Alright!! It took a while, but I finally got the OWC Mercury 3G 120GB SSD. Just put it in the machine, started it up and used Drive Setup to partition the thing. Then I simply copied all the files/folders from my recently done clean installation of the OS9 I downloaded from right here aaaaaaand.......tadaa! Works like a charm
So there really was a communication problem between the Samsung Evo 850 and the Sonnet TSATA. With the OWC, everything was done in about 5 minutes. And I got it for 80 bucks from Amazon.de, even cheaper than the Samsung 840 would have been.
Good times
Thanx again for your help, guys!
p.s. By the way, how cool is it that with OS9 one can just copy the system stuff and get another startup drive? I know, this is old news, but it still ROCKS!! I put a new HDD in the G4 recently and installed the latest OS9, so my old HDD is just for backup now. Then I installed Cubase and a bunch of plugins, as well as the MOTU drivers needed for my interfaces. And now, all I had to do was to drag all that over to the SSD. AWESOME!! AAAAAAAWESOME!!
