Haven't heard from OWC as to how their testing is going. I assume they've had no problems. Nor have I ordered a drive to put into the old OWC multi-port enclosure to test on the newly arrived MBP. The tech did say he thinks my enclosure is the problem but I'm not interested in paying for another repair...
I can say that the Seagate drive is still working perfectly with the Seagate adaptor I got for 20 bucks!!
And it's amazingly cool running, also, which is great since there is no fan involved. I've purchased some styrene pieces and sheets to create a more stable setup. Pictures at 10...although the date is unknown!!!
