Hi,
the bearded man brought the D7200 to me.

I can acces the camera via usb and gphoto2

However,I would prefer to copy my shoots from the SD-Card directly.

If I plug it in, it get (via dmesg):

Code:

The SD-Card works perfectly fine on the nikon or at a SD-Card-Reader for my ipad.

check your support for file systems and other settings in your kernel.
Check your usb settings for xhci or what it is called. check usb section, staging section and other sections



check if there is someone else already on the net using that camera on gnu linux.

Well thats not relevant. And shows you have not really understood how it works.

The issue is

Compuer => cable => camera => sd-card

not

computer => sdcard

...

how nikon writes to the sdcard is another issue. they could use anything however they like. i would not be surprised when there are errors in the file systems because of bad firmware of that camera.

...

to make it clear: your issue is the connection from your computer + cable to the camera. Also bear in mind bad usb connector on the mainboard, bad usb cable, bad camera socket, bad firmware of the camera ...

I had similar error when I used a USB cardreader with micro-SD adapter. Turned out the adapter wasn't up to the task. What size is your SD card?

Hi,
Youre right i did not mention that other sd-cards work fine with my gentoo-desktop, even 32gb micro-sd via adapter. This card in question has 32gb and is a normal sized SD.
Does Nikon use anything different as FAT?

To be clear: i'm trying to read the sdcard directly. For that, i take it out of the camera nd plug it into my pc. This leads to the above quoted message.

Error sources i can think of:
1. Card is too new for my pc's card reader
2. nikon uses non-standard file system where my kernel isnt stuffed for

1. i can only hope that standardization takes care of that.it is a 32gb lexar 633x 95MB/s

2. i have no sources that claim anything other than FAT

What else could it be?

Look at dmesg, it cannot read the raw device. Some sort of hardware issue. You may need to get a USB card reader for this one.

Yes, I installed fuse-exfat and exfat-utils, but the problem persists. So it really seems to be an issue with an outdated cardreader module of my box here.

Hi walls..

Sorry if this is a bit obvious, but.. Have you tried formatting the SD card using your existing SD card reader, then inserting it into the camera? I'd do the following (assuming your SD card is at sdc)

Be *real* careful that you don't end up formatting one of your hard drives! - easiest way is to open an xterm and do a "tail -n 200 -f /var/log/messages", then plug the card in while watching the messages. If you get an error here then it's game over, as it's likely the SD card and reader aren't compatible - but post the messages if you're not sure.

Then:
"dd if=/dev/zero of=/dev/sdc bs=1M count=20" - that will zero out the first few hundred sectors on the SD card
"fdisk /dev/sdc" - create a single partition sdc1 of type "b" which is Windoze FAT32 (ask if you need more help with fdisk)
"mkfs.vfat -v /dev/sdc1" - that will create a FAT32 filesystem on the SD card.

If you plug the card into the Nikon it *should* recognise the card - well, anyway, it works with my 3 year old Nikon.

Let us know how you get on..

Best Regards,

Rob.

My bad! I didn't look at the dmesg output carefully enough :oops: That's game over for the SD card/reader combination. So, as the SD card itself is working fine with other gear it looks like you need to buy a new SD card reader. Luckily they are dirt cheap.
