dbverify does not scan what is there in the sga. It just checks the datafile. You would droped the table, but that information is not flushed yet to the datafile, in this scenario if you run dbverify it will raise corruption error.

I think probably that's what happening in your case.

I think you have a block corruption here,

ANALYZE TABLE .. VALIDATE STRUCTURE CASCADE;
for the table, this is almost equal to dbms_repair command.

Else see 28814.1
