Hi, We've got a table that the alert log is reporting as having a corrupt block: Corrupt Block Found TSN = 20, TSNAME = DEVELOPMENT RFN = 10, BLK = 28391, RDBA = 41971431 OBJN = 54369, OBJD = 54369, OBJECT = SKRSAIN, SUBOBJECT = SEGMENT OWNER = SATURN, SEGMENT TYPE = Table Segment I can create a copy of this table using "create table as..." and it doesn't issue an error. So does this mean that the corruption is an unused datablock and if so will the data in the copy of the table be intact? Thanks in advance. Steve
