I use a Sandisk 256 gb MicroSD card in my AIO-5 Lite. Today I had to remove it to copy the contents of the dash cams to my Network Storage (a Synology NAS).

When I finished I put the card back into the AIO.

I then went to Storage to check that it was properly inserted. It was.

I was then presented with a screen that said that it was "used" and required formatting, which I did.

I then got a screen saying that it was testing it for speed read/write. It returned a message saying that it wasn't fast enough.

Please see the attached photos of what I saw.

Please note: this card was removed from the AIO, put into a Windows PC and the files copied direct to the NAS. No editing of the MicroSD card was done (no file deletion, etc.).

1. Why did it say, "used".

2. Why does it tell me that it's too slow given that it's been working fine. It's a Sandisk Extreme, too with 190 Mb/s read and 90 Mb/s write.
