IDES ECC 6.0 SR2 installation error (Urgent)

Dear Experts,

I am installating IDES ECC 6.0 SR2.At "Import ABAP" phase I am getting error msg regarding a specific datafile.

Please find error msg of log file "SAPSSEXC.log"

ORA-01115: IO error reading block from file 84 (block # 27613)

ORA-01110: datafile 84 : 'F:\oracle\DBX\sapdata4\DBX700_25\DBX700.DATA25'

ORA-27091 : unable to queue I/O

ORA-27070 :async read/write failed

OSD-04006: ReadFile() failure. unable to read from file;

O/S error: (OS 23) Data error (Cyclic redundancy check)

I understand that there is some problem with datafile "DBX700.data25" from above msg.I have no backups to restore that datafile. Now how can I solve this problem?

Please help me regading this issue.

Many Thanks in Advance.

Regards

Aditya Kumar
