Sharp Zaurus SL-C3000 Instruction Manual page 40

my Zaurus SL-C3000 and SL-C3100
Alternatively, if you don't need your Zaurus to act like a USB drive, or your PC runs Linux, then you
could just reformat the entire /hdd3 to linux filesystem.
You might also consider creating a small swap partition while you are at it. A swap partition is faster
than a swapfile. A swap partition between 64MB and 256MB should be fine depending on your usage
and applications.
Also note that the default installer tool (qinstaller) won't let you install applications to either /hdd3
or /hdd4. ipkg will allow you to install to those locations but won't relink the applications for you, so
you will have to use ipkg-link afterwards which is not included with the default Sharp ROM. My xipk
script which is part of my ipktools package enables you to install to /hdd3 and/or /hdd4, and also
relinks the files and directories for you. In addition, it uses the same mechanism as qinstaller and
thus applications installed with xipk can be uninstalled using the qinstaller.
If you want to maximise the space on hdd3 and you don't care about the Japane se/English
dictionary and translator, then you could remove the dictionary files under /hdd3/dict1 and
/hdd3/dict2. If you later decide that you do want them, simply copy them back from the CD-ROM
(so don't loose your CD-ROMs). On the C3100, there is additionally the MobileMap application which
has some files under /hdd3/Documents/sd_map. You can uninstall the application and remove the
sd_map directory to get more space. You can re-install MobileMap from the first CD, and find the
contents of sd_map under X:/Applications/MobileMapData/sd_map. The MobileMapData part is in
katakana. There is also the Contents_Files directory containing many Japanese books and reading
material on the C3100. If you don't know Japanese, you probably want to hide the Contents tab.
This can be done though the Appearance tool under the Settings tab. You probably also want to
remove the /hdd3/Documents/Contents_Files directory afterwards as well. If you ever want it back,
you can simply copy it from the third CD.
Lastly, /hdd3 gets wiped when you do a factory reset, but you can disable that behaviour. To do
that you need to first remount / as rw and then modify /root/etc/rc.d/rc.rofilesys and comment out
the following section:
if [ "$HDDCLEAR" = "YES" ]; then
fi
mkfs.vfat -F 32 /dev/${IDE1}3 2> /dev/null > /dev/null
Of course, after you do a factory reset, you will need to fix rc.rofilesys again so the next time you
do a reset it won't wipe your hdd3. Alternatively, you could also update .home_default.tar and
replace the rc.rofilesys in there with the hacked version and not worry about it anymore.
On the C3100, /hdd1 and /hdd2 doesn't contain anything important and are a waste of space
because those partitions are not really used except for factory reset to wipe /hdd3 which sux
anyway. Thus you can hack
so that /hdd1 is a swap partition, /hdd2 is a linux filesystem (instead of /hdd4) and /hdd3 becomes
a smaller fat partition.
Here is the default partition table:
Disk /dev/hda: 4095 MB, 4095737856 bytes
16 heads, 63 sectors/track, 7936 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Device Start End Blocks ID System
/dev/hda1 1 20 10048+ 83 Linux
/dev/hda2 21 40 10080 83 Linux
/dev/hda3 41 7936 3979584 c Win95 FAT32 (LBA)
Here is my custom partition table which has /hdd1 as a 256MB swap partition, a 1.2GB ext3
partition on /hdd2 and a 2.5GB on /hdd3:
40 of 212
dd if=/dev/zero of=/dev/${IDE1}3 > /dev/null 2> /dev/nulls
rc.rofilesys to not even mount them or you could resize the partitions
