OP:
It's NOT WORTH THE MONEY to buy the 2 adapters.
You are better off to:
- Pry open the firewire case
- Take the drive OUT of the enclosure
- Buy a new USB3 enclosure ... or... a USB3/SATA docking station. The docks are great solutions to handling multiple "bare drives".
Doesn't the drive also have a USB2 connection?
What happens if you use a USB2 cable and plug it into the Mac?
HI, Fishrrman,
I believe I had a problem with this USB connection on that FW800 drive. I suspect the cable, because it has the small USB contact on the drive end, and standard USB on the other. (seemed kinda loose on close inspection)
I am pretty sure that this cable cost me the option to clone my CCC back up when I first started up my new iMac 2020. I did everything precisely as you detailed, and I never got the option come up to migrate anything. Then, after I went through the standard set up, I saw the USB drive had indeed mounted. I next tried apple migration assistant. it recognised the USB drive, so I selected what I wanted (photos/apps/settings only) and let it run.
I got the message "migrating your data" and starting up, so looking good, but I could not see any movement on the progress bar. Haven't not done this ever before, I had to assume it was just going to be a slow process. 40 hours later, I could still see no activity, so I cancelled the process and I could now see that absolutely nothing had happened! arghhhh....
So I suspect the the cable. I do have a bunch of USB cables lying around with the same connectors. I suppose I could try a different cable, but I got fed up and left everything to go use my shiny new 2020. I thought I would just get the adaptors and return to it later.
Now that I had a few days to think, I realised that I have another reason to have the TB fire wire option, because I have 20 or so mini DV tapes of video footage that I really should edit/move onto HD for BU. I have a Sony mini DV deck with is FW400, but I have the FW400/800 adapter, so the FW800 to TB3 will be required for that later.
I had been using this CCC BU drive (Western digital 2TB) as a single 2TB volume. Originally it was Rad 0.
I assume if I put it into a totally different enclosure, I will still see a single 2TB drive as before?
This is a classic case of somebody upgrading after 10 years from a reliable system to the latest standards, but caught out by a huge transformation in connection standards etc.
Incidentally, when I do finally access the CCC BU, do you have a suggestion which is the best way to move my old high Sierra library to the 2020 iMac?
I know you can use options, when photos start up, to select an external drive. In fact, its a bit tricky, because what I actually want is to keep my photos library on the external 1TB SSD I bought for that. I am thinking that I probably should move my system photos library onto that external SSD first, then merge the old CCC library on that SSD? Or move the old library onto the 2020 first, and then move it all to the SSD?
I am going to Back up the 1TB external SSD to a very large capacity TB-3 external HD. I will partition that so I have a separate volume for Photos, time machine and probably another CCC back up. In hindsight, the CCC BU wasn't much good to me, (going from HS to Catalina didn't help) a TM BU, would have been easier from what I have since read. to be frank, I never used to bother with Apple TM in the past.
Lastly, I will say I am absolutely blown away with the the speed of this iMac 2020. Not even the fastest option (3.8 8-core i7 5700XT) It starts up like lightning compared to before. 4k video files are just unreal to work with. Photos look fab on the 5k screen. Its funny because you get so used to a machine and its limitation and you don't realise you're actually down on your hands and knees crawling through the mud, whilst everybody is passing you so fast you didn't even notice them. I suppose history will repeat itself!
Many Thanks
PS. I do not see the video card glitch lots reported. I did see it on first start up and after updating, no sign, so thankfully Apple software fix.
