External Drives Data Recovery
A wide variety of failures can propel severe external or physical damage to drives and storage media. When the drive is physically damaged, a greater level of precaution needs to be exercised in order to ensure that the data is still recoverable. To clarify your understanding, external hard drive data recovery means the process of recovering data from external hard drives like USB or Fire wire when the data is neither lost nor inaccessible because of some reason or the other. External hard drive data recovery process comprises the same process followed while trying to recover some lost files. Let's take the example of the ICD-ROMs which may get damaged because their metallic substrate is scratched. Keep in mind that hard disks can suffer any of several mechanical failures, such as head crashes. There can be a case of failed motors so physical damage always causes at least some minimal case of data loss. Most physical damaged drives cannot be repaired by the end users. For example, opening a hard disk in a normal environment is a complete no-no because the dust would obviously settle on the surface. If that happens, that could worsen the damage caused to the platters and complicate the external drive data recovery process even further. The difficulty is that most users aren't experts nor do they have the hardware or technical expertise required to make these repairs. So it is best to opt for data recovery companies to do the job rather than make costlier mistakes that complicate data recovery processes further. Most professionals use Class 100 clean room facilities to protect the media while repairs are being made. How this is done is discussed herein.
The extracted raw image is used to reconstruct data that can be used after any repair of the logical damage is carried out. Once the repair is complete, the files may be in usable form although its actual recovery may turn out to be very incomplete. Some helpful examples of physical recovery procedures include removing a damaged PCB (printed circuit board) and replacing it with a matching PCB from a healthy drive. Other good examples comprise changing the original damaged read/write head assembly with matching parts from a healthy drive, removing the hard disk platters from the original damaged drive and installing them into a drive that works fine. As these procedures are technical in nature, it is best that these are taken care of by professionals and not by untrained persons. When the hard drive is physically damaged, remember that any additional access to the same drive would definitely corrupt data. This would make it much more difficult to get information back. Note that if the damaged drive happens to be the drive containing the operating system, don't consider trying to boot the drive. But for a desktop, there is less cause for worry as all you must do is disconnect the boot drive and replace it with a new drive. A tip for you is that do ensure the drive can accommodate the image of the current drive.
Next, an operating system can be easily installed on the new drive. You just need to reconnect the old drive or put it in an external case and connect via USB or FireWire. In creating a new primary drive, you would be able to run the disk imaging software from the new drive. This way, you would be able to prevent the need for any writing to the old drive. If your hard drive works in a RAID system, you need a service that specializes in RAID data recovery as it wont be a good idea to do it on your own. When a hard drive is prepared for its initial use, the drive is magnetized. This is done with a number of self-synchronizing magnetic bits. The purpose of this self-synchronizing structure is that, no matter where the hard disk is in its rotation cycle, the hard drive controller would be able to speedily touch down as to which of these bits represent no-man's land, which of these actually represent the drive's formatting, and which represent critical data. Various situation based examples were discussed to clarify your queries on external data drive recovery. So do utilize this informative discussion sometime when you come across data problems on your external hard drive.

The world of data recovery is somewhat a big mystery for most consumers and even for some IT professionals. This is largely because hard drives are complex devices and their technological specifics are not generally well known. No wonder, the market for data recovery services and professionals spanned a stunning, astounding figure of over US$100 million. This reflects how rapidly the industry for data recovery services and professionals has grown by leaps and bounds. Let's first understand what brings about data loss. Data loss can be caused by a combination of factors which often requires professional assistance. The current finding of cloning the damaged, malfunctioning drive and using the cloned version on a new drive as a means to recover data may be helpful but it is best to engage professionals to help you. Coming back to our discussion on causes of data loss, this may also occur if your OS fails to boot or if you get a blue screen error, but this should not give an impression to you that all is lost. These data losses can be caused by bad sectors which stall the drive head every time it tries to read them. If your drive is detected by another computer, there is hope of copying your data prior to total failure. There can be situations where you have a brand new hard drive but you still suffered data loss. Sometimes a faulty component or a faulty installation can also lead to data loss. Sometimes it can be due to sudden electric failure to which the brand new hard drive may not be immune. So there are countless causes that can lead to data loss. One of the most often asked questions that you would naturally want to ask if you have suffered a loss of data is, "how can you help me to retrieve or recover my lost data?" Do not worry. With the right blend of knowledge, experience and tools, it is possible for a competent data recovery professional to carry out a recovery 'surgery' for your data loss problem. The data recovery services and professionals are extremely well equipped with an amazing array of software, hardware and other technologically advanced tools to help recovery data. Most of the data recovery labs utilize a combination of the best and most high quality proprietary software, specialized hardware, and years of valuable experience to recover data after a major crash, or even acts of sabotage. There are also highly trained computer forensic specialists who are competent to handle each recovery to ensure your data will not be compromised during the process of the recovery. Most data recovery professionals are extremely conscious of the fact that your data is sacred and irreplaceable to you, so they handle the issue with great care. The first thing that a data recovery firm would do on receiving a hard drive is evaluate it. They would try to see whether logical recovery is required or not. Most firms of repute do not charge evaluation fees but some firms do so and there are other firms that levy an additional charge of on site support. Perhaps these contradictions simply mirror the highly saturated nature of the booming data recovery industry where it seems to be a dog-eat-dog world. The time frame for data recovery comprises about 5-10 business days for physical issues and 2-4 days for logical issues. In situations where the components are not available, this may extend to several weeks to complete the recovery. The costs associated with data recovery services and professionals vary to a great extent. There would be quotes that range from $300 to $5,000 for standard hard drive recoveries. So before you send your drive for data recovery to any professional or firm, make sure that you locate a company that will give you an up front cost, be it for either a logical or physical recovery. In most cases, you will be able to recover your data through data recovery services and professionals. Go ahead and show your confidence and engage data recovery services and professionals to do their job and ease your tensions!

iPod Data Recovery
There is a lot of bad news nowadays because data is getting lost faster than eve before. This has now become a matter of grave concern because large companies are fighting each other to make profits yet their functioning is getting their profit lines into deep trouble. A large part of our work depends on data stored in computers, laptops and even iPods. The iPod is a great device that revolutionized the music industry. Apple's sleek digital audio device is one of the world's most successful tech gadgets that crossed whopping sales of more than 3 million units since the year 2001. By making the iPod so tremendously user-friendly, this device has more a customer base of millions and millions of consumers from all over the world. The iPod makes it legal for consumers to access legal music on demand for just a dollar for every song. This means you don't have to go to the store to buy a CD for $15. You can listen to it on your iPod. This is how the iPod became a household name. But from a security perspective, the iPod hasn't created a good impression at all. Thus, the future of iPods doesn't look too bright. Most gadgets like the iPod, when used by professionals, pose serious and severe risks in the context of organizational security and data loss. Thus, it is now an established fact that when gadgets such as iPods are connected to a work PC, this can be extremely risky. A malicious code can easily enter the corporate network and remain undetected by the intrusion detection software or the corporate network's firewall system. Another danger is that the iPod can work as a USB mass storage device and can serve the same role as a USB pen drive so it does have an impact on computer security though Apple never had that in mind. Controlling the access to iPod data and resources is thus essential. There are methods and mechanisms can be used to accomplish this type of access control, but historically they're generally software-only solutions. But most of these are trapped in evolving phases which makes it difficult to attempt iPod data recovery without the help of professionals. Further, most access control mechanisms relating to iPod data recovery seems vulnerable to software bugs and implementation errors. As this may result in data compromise, it is not worth pursuing. In 1971, a paper titled 'Protection' was presented by Butler Lampson where he explained the concept of data protection through the concept of multiple domains of information running on a single host. This idea is mainly that each domain would execute independently and with differing rights that exist for the programs in each of the domains. This great theory was a huge and tremendous inspiration for countless computer scientists who were researching on the subject. This becomes even more significant in the light of the fact that for content providers such as record companies, this idea from Lampson will allow them to ensure that their content is accessed only in a manner of which they approve. For instance, when we refer to a system like the iPod that has these domains implemented, then the files can be read only by trusted and authorized programs. The problem with this protection theory is that it is not always possible to achieve complete control of data with software-only solutions. Most access control mechanisms fall prey to loopholes that severely damage data later on. Another reason is that access control mechanisms can't be manipulated beyond a point as these are so complicated that they require interaction with the user very frequently. No doubt, the iPod is not an entertainment device any longer. In fact, it is a device that can leak information and store information so handle iPod with care and in case of data loss, get help from the experts.
