OWC Drive Dock: USB Hot-swap Limitation

Created on: July 7, 2016
Last updated: April 19, 2022

Affected Part Numbers: OWCTB2U3DKR2 

When connected via Thunderbolt, you can power each drive bay on and off independently (and swap out either of the drives) without affecting the other drive. When connected via USB, it is possible to unmount either drive from the OS without impacting the other drive, but you cannot power a bay on or off, or physically connect or disconnect one of the drives, without causing the other drive to temporarily unmount. Depending on the hard drive, it may take several seconds for it to remount.
