Stop and disable the USB arbitrator service.

/etc/init.d/usbarbitrator stop
chkconfig usbarbitrator off

List disks:

ls /dev/disks/

Create USB-datastore1:

partedUtil mklabel /dev/disks/t10.SanDisk00Ultra_Fit000000000000004C530000131203104454 gpt
eval expr $(partedUtil getptbl /dev/disks/t10.SanDisk00Ultra_Fit000000000000004C530000131203104454 | tail -1 | awk '{print $1 " \\* " $2 " \\* " $3}') - 1

Replace ----- below with output:

partedUtil setptbl /dev/disks/t10.SanDisk00Ultra_Fit000000000000004C530000131203104454 gpt "1 2048 ----- AA31E02A400F11DB9590000C2911D1B8 0"
