Device name : /dev/hda Device st_dev : 00000301 Device st_rdev : 00000300 Device st_size : 0 Device st_blocks : 0 Device st_blksize : 4096 Device name : /dev/sda Device st_dev : 00000301 Device st_rdev : 00000800 Device st_size : 0 Device st_blocks : 0 Device st_blksize : 4096 Device name : /dev/sdb Device st_dev : 00000301 Device st_rdev : 00000810 Device st_size : 0 Device st_blocks : 0 Device st_blksize : 4096 Device name : /dev/sdc Device st_dev : 00000301 Device st_rdev : 00000820 Device st_size : 0 Device st_blocks : 0 Device st_blksize : 4096 So, in a PORTABLE way, how do I find the block device with a certain size, perhaps even the largest or smallest? I need to have a customer plug in an external drive (USB) and be able to determine if it's big enough for a raw-data write (no file-system).
