Hard Drive Recovery
When a hard drive dies, and a user gets the dreaded blinking cursor, it can really bring about some nightmarish visions. This is especially true if you happen to be sitting on a terabyte or more of important documents, photographs, music, movies, or more. The potential consequences of a hard drive failure can range from simply annoying to serious personal, professional, and financial hardship. Luckily, hard drive recovery is certainly possible under many circumstances. In some cases, it can be as simple as downloading a free utility and spending thirty minutes to an hour. In the worst cases, it can involve shipping a drive off to a professional hardware restoration service.
When the screen comes up with that blinking cursor, it means that the section of the hard drive that stores the operating system is no longer available to the computer. This can be due to a number of possible reasons. In the best case, it simply means that the data in that section has been corrupted, causing the operating system to fail, but otherwise leaving important information untouched. In the worst case, the blinking cursor can mean that the hard drive hardware has failed, and the disk simply does not respond at all. In either case, however, hard drive recovery is a possibility.
Hard drive recovery in software failure circumstances may be very simple. When data becomes corrupt, it can take just a few bad bits to bring a system to a complete halt. This does not necessarily mean that the hardware has become faulty, or that the data is unrecoverable. 99% of the hard drive can be in perfect condition, but if the wrong 1% is affected, nothing will work anymore. Fortunately, this kind of problem is usually easy to reverse. If the hard drive spins up on start and sounds normal, this is a likely candidate. Remove the drive and connect it to another computer, allowing that computer’s drive to boot the system.
Download a utility such as the free and open source TestDisk, and browse to the bad hard drive. The utility will scan the disk and let you know what the problem is. Once the problem has been diagnosed, TestDisk can usually correct any such software related issue. This includes the loss of partitions, and accidental formatting.
Hardware failures are a tougher situation to handle. If a drive sounds erratic, or makes a scratching sound, immediately turn off the system. These are symptoms of a hardware failure, and continued operation under these circumstances can result in further data loss. In cases like this, you may have no other for hard drive recovery than to ship the bad disk off to a service such as DriveSavers. DriveSavers can usually recover data from even badly damaged disks, but their services are costly.
