Flash drives have become a versatile medium for everything from computer data, mp3 players, and digital cameras. It replaced the floppy disk as a way to transfer data around it. Flash drives are solid-state devices and, therefore, do not contain moving parts. When connected to a USB drive, the computer automatically recognizes the flash drive without the need to install additional software. Measuring the life expectancy of hundreds of thousands of write-off cycles, flash drives are expected to last up to 10 years. This is more than twice the hard disk.
However, the ability of the flash disk increases the possibility of damage due to environmental factors. Regardless of the usual causes of drive failure, flash drives may get wet in the rain, and the cover may shatter when accidentally dropped, or it may be damaged while in the camera.
The difference in data storage between the flash drive and the regular hard disk drive or floppy disk is due to the data on the chip. This allows really random access across the entire media. In fact, the disk access algorithm makes sure that the data is distributed evenly across the data sectors using the "wear corrosion algorithm". Flash disk contains a limited number of writing or scanning cycles. If he were to continue writing to a specific sector, that sector would be depleted of use much earlier than other sectors. The wear correction algorithm ensures that the sectors wear out evenly. Also due to the wear correction algorithm, when the data sector disappears, the rest of the disk will surely follow it quickly.
In some cases, the camera cannot distinguish between the file system on the flash disk and enforcing the format. Early flash drives use FAT12 or FAT16. FAT32 is being used by large-capacity flash drives of the current generation. If the digital camera fails to detect the capacity of the flash drive, it may wrap around the data while writing pictures and excess write system areas.
There are times when a flash disk cannot be read by a computer. Although this is due to the computer, it is an error caused by turning on the camera or MP3 player. Unplugging the drive while writing its data may damage the flash drive.
Flash data recovery in most ways is similar to recovering from any other media using FAT. The only difference is the location of the media files. Data can be recovered using FAT-capable data recovery tools. Usually for cameras, the file structure is fixed. The camera's limited operating system will write to a specific folder in the directory. The same applies to MP3 players. Mp3 files must be in a specific directory in order for the mp3 player to locate and play them. Some specialized tools search for the specified folder where the media files should be.
Processing all data on disks as data files, disk recovery programs, or other utilities are capable of correcting any errors. The Windows CHKDSK utility treats the disk like any other drive.
In case of data loss, flash data recovery is like recovering data from any other medium, but with slight differences. Since the data is stored differently, there are more tools available to recover Flash data. Available tools and utilities include Flash data recovery specialized in image or mp3 music files. Other specialized utilities that can be used to recover Flash data are those that specifically recover data from FAT drives. If the photos were accidentally erased from the camera, these tools will be able to recover them and recover the image.
In some cases, data recovery can be simpler. A flash disk restored from a lake or wet from the rain may still be used after ensuring that the circle is completely dry. A flash disk with a broken case may be usable. Either way, it would be nice to test first by plugging it in. If the drive is still readable, just copy the files before deciding what to do with the flash drive.
