Thanks for the clarification, Jim. That's fine. I'll have to get myself a micro-SD card adapter for when that time comes.
I've not had much success at all reading Amiga-formatted 5¼-inch disks with the SCP today. I've had no joy whatsoever reading disks in splice mode while ignoring the index (the source grid filled with orange boxes). I tried that because of the uncertainty about where each track starts on Amiga disks, but the resulting flux (.scp) images are just rubbish, and when they're converted to ADF images, the source grid boxes are all red. The destination grid is filled with blue boxes, but the disk images are all filled with zeroes.
Using index mode with the drive index signal required to produce flux images seems to give much more reliable reading (the source grid filled with blue boxes), but when converting them to ADF images, the source grid is mainly filled with red boxes and just a few yellow, while the destination grid is again filled with blue boxes. This time, the resulting ADF images are mostly filled with zeroes and a mixture of valid and corrupt data in the tracks corresponding to the yellow source grid boxes.
I'll try some 3½-inch Amiga- and PC-formatted disks next, just to see if I can get anything working at all.
In the meantime, could you clarify the meaning of the coloured boxes in the disk copier/imager grids for me, please? It seems to me that red, orange and yellow boxes indicate failed reads with one or more bad sectors, and blue boxes indicate good reads or writes, though the written data can never be valid if the original read was bad.
