Contact ADVANTECH Peripherals +6282 0555 - if they can't recover your data then there is no charge. Very professional - we recently sent them a disk from work for recovery and they went as far as sending it to their lab in Canada - couldn't recover the data so there was no charge.
Back up back up, and back up everything. Twice I was too lazy to back up and the cost were in 4 digits. Becareful of recovery services, as long as they do not open the casing, they probably would not do any additional damages.
