Hi ! I have a c700 for which I have just bought a 2gig Kingston SD card...
The card did not work (getting IO errors) so I brought it back to the store, thinking it was defective.. Now I have another one, and I have the same problem.. Buffer I/O error on device mmcblk0, logical block 0.. Is it a limitation of the hardware ? Of the SD drivers? Or did I just hit a model of SD cards that was not compatible with my device? Thanks |

Thanks  You're not the first person I've seen mention that although I've yet to work out what the problem is. The changes in OZ 3.5.4.1-rc might help as it has a much more recent kernel with several MMC/SD changes. Richard |

Richard Installed 3.5.4-rc2 and it now detects my card as 1.9gig free  Time to format it as ext2 and install some goodies on it..thank you very much! |

This beauty would have made a nice addition for many Zaurus users: http://www.oesf.org/forums/index.php?showtopic=19185&hl= (If it worked the way it is suposed to) Sorry for hijacking the thread. |

I seem to have problems with my SD.. Let's say I am downloading something to it using wget.. Wget just hung on me.. And if I just try to do ls in /media/card - that hangs too...maybe I should use ext2 instead of ext3 right? For speed...I just thought ext3 was a pretty good idea for removable storage.. |

I ran a fsck on the card, fixed a lot of errors (probably from once when the zaurus hung for a reason I don't know) and now, it feels much faster , and I can use the card properly again... |

I think the spec got opened. The problem is then obtaining the specs for whatever card it is you're trying to work with. |
