I'm receiving the following error when trying to repartition and reformat a USB flash drive via parted using a simple script. The bug follows: /sbin/parted -s /dev/sdb mkpart primary fat32 Backtrace has 14 calls on stack: 14: /usr/lib/libparted-1.8.so.0(ped_assert+0x3b) [0x10af3b] 13: /usr/lib/libparted-1.8.so.0 [0x146194] 12: /usr/lib/libparted-1.8.so.0 [0x146f4d] 11: /usr/lib/libparted-1.8.so.0 [0x1483c7] 10: /usr/lib/libparted-1.8.so.0 [0x1103e7] 9: /usr/lib/libparted-1.8.so.0(ped_disk_add_partition+0x295) [0x112e65] 8: /usr/lib/libparted-1.8.so.0 [0x14a2c3] 7: /usr/lib/libparted-1.8.so.0 [0x14a505] 6: /usr/lib/libparted-1.8.so.0(ped_disk_new+0xa3) [0x113c23] 5: /sbin/parted [0x804e2ef] 4: /sbin/parted(non_interactive_mode+0x7c) [0x8052c9c] 3: /sbin/parted(main+0x58) [0x8050f58] 2: /lib/libc.so.6(__libc_start_main+0xdc) [0x94cebc] 1: /sbin/parted [0x804b521] You found a bug in GNU Parted!
