Hooking up 2TB or 4TB USB drive as datastore in VMWare 6.7?

[YORKLY]

Good day folks, trying to add 2TB or 4TB USB drive as datastore in VMWare 6.7 and it is not detecting it.   However 80gig USB drive seems to work fine.   I know there might be a limitation but I would expect it should be to do it by now.   Is there another option to workaround this issue?

Thanks.

If you search google on this topic you will find workarounds.
See for example:

But IMHO none of them is suitable for extended production use.
Probably your USB-disks use harddisks that can also be attached to local SATA ports.
That option will be much more reliable and perform better.
