How To Recover Data Or Survive A Hard Disk Disaster

A hard disk drive (HDD, or also hard drive) is a fixed data storage device that stores data on a magnetic surface layered onto hard disk platters.
A hard disk uses rigid rotating platters (disks). Each platter has a planar magnetic surface on which digital data may be stored. Information is written to the disk by transmitting an electromagnetic flux through an antenna or read-write head that is very close to a magnetic material, which in turn changes its polarization due to the flux.

The information can be read by a read-write head which senses electrical change as the magnetic fields pass by in close proximity as the platter rotates.

Disk failure occurs when a hard disk drive no longer operates and the information on it can no longer be accessed by the computer.

This can happen for no reason at all or due to an external factor such as exposure to fire or water or High Magneticwaves or suffering a sharp impact
How seriously the disk failure is varies.

The most serious and well-known kind is the head crash where the internal read-and-write head of the device touches a platter or a magnetic data storage surface. A head crash normally causes severe data loss and, moreover, data recovery attempts may cause further damage if not done by somebody with specialized knowledge.

There are also controller electronics which occasionally fail. If that happens it may be possible to recover all data.

When your computer's hard disk starts to act funny, make sure that you have an up-to-date backup. Then you can prepare some simple diagnostics and possibly repairs. Both Windows and Mac OS come with built-in hard-disk utility software that scans your hard disk for errors and attempts to fix them.

This is what you can do for Windows Steps: 1. Double-click on My Computer to open the My Computer window. 2. Select the disk that you want to diagnose and repair. 3. Choose Properties from the File menu. You can see the Properties window for the drive that you selected. 4. Choose the Tools button. 5. Click the Check Now button under Error Checking Status. 6. Choose either "Thorough" or "Scan for and Attempt Recovery of Bad Sectors." 7. Click on Start.

Tools to recover data are various such as:

There is a Data Recovery Utility which examines your inaccessible hard drive for damages and corruptions and recovers the data back.

Hard drive can be recovered from Windows 9x / ME / NT / 2000 XP / 2003 disk recovery
Supports FAT16, FAT32, NTFS, NTFS5 file system
Provides data recovery from Formatted logical drives
Recovers data from Re-partitioned & Missing/ Lost Logical drives
Lost folder and deleted file recovery.

There is also a partition recovery utility available that helps you in recovering all your important data lost after accidental formatting, virus problems, software malfunction,and file or directory deletion. There are also easy to use FAT & NTFS Partition File recovery Utilities that examine your inaccessible hard drives for damages and corruptions and recover the data.

There are also systems which:

Provide Partition recovery from FAT16, FAT32, NTFS, NTFS5 file systems.
Recover deleted files/folders even after recycle bin has been emptied or use of Shift+Del key.
File recovery from deleted partition, lost partition missing partition or formatted logical drives.
File recovery from Missing or Lost folders.
Recognize and preserve long file names when restoring files & folders.
Multi-Disk Drive Support - Performs NTFS recovery on all IDE, EIDE and SCSI disk devices.

There is also software that recovers corrupt or lost data from floppy disks.

The software supports inaccessible floppy disk data retrieval, FAT, BOOT or ROOT area damaged situations, and rescues various corrupt files from a diskette. BadCopy Pro can recover data from floppy disks that Microsoft Windows identifies as "not formatted", "not accessible", or prompts you to format.

The software does not write data to your floppy disks, but saves the recovered data to a new file that you specify.
It can fix corrupted files on floppy disk.
It can restore damage to a FAT (File Allocation Table) or BOOT area of the disk.
It can repair damage to the ROOT area of the disk, so that files can be listed again.
It can erase Viruses on a diskette.

There is also software available that fixes corrupted or damaged Microsoft Word documents.

There is also a new product on the market; software that creates a Windows CD for you, and creates recovery files so you will not need to format to reinstall Windows.

It has been asked many times "I have Windows XP (or ME), how can I install Windows without having to lose all my files. I only have a Recovery Disk". Well it is really very simple, so long as you have a CD burner; or at least a second hard drive.

Is Your PC Crowding Your Desk?

When your PC eats up almost the entire space in your computer table, it’s time to have a little re-organizing. Desktop computers, especially those bulky CPU’s and monitors could eat up quite a space which could be a room for other essentials such as folder stackers, telephone or fax machine. Nowadays, bulky personal computers can be really heavy to the eyes, especially since in today’s technology, the adage, “bulk is out, thin is in” is the mainstream.

Let’s start with your computer table. Its size may vary depending on your design. It may be wide enough to accommodate two “bulky” PC sets, or it could barely hold one, and you don’t have enough space left for the keyboard or the mouse.

First things first, remove all unnecessary files, folders, papers, trash, coffee mugs and saucers, ashtrays, etc. on your desk. Clear the area. Your computer table should be just that, a computer table and not a hodgepodge of everything else. However, top designers say that there are some essential things that should be within reach (especially for an office desk).

The telephone, for one should be within reach. Some very important and frequently used documents could be stacked inside an upright holder which can cover only a little space and is still within reach compared to when just piled up on top of the table.

However, if the area is already clear, but you can still barely fit a small pen holder on top of it, you should think of getting yourself a bigger desk or… a new set of personal computer.

Super space-saving computers have flooded the market nowadays. Try checking out flat monitors to replace your old, bulky one. Have your CPU re-designed or buy one of those small and slim tower CPUs. Small and compact keyboards are also available, reducing the size of a regular keyboard to almost a half.

And, if you do not have a place to slide your mouse in, try using a trackball mouse. That way, it occupies just that small space and you don’t have to glide it across a wider area.

Or have all of those pieces in one super sleek laptop notebook. People on the go prefer to have a laptop which they can take along whenever and wherever they go. And nowadays, laptops are not at all far behind in terms of technical capabilities vis-?-vis PCs.

It is always a good thing to see a clear and organized computer table. It would compel one to work well, without the mess adding up to the already full and cluttered working brain. And, admit it, it’s nice not seeing those bulky gadgets anymore. It helps ease the heaviness in the mind as well.

How To Buy A Printer

A Lot of people tend to just go cheap when buying a printer, but in the long run it can end up costing you more. Even though Ink jet printers might be inexpensive up front the cost of replacement ink can drive up the overall cost over the time of ownership.
You know what I am talking about, some times the ink is more than the printer was.

Check the prices of the ink cartridges of the printer you are considering and find out how many pages each cartridge will print. Once you figure out approximately how many pages you will print per month, you can determine the cost of the printer plus ink over the course of a year. Consider getting individual cartridges if you know you'll need one
color more than others--for instance, if many of your documents have a red logo or if you print mainly black and white.

Manufacturers very often list faster print speed specifications on their packaging than we see when testing performance. A typical ink jet printer can produce two to four pages per minute of text and one full-page, 8.5-by-11-inch photo or graphic in two to three minutes.

Some color ink jets can print photos at a level that approaches the quality of a professional photofinisher. If you plan to use your printer primarily for photos or graphics, look for models that are built for that. If you plan to print mostly
photos, look for photo printers with features such as a built-in PC Card slot, an LCD panel that allows you to view and print an image without using your PC, and bundled image-editing software.

If you print mainly text documents, consider buying an inexpensive black & white laser printer. These printers provide superior text quality compared with high-end ink jet printers. Some monochrome lasers cost as little as $200, making them a good deal for
home users. If you need to print a lot of text and high-quality graphics, buying a good photo ink jet printer in addition to an inexpensive monochrome laser printer could save you money on ink and maintenance costs in the long run as opposed to buying an ink jet to do it all.

Many monochrome lasers come with optional ethernet ports for networks. If you plan to use the printer with one PC, don't pay the extra money for an ethernet card.

Color laser printer toner cartridges are the most expensive consumable you can buy for a printer, but their yield is so much higher than an ink jet cartridge that, in the long run, color laser toner is less expensive on a per page basis.

If you're not running a graphics department but still want to print color, you'll most likely choose an ink jet printer, which can create beautiful graphics at a tenth of the cost of a color laser. However, keep in mind that the inexpensive price of an ink jet is quickly surpassed by the cost of replacement ink.

Overclocking your Processor

Overclocking, which was once the domain of power users and high-end gamers, has now gone mainstream. It’s true that overclocking might prove to be a shot in the arm for your CPU. However, if things go awry, you could well have a fried CPU.

There are scads of information regarding overclocking on the Internet. But sadly, most of the websites tout overclocking as a walk in the park, misleading users by concealing the associated risks. A computer novice, unaware of the risks involved, may set out to overclock the processor based on some advice he got from such a website. This really makes me cringe. Is the whole process of overclocking a no-brainer?

In simple words, overclocking your processor requires an alteration in the hardware settings in order to make it run faster than the manufacturer’s specification. The ideology is that the manufacturer’s ratings are a result of stringent trials and tests performed against the CPU. Then onwards, the CPU is tagged with a particular clock frequency at which it can take up substantial workload on a regular basis without malfunctioning. This clock rate is often a notch lower than the maximum a CPU can sustain.

PC enthusiasts perceive this as a windfall, and try to breach the frequency barriers set by the manufacturers. This can be a viable option for CPUs which can be easily overclocked, since some CPUs have better overclockability than others. But in general, overclocking your processor can be a risk-prone endeavor.

Overclocking is also employed by a few unscrupulous component resellers. They overclock a processor, falsely remark it as a high speed processor, and then onwards sell it at profit. Major brands like Intel strive to curtail such swindling acts. Intel has employed a mechanism called CPU locking, where the clock multiplier is set to a permanent value. Therefore, overclocking your processor, especially if it’s an Intel product, is a bit harder than usual.

A point to be noted is that Intel’s CPU locking mechanism has much to do with unscrupulous vendors rather than end user overclocking. But at the end, it looks like you might have to seek out other means for overclocking your processor.

Let’s say you really want something extra from your existing CPU, but you are on a shoestring budget, and the best possible option is overclocking. Even if you opt for overclocking your processor, you need to take a few precautions, lest it can be a real bummer for you.

The conventional heat sink and CPU fan won’t do much good, since an overclocked processor dissipates a lot more heat. If not dealt with properly, you could face frequent hang ups, system crashes and random reboots. Though a rarity, your processor could also suffer permanent damage. It is recommended that you install an effective cooling mechanism for your overclocked processor, such as water cooling or Peltier cooling. Also ensure that you possess a computer case that enables proper ventilation for an efficacious cooling.

What I have presented here might appear dissenting to a few overclocking zealots, but it’s the truth. I suggest you carry out some basic research before you plan on overclocking your processor.
