Check the disk with smartctl(8) from the sysutils/smartmontools port to ch= eck that this isn't a hardware malfunction. If it is a hardware malfunction, the disk is dying and should be replaced ASAP. If the hardware is OK, try fls from sysutils/sleuthkit. As long as the data isn't overwritten, it should still be there.
