Mac Book can't read CR2 Files

[AlysonH]

"The disk you inserted was not readable by this computer" Option to Initialize, Ignore or Eject



A couple days ago, I plugged my card reader into my MacBookPro and got this message. The card reads as it always has in the camera and I've tried a host of different cards to see if that specific card was malfunctioning. I've restarted countless times, tried downloading Lightroom and a couple other programs and still nothing. I have no idea how to resolve this situation, I'm hoping someone on the forum has got some advice. I'm planning another shoot so sooner rather than later.

.CR2 are canon raw files. copy them from your card and use lightroom to open them. your mac can't do anything with them, so open them through lightroom or use canon's software called DPP.

That's just it .the comp doesn't see any files and my cards aren't registering so I cant get to the files at all. Can't even see them. Thoughts?

New card reader. They can go bad.

I've moved this from the Articles forum, as this is a better placed to possibly get more feedback. Good luck!

Can you leave the card in the camera and tether directly from the camera to the computer?

I tried that as well. Got met with the same response. However previously loaded cr2 files are functioning normally, the camera cn red the cards with no problem and the files can load to other comps. I don't recall doing any updates recently either.

If the card works on other computers and on the camera, I think it's safe to say that the card is good... When you normally remove the card from your computer, do you always select the 'safely remove drive' (or whatever the actual text is) option, or do you just pull it out?

The only thing I can think is that the card was removed before it was unmounted, and so the computer thinks it's still there. To fix it (if that's the problem) you would have to open a terminal and manually unmount the drive in question.

Does the computer show the card when you insert it, or is it like it isn't even there?

If it shows it, then the problem is not the unmount thing.

Yeh I always opt to eject safely cause I don't want to damage anything. But i'll look into the terminal to check. I've never had to do anything with terminal before though. Any pointers?

do you know unix?

 

[Josh66]

If you always safely remove the drive, the mount/unmount thing probably isn't your problem...

But - if you want to check in the terminal, type mount to list mounted devices. Type lsusb to list USB devices. Do that and see if it shows the card already being there. I think it would probably be on the USB one... It would probably say the brand name of the card - it would show a Sandisk device, for example.

For example, this is my output of lsusb:

This is what it shows when I plug in a thumb drive:

That last entry, Bus 002 Device 007 is my thumb drive.


I run Linux, not Mac - but as far as the terminal goes, it's all the same.

 

[AlysonH]

No I've never tried Unix, but I'll give it a go. Looking into the terminal now .

 

[AlysonH]

TPF Junkie , is that PC speech? What I'm seeing on my screen looks nothing like that .

 

[AlysonH]

Hey guys, this is what I'm seeing from my terminal. Looks like gibberish to me, but I don't see anything (or dont know what I'm looking for ) to correct. I also went into the forum with the card plugged in, no difference.
