MK-5 SD Card capacity Using Linux

[SHEEPMAN!]

So this is the 64?

Good show, thanks for reporting back.

It seems you like navigatrix.

[plateaugame]

Yep, the 64GB.

As far as Navigatrix, I don't have a lot to compare it to, but yeah it does everything I need it to.

Got it working. All I needed to do is format the SDXC card as ext4 using the Navigatrix/linux GParted utility.

My CF-30 dual boots Win7 and Ubuntu and the 64GB SDXC card is readable by either. I formatted the card with exFAT using the program I referenced earlier.

Just ran across this thread/post, should be helpful too.

Well it is not a limitation of the OS, I am running Ubuntu 14.04 x64 on a CF-30 Mk2 and I have a 64GB XCHD card in it. I am using FUSE/ ExFAT with it. See: https://code.google.com/p/exfat/

ok, I'm still messing with this. Do you have any instructional links that don't require a google login?

And here's a newby question.... how do I change permissions so that the SD/media device is open for writing all the time?

I heard some yelling!

And here's a newby question.... how do I change permissions so that the SD/media device is open for writing all the time?

That depends, and it's not such a newby question since I consider this problem a bug or a distribution flaw in configuration. I see you're using Navigatrix which I believe is based on Ubuntu. Is your vfat sdcard or USB drive automatically mounting when you plug it in? If so, type these to see if your distro is using polkit for automounting and show us the output of each command.

Code: Select all

ps -ef | grep polkitd
sudo ls -l /etc/polkit-1/*
grep plugdev /etc/group

I'd have to look up how it's done on your distro but this is more or less how it used to be done on mine, before they fixed it:

[plateaugame]

Yes I believe it is automounting, if I understand the term correctly. But the device/media is never open for write access. I have to open it up at the command line with sudo chmod 777 . And that is _all the time_. If I unplug the SC card and plug it back in the write access is gone.

Before your response came in I found this documentation:
https://wiki.archlinux.org/index.php/Ud ... figuration

I added my user to the "backup" group.
Created this file:
/etc/polkit-1/localauthority.conf.d/50-udisks.rules

..with this content:

trav@traveler:/etc/polkit-1/localauthority.conf.d$ cat 50-udisks.rules
polkit.addRule(function(action, subject) {
var YES = polkit.Result.YES;
var permission = {
// only required for udisks1:
"org.freedesktop.udisks.filesystem-mount": YES,
"org.freedesktop.udisks.filesystem-mount-system-internal": YES,
"org.freedesktop.udisks.luks-unlock": YES,
"org.freedesktop.udisks.drive-eject": YES,
"org.freedesktop.udisks.drive-detach": YES,
// only required for udisks2:
"org.freedesktop.udisks2.filesystem-mount": YES,
"org.freedesktop.udisks2.filesystem-mount-system": YES,
"org.freedesktop.udisks2.encrypted-unlock": YES,
"org.freedesktop.udisks2.eject-media": YES,
"org.freedesktop.udisks2.power-off-drive": YES
};
if (subject.isInGroup("backup")) {
return permission[action.id];
}
});

I then observed no change in behavior at all, and that I really had no idea what I was doing, and decided to give up (keep chmod 777 constantly) until I got more information.

So in that context...

The Automount is a small problem. Every time I boot in Ubuntu it will start in it's own widow. I just close it and all is good, like I said, a small problem.
