One drive only blinks when accessed, one always is blinking

I have a MacBook Pro M1. Two identical Anker Hubs, one plugs into the left USB C port, one plugged into the right USB C port. Both disks are WD 5TB My Passport Ultra. The disk on the left port blinks constantly , the disk in the right port only blinks when in use. I had the second drive replaced under warranty, WD sent a “Passport 260F” this dive blinks only in use. the other disk is “Passport 260D”, it always blinks. Was there a firmware update that might cause the ?
