Can't wipe SD card via diskutil or disk utility. Could it be broken?

I am using a MicroSD card to program my Raspberry Pi with. I was recommended the AEGO Micro SD Card 32GB Mini sd Card card. However at this point I am wondering if I have broken it. Here's what I have tried - Disk Utility - First Aid on Generic Storage Device Media -> Operation successful - Repartition on Generic Storage Device Media -> Greyed Out - Erase on Generic Storage Device Media -> A writable disk is required -69772 - First aid on system boot -> successful see results below - Erase on system boot -> it tries to unmount disk Couldnt modify partion map -69874 - Terminal - diskutil erase -> (newfs). You cannot erase the boot disk. Ownership of the affected disk is required. Example: diskutil eraseDisk JHFS+ UntitledUFS disk3 - diskutil disableOwnership /dev/disk6 -> Error encountered disabling user/group ownership: A disk with a mount point is required (-69854) Is there any way to recover from the state I got the SD in? Or is it potentially just broken now? How can I tell? I have checked and the physical write lock is in the correct position. Here is diskutil list /dev/disk6 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *32.0 GB disk6 1: Windows_FAT_32 system-boot 268.4 MB disk6s1 2: Linux 31.7 GB disk6s2 Here is the first aid on system boot Running First Aid on “system-boot” (disk6s1) Checking file system and repairing if necessary and if possible. Volume was successfully unmounted. Performing fsck_msdos -y /dev/rdisk6s1 ** /dev/rdisk6s1 (NO WRITE) ** Phase 1 - Preparing FAT ** Phase 2 - Checking Directories ** Phase 3 - Checking for Orphan Clusters 430 files, 185612 KiB free (371225 clusters) File system check exit code is 0. Restoring the original state found as mounted. Operation successful.
