Is target disk mode no longer supported on Catalina? Doesn't connect between MacBook Pro and 27" iMac.

MacBook Pro 13″, macOS 10.15

Target Disk Mode is not an OS feature but a firmware feature. AFAIK even the newest Macs still support Target Disk Mode:

Catalina on an EHD Running Sierra on a late 2013 iMac. Loaded Catalina on a 1TB Crucial SSD EHD. No real problems switching between OSs. However on Disk Utility the Catalina volume is not on the Crucial EHD, but on Apple APFSMedia. And running First Aid doesn't work on either Catalina volumes. Is this or can this be a problem?

could not show the portable hard disk? when I update to macOS Catalina, my macbook could not use portable hard disk any longer. When I connect the hard disk to the macbook, the flash-light of hard disk is on which shows that it is reading the data, but my macbook did not show the location of the disk. I could use my portable hard disk with my macbook before, could anyone help me to solve the problem?

Thank you, I've done this many times in the past, so maybe it's the Thunderbolt cable or port.
