Stellar Repair for MS SQL will not be able to run if the database is attached to MS SQL Server. Moreover, you should make a copy of your database and run recovery on this copy instead of the original file in order to mitigate the risks of any accidental damage to the file.
The software by itself is equipped to prevent any modifications to your database. However, if something goes awry (power spike, system glitch), you may run the risk of damaging the database structure or the contents of your database file.
