Ive found that after putting the s2400 in USB MSC I cant eject it? Seems if I either attempt to bin the S2400 drive icon or click eject - it disappears for a second then comes back onto my mac screen.
Sounds like you’re on Mac. No need to eject the drive just hit back on the s2400, or hit back and then eject if you don’t want the “disk not ejected properly” pop up. The s2400 will be fine either way regardless of the popup.
I think you also asked this on facebook.
You do not eject from the computer side, it will keep coming back up.
Just press back on the s2400.
