USB Flash Data Recovery
An Introduction To USB Flash Data Recovery
Flash devices now make it possible to store massive amounts of data on small portable devices that would have previously needed dozens of floppy disks to store. The downside to this is that there is more information to lose if you delete or format the flash card by accident. This article is a guide to USB flash data recovery covering how software is technically capable of retrieving your files.
The key benefit of flash memory is that it uses the FAT-32 file format for administering data. This is the same file system as is used in Windows based disk drives and explains why flash devices are so easily recognized by Windows when inserted into a port.
The real benefit of using FAT-32 is that USB flash data recovery can therefore be achieved using the same applications that work on hard drives. There is a huge array of applications to choose from, commercial and freeware (e.g. PhotoRec, Recuva).
All these tools operate by scanning the drive for data clusters (each of your documents are stored to memory as numerous data clusters) and reading the file allocation table (a system file listing all documents, and associated data clusters, on the drive). The commercial ones have the greater potential of finding more documents if the FAT has been damage by piecing together the data clusters.
The applications should be able to find deleted/formatted documents as these files are not completely wiped from memory (only the index in the FAT is altered). However, the chance of USB flash data recovery success will diminish if the device is continually used for saving more documents, as this overwrites your lost document’s data clusters.
If there is mechanical damage to USB flash device then software will be ineffective. A PC repair shop or data recovery expert may have appropriate memory reading devices and computer maintenance programs to recover your data in this cas
