Aperture won't recognise SD card

I have got the same trouble.

Sometimes it works fine: Aperture recognises my sd card in 10 seconds after I inserted it.

But usualy it takes 2 minutes or more.

Sometimes it can help, if you unmount and insert the sd card again.

The simpliest way is to drag images into Aperture, but if you want to import only a part of images from the sd card, or you have already imported some of images and don't want import all images again, you lose 😟

And, if I import images of many different days into different projects, Aperture can not delete all of imported images at the end.

It's uncool.

I'm having this same issue, but worse: iPhone recognizes the SD card and imports from it fine, but Aperture is blind to the card. Frustrating.

IMO it is a very bad idea to let Aperture or any other images management app have direct access to one's not-yet-backed-up originals. Sometimes there are just "anomalies" such as you are experiencing, but worse things can happen.

Suggested workflow steps:

• Use a FW card reader or MBP slot to copy to a file folder on the SSD or hard drive. With fast camera cards copy times are quick, but cheap slow cards can slow this step down a lot.

• Eject and physically disconnect the card reader.

• Back up that file folder on external drive(s).

• Only after backup is complete and verified, reformat the camera card in-camera.

• Import images into Aperture from the file folder on the SSD or hard drive.

Have you checked that when you first import any pictures from the card that the 'Eject card' box is unchecked?

Took me ages to realise that was the reason that Aperture could 'see' the card.
