New external SSD not recognized on Ventura on Mac OS

I am not trying to obfuscate (render obscure) TM.

Please re-read my original post. I only mentioned TM as an example of the correct functioning of the SSD on another system.

Thanks again for mentioning the possibility of NTFS bing preloaded(It is not)

Further investigation with apple care using the recovery console and graphical diskutil revealed that one of 2 SSDs (Samsung) is quickly recognized, but the other is never recognized at all. Switching cables (no adapter is involved) did not help.

Apple Care suggested that the failing drive may not be receiving sufficient power and I might try getting a USB hub that provides power.

I notice a similar problem at https://discussions.apple.com/thread/254599224 with 22 me too s !

Thanks for your replies.

I did not install NTFS firmware and I don't think it was pre installed.

I don't think this problem is related to T i m e M a c h I n e (hopefully spaced word won't for found by search.) But I'll look into that.

It works fine on Monterey

Both linux and windows recognize the drive as having 2 partitions .

Linux disk reports:

Since this problem really has NOTHING to do with T i m e M a c h I n e

hopefully spaced word won't for found by search.
