-=1D Mark IV Owners Thread! (it's time)

more wonderful birds!!

OK.... a sanity check. I tried to format a SanDisk Extreme Pro 64 GB 95 MB's card in my 1D IV and it won't recognize the card. I formatted it in my 70D and it works fine. I have been using a 32 GB 95 MB's card and it works without issue. Truth be told, I didn't realize I had a 32 GB card in the camera until I ran out of room on it yesterday because I took 1602 photographs with the CF card... and the CF card is 64 GB's, btw.

So, is the card bad or are there GB restrictions on SD cards on the 1D IV? I was sort of shocked when the 64 GB SD card wouldn't format, esp. since as above, the CF card is 64 GB's.

Ok, from what I can glean from DPreview is that all 64GB cards are SDXC and will not work. The 1DIV only works with SDHC cards apparently?

AND, I found this link explaining why.

Jay,

Thanks for your research. I'm in the middle of downloading a ton of photos and it slows my computer down to a crawl.

I'll have Becky use the 64 GB in the 70D she "borrowed" from me.

You're Welcome Kim. And I'm sure Becky will enjoy that card in HER 70D

Relax, I am using a 200 gig SanDisk in my 1DMkiv - all you need to do is to format the card in FAT32 - not exFAT !!!

Those larger cards come in exFAT preformatted, but the Canon camera cannot deal with that format, cannot even format the card.

Long story short, head over here
64bit version http://www.ridgecrop.d​emon.co.uk/guiformat-x64.Exe
32bit version http://www.ridgecrop.d​emon.co.uk/guiformat.e​xe

Format the card and you will be just fine.

Cheers.

Thanks for the info BoKo.

Just use that tool. It will format the card in FAT32. There are other tools out there, but this I have used numerous times without any issue.

Cheers.

If you are wary of using a tool from the internet, then insert the card into your computer (or card reader connected to your computer). Wait for it to show up as a drive. Then right click on the drive and select format. You will have an option to format as FAT32. This works in Windows, anyway. Not sure how to go about it on a Mac.

No, it won't work like that at all.
FAT32 and exFAT are proprietary file formats by Microsoft.

The format functions in Windows depend on the OS version and on 32 or 64 bit of that OS and on the size of the media targeted to format. In other words those criteria will limit what you as the user can actually do.

Your method will fail miserably on every 64 bit OS if the card is larger than 32 gig. In Win10 the windows format tool will not even give you an option.

Trust me....

OK gotcha, and the link. Thanks again.
Looks like a nice utility to have on hand anyway.
