So what was the problem exactly when the drive had been recognized by the iPad?Yes, that's very likely true. I've had the same version of all those programs since I first got them., (with some minor updates). It's very possible that a new OS could cause something in them to spit the dummy.
I should have said, the drive was recognised, but it had the wrong name. Well, that is, I thought it was the wrong name, but i found out later that it wasn't. I know all my SSDs have insufficient power to work, but this was a powered one. Big Seagate brute of a thing.
I'm going to nab my nephew and pick his brain about iPads. He's a whizkid with them. In person, I'll ask a lot of annoying questions one after the other, and he'll have to tell me where I'm going wrong, hehe..
Cheers.
I just connected an external 4TB SSD to my iPhone SE2 with a Lightning to USB-A-Adapter. At first I didn't see anything in the Files app. Then I removed it while the Files App was open and connected it again and both partitions were immediately there. No power source needed.
