There are times when you try to access your database, and find out it is gone into the suspect mode which makes your data inaccessible, also restricts you to perform any transactions.

Why does this happen? What are the reasons behind going your database into the suspect mode? And how to remove database from suspect mode in SQL server ? The solution to all these queries is discussed in the further section. So, let’s find out!

What is a Suspect Mode?

Whenever SQL Server finds any database suspicious, it marks it as “Suspect” and puts database into suspect mode. There can be several reasons behind any database getting suspicious. The major reasons are, corruption in the database files, log files getting damaged, hardware and software failures, sudden shutdown of the database server and many other factors are also responsible for this issue.

Why Do We Need to Remove Database from Suspect Mode

If your database files have gone into the suspect mode, then it is not a good news for the user. The suspect mode forbids users to open or access their database file. As a repercussion of this phenomena, user becomes unable to perform transactions as well.

Major causes:

  1. Any kind of corruption detected by SQL Server in the database file.
  2. If the hard disk is running out of space.
  3. Due to missing / corrupted log files.
  4. If SQL is not able to execute the roll back or roll forward operation.
  5. If Hardware or software database corruption has occurred in SQL server.
  6. Any kind of virus attacks.
  7. Sudden shut down of the system while the SQL server is running some task.
Note: As a fact, it is seen that there are 85% chances of database going into suspect mode due to improper shutdown.”

Although we cannot directly control SQL server to take away our database file from suspect mode, there are some prevention hacks and solutions to recover SQL database in suspect mode.

Follow these tips to repair SQL database from Suspect Mode:

  1. Always keep your hard disk free in space. A full disk space tends to be the major reason behind causing corruption in the database files.
  2. Make a habit to create backups every now and then.
  3. Make sure to properly shut down your system.
  4. Always keep a check on your log files.
