Package: fdisk Version: 2.31.1-0.5 Severity: normal Hi,
I think I found a bug in sfdisk (or rather in libfdisk). I'm trying to (programmatically) add a partition filling the whole free space on an 64G sdcard after burning a raspbian lite image on it. Device preparation: wget https://downloads.raspberrypi.org/raspbian_lite_latest unzip rasbian_lite_latest dd if=2018-04-18-raspbian-stretch-lite.img of=/dev/mmcblk0 bs=4M conv=fsync The resulting partition table on the sdcard is: sfdisk -d /dev/mmcblk0 label: dos label-id: 0xc7cb7e34 device: /dev/mmcblk0 unit: sectors /dev/mmcblk0p1 : start= 8192, size= 88262, type=c /dev/mmcblk0p2 : start= 98304, size= 3538944, type=83 There's approximately 58G available at the end of the device (from cyl 3538944 to 125042688). According to the manpage, I think adding a new partition for a vfat filesystem filling the free space could be done with: echo "type=c" | sfdisk -a /dev/mmcblk0 But it doesn't seem to work: echo "type=c" | sfdisk -an /dev/mmcblk0 Disk /dev/mmcblk0: 59.6 GiB, 64021856256 bytes, 125042688 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xc7cb7e34 Old situation: Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 8192 96453 88262 43.1M c W95 FAT32 (LBA) /dev/mmcblk0p2 98304 3637247 3538944 1.7G 83 Linux /dev/mmcblk0p3: Created a new partition 3 of type 'W95 FAT32 (LBA)' and of size 3 MiB. /dev/mmcblk0p4: Done.
