Looks like the whole directory is screwed ORA-01110: data file 5: 'E:\DATA\ERICDATA'

unless of course you named the actual file ericdata which in that case if you did I'd like to know what you were thinking?

Hey Davey lets say hypothetically this poor sod did name his datafile "ericdata" and the data in that datafile was hypothetically expendable, then he could hypothetically take the datafile off line and blow it away. hypothetically speaking of course.
