    I picked up a Lacie Rugged TB/USB3 1TB hard drive (older one without the built in cable) with the plans on replacing the internal HDD with a SSD. I decided the 850 EVO should be plenty fast and a better value than the 850 pro, but upon installing it into the enclosure, it doesn't plug n play detect like it should (finder, disk utility, diskwarrior. Nothin).

    I discovered that the drive does detect and work fine if it's plugged into thunderbolt into my macbook air and is booted with it plugged in, but the same doesn't apply when connected via USB 3.0. Problem is, my thunderbolt port on my mac mini is occupied by my Lacie d2 TB which is daisy-chained into my non-TB monitor. I tried moving my monitor to the HDMI port, but that failed to work with a HDMI-DisplayPort cable (monitor found no signal), so I'd like to be able to use it on USB 3 until I can justify buying a thunderbolt dock.

    Power to a SSD via USB shouldn't be much of a problem, so I'm not sure why it's having issues. It worked fine with the HDD.

    Any thoughts on the hard drive or even the HDMI-DisplayPort issue?

    I'm having the same problem! USB doesn't work but thunderbolt does. Anyone?

    On the monitor situation, HDMI to DisplayPort requires fancy cables or adapters designed specifically for that direction of signal travel. Most cables and adapters only work in the DisplayPort to HDMI direction due to the fact that DP already contains an HDMI signal, while HDMI doesn't by design contain a DP signal.

    EDIT: Just realised this thread was started quite a while ago. Still, hope it's useful to someone.
