Hi,<br>
<br>
I may have found a way to make fs-update run on steroids. But I need<br>
to know if all/most SD cards are like mine.<br>
<br>
Please open your XO-1.5 and run:<br>
<br>
cat /sys/devices/pci0000:00/0000:00:0c.0/mmc_host/mmc2/mmc2:*/scr<br>
<br>
And post the output here.<br>
Please state clearly if this is a SD card that you installed yourself,<br>
or if its the one that was shipped in the laptop by default from OLPC.<br>
<br>
The optimization I'm looking at is that fs-update first erases the<br>
disk (which only takes a split second) and then spends most of its<br>
time writing zeroes, but for some SD cards (hopefully most of them),<br>
erasing the disk zeroes out the whole thing anyway. So no need to<br>
spend loads of time writing zeroes.<br>
<br>
Thanks,<br>
Daniel<br>
