Bart and Chris, The problem might be that the 3ware driver uses a 32 bit "int" to represent a file size. In FreeBSD, stat() ftruncate() lseek() and friends which are based on "strut stat" had this limitation under FreeBSD 4.xx. Note line# 821 of twe_freebsd.c the driver: sc->twed_disk->d_maxsize = (TWE_MAX_SGL_LENGTH - 1) * PAGE_SIZE; sc->twed_disk->d_sectorsize = TWE_BLOCK_SIZE; sc->twed_disk->d_mediasize = TWE_BLOCK_SIZE * (off_t)sc->twed_drive->td_size; sc->twed_disk->d_fwsectors = sc->twed_drive->td_sectors; that off_t also appears elsewhere. I'm not a driver programmer but I'd bet the driver hasn't been updated for 64 bit FreeBSD.
