    SubjectRe: lseek("/dev/hda1", 0, SEEK_END) returns 0

    the BLKGETSIZE ioctl returns sector size of block devices (ie,
    /dev/sda1). but don't sector sizes vary as well? there doesn't seem to
    be an ioctl to get sector size, unfortunately.

    No, the sector size is always 512; or at least, it should always be 512,
    for the purposes of the kernel/user-mode interface.
