Today computer is being an integral and indispensable part in IT world. No matter what is your line, finance, education, business consulting and investigation, IT information security, or else. In fact, most people always take it for granted. You should never brag your computer can be failure-free.
The foremost use of computer is data storage. All the data is stored on a physical disk named hard disk drive which is a magnetic layer. And it is more likely to be stricken of any time by a wide variety of reasons, such as a partition lost, system can not access, human mistake (accidental reformatting, delete), file corruption, power surge, and virus attack, to the worst, these physical level failures typically are head crash, platter scratch, and motor failures caused by overwriting, physical damages, natural disasters, etc.
Sometimes a hard drive has been stricken dead or not working at all without any warning signs, but some other times there may be some clues that something is going bad or amiss. Such changes in performance or sudden blue screens are telltale signs that the hard drive may be on its way to collapse. The most obvious and common sign are clicking, squealing, scraping or grinding noises.
The computer become more involved in our daily life, so the danger of data loss also surfaces.
As most of us have already experienced data loss, it could be frustrated and traumatic, when you finally find your critical data are not able to recover. As a matter of fact, logical failures as I previously mentioned, a data recovery software program can simply work them out, but if more, No! Those drives with minor physical failures will need special equipment to repair hard drive or recover data.
Why data recovery software programs will stop there? The ordinary user-level repeated-read access method that used by imaging software bring a risk of damaging the disk and head, making data lost irretrievable. Also the software skips bad sectors directly in order not to get hang. Even so it gets hang most of the time in case the drive has lost of bad sectors. Still there is no guarantee that all the data will be extracted as much as possible, although days or weeks of time wasted on imaging bad drives. That’s why you should avoid it at all cost.
With a unique data recovery equipment known as Data Compass which is mostly used among experts and practitioners worldwide where traditional tools can not reach the height. DC reads data of each sector physically byte-to-byte, including good and bad, and copied to a good disk using its data extraction software and hardware. A ShadowDisk technology allows DC to maximally avoid second damaging drives.
However, we hardly figure out how much data normally can be recovered. It all depends. In most cases, data will be able to recover as long as the parts of hard drive are not severely damaged. Otherwise you should swap its components then are platters, heads, and a spindle motor.
A current tool HD HPE PRO used to open hard drive will be replaced by HPE SP. The new product is the offspring of the old one; what’s more, a brand new designed platter exchanger allows users to work on hard drives with spacers between platters. HPE SP is made of metal alloy and has had both quality and stability improved. If you have already known about data recovery, you can be an expert with the very option. Of course, you can go and find an expert elsewhere to fix your drives, if the extra expenditure is not a problem anyway.
