ERROR: cannot read block 15157 of hp_tran: Success

Please help

Please bear with us we are in process of upgrade but many servers are still using version 7.3.4 of PostgreSQL running on RedHat5

A certain table seems to be corrupt when trying to select everything from this table, it throws out an error. See the error below

db0303=# SELECT count(*) from hp_tran;
ERROR: cannot read block 15157 of hp_tran: Success
db0303=#

There is no problem with the disc

Please assist, I am a Juniour DBA,
