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.

  • Where did you first format it? macOS can't read or write Linux ExtFS natively, you need a 3rd party add-in, Paragon etc. Note that First Aid only looked at the FAT partition. Commented Sep 12, 2023 at 16:49
  • I formatted it using Raspberry PI Imager. Unfortunately it will not let me do it again as it says it was write protected. I don't really care what is on this SD card right now. I would be down to wipe everything on it and start fresh. Commented Sep 12, 2023 at 16:52
  • If it won't format on anything, it's probably had a write error, which would push the firmware to lock itself protectively. This is, to all intents & purposes, irreversible. See superuser.com/questions/1125282/… Commented Sep 12, 2023 at 16:54
