DietPi v9.7.1 : 23:24 - Mo 30.09.2024
─────────────────────────────────────────────────────
- Device model : RPi 3 Model B (aarch64)
I copied a new, current DietPi installation on SD card to and copied it to SSD with
dd if=/dev/mmcblk0 of=/dev/sda bs=1M status=progress
root@DietPi:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 953,9G 0 disk
├─sda1 8:1 0 128M 0 part
└─sda2 8:2 0 14,5G 0 part
mmcblk0 179:0 0 14,6G 0 disk
├─mmcblk0p1 179:1 0 128M 0 part /boot
└─mmcblk0p2 179:2 0 14,5G 0 part /
After removing the SD card, dietpi cannot be booted from the SSD.
the command does not work:
-bash: diepti-drivemanager: Command not found.
How to select the boot partition on the SSD? Do I have to mount?
dietpi-drive_manager can be started
I probably have to mount sda1 as boot
my knowledge is not sufficient
Can anyone help me?
How do you copied the data from SD card to SSD?
Shown above:
dd if=/dev/mmcblk0 of=/dev/sda bs=1M status=progress
I assume.this was a copy of a running SD card to the SSD.
Could you check the prerequisites for an USB boot like e.g. described there:
Yes, you should follow these instructions as they apply to RPi3 in general and dietpi is a lightweight version of the raspberry debian.
Usually RPi3B should be able to boot ootb. Just move the system using dd command as described on our blog post Moving a running DietPi system to a USB stick/disk or an onboard eMMC – DietPi Blog
have gone through the list: do I have to adjust the path/to/image.img?
after
root@DietPi:~# sudo dd if=/dev/sda of=“/path/to/image.img”
the error message appears
Cannot open ‘/path/to/image.img’: File or directory not found
You are trying to flash a new image or do you like to copy your SD card?
so I should copy that again?
dd if=/dev/mmcblk0 of=/dev/sda bs=1M status=progress]
Depends on what you like to do. Am I right, you like to copy your existing SD card?
ok - so i copied the sd card again as described
After removing the sd card the device does not boot correctly
→ the IP is not available
boot is possible after inserting the sd card.
Here is the data again:
root@DietPi:~# lsblk

├─mmcblk0p1 179:1 0 128M 0 part /boot
└─mmcblk0p2 179:2 0 14,5G 0 part /

Is the SSD partition with boot marked as bootable in fdisk/cfdisk?
That should be ok according official RPI docs https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#raspberry-pi-2b-3a-3b-cm3-cm3-zero-2-w
Do you have a USB pen stick available? If yes, can you flash a new image directly to USB stick and try to boot?
Thank you,
before I repeat everything again with the USB stick:
An SSD is connected with this adapter:
Raspberry Pi X820 V3.0 2.5 Inch SATA HDD/SSD Storage Expansion Board with Case for RPI 3 B+ (Plus) / 3B / 2B -
should be connected analog to USB boot - right?
nothing to be repeated, simply flash a new image to USB stick and check if it is booting.
Hello
booting from the USB stick - (has been given the name SDA) works!
root@DietPi:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 1 14,9G 0 disk
├─sda1 8:1 1 128M 0 part /boot
└─sda2 8:2 1 14,5G 0 part /
sdb 8:16 0 953,9G 0 disk
├─sdb1 8:17 0 128M 0 part
└─sdb2 8:18 0 14,5G 0 part
Ok so problem is not with USB boot in general. More with this extension board. Probably it takes to long to detect the SSD 
So that would be a problem with the hardware?
Couldn’t I install the Ditpi software on the SSD and work with the SSD after booting?

Maybe problem with the USB2SATA adapter that doesn’t support booting or needs some tweaking in BIOS/UEFI.
after I removed the USB stick (also without SD card) rebooted - it works now
Thank you very much
