Well, I'm not very convinced, and here's why. The US Federal Agency, the Pentagon, has put up a live advertisement seeking clarifications on such "machines or technologies" on their website. This advertisement has been up since the 9/11 incident over five years ago. So, how many responses do you think they got?!? Well, a month back, the Pentagon has finally decided to pull the plug on the ad due to the fact that there has not been a single reply for over five years!! Beginning to see the light? I thought so.

So, where do we go from here? In the meantime, true advanced technological developments are being accomplished by the newly established and upcoming hardware industry in India and the Far-East, specifically China. This technology is extremely intricate and requires molecular technologies in addition to advanced materialogy science.

A magnetic disk/platter is made of a circular aluminum disk, which is quite similar in shape to a normal CD or DVD, and has a chrome oxide surface coating with the sole exception of the read/write arm-head parking zone. In fact, the high precision required between disk surfaces and the heads causes them to "stick" to each other due to forces of molecular attraction. In order to prevent this effect, manufacturers often use special laser serrations in the zone of contact between the heads and the platters.

Due to their coating of chrome oxide base (which is a magnetically active substance) or cobalt layer applied using vacuum deposition, these disks demonstrate specific magnetic properties. Such coating is characterized by a robust and firm hardness and a greater wear resistance.

While tall tales and sales myths are circulating among RAID Data Recovery sales representatives in the USA & Western Europe, advanced data recovery technologies have predominantly been emerging from the Far-East, the former Eastern Block countries & India.

Meanwhile, it is expected that there will be an even bigger boom in the new hardware industry constantly developing in mainland China. This is due to a recent announcement that core investment in the hardware manufacturing industry will be tripled.

With Asia showing such strength in developing advanced data recovery technologies, it is but a matter of time when a collective, comprehensive solution data recovery solution emerges. Watch out - companies of the west - you are about to face some stiff competition. Time to change those flawed policies - people!

Server Recovery Experts

HDD repair experts

So, let's assume you have just managed to delete your data somehow. If that is the case, here is something you can do. You could pry open your hard drive …. And …. Hey! Wait up - I'm just kidding! Seriously speaking - Never try to disassemble your drive at any time. It's a no-no. Depending on your situation, there are many options open to you.

If you are an advanced user, you could try many different options. You could try to undelete the data lost or try to repair the damage using simple data recovery tools. If that does not work (and most likely will not), there is a lot of good data recovery software available which you can use depending on your situation. If you need advanced trouble-shooting, you may need to buy more heavy duty software which allows you to work with restoring your hard drive partition table, and more in-depth stuff. Sometimes, if luck goes your way, and the data is recoverable, you may be able to retrieve it on your own.

In case you can't, or you are a novice at data recovery, you can always use another option. By the way, never tinker with your hard drive partitions or boot sectors. You may inadvertently make any data recovery impossible. Coming back to the point, you can always opt for option B. Option B is where those data recovery guys come in. The aim of any data recovery company is to try and recover as much of your data as possible, and to attempt your hard drive(s) to their previous state.

A lot of businesses think that there is little utility for the services of a data recovery company if a proper back-up system is in place. While regular data backups seriously reduce the possibility of data loss, even the best back-up systems can fail. For example, in case of fires or power surges, if your backed-up data is kept onsite, there is a strong possibility that the original data as well as the back-up may be lost.

Calling in a data recovery expert is your best bet after you are unable to recover the data on your own. Many good data recovery companies only charge you if they can get your data back, and will quote accordingly. This is a fair system. If they are good, (and we are assuming they will be) then you should be able to salvage some or all of your data. If even they cannot recover your data for you, then it's probably time for you to kiss your data goodbye. More often than not, the odds are stacked against you when you are in this situation. It's an uphill battle. Consider yourself lucky if you get your data back.

1. It pays to have redundancy

As an administrator or even a user, make sure that you always keep a backed up mirror image of any striped RAID that you use. Keeping a mirrored image will ensure that you have a fall-back in case of data damage or hard disk failure. If you use RAID Level 0, you can do striping which puts smaller fragments of data into different available hard disks and allows you to put them together later. If you have RAID Level 1, you can do striping which backs up your intire system into one or more hard disk drives. Try to backup as regularly as possible - daily would be an ideal situation. That way you will have a ready copy of your data to fall back on.

2. Don't always listen to the system

If the system finds that there is a damaged or faulty hard drive, DO NOT ATTEMPT to reconfigure the RAID even if the system prompts you to do so at any time. Use your own judgement when it comes to handling the system. Once platters are damaged, striping overwritten or changed completely, the chances of getting your data back are slim. Keeping that in mind, try not to reconfigure the system at all. Leave it as it is, and try to sort out the problem through a different route.

3. Never format any HDD

Permanent data loss generally takes place when hard disks have been swapped, switched from one place to another or installed into other computers in a bid to rebuild or repair the array. Formatting a boot drive or partition can also damage or remove striping, which reduces the recoverability of data and causes permanent loss. So, don't try to format the HDD as you may inadvertently manage to erase all chances of recovering you data.

4. Defragment your hard disk drive regularly

It pays to do regular maintenance on your disk drives. This keeps the data stacks in healthy shape, and helps keep the general data distribution in healthy condition.

5. Backup Important data Separately

Make sure you save copies of files regularly used, by creating a "save as" copy of the file on monthly basis. You can then rename this file and save it to a fresh location, and continue to work on the fresh copy to provide maximum protection to your data.

6. Partition Magic

Make sure you create different partitions apart from the one housing the operating system, and try to use the second partition as far as possible. You can do this through your operating systems management console.

7. Always use anti-virus and a firewall

One cannot stress this enough! Get them both installed and leave them there. Update them both regularly to ensure that you do not have any external attacks on your system! This is a must!

8. Backup using good software

This is a very basic step, and should be done as soon as you get a chance to do so. You should always back up your data, and there is plenty of backup software available that helps create an image of the drive, which can be used in case of any damage.
