I format my Crucial MX500 SSD - CT1000MX500SSD1 - 1 To - Serial ATA - SATA 6.0 Gb/s recommended by Umbrel in ext4 thanks to EaseUS software
I did also new clean install on my microSD card of Umbrel v0.4.9 but my Raspberry Pi 4 model B - 8GB keep having a red light and no install occurs 
Do you want me to open another ticket?
