Why Does The ExFAT Drive Won't Mount Or Unmount On macOS Ventura?

On my M1 Max, I've been having problems with exFat external drives constantly disconnecting after the Ventura update. I've administered first aid to them, and nothing seems wrong. The drives either disconnect every three to four minutes, which makes it impossible to work on a project, or they fail to mount even though they appear (greyed off) in disk utility. Prior to Ventura, they operated flawlessly on my Macs and functioned well on the PC. Though I've read hypotheses, what is the exact size and accuracy of the ideal block size required to satisfy Mac OS and exFat? Can Mac OS fix this problem, or do I have to erase every 5 TB of data on each drive and start over? Any advice would be appreciated.

Hi there, it seems that it's a bug or glitch of macOS Ventura leaving a hindrance to your exFAT drive in mounting on your Mac. For this issue, there are two options: one is to test the connection by a replacement of port, cable, or adaptor, and the other one is to update macOS Ventura to a higher version or reinstall macOS.
