Of 5 new 64G SD cards, 4 wrote ok, 1 fails with 'Error 5: Permission Denied' ??

Asked by Greg Gibbons

This failure repeated reliably, after re-seating the card, formatting, etc. Surely there is a way to override whatever 'permission' is being denied ? This is one of 5 new in package Patriot LX Series 64GB SD cards - the rest wrote ok first time, and when used in the destination Raspberry Pi indeed worked correctly as clones of the originally configured SD card for that device. Cannot see how this is operator error; perhaps bad hardware, but seems more likely to be a different image on the card from the mfr vs the other four supposedly identical cards.

Any help available?

This is a known issue with Windows taking control of the device before we can. Purely a timing issue.

Things to try: if you can, make sure there is nothing on the SD to begin with. No hidden files, nothing. Try reformatting it. Then remove it, and reinstall it (before launching Win32DiskImager).

Hopefully this issue will be resolved if/when I can get around to adding full SD support (leave it to Microsoft to use a completely different API than what they use for USB even though the devices are programmatically the same).

Got suggested solution immediately from Tobin Davis, many thanks. Partial success: I did format the device (when inserted it opens several droves apparently on the SD card. ) I formatted each of them, dismounted the SD card, reinserted it, then opened Win32DiskImager. This time it ran to completion, but very fast compared to the successful prior actions with the first 4 cards.

When installed in the RPi, got error 'Error mounting settings partition, seems corrupt, reformat?'. Yes. NOOBS initializing.. Noobs build Oct 10 2018 offered raspian, accepted, warned installation will overwrite everything, went ahead. I bet it is now a NOOBS device without all our configuration and files. It proceeded through the basic setup (choosing country, timezone etc.).

So apparently it is now a newly setup RPi card, but without all the local downloads and configuration info.

Thank you for the help, much appreciated
