I found that using a low-end adapter was causing the problem. I purchased a new 128GB microSD card with adapter and popped in the cheaper 2GB microSD card to format and it worked like a charm. Copied the "FIR" file and updated the firmware.


The micro-SD cards with adapters are nor recommended for use in Canon DLRSs.  If you check the instruction manuals, nearly all of them state that you can use SD, SDHC, and SDXC cards.  They make no mention of using micro-SD cards.  

 

MicroSD card adapters are notoriously unreliable.  The micro-SD cards should only be used in devices that use them directly, without an adapter.  You should only use the regular, full-size SD cards in your Canon DSLR.  Furthermore, you should always use the camera to perform a "low level format" on any new memory card before first use.

Format the card on your computer wth FAT32.

Load into camera and format again.

Did you know that you cannot format a 128GB card as FAT32?

How Do I Format the Card

http://support-sg.canon-asia.com/contents/SG/EN/8200748800.html

 

When the card is formatted or data is erased, only the file management information is changed. The actual data is not completely erased. Be aware of this when selling or discarding the Usb card. When discarding the card, execute low-level formatting or destroy the card physically to prevent the data from being leaked.

Card may not be compatible with the camera for some reason, maybe it's over the max size the camera can read properly. I don't see a max card size in the documentation for the camera though, maybe try a 2gb card http://support-sg.canon-asia.com/contents/SG/EN/8200748800.html
or try the below article to see if there is any problem with your device or ports

Re: SD card won't format - Cannot format Change card

I'm not sure why people are saying not to use micro SD cards just because Canon doesn't specifically mention them in their manual.  They work great and I've been using one in my 60D for the last couple years without any issues.

 

Good point about the adaptor being a fail point.  Replacing the adaptor solved my problem.  Luckily the adaptors are only around one dollar, so I'll keep a couple extra handy in case I run into that issue again.

 

My adaptor failed after using it heavily for two years.  I've had SD cards last shorter times than that.  Easy and cheap fix.  All of my images were still on the micro SD card and it works fine.  Hope that is helpful for others who are having this issue.

It's a matter of risk reduction. If you're in a photo shoot that really matters, it makes sense to take as little risk as possible. A card failure is not as likely to be obvious at the time as, say, a flash failure. I wouldn't risk a shoot on the performance of a $1 part, and I suspect that most people in this forum feel the same way. If you don't, that's obviously a decision you're free to make.

 

To your first point: The reason we advise people not to use micro SD cards is that we've received more questions and complaints about micro cards not working well than one would expect if they were as good as full-size cards. And if they're not as good as full-size cards, why use them?

I don't understand why people want to use them when Canon does not specifically recommend them in their manual.

Regardless of what others are saying re micro-SD. They are perfectly compatible with any function that requires an SD card. AS for corruption being a problem, a micro SD is no more prone to failure than a standard size SD.  

 

The main cause of failure in SD cards is in handling them. Removing and putting them into something to be read and then returning them to the camera causes wear on the contacts, whether it is an SD card or a micro-adapter with a micro card in it. Leave the card in the camera unless it is necessary to remove it. Use the USB cable to download tour pictures. 

 

All SD cards have a very thin gold plate on their contacts. (measured in um) That gold makes for better connectivity and retards corrosion. It wears off quickly with any friction. Any electronic device that has gold plated contacts is not designed to be removed and reinserted repeatedly. Those contacts are extremely thin metal, usually a copper-nickel alloy. They too can wear and lose their adhesion. (https://www.pcmech.com/article/signs-sd-card-failure/)

 

Any card (or adapter) that has a worn contact is almost guaranteed to have been removed and replaced repeatedly. Replacing any card that has failed with another card will fix the problem, REGARDLESS OF WHY THE ORIGINAL CARD FAILED. That is not an indication that the physical size of the card was the problem.

 

The reason that Canon makes no reference to either Standard SD or Micro SD is because there is no difference other than the physical size. There are differences in how the cards write (or store) their data. That is seen in their speed rating and class labels. Then there are the high capacity, SDHC, extended capacity cards, SDXC and ultra high speed write UHS. (And video VHS) But none of those are a problem for Canon cameras and the manuals reflect that. Any SDHC (32 GB or less) or SDXC card (64 GB +) card is acceptable. (NOTE: as regular SD is 2 GB or less, they fill up quick so I personally do not recommend them but they will work very well)

 

***

NOW, having written all that, the caveat. Any manufacturer belonging to the SD Association must adhere to their standards. But there are a lot of counterfeit cards out there. While a card built to Association Standards has Read / Write of a million times, counterfeit card don't. If your new card is corrupted, start thinking you were burned with a counterfeit. Buying from eBay or the gray market hucksters and the chances are much greater you will get garbage. Buying a card from the big internet camera stores (B&H, KEH, Henry's, etc), or Walmart, Best Buy, and even your local camera store are much safer.
