Can't back-up Recalbox image...

[OyyoDams]

@supersaiyancurry yes exactly. You can try to restore on a bigger SD card, I'm sure it will work.

@oyyodams Welp, good news. I tried it with a different brand 32gb sd and it worked. Still makes no sense to me though... I feel like there's probably a way to solve this issue, but for now, I guess I'll only buy the Samsung 32 th Sd.

@supersaiyancurry you don't seem to get the point that the image is not properly restored, which corrupts the last partition on the sd, Linux refuses to mount it

[supersaiyancurry]

@substring well, I've tried a full overwrite format with SD formatter and that didn't work, so idk what else I could do.

[OyyoDams]

@supersaiyancurry once again, that's because your desination SD card is smaller that the source SD card. Format won't change anything, it's hardcoded in the SD card.

[supersaiyancurry]

@oyyodams but, like I've said, the 2 SD cards are EXACTLY the same. I literally went to the store and asked for 2 of the same thing.

[OyyoDams]

@supersaiyancurry and I repeat, you do think they are identical, but they aren't.

Believe me or not, believe @Substring or not.

You want to check by yourself ? I don't know any tool under Windows that will show the exact size of the SD card.

So if you really want to check:

1. Boot under Linux
2. Insert the 1st SD
3. Run blockdev --getsize64 /dev/XXX where XXX is the SD
4. Eject the 1st SD and insert the 2nd SD
5. Run blockdev --getsize64 /dev/XXX again
6. Compare the results

You'll be surprised.

Then return to your shop and complain if you want, and stop complaining here, it's not our fault!

So to my understanding is if my image is from 32gb sd card I can flash it to a 64gb SD card and everything should be there. I am having the same issue of backing up my image. I know not all SD cards are the same even tho they are the same brand.

@jaime-O
The SD cards may be physically the same, but it depends of the formatting tool. As example, first you use directly out of the package, ready formatted by company. Second, you reformat it with some program. So if the formatting tools are different, your usable size will be it also most of time.
Only possibility, reduce partition on your SD card by a tool like "Parted" with virtual linux system on your pc, but sure not under windows.

@jaime-o Although the subject to be related, the ideal is not "dig out" an old topic that was "stopped". Regardless, yes, it is possible to back up a 32GB card to a 64GB card. However, depending on the tool you use, the 64gb card can be only 32gb visible and the rest "unallocated", which is easy to solve: just use a tool to expand the size of the SHARE partition, for that partition to use all available space. (using gparted from linux is a great option, but some applications for windows, specific to partition HD, also work). (If you are using windows, you can use "SD Memory Card Formatter" to format the card, "win32-disk-imager" to copy the image and the same program to write to the new SD card, or "RUFUS", and if necessary, the "MiniTool Partition Wizard" to expand the SHARE partition after the backup.)
Please open a new topic, specify as much information as possible: If you are using Rpi0,1,2 or 3 (since you are talking about an SD card), which are the cards you are using (which should be original , and class 10), what is going wrong exactly, etc.
