USB drive disconnecting/reconnecting randomly

2020 M1 MacBook Air running Monterey 12.6.3

Both SSD (SanDisk and Kingston) connected directly thru an unpowered j5 adapter, AND a Western Digital HD, used only for Time Machine back-ups, connected thru a powered CalDigit TBT4 Element hub are triggering "Disk Not Ejected Properly" messages at completely random intervals. Sometimes at the same time, other times not. The first common element is the Mac.
