I am getting this error when trying to connect the database engine (Sql Server 2008) using SSMS. any ideas to solve this problem? Thanks!
As the error message says, it sounds like master is not OK. You need to run a DBCC CHECKDB on master (run it on all of your databases to be sure). If you're lucky, it's a minor issue, or a problem with your I/O subsystem that is presenting itself as database corruption.
As CHECKDB author Paul Randal says, 99% of CHECKDB issues are caused by problems with your I/O subsystem, so making sure that you diagnose and solve the I/O subsystem issues should be your #1 priority right now.
For more info...
Look through your event log. It's basically saying
'I was half way through reading the data for the master database when the disk decided to tell me that it wasn't ready'.
This 'severe system-level error condition' bit isn't joking.
It's pretty likely though that you will see something in the error log at that time that tells you why that drive isn't being reliable.
