Quick question, because I just can't find it on google. I have a 64gb micro Sd card (exFAT) which I want to split into two partitions. But it just won't work.

Basic Knowledge of SD Card You May Want to Know. SD card is a type of memory card featured with large capacity, high cost-effective, small volume, low power consumption and simple interface. Just because of that, SD card is widely used in portable devices, such as digital camera, MP3 players, mobile phones and some game consoles.

The option to partition it is greyed out in Disk Utility, and I can't find a solution on google anywhere. The card needs to say in the exFAT format because I want to continue using it in my Sony camera. The reason it needs to be split in 2 (rather than just leave the photos in a separate folder on the card) is because Lightroom doesn't let me 'add' photos from the card to the Lightroom library since it recognizes it as a card that's used in a camera. So my plan is: take photos, save them on the card (I hope my camera will always 'pick' the right partition the save them on.) And every time I put the card in my MacBook, I'll transfer the photos from one partition to the other before loading them into Lightroom. It may seem cumbersome, but it really isn't, since a big card doesn't make me carry around a external hard drive. And saving them on my Mac isn't a great deal too with a 128gb ssd.

I've looked into the Lightroom problem, which doesn't let me add photos from a sd card. It works perfectly great when they are on a external drive or usb stick. But Lightroom recognizes the camera folder structure and blocks you from importing from the card. So, I hope anyone knows whats up, why can't I just partition this card? You need to select the item that says 'Apple SD Card R.'

That item represents the SD card as a whole. The screenshot shows you've selected 'Sony NEX-6', which is a partition on the card. It's the only partition, but it's still a partition. Since you can't partition a partition, you can't get there from here. After getting the card partitioned, I recommend testing it thoroughly in the camera.

By putting everything on one card, any errors will likely corrupt the whole card, and boom go all the photos on all partitions. I think your problem with LR is that you should not be trying to 'ADD' when importing from an SD card. Use COPY instead. When you use ADD, LR does not copy or move the files. It adds a reference to them in the library but the reference refers back to the SD card, not to your hard drive.

If you then put the card back in your camera and format it, all the pictures are gone because they are not moved to the HD. It is to prevent that error that LR prevents you from using the ADD option in the import dialog box when it recognizes a card came from a camera. If you use the COPY option, LR will copy the files from the SD card onto your hard drive, which is what you want. Try that first before you partition your SD card.
