WD exfat Partition recovery – recover data from deleted formatted lost damaged exfat partition from WD hard disk drive
WD exfat Partition recovery, recover data from deleted formatted lost damaged exfat partition from WD hard drive.
exFAT may be adopted with the Facts Association as the default file system for SDXC cards larger than 32 GiB.
When exfat partitions are deleted or formatted, the success rates of recovering big files or frequently modified files are very low. For example, it is very tough to completely recover the XLS or CDR files that are edited and modified frequently. But files remain untouched have a high recovery rate. For example, it is very very easy to recover PDF, JPG or MPG files who are not modified frequently. This is due to that this FAT or exfat partition applies file allocation table to record the info of cluster chain fragments of each one file. Following the deletion or formation, the info of cluster chain fragments will be emptied. For files are edited and modified frequently, due to dynamic boost in the file length, they often could be stored continuously from the file system, which ends the impossible recovery of file fragment information and thus incompletely recovered files

exFAT allows individual files larger than 4 GiB, facilitating long continuous recording of HD video that may exceed the 4 GiB limit inside of an hour or so. Current digital camera models using FAT32 will break it files into multiple segments of approximately 2 or 4 GiB. With all the increase of capacity along with the increase of data being transferred, the write operation should be made more effective. SDXC cards, running at UHS-I have a minimum guaranteed write speed of 10 MBps and exFAT plays an issue in achieving that throughput through the decrease in the file system overhead in cluster allocation. This is achieved through the introduction of your cluster bitmap and elimination (or reduction) of writes for the FAT table. One particular bit from the directory record suggests that the file is contiguous, telling the exFAT driver not to consider fat deposits table. This optimization is analogous to an extent in other file systems, except that it only refers to whole files, instead of contiguous parts of files.
