How to reformat sd memory card on mac

It should be regularly blown out with compressed air. Here's a another tip that most people have no clue about. On a Mac you can create your own unique icon for each card that will appear on the desktop when a particular card is used. Could come in handy for pros using and reading from multiple cards at the same time.

Same here, across two macbook pros, an imac, and a mac mini I've never had an issue with the built-in card reader.

As you say, probably debris getting in the macbook pro, or possibly it being knocked around. I had an issue with the SD reader on my Pro. Somewhere someone suggested I simply blow into the slot forcefully, which I did. Presto, problem solved. Seems it can accumulate dust on the contacts. Now I'm using the Pro, so everything's external.

Unless something is air tight dust will work its way in there. In the future though a can of compressed air works best. They are also crucial for cleaning the interior. For my iMac, for example, I stick the tube up the front air intake and the dust goes out the back from the single big fan. I also blow the big fan while stationary and while spun up to max speed. The contacts on the cards themselves can also accumulate dirt residue. I currently have 3 macs with SD card readers built in, Ive had issues with all 3 since they were brand new.

It could be dust problems, though third party ones never seem to accumulate dust. One tip I've heard repeated over the years is to always format your card in camera, and not through your computer software following import. I had an issue in the past where the camera was having trouble writing to the card and it was only after I reformatted it in camera that it began to work normally again.

Since then my approach to memory cards has been.. That's a good strategy but honestly, even the cheapest eBay card readers should be just as reliable. Sure they are more likely to physically break but even SanDisk and Lexar don't mention the chipset they use.

If there is going to be a hardware write error, that's the failure point. A couple things I've learned.

The first is to avoid deleting shots in the camera because this makes card write errors more likely. The cause is that it opens gaps in the write locations, which the camera fills in with subsequent shots. This means an image's data can end up in multiple locations on the card. It's better to copy to your computer, then delete rejects in Lightroom or Bridge. Having had cards crash on me twice, I now shoot backup configuration, with the same RAW file writing to both cards, and to the computer as well when I shoot tethered.

With today's high capacity cards, I don't find this much of a handicap at all -- I have to swap cards more often, but still have RAW frames before I have to, so it's not that big a deal for most types of shooting. It has saved me a couple of times now. Last, the advice to clear your cards by reformatting in camera after confirming you have the images and backing them up is spot on.

This eliminates a host of potential problems. To add to this, reformat whenever you put a card in a different camera -- even the same make and model. Considering photos are almost universally considered one of our most valuable possessions, I find it ridiculous that all cameras do not offer two card writing in case one card fails. In fact formatting in camera will not "delete" the content" - not for speed reasons as with spinning disks , but to not wear down the flash memory. This means obviously that you shouldn't format the card that often, to avoid overwriting the same blocks over and over again.

Personally, I'm aiming to retire cards long before they approach the write limit of the SSD. About , if you are curious. But ya overall, good call. Sorry to say, but you should investigate further. The failure rate of modern SSDs is actually just times their capacity - which is enough for SSDs but SD cards get easily filled up plenty of times. But true, if you retire them every 2 years your probably fine :. Never had a card problem when shooting professionally luckily , but I've trashed 2 expensive SD cards, and some family holiday memories by ejecting them from the camera slot when it was still powered on.

Both on Fuji X-Series cameras incidentally. CF cards seem a bit more robust in this respect. Switch the power off before ejecting. You may want to check your facts here. Using Computer based scanning tools or deleting cards on a computer is just horrible advice. Format them in your camera. Sure it is. All you have to do is accidentally click on the card itself as the destination when importing. If you do that the images then remain on the card and if you "delete" them in Lightroom, they are trashed on the card. You may think this is unlikely but I've seen it happen many times.

I think people get destination confused and sometimes think it means where they are importing from. I helped someone with this problem just this week inspiration for the article. She had accidentally deleted an entire shoot this way and I found all the images in the card's "trashes" directory. I never said to delete or reformat the card on the computer. Also how would you scan a card or repair a card if not on a computer?

Cameras don't have built in disk utility like tools.

The Solution

Thing thats been happening lately for me is, when I import my I get the "image can't be displayed" or something like that. I'll have to restart and than try again. Not sure what that means or if anyone else has seen that occur? I use it to format my SD cards, but I don't format my cards as frequently as professions would do. Years ago first digital camera I had some funky Sandisk cards. Since avoiding Sandisk the only times I lost images is the two times I lost the cards.

But I have lost 4 or 5 hard drives in that time. Disk Utility doesn't do anything.

It checks file system consistency. Just format the card in camera and don't stress about it.

Turn off the camera and insert the SD card into the proper slot. Turn on the camera. On the camera, select Menu. On the camera, select OK. Wait while the camera formats the SD card. It may take a few minutes to format the card. When the SD card is formatted, turn off the camera. In the App list, tap Settings. Tap Storage. Tap the SD card name.
