Pi-top USB boot Install (RPi4)

Continuing the discussion from [Guide] pi-top USB boot Install (RPi4):

I would like to say thank you to CAProjects and duwudi for the instructions and insights in this project of Booting the Pi-Top[4] from a USB SSD/HDD. I’ve wanted to do this since I received the Pi-Top[4], I don’t like using SD cards (personal preference - fat fingers). Since all of my Pi 4B systems boot off of SSD or HDD’s I was happy to find your instructions. I found a 1.5 TB Seagate HDD with nothing really important on it, I thought I’d give it a try. I experienced 2 real problems; the first was updating the EEPROM firmware. Performing the alternate way by doing the full-upgrade did not update EEPROM, so I did it using a SD card. The other problem was waiting for the File System expansion - it gave me an error. Informing me to power off and try again. I did and experienced no other problems. Now all I need to do is purchase another USB 500 GB SSD to change my Pi-Top[4] 8 GB system. Now I need to design something to attach the SSD to the pi-Top[4} when I am using it with the robot, might give me a reason to get a 3D printer.

Again thank you

the expanding file system issue seems to be with drives over 500GB , i think it times out. i got this issue with a 1TB drive but not with a 500GB

Thank you for that information. The Seagate 1.5 TB is the largest drive I’ve installed on any of my Raspberry Pi’s. I have installed 1TB USB HDD Drives and not experienced any problems. I plan on ordering 2 - 500 GB drives later today, 1 is designated for my Pi-Top[4] 8GB.
