badblocks fails on large drives due to 32 bit value

[fennectech]

[fennectech@jasper ~]$  sudo badblocks -nsv /dev/sde
[sudo] password for fennectech: 
badblocks: Value too large for defined data type invalid end block (23441833984): must be 32-bit value

we should switch to 64 bit values for these values to make badblocks functional on drives larger than 4tb
