Like the title says, when I attempt to use my new 128gb PNY MicroSD card, I get the message "Card cannot be accessed", where my 16gb sandisk SD still works fine. If I try to format I get the error: "Cannot format change card".

The card works fine with my computer, so at first I thought it was a problem with the formatting. I found a tool and reformatted the drive into FAT32 which my other card is using, however I still got the same error message. Am I doing something wrong?

Update: I tried partitioning the card below 32gb, and I still got the same issues.

Update 2: I borrowed another 128 msd from someone else and the camera works just fine with it. I'm going to check how this drive is formatted.

  • There is a chance the maximum GB for that camera are 64. For example on some powershoot cameras the max is 32 gb. support.usa.canon.com/kb/index?page=content&id=FAQ100296 But I can not find the max for EOS cameras. – Rafael Sep 11 '16 at 23:19
  • Would it possible to partition the drive or limit it to 64 or 32gb to get around this? – Skyler Sep 11 '16 at 23:40

  • Have you tried using the microSD card in a different microSD to SD adapter? – Michael C Sep 12 '16 at 0:56
  • @MichaelClark I only have the one, but I'm assuming it isn't the problem because my computer has no issues with it. – Skyler Sep 12 '16 at 1:12

I have a T3i - the two generations older camera - and it handles 128 GB without issues. That is not a proof, but a strong indication that the T5i would too.

If you google for 128 GB T5i, there are many combo offers that offer a 128 GB card together with the T5i camera.

I would assume that the speed class is insufficient, or the card or converter has an issue - or the camera has an issue.

  • It is just a T5, but I don't know if that would matter. And for clarity, the speed is 85mb/s, The card works with other devices, and the camera works with other cards – Skyler Sep 12 '16 at 1:28
  • ops missed that non existing 'i' - they are offered too, though: ebay.com/itm/… – Aganju Sep 12 '16 at 1:31
  • The OP's "update" makes this question moot; but your info appears to be correct. – Carl Witthoft Sep 12 '16 at 11:41
