Ok my bad I do not have a backup of the SD card from my PI 3b+. The card crashed and had ALL my flows and Arduino code. I have a new install on a NEW SD card setup and SD reader attached to the PI. I can see the SD card and folders BUT I don't know what I am doing as to where to look for the flo…

If you copy over the node red directory and all sub folders you will get all the nodes and flows you had before. That is a good node red total backup.

hello and thanks...but it's not that easy.. IE when I put SD card into the PI i see it come up as "boot" an Icon. when I double click it it load the file manager and I see "root" and "boot" if I click Root it throws this error "error mounting /fdev/sdb7 at media/pi/root. wrong fs type,ect ect if…

What are you trying to read the SD card in? It sounds like you can't see the linux files.

on PI 3b+ card pluged into the PI 3 with the card reader adpt.

You state the card crashed so it's possible that your file structure is corrupt and as such, unreadable. There may be tools you can run against the card to try to recover your data but I don't have any recommendations as to what those might be and I'm out of suggestions, sorry

Maybe something like - raspbian - Recover files from broken sd card (no boot) - Raspberry Pi Stack Exchange The files that you want to recover live in the root partition.

yes I agree but what I don't understand is why I can see all those file in the first place. if I plug it into a win 10 pc I see the files as well so I don't know. Thank you for your help I guess I just bit the bullet

[image] ronbu: f I click Root it throws this error "error mounting /fdev/sdb7 at media/pi/root. wrong fs type,ect ect if I click on "boot" in file mang. I get a folder called overlays and a lot of files like this "bcm2708-rpi.dtb." lots of them. Now on the left hand pane in F.M. I see folder l…

So then what I am seeing is the boot and not the root. Yep that's why I can't find them.. Ok thanks. Ronbu

[image] jbudd: Or you may need to attempt a repair using fsck , again specifying ext4. I did try that. it replied dirt found and asked if I want to repair I did but still no bootup. I will try the re-name and give that a shot. Thanks
