First, the most interesting result:
My C3000 is faster than ever. Every application starts up quicker and there are no more spin-up times when the microdrive has felt asleep.
Compare yourself:
Reboot until the sound can be heard: microdrive 142s, SanDisk Ultra II 120s (-15%).
Starting Opera after having rebooted until the error message appears (startpage cannot be found): microdrive 16s, flash 10s (-37%)
It's really impressive! But the most impressive thing is, that there's no time lag after the microdrive would have fallen asleep.
For anyone who's interested:
I've just exchanged the 4 GB microdrive with a SanDisk Ultra II card. It's easy:
1. Have a look at the internal-pictures from the 3000:
Click here!2. Remove the Hitachi microdrive
3. Insert the microdrive into your PC and have a look at the partitions, assuming the cf card is /dev/sda:
fdisk /dev/sda
4. Copy the partitions to your PC-HDD:
dd if=/dev/sda1 of=hda1
For sda2 and sda3 do the same. It's a good backup, anywhere.
5. Insert your flash card into your PC and create new partitions on it. I think it's a good idea to let the system partition (hda1) exactly as it is: about 100 MB. Partition 2 (ext3) can be changed in size. Partition 3 is the left-space-device (vfat).
6. Copy microdrive-partition 1 to the flash card:
dd if=hda1 of=/dev/sda1
7. Copy the remaining partitions to the flash card. That could be done as above with the dd-command, but the new partitions must be equal in size. Or you can mount the old-partitions, e. g.
mount -o loop,ro hda2 /mnt/OLD/
and copy the files to the newly formated partition sda2:
mkfs.ext3 /dev/sda2
And now copy the files. The same has to be done for hda3.
8. Insert the flash card into the Zaurus.
9. Reboot!
10. Wonder why the Zaurus is that fast.
