Re: Arg! My backup doesn't work!!!
Hi, Eero, - Original Message - [snip] 1. Which ITOS release did you have? 2. Was the card so full that backup didn't fit to it or was it write-protected? 3. If you check the card for filesystem errors, are there errors? 4. What is your card type, model and size? 5. "ls -l" of the backup directory? 6. What data you had selected to be backed up (all?)? *3.2007.10-7*No. It was an empty 4GB card. It was freshly formatted and was not write-protected (the backup was made -- all Zip archives, etc. -- just a corrupt -- blank -- backup.metadata file). *Too late. Sorry, Ive since removed the corrupt backup file (I sent this question a long time ago now).*Transcend 4GB SD. *Again, too late. :(*I selected all data. As I said, it was all backed-up. Just the backup.,metadata was blank (no content). I wish I could help more, but I have since reflashed reset all of my settings manually, etc. Tim --- Weblog ~ http://tim.samoff.com Baby Blog ~ http://kc.samoff.com Photography ~ http://www.flickr.com/photos/timsamoff Music ~ http://www.adkoc.com ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

I'm sorry about this. However, I'd like to determine how it's possible that there was a failed backup without an error message. Hopefully you still have the same card, could you check a few things: 1. Which ITOS release did you have? 2. Was the card so full that backup didn't fit to it or was it write-protected? 3. If you check the card for filesystem errors, are there errors? 4. What is your card type, model and size? 5. "ls -l" of the backup directory? 6.

Looks OK. So, all you need to do is start a2dpd then, in a second seperate xterm session start mplayer and audio should stream to your headset.

As bsd version of rm has -P flag and vms delete/erase.He pro- bably knows that regular rm just removes inode from the list. It should be a little app that writes zeros or random to the "deleted" place, where removed file lives.

The shred program only sees the logical sectors of the flash. Every time you try to "overwrite" the file it will just mark the old blocks as unused and write to new fresh ones. The original flash sectors will NOT be overwritten. ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

The easiest way is to use the shred command. It will write out the file a specified number of times with random data, and optionally at the end remove the file.

All flash based file systems employ some kind of wear leveling scheme. This means you have no control of the physical address of your writes. If you just delete a file without overwriting the same flash pages afterwards one can always desolder the flash chip and read it in a programmer to dump the whole space and reconstruct the file. There are companies who make a living from recovering digital photos for people this way. The easiest way to wipe your data is to do a 'cat /dev/zero > file' after you've rm the sensitive files and wait until the filesystem is full. If it's and ext2 filesystem make sure you do this as root since some blocks are reserved only for the superuser. By filling the whole space with zero's you make sure that every free block is wiped out. For flash memories you don't have the same problem as for hard-drives where the information can still be recovered after up to 5 times of overwriting. In a flash memory the difference between a 1 and a 0 consists in roughly 200 electrons for today's densities. Add to this the fact that lots of flash memories have now multi level cells (MLC) which means more bits are stored on the same cell using 4 or more different voltages. So it is virtually impossible to scan the charge from the floating gates as analog values to build the 'previous' pattern. The noise level from scanning (using a proximity scanning capacitance microscope after delayering the flash chip) will be above the natural variation in charge. If your level of paranoia is above average ;-) contact me by email and I'll send you a little program (for Nokia N800) which fills the flash space with pseudo-random data at high speeds. It will still take some 15 minutes to fill a 2G partition with pseudo random data. dd if=/dev/urandom of=file is much to slow for this purpose. -- Regards, Emil -- Marx on sex: From each according to his virility, to each according to her need. ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users
a2dp not working, any help appreciated
Hello all, I just bought an A2DP headset (Jabra bt320s) and was trying to get it to play some music as per the instructions here (SBC DSPsink might be interesting...): http://www.guardiani.us/index.php/N800_custom_packages#Bluetooth_ALSA I followed all of the instructions, but no music and the headphones flash (indicating that they are not connected according to the instruction manual). I'm afraid Bluetooth is a bit of a black art to me so any help would be appreciated. The output of mplayer is: Nokia-N800-26:~# mplayer -ac ffmp3 -ao alsa:device=a2dpd2 /media/mmc2/Laura\ Gre ene-Moonlight,\ Music\ And\ You.mp3 MPlayer 1.0rc1-maemo.17.n800 (C) 2000-2006 MPlayer Team CPU: ARM [MENU] Can't open menu config file: /root/.mplayer/menu.conf Menu inited: /etc/mplayer/menu.conf Playing /media/mmc2/Laura Greene-Moonlight, Music And You.mp3.
