I have two Raspberry Pi 3's (BlackPi and WhitePi by color). Both run Buster from SD card. I cloned the SD card to two powered 2.5 SSDs. BlackPi SSD has Nextcloud installed. The second SSD has Apache web server and PHP installed. Both SSDs will boot on BlackPi, but neither will boot WhitePi from a powered USB hub or USB3/SATA cable. WhitePi boots from the SD card only. Is there a line of code missing related to OTP or cmdline.txt (or something even simpler)?
Also, I have been though the steps of reformatting WhitePi and reinstalling Raspbian from scratch twice. It will work in WhitePi for several days of use then stop being a bootable drive (except in BlackPi).
