While flash drives are more and more widely used by people today,  flash data recovery becomes more obvious and important!  Flash memory devices are very vulnerable to all sorts of environmental influence. Water, humidity, dust, extreme temperatures could be fatal. Flash data recovery becomes more and more important and better flash data recovery tools are required in the market.

If you’re storing important information about your job, or valuable copyrighted files if you are a creative person, many USB flash drives offer encryption features that will be able to protect your files from prying eyes. This is not a standard feature among USB flash drives, but they are available, and that can be invaluable to someone who might leave their drive on a busy train, or in a locker somewhere.

Physically speaking, USB flash drives are extremely robust. Without moving parts, and being so light, most flash drives can withstand being jostled around, dropped, or stepped on without sustaining internal damage. Most also come in a sturdy, rugged encasement that can withstand plenty of roughhousing.

Flash data recovery from USB flash hard drives

USB flash disk drive does not work as expected, it is no longer seen connected under Windows XP/Vista, Mac or BIOS, it doesn’t show up in Device manager and Found new hardware wizard doesn’t pop up or it can’t find standard USB mass storage device driver. Also after inserting faulty USB stick you could get “Usb device not recognized” message in Windows.

Also Windows could give an error saying that USB Device has malfunctioned and therefore cannot recognize the device. Sometimes the device itself might be seen but no partitions or volumes could be found. Or partition might be present but user gets an error when trying to access this volume. File system might also be recognized as “unknown”, “raw” and be 0 bytes in size. You might get “The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility” warning in Event viewer.

Many of the flash memory devices also known as thumb drives or USB sticks fail with zero warning. These devices fail for many reasons. Some devices fail due to bad workmanship and others fail due to improper use. The most common failures are from obvious damage such as plugging a USB flash memory device into a laptop of desktop computer and banging it by accident causing the port of the device to become broken, bent or damaged.

Bad workmanship issues can cause USB flash memory storage devices to stop working at any moment. Manufacturers are constantly using cutting edge parts combined with outdated parts. When a manufacturer can save a few cents using say one type of circuit as opposed to the next more durable circuit on a USB memory device they will. For consumers this causes devices to fail faster and more easily.

When end users of USB thumb drives unplug devices during a read or write function the device can fail almost permanently. Devices that are made with proven parts will tend to function normally if the device is unplugged during a read or write functions. Some of the error messages some might encounter follow.

Besides, flash data recovery from Solid state hard drive with many chips inside, or from some micro chips, or encrypted chips like SanDisk flash memory, this is almost impossible with the current flash data recovery tools including the flash doctor, pc3k flash and flash extractor.

There’s news about one SSD data recovery tool called SD SSD which will be released to handle this kind of data recovery by SalvationDATA. SSD is still waiting for a better chance to replace traditional hard disk drives. The time for this process will last at least 2-5 years.
