[Q] how to recover damaged sd card, internal? - Android Q&A, Help & Troubleshooting

Hello,
my device: "superpad flytouch 8" Android 4.04, kernel version 3.0.8+ [email protected] #68.
its rooted.
I got two internal storage partitions, they are mounted as sdcard(6gb) and sdcard2(30gb).
now when i plug it via usb, both drives get mounted in windows7. since fat32 cant handle files bigger then 4gb, i tried to
reformat the sdcard2(30gb) to ext4. first i had installed "Paragon exFAT, NTFS & HFS+" driver on my android device.
i used the tool called "MiniTool Partition Wizard Home Edition" for windows 7 to format ext4 to sdcard2(30gb).
The Drive disappeared and after unplug the cable, android reports about a damaged sd card.
i started "Paragon exFAT, NTFS & HFS+" to re-scan devices but it didnt shown. its maybe possible that my device can native use ext4, i am not sure. then i uninstalled "Paragon exFAT, NTFS & HFS+" and tested "[root] Ntfs Mounter", also no mount luck.
now i uninstalled "[root] Ntfs Mounter" and tried to fix/reformat the damaged sdcard over the notification suggestion.
the build in option failed to restore the regular fat32 partition.
for now my target is to restore the default fat32 to get all working as before.
busybox is installed and i have basics in terminal linux but i struck now how to identify the right device, delete the prober partition.
please advice me to fix it. i think parted will help.
here are some informations:
