Hi,

 

I tried to save the images on my CF Card [SanDisk Extreme 64 GB 120 MB/s UDMA 7] from a D810 on to a MacBook Pro and subsequently to a Windows 10 PC, using a USB 3 Card Reader. 

 

On the MacBook Pro the error message is that the Card cannot be read as it is not formatted for a MAC. 

 

When I use the same CF Card and Card Reader on the PC, the error message is the card is not formatted.  In both cases I am asked if I wish to format the card.

 

I would appreciate any help from the forum on how I can get the images off the CF card on to either the MacBook Pro or the Windows PC?

 

Thank you

As the Mac can read the most common non-Mac-formats (FAT, exFAT and NTFS), it would be interesting to know, what the actual format is.

 

You can check with "disk utility" in macOS/OS X.

 

As a work around, you might try connecting the camera directly with a USB cable to the computer.

Unfortunately, this sounds like a scrambled file allocation table. If using the camera as a card reader doesn't work, you could try to get your hands on RescuePRO. This application will read the surface directly, bypassing the FAT and usually works to rescue information from a scrambled card. It might, of course, be a defective card reader as well.

 

Was the card formatted in the camera or using a card reader and computer?

I think that, assuming the images are readable in camera, I would try Malice's idea and connect the camera directly. If the images all transfer completely, I would probably be inclined to at least temporarily retire the card. However, I wouldn't rush to reformat it until I was absolutely sure that all the transferred images were serviceable and backed up to a secondary location. 

 

Having said that I would add that I'm immediately suspicious of any card that is this problematic.

My thanks to Ron, Merck_61 and Malice for their suggestions.

Problem solved.

i had managed to bend the pins at both ends of the card reader slot, when I inserted the card for the first time.

Once the pins had been "straightened" I was able to gently insert the card into the reader and access the images on both the PC and the Mac. 😡

Thank you all.
