Data Recovery Service
Flash cards have made it so easy to store volumes of data that would have formerly fitted on thousands of floppy disks. The downside though is that if the flash device is deleted or formatted then the data recovery process has more files to find. This article looks at how data recovery software is capable of finding your files and points out some of the nuances of flash memory.
The big positive thing about flash based devices is that they use the same FAT 32 file system common to many internal hard drives and other forms of external storage devices. This means they need to have a file allocation table (FAT), master boot record and a boot sector.
Logical Drive Failure When an operating system becomes corrupted or unstable, it is called a logical failure. Common causes for logical failures are improper system shutdown, failed software installations, deletion of critical system files and corruption caused by virus and malware attacks. Logical drive failures require a different approach than simple file deletion; nevertheless, the computer user can still employ a software-based solution. The best solution is to use an emergency boot disk that bypasses the operating system and runs the computer from the disk.
You should be able to find a data recovery service that will examine your damaged data and determine whether or not it is recoverable - Diagnose. This part should be free.
They all operate in the same manner by reading the FAT to identify files (even deleted ones are indexed in the FAT) and scanning the flash memory for signs of data clusters (how each file is stored). The commercial tools will have a better chance of finding formatted data by analyzing the data clusters and reassembling the recognizable documents you work with.
One thing to keep in mind is the lifespan of flash memory. Each memory switch will fail after a certain number of read/write commands. For regular users, this could take decades to occur.
But if you use the flash card for running software (including and operating system) then the memory will fail quicker, so be warned, that data recovery will not be possible once this mechanical failure occurs.
