It has been several times since during the  restore of our db of prod we meet with corrupt dbf :
DBVERIFY - Verification starting : FILE = /data4/test_data_07.dbf
Page 1412419 is marked corrupt
***
Corrupt block relative dba: 0x51d58d43 (file 327, block 1412419)
Bad check value found during dbv:
Data in bad block -
 type: 6 format: 2 rdba: 0x51d58d43
 last change scn: 0x0011.cf2ec495 seq: 0x1 flg: 0x06
 consistency value in tail: 0xc4950601
 check value in block header: 0xf7cf, computed block checksum: 0x40
 spare1: 0x0, spare2: 0x0, spare3: 0x0
***
How is it possible?
Why dbf restored can be corrupted and not in the production?

Thanks
