I've created a bash script for that, seems working fine:
#!/usr/bin/env bash
# comment to run
exit 1
size=14680064
drive=sdb
{
echo "label: gpt"
# echo "label-id: 89B1365E-CD48-4A4C-95FB-117A92909321"
echo "device: /dev/$drive"
echo "unit: sectors"
echo "first-lba: 2048"
# echo "last-lba: 1953525134"
echo
# exFAT type=EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
# NTFS type=EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
# ext4 type=0FC63DAF-8483-4772-8E79-3D69D8477DE4
for i in {0..127}; do
echo "start=" $(($i*$size+2048)) ", size=$size, type=EBD0A0A2-B9E5-4433-87C0-68B6B72699C7"
done
} | sfdisk /dev/$drive
# comment to run
exit 1
for i in {1..128}; do
mkfs.exfat -n $i "/dev/$drive$i"
done
Thank you, @Robert!
PS. Don't mess with partitions near midnight! You can loose data!
PS2. Will try sgdisk later, thanks, @phuclv!
