Why should I unmount USB flash drive when prepare a USB installation of Proxmox? -


according official document of proxmox:

make sure usb media not mounted , not contain important data.

when making usb proxmox installation have make sure usb media not mounted on specific step.

but why should unmount usb media? difference?

as far know if usb mounted, dd return error stating disk/device in use. you'll have unmount usb disk first , use dd to create bootable usb disk proxmox .iso image. dd works @ block level , copies standard input standard output. in case standard input proxmox iso file , standard output usb disk. suppose issue man dd or read dd documentation more informations.
