hello can someone say to me if a total dump of the sd( after rednand dump) with dd is safe enough or does i have to dump it with sdnandextractor on windows?
i've used dd in=/dev/mmc of=nand.bin
this 64gb file can generate the 3 .bin files like sdnandextractor right?
-this 64gb is a complete dump of the device, just make sure you are not only dumping a partition you have to dump the device.
-as it is a complete dump its a save backup
-those 3x .bin files are data somewhere in this 64gb image yes
if you need those 3x .bin files you have to set the proper boundary instead of dumping it completely.
Linux/OSX dumping instructions
No warranty but this should work for 32gb (and if adjusted for 8gb) wiiu and dump slc, slccmt and mlc into the current directory.
You need to know:
- The device name of the SD card in your system
- What kind of WiiU you are using (8GB or 32GB)
What you should do/adjust:
- You need to change the source to your device (not partition 1 on the device)
- If you want to backup the dump from an 8GB wiiu change "MLCSIZE=$MLCSIZE32" to "MLCSIZE=$MLCSIZE8"
- Unmount the first partition of the sdcard (if mounted)
- Add relative or absolute path to destination directory if wanted
- Add shebang if wanted
- Make it executable
- Run the script
The Script:
SOURCE=/dev/disk2
DESTINATION=.
BLOCKSIZE=512
I've checked that the shasum from both methods are the same!
Btw. it probably makes sense to make the start-stopbits for each image a constant instead of calculating them.
I added blocksize as a variable as it could improve writespeed not using the default.
Might also be usefull to use variables for the output filenames.
