Issue 3：	No sense of Logical Damage. They use to purchase some data recovered tools from the current market, such as Ezrecovery. However, they should make sure the recovered data is accessible before rewrite it back to the client's original hard drive.
Issue 4：	No professional knowledge of FAT32, NTFS, and File System...etc. They hazard to change the framework of File System to make more serious damage of inner framework of data.
Issue 5：	No professional knowledge of RAID. Take out the hard drive freely, and rebuild, or re-initialize RAID will make RAID Configuration more seriously.
