By default LE will only recognise an eSata drive if it is connected at boot. To allow hot plugging of eSata devices you only need to do a few things.
1) Make /flash rw
2) Then make a backup of uEnv.txt
3) Edit /flash/uEnv.txt
and add ahci_imx.hotplug=1 to the end of the line. So it looks something like this
mmcargs=setenv bootargs "boot=/dev/mmcblk0p1 disk=/dev/mmcblk0p2 ${ssh_arg} ${console_arg} ${debugging_arg} video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 dmfc=3 consoleblank=0 ahci_imx.hotplug=1"
Save with <Cntl> O and Exit with <Cntl> X then reboot.
