WD exfat Partition recovery, recover data from deleted formatted lost damaged exfat partition from WD hard disk.
exFAT has been adopted by the Sdcard Association as the default file system for SDXC cards bigger than 32 GiB.
When exfat partitions are deleted or formatted, the success rates of recovering big files or frequently modified files are extremely low. For example, it is extremely tough to completely recover the XLS or CDR files which are edited and modified frequently. But files remain untouched enjoy a high effectiveness. For example, it is extremely easy to recover PDF, JPG or MPG files that are not modified frequently. This is due to that the FAT or exfat partition applies file allocation table to record the info of cluster chain fragments of each one file. After the deletion or formation, the info of cluster chain fragments will probably be emptied. For files are edited and modified frequently, due to dynamic rise in the file length, many of them can be stored continuously in the file system, which ends the impossible recovery of file fragment information thereby incompletely recovered files
Use “unformat” to recoup data from formatted exfat partition from WD hard disk after quick format,full format,accidentally formatted,reformatting,High-level formatting,Low-level formatting.
Use “recover partition” to recoup data from deleted exfat partition from WD hard disk
,lost exfat partition,changed exfat partition,damaged exfat partition from WD hard disk.And when the size and style or position of exfat partition is modified by format,It can not recover with “unformat” ,in order to use “recover partition” mode.
Use “undelete” to recoup deleted files from exfat partition WD hard disk after Virus attack,Trash clear,disk cleanup,Press shift del by accident,permanently empty bin,shift delete ,accidentally deleted by way of a mistake.
Use “Full Scan” to WD exfat recovery that may stop found with “undelete” and “unformat” and “recover partition” after showing an oversight,display as raw file system,unformatted,unknown partition,unpartitioned,needs to be formatted.

exFAT allows individual files bigger than 4 GiB, facilitating long continuous recording of HD video that may exceed a few GiB limit in less than one hour. Current cameras using FAT32 will break the recording files into multiple segments of around 2 or 4 GiB. Using the increase of capacity as well as the increase of information being transferred, the write operation needs to be made more efficient. SDXC cards, running at UHS-I have a minimum guaranteed write speed of 10 MBps and exFAT plays one factor in achieving that throughput through the reduction of the file system overhead in cluster allocation. This is done through the introduction of a cluster bitmap and elimination (or reduction) of writes on the FAT table. An individual bit in the directory record shows that the file is contiguous, telling the exFAT driver to disregard fat deposits table. This optimization is analogous with an extent in other file systems, other than it only relates to whole files, in contrast to contiguous areas of files.
