Next time just remove all those partitions and format it in the device. Now keep it there.
If anyone recommends what you noted, take it up with them to tell you how to fix it.
I am using windows 7 and before partitioning my mobile's (Samsung Galaxy S7) SD card I did backup to all folders that were installed on it and those apps were moved by AppMgr III (App 2 SD) .
Then I partitioned the SD card using the utility called "Mini Tool Partition" as per the snapshot below (SD card named as Disk2 not 1 and size is 32 GB)
I created 3 partitions as per some online recommendation and as below :
8 GB Fat32
16 GB Ext2
8 GB Swap
Using my laptop slot that is designated to SD card I wanted to copy the backup to the partition Ext2 which utility will let me do that ? because when I copied them back to the SD card Fat32 partition phone was not able to read those apps !!!
So far I tried ext2explore and Ext2Fsd-0.68 with no joy
