Sorry, I'm not actually sure how those 3 files got to be there. The "writing" didn't work.

Here is what is happening:

I put in the SD card.
I open Win32.
I try writing the file.
It doesnt work because it says Not Responding.
I restart the laptop.
After I restart, I see the SD card with the 3 files in it

Windows can only see the FAT partition (of 128MB) and not the linux ext4 partition. (It's sniffy about that sort of thing, and refuses to recognise non-MS formats ;) )
The image has (probably) been written to your SD card OK.
However, the Ubuntu file system img will likely only fill about 8GB of your 32GB, leaving the rest uninitialised/free.
I use 8GB or 16GB cards - they're cheaper!

I suspect that what is happening is that, while it says "Not responding", W32 Disk Imager is writing out the image to your card and you are rebooting your PC after the BOOT volume gets written out but before the root filesystem is. I could be wrong, but try once more and go and leave your PC for an hour or two after starting writing out the image. Then come back and see if it has completed. You need to be patient :)

Sorry, I waited for like 2 hours, and the progress bar still said 0%. After I rebooted my laptop the same 3 files were there.

Do you know if Win32 works on Windows 8 (that's what I have)?

Also, are there any alternates to Win32? The only one I found was http://www.roadkil.net/program.php?ProgramID=12 and that didnt work either

I'm not a Windows user and so not the best person to advise on imaging software compatibility and alternatives. I'm guessing you don't have a Linux machine you could attempt this from?

No, I don't. It's Ok, thanks for the help.

Do you know of any alternates to Win32?

And do you think that this might be a problem with the laptop's SD card reader? Should I go out and buy a SD card reader like this:

Also, what should be the contents of the Micro SD card when it is ready to be used?

What should be there in addition to those 3 files?

As mentioned above, on Windows you will not be able to see anything other than the files in the FAT partition. You'll need to wait until the SD card is loaded onto the Parallella or another Linux machine before you will see the ext4 formatted linux filestore.

I've tried to replicate your problem on my (hardly used) Win 8 tablet.
After I downloaded and installed Win32 Disk Imager onto Win 8, I tried to get Win32 to write the image file to the microSD card.
I got similar results to you - i.e. hangup, no responding for a long time, etc.
But then I noticed that the default is that Win32 writes to the C:\ drive :shock:. It seems to hang with the error message "waiting for task".
A nasty moment - but no harm done.
I switched Win32 to point to the MicroSD Card drive on D:\ (I think yours is E:\ ..?). Seems to be happilly writing away as I type, showing an active progress bar. :)

Sorry, but I wont be using the actual build to check it worked because my Parallellas are already built. But I hope that helps.

Cheers,
