| Make sure to move the switch up on the side of the SD card to disable write-protected mode. |
when I mount a mp3 player fat32 disk, it shows an error like this
mount_msdos: Unsupported sector size (0)
This worked for me before, but it's not working for me today. I presume the difference is the M1 Mac.
sudo mount -w -t msdos /dev/$IDENTIFIER /Volumes/$NAME
mount_msdos: Unsupported sector size (98)
mount: /Volumes/HASSFAT failed with 71
@jdjasperson Can I suggest you edit 4. to be sudo mount -w -t msdos /dev/$IDENTIFIER /Volumes/$NAME.
I was able to edit the file using a Windows VM on Parallels (ARM).
BrianHenryIE i'm getting the exact error 71 with an i7 mbp ! it's not related to M1
by the way i'm stuck in this step :
sudo mount -w -t msdos /dev/disk2s3 /Volumes/data
mount_msdos: /dev/disk2s3 on /Volumes/data: Permission denied
mount: /Volumes/data failed with 71
@mohamed-ea @BrianHenryIE seems like this is a common issue now, I solved it on my case.
I was getting:
$ sudo mount -w -t msdos /dev/disk6 /Volumes/fat
mount_msdos: Unsupported sector size (0)
mount: /Volumes/fat failed with 71
The problem is because we were trying to either mount the disk or the wrong partition, make sure you are mounting the correct partition on your disk
does not work for me on an m1 mac,
mount_msdos: /dev/disk4: Operation not permitted
mount: /Volumes/nrf failed with 71
Hi guys,
New here - signed up to respond to this thread.
I was having difficulties mounting an SD card with the process outlined above - kept getting permission denied or read-only access.
Followed the steps, tried to create a new folder in Volumes and mount to that, etc - no luck and was beginning to pull out my hair!
I came across this video on YouTube from 2013 - I almost dismissed it at first because the solution seemed too good to be true - alas! when I tried it, my SD card mounted with full write permission no problem, no playing with custom mount points, etc.

Anyway - I thought I'd leave this here for anyone who might still be having a permission denied issue when trying to mount an SD card with write permission. Hope it helps for some of you!
