I use disk init build a "mytempdb.dat",and
alter database tempdb on mytempdb = 200
but i don't know,i delete the master device in "default" , then can not
add master again. the message is :'master' reserved exclusiely as a log
the 'logsegment' add mytempdb the message is: this command hsa been ignored.
txtending the log segment on device 'mytempdb' would leave no space for
creating objects in database 'tempdb'.
help me!
