Internal SD card corrupted


#1

Hi, SD card in my internal raspberry inside the printer got corrupted, does anyone have an image I can load to a fresh card to replace it? I have tried to contact support, but it seems to be taking a long time for them to respond.

Nope, but i think bless cat will respond in some time, Good Luck!

Thanks, but I will need full image to create a new working SD card, your backup only contains the first partition. From what I have found out there are 3 partitions on the card:

Disk /dev/sdd: 7.4 GiB, 7948206080 bytes, 15523840 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000

Device     Boot   Start      End  Sectors  Size Id Type
/dev/sdd1  *       8192   131071   122880   60M  6 FAT16
/dev/sdd2        131072  5373951  5242880  2.5G 83 Linux
/dev/sdd3       5373952 15523839 10149888  4.9G 83 Linux

the third partition looks like user data, I can see last .stl files I printed there. The one I need to recover is the second one that contains the system.

When I copied your backup to the first partition and used second partition from my damaged card, then connected monitor to the internal raspberry I can see that it starts booting, but then there are some segmentation faults and the printer fails to start properly.

The copy is exactly copied from a OEM SD card. You should copy right over your SD card.

You’ll need to write the disk image to the SD card, not just transfer the files. That might be the disconnect here. Win32 Disk Imager is the program that I use for this.

Here’s a tutorial that I made for another program that uses a similar process.

Thanks for a tip. Let me try a back up image on my printer for me or others that might need.

The same program will allow you to capture a bit for bit image of the drive, too. There’s more information there than windows explorer will recognize as a file. That’s the root of what’s going on.
