /><br /> <br /><br /><br /> The most serious and well-known kind is the head crash where the<br /><br /><br /> internal read-and-write head of the device touches a platter or<br /><br /><br /> a magnetic data storage surface. A head crash normally causes<br /><br /><br /> severe data loss and, moreover, data recovery attempts may cause<br /><br /><br /> further damage if not done by somebody with specialized<br /><br /><br /> knowledge.<br /><br /><br /> <br /><br /><br /> There are also controller electronics which occasionally fail.<br /><br /><br /> If that happens it may be possible to recover all data.<br /><br /><br /> <br /><br /><br /> When your computer's hard disk starts to act funny, make sure<br /><br /><br /> that you have an up-to-date backup. Then you can prepare some<br /><br /><br /> simple diagnostics and possibly repairs. Both Windows and Mac OS<br /><br /><br /> come with built-in hard-disk utility software that scans your<br /><br /><br /> hard disk for errors and attempts to fix them. <br /><br /><br /> <br /><br /><br /> This is what you can do for Windows Steps: 1. Double-click on My<br /><br /><br /> Computer to open the My Computer window. 2. Select the disk that<br /><br /><br /> you want to diagnose and repair. 3. Choose Properties from the<br /><br /><br /> File menu. You can see the Properties window for the drive that<br /><br /><br /> you selected. 4. Choose the Tools button. 5. Click the Check Now<br /><br /><br /> button under Error Checking Status. 6. Choose either "Thorough"<br /><br /><br /> or "Scan for and Attempt Recovery of Bad Sectors." 7. Click on<br /><br /><br /> Start. <br /><br /><br /> <br /><br /><br /> Tools to recover data are various such as:<br /><br /><br /> <br /><br /><br /> <br /><br /><br /> <br /><br /><br /> There is a Data Recovery Utility which examines your<br /><br /><br /> inaccessible hard drive for damages and corruptions and recovers<br /><br /><br /> the data back.<br /><br /><br /> <br /><br /><br /> Hard drive can be recovered from Windows 9x / ME / NT / 2000 XP<br /><br /><br /> / 2003 disk recovery Supports FAT16, FAT32, NTFS, NTFS5 file<br /><br /><br /> system Provides data recovery from Formatted logical drives<br /><br /><br /> Recovers data from Re-partitioned & Missing/ Lost Logical drives<br /><br /><br /> Lost folder and deleted file recovery.<br /><br /><br /> <br /><br /><br /> There is also a partition recovery utility available that helps<br /><br /><br /> you in recovering all your important data lost after accidental<br /><br /><br /> formatting, virus problems, software malfunction,and file or<br /><br /><br /> directory deletion.

It can fix<br /><br /><br /> corrupted files on floppy disk. It can restore damage to a FAT<br /><br /><br /> (File Allocation Table) or BOOT area of the disk. It can repair<br /><br /><br /> damage to the ROOT area of the disk, so that files can be listed<br /><br /><br /> again.

I only<br /><br /><br /> have a Recovery Disk".
