I moved the devices to different physical location and edited the device location in sysdatabases. the problem was I had to start the server to make the changes, which I did. however, master did not find some devices and marked the DB as suspect. One of the is model (status 320). I brought server in a single user mode but won't let me clear the suspect flag and won't let me drop the db "dbcc dbrepair(dbname,dropdb)"since it is a system DB.
