I actually do most of the zeroing out on a PC with the SD card attached via USB adapter. I basically use the 512 block size as that is what fdisk calculates sizes with in Debian squeeze I'm running with on the PC -- so its mostly just convenience. Since the read occurs pretty quickly, it didn't occur to me to try other block sizes.ejsolutions wrote:I'm interested in why you only use the default 512 block size. When doing a a partition resize/move, gparted seems to optimise at 4M blocks, for the cards that I'm using.

Re: New Raspbian Image
I hope this is getting to the right thread.
If your image includes the SCSI Generic module I would very much like to use it.
My Olympus C-4040Z "webcam" requires this support and I don't know how to install the sg module.
How do I download your image?
Thank you,
Peter

Re: New Raspbian Image
Do you mean firmware for the device? Debian firmware is mostly documented here: http://wiki.debian.org/Firmware/
If you knew which firmware it required, I may be able to make a custom image for you.

Re: New Raspbian Image
You would need to install the scsi modules, like this:
http://packages.debian.org/search?suite ... words=scsi
but for Raspbian of course.
I haven't had to use scsi myself, so haven't tested this, and don't know whether or not it would work with the Raspberry Pi kernel. Do you know what sg module your device needs?

I am using gphoto2 with an Olympus C-4040Z that requires SCSI Generic. On my openSUSE 11.1 system, where the camera works, lsmod shows this:
scsi_mod 149804 4 usb_storage,sg,sd_mod,libata
Does this answer the question?
My Linux skills are about 3 on a scale of 10 (1=least skilled) so I am always playing at the edge.
I thought I would try building a kernel on my openSUSE sustem so followed the instructions here:
http://elinux.org/Rpi_kernel_compilation#Common
The command: git clone --depth 1 git://github.com/raspberrypi/firmware.git
worked, but drivers does not include sg.
Thanks for helping.
