With FAT disks a common problem is for files to be limited in length. The length is always a value such as 4K, 8K, 16K. The most common reason for this is beacuse the file allocation table has been corrupted or blanked. The cure though is simple in that the disk should be read using the Ignore FAT button. This will read the file sequentially for the correct length. The problem is that as the FAT has been lost, so have details of possible fragmented files. Heavily edited files, or long files may not read correctly and data carving may be necessary to regenerate a readable file.
