If not then you can mount the disk on another system and copy the required files to the card. Your mileage will vary according to the type of filesystems you have on your SD card. For example, if ext4 then Windows will not see them. So another Linux system is ideal, you could use a 'Live CD' on any Windows systems, mount its HDD, mount the SD card and then copy via drag and drop.

You modify the filesystems to be Windows compatible if it were more convenient to you. Depends on your overall goals in your project.

You will probably copy the files into the pi user account i.e into /home/pi or a sub-directory you have created within that location (say something like /home/pi/audio). You should how no problem finding that via a 'Live CD' file browser on the SD mount.

With a network connection, WiFi is cheap and usually trouble free to set up nowadays, then simply use secure copy (scp from the ssh stable). There are a variety of ways of getting this functionality, my solution has always been to install Cygwin on my Windows laptop(s). This will provide the full Linux experience from the command line, well as much as you want.

Hope this helps.

How is your SD card partitioned?

Code: Select all

sudo fdisk -l

on your Pi will show you.
On inserting a Pi SD card into my Linux box, running Ubuntu, I would see several new mount-points. The one you have show is what /boot. As I've configured mine a second one will be the /home directories containing the pi accounts filesystem. I would then be in a position to drag'n'drop files as you appear to want. But of course mine is Linux throughout so I've not much worry about the various filesystems, it all is consistent and inter-working is no issue.

http://blog.applegrew.com/2011/12/acces ... lion-10-7/ says that ext2/3 filesystems are supported, but I've seen ext4 requires some commercial software. Maybe someone on the forum can contribute here. But once you have a filesystem your Mac can see then you should be able to achieve your result.

If you can determine the SD configuration, idnetifiy your version of Mac OS, then we can go from there I'm sure.

Meanwhile back to the rugby!

Look at the content of /etc/fstab on your Pi, it will show you type of filesystem. On one of my system:

Code: Select all

[b]cat /etc/fstab[/b]
proc            /proc           proc    defaults          0       0
/dev/mmcblk0p1  /boot           vfat    defaults          0       2
/dev/mmcblk0p2  /               ext4    defaults,noatime  0       1

So I have ext4 and I daresay yours is the same. So that ext4 is going to be a source of aggravation by the look of it.

You can look at the gparted tool (or parted on the command line). It is run under sudo since there is potential to run your system, so be careful. Its fairly good in protecting you form yourself! Basically you need to re-format the ext4 partition to something OS X can recognise. This will destroy any data on this existing partition, so you will have to tread carefully.

Is all ouf your SD used do you know? If not, you could create a partition of the OS X friendly type. Put the SD card in your Mac to verify it can be read. You could create an audio folder on your new partition and copy your files into it. Then put if back in the Pi, login and make sure that you can mount the new partition by adding to the existing /etc/fstab file and then access its data. One can then muck about to make it all a little saner in terms of SD usage but you at least know it can be made to work the way you want!

If all the SD card is used you can still mangle it but it just (even) more convoluted.

Hope I've not confused you!

Search these forums for any input, if nothing else you will gain some background. For example
http://www.raspberrypi.org/phpBB3/viewt ... ms#p278960 fills in a bit mor einfo for me.

Googling may also help. For example http://forums.macrumors.com/showthread.php?t=1498072 lists some alternatives.

Basically you have an SD card with vfat/fat32 and an ext4 partitions. You've seen that your Mac can read the vfat one so one obvious thing would be to make the second one vfat too. You didn't say whether you were employing the full capaciaty of the card? If you run parted you can list the details, in my case, I sudo parted and run the print command:

Code: Select all

sudo parted
GNU Parted 2.3
Using /dev/mmcblk0
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print
Model: SD SU16G (sd/mmc)
Disk /dev/mmcblk0: 15.9GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End     Size    Type     File system  Flags
 1      4194kB  62.9MB  58.7MB  primary  fat16        lba
 2      62.9MB  15.9GB  15.9GB  primary  ext4

and it will show you whether there is a chunk of unformatted space. In my case, the 16Mb card is used entirely (add up the sizes!). Now parted is a tool where you can re-size the partitions, so if it were me, I'd look to shrink #2 to half its size. Then, in the 8Gb of free space now available, create a new #3 partition and format it as fat32. I would then get the Mac and Pi to access that new partition, so as its stands the Mac would be able to read only 2 out of the 3 partitions, while the Pi would see all 3. parted has a help command, and there are numerous tutorials online.

Typically , this works like this :

Code: Select all

mkdir /mnt/transfer
mount /dev/mmcblk0p3 /mnt/transfer
cd /mnt/transfer

Now you can use the third partition
(the directory "transfer" on your Pi and write files to it.
Mac OS X , Windows and Ubuntu "auto-mount" partitions
(and might do this with this third partition) , but
Raspbian currently does not.
