I was using an old 320GB 3.5HDD on my Raspi B+ with an external case. I moved to the disk the swap file and the dietpi user data and worked OK the last year. I bought a new external 4TB HDD and put it on the Raspi, so I returned the swap and dietpi user data to my sd (64GB) to disconnect the old disk. Everything went ok until i tried to unmount the old disk:
On dietpi-drive_manager I try to unmount the old drive and always fail. I tried to change the fstaab erasing this disk information and did not work. I have rebooted a lot of times an nothing seems to work. I did not unplugged the disk until i can unmount it because I am afraid my system gets frozen.
Can anyone tell me how to force unmount the drive? The order unmount does not exist in the system and when I try:
dietpi-drive_manager umount [/dev/sdb1|/mnt/Datos]
this is what i got:
-bash: /mnt/Datos]: No existe el fichero o el directorio
