BTW, here's the relevant bit of the strace output:
open("/dev/sda", O_RDONLY|O_LARGEFILE)  = 0
_llseek(0, 0, [0], SEEK_CUR)            = 0
close(1)                                = 0
open("/dev/null", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = 1
rt_sigaction(SIGUSR1, NULL, {SIG_DFL}, 8) = 0
rt_sigaction(SIGINT, NULL, {SIG_DFL}, 8) = 0
rt_sigaction(SIGUSR1, {0x80493a0, [INT USR1], 0}, NULL, 8) = 0
rt_sigaction(SIGINT, {0x8049390, [INT USR1], SA_NOMASK|SA_ONESHOT}, NULL, 8) = 0
clock_gettime(CLOCK_MONOTONIC, {70667, 216812381}) = 0
ioctl(0, MGSL_IOCSTXIDLE or MTIOCGET or SNDCTL_MIDI_MPUCMD, 0xbf8e31d0) = -1 EIN
VAL (Invalid argument)
_llseek(0, 31129600, [31129600], SEEK_CUR) = 0
read(0, 0x8059000, 512)                 = -1 EIO (Input/output error)

thanks,
