USB Interactions Query

I use a Canon 7d MkII for my photography. This uses two cards - an SD card and a Compact Flash card. When I plug in the SD card to my Swift 3 running Win 11 it cannot see it. However when I plug in the Complact Flash it sees it without issue. This causes a problem when I'm out in the field as I tend to store movie footage on the CF and stills on the SD which means that I can't get to the stills until I get back to my desktop. Any ideas why this happens?

I should add that neither the USB3 ports nor the Thunderbolt work with the SD card.

TIA - Dodger

    It's the format of the SD card or your card reader that the Swift 3 has a problem with and that is why the sd card is not being detected or the sd card is faulty. The best sd cards for your Canon EOS 7D MkII cameras with its storage of 1x CF and 1x SD (SD/SDHC/SDXC compatible cards, is to use a top brand like Lexar Professional 1066x CF CompactFlash Card or the SanDisk Extreme Pro 160MB/s sd cards and also use a top card reader like the Lexar Professional Workflow CFR1 CompactFlash CF Card Reader USB 3.0 and you won’t have any problems with Win-10/11, as it could be all of these factors why your sd card is not being detected.

    I use SanDisk Extreme Pro cards although neither of my readers are top of the range. The SD card seems OK as I can access it using my desktop and an older laptop. I'll try formating it again and see what happens.

    What size is the SD card? IIRC Canon uses either FAT32 or exFAT depending on card size. You might try formatting an SD card with the Swift, then using it in the Canon without a separate format. If that works we're likely looking at a software issue. If the card doesn't format on the Swift it's more likely hardware. I can look at specs for more detail on the Swift 3, but I need to know just which Swift 3 you have, there have been a bunch of them over the years and locales. The full model number should be something like SF3xx-xxx-xxxx and it's usually on the same sticker as the serial number.

    Many thanks for your help.

    Riiight! I've had a bit more of a play with this.

    I've tried both 32 and 64Gb cards. They're both formatted as exFAT. I don't think that they're the problem.

    I tried a 64Gb USB 3.0 thumb drive in the USB A slots and it worked fine. I then tried the same drive into the USB C slot via my adaptor and nothing...I tried another adaptor and nothing.

    I then checked that the cards worked in the reader that I use on my desktop. They worked without issue. So I crawled about under my desk - the lead for the reader goes into the back of the tower - and took the reader and lead to my laptop. I tried it in both the USB A and USB C slots and could read the cards in both. It looks like the problem is an issue with the adaptors that I'm using with the laptop not the ports on the laptop or the cards.

    I've ordered a new card reader from Amazon that will plug directly into both USB A and C slots. I'll let you know how I get on.

    FYI - It's a pretty new Swift 3 - that's why I've just encountered the problem. The model number is SF314-811-7293.

    I have received three different devices lately that come with USB-C to USB-A adapters and all three adapters don't work. I left appropriate reviews on each. :) I wonder if it's a batch of generic adapters the vendors are using, of if there's something I don't understand about how the adapters should work...

    "I wonder if it's a batch of generic adapters the vendors are using"

    Maybe but the adaptors that I was using are pretty old so I don't think they'd be part of the same faulty batch.

    Good news though. I've bought a new card reader and that works fine. So problem solved. I'm not going to bother with a post mortum as life's to short. :)
