Waleed, Michael, Thanks for both of you for your suggestion. I did dropped(tuncate did not work) the corrupted table, recreated usinf import from other database and compiled invalids. Full export error gone now. Thanks again for experimenting this issue. But dbv still gives the error pointing to one block as corrupt page 223 is influx most likely Media corrupt and page 224 is marked corrupt. Should I restore it from cold backup to get rid off this error?

Check there is no triggers on the table, also check other object dependencies on this table. Truncating the table and reloading it may work since it will not try to read the blocks.

After checking it was tracked=3D20 as a sys.table. dbinv alos points that corrupt block due media failure. SA=3D20 ran Compaq provided utility which says no corruption of media. Database is a development instance and no archive on. Simple way to restore=3D20 complete database from cold backup of previous week. Is there any other way to recover the table completely. DBMS_REPAIR package=3D20 does not look to work for complete recovery. Full export hanging after=3D20 generating errors for that block.
