One can use a third party tool because it not only help you to recover your data but also help in compressing MDF File with no time. It is highly accurate. SQL Server Database Recovery Tool has dual recovery mode which helps you to handle error on different stages that are Standard and Advance. It can run on all the version of windows OS. This software helps to repair corrupted MDF file and retrieve data saved in a new MDF file.


According to me, the third-party tool should be used only at that time when you are not left with any other option. While one should go for the manual method because they are easy to use and inexpensive. When you are not technically much strong than rather than using manual method go for SQL Database Recovery tool.
