Hi Juanisan,

In fact i tried even more linux distributions, but adb cannot detect the device.

Do You have a hint how to get it runnning ?

Maybe auto-mounting/unmounting your USB drive with autofs would help?

More info here: http://wiki.debian.org/AutoFs

I already use autofs for automounting.

Besides I find the unmount feature in autofs pretty insecure. The manual says, the HDD gets unmounted when itīs not used. So before I plug off the USB-HDD I must know if it is already in mounted or unmounted state;

Now that is a point I didn't consider: I must have something like a feedback from the plug if the unmount procedure has succeeded (sometimes it is not possible to unmount a HDD). I think flashing one of the LEDs would be the right thing...

So it should look like: press button to unmount; wait some secs; if the blue LED is blinking longer than 5 seconds the unmount procedure succeeded; the USB-HDD can be now removed from the USB port.

Regards,
Peter

Thanks for the answer, but I wonīt spend that much money for just one button, thats ridiculous. I think I will try using  the console port for transmitting a signal to the sheevaplug. Unfortunately I donīt know where to start.

Hello,

I regularly have to unmount my external 500GB USB-harddisk before I can pull it out safely. This means I must switch on my notebook, login with ssh onto the sheevaplug, unmount and shut down the notebook.
I want the Sheevaplug to have a button so I just have to push this button, the harddrive gets unmounted and I can pull it out safely. Unfortunately there is no such button Wink .

Anyone here who maybe solved it another way ? Is there a possibility to reconfigure the reset button ?

Any help is appreciated !

Regards,
  Peter

uname -a:

Linux hostname 2.6.30-rc6 #2 PREEMPT Wed May 20 05:42:04 MDT 2009 armv5tel GNU/Linux

I have to find out how to raise the block size for reiserfs, so results follow later.

By the way:  does anyone know how to set reiserfs flash-memory friendly ?

regards,

 Peter

Some news,
Actually I tried the combination of ReiserFS and CIFS. Now it is much better, though it stutters every 2-4 minutes for a half second.
I still have to change the block size, however I donīt know how to find the internal block size of the sdcard.
Cheers,

Greetings,

Sorry for asking instead of helping:
What is Your intention of using OpenUSB, or in other words: what is the difference between both methods ?

cheers,

Hi !

I am experiencing strange problems with my 32GB SDCard.
When recording from my dreambox500 to the sheevaplug using cifs to a usb-attached harddrive there are no problems.

But when I try to record to the 32gb card, the recording is very choppy, after half an hour the dreambox even stops the
recording with the message "write error on share".

- I tried using cifs- and nfs-shares, no change, still choppy:
- I put the card into a card reader and attached it via USB to the sheevaplug, still choppy;
- The card has been tested; it was filled completely with a file, then compared with the original: no problems;
- When i copy manually files to the sdcard while attached to the plug there are no problems as well;

Some more info:
- the streaming is never more then 800kb/sec, the card is capable transferring 4MB/sec;
- i used sheevaplug-installer-alpha-6 on the plug
- i even used a kernel with sdcard slowdown, no change

some observation on the plug:
- while recording on the USB-Harddrive one can see regular flickering of the Network-LED,
- when using the sdcard one can see irregular flickering. There are breaks in the transfer up to 8 seconds. Watching the  increase of bytes of the recording files looks very similar: after regular growing of the file, there are often stops of ten seconds in the increase;


first guess:  The card is too big, the plug has too much DMA overhead, or something
second guess: SD Cards write with a certain block-size, which has to be set ... or something

Unfortunately i find my guesses not really logical, since copying a simple file over network to the file works smoothly.

What do You think about it ? Every guess is welcome.

cheers,

 Peter
