Backup failed #12

I attempted to backup the SD card in my Raspberry Pi 4 with the command:

# rpi-clone sda

I got this in response:

Error: /dev/sda: unrecognised disk label

At this point lsblk shows only mmcblk mounted. sda does not appear even after disconnecting and reconnecting. Is there a way to recover from this?

Are you sure /dev/sda exists before you run this script? Looks like it doesn't, and then this would be completely outside of rpi-clone?

Unclerojelio commented 6 months ago

lsblk showed that it existed before I ran the script.

lsblk showed that it existed before I ran the script.

I would try to insert the backup card in another USB slot. Maybe that one is defective?
