Recovery data of deleted files from FAT drive

Recover data deleted from Fat volumes

Tools have existed for data recovery from a FAT file system since the early DOS days, but there is little documented theory on how it should be done. Recall that when a file is deleted from within Windows, the directory entry is marked as unused and the FAT entries for the clusters are set to 0. To recover the file, we have the starting location and the size of the file. We have no information about the remaining clusters in the file.

We can try to recover the file data by reading the data from the known starting cluster. A recovery tool (or person) has two options when it comes to choosing the remaining clusters to read. It can blindly read the amount of data needed for the file size and ignore the allocation status of the data, or it can read only from the unallocated clusters. The second option will succeed more often than the first option because it will recover some fragmented files.

A final note on recovery is that multiple cluster directories are likely to be fragmented. This is because the second cluster is only allocated when it is needed and it is highly unlikely that the next consecutive cluster will be available (because that cluster was probably allocated to one of the files in the directory). Therefore, directories are harder to recover, unless the directory is the result of a copy or the file system has been recently defragmented. When a directory is copied and its size is known, then consecutive clusters could be allocated for it.

If a user frequently runs defragmenting software on her file system, recovery of the documents deleted after the last defragmenting will be easier because more of the files will be in consecutive clusters. On the other hand, files that were deleted prior to the defragmenting will be very difficult to recover because the clusters could have been reallocated.
