Hi everybody,

It seems things come more clear!

Concerning Solarnz question, by far I think option2 is better. More if you say that requires less modification. By the way, if you need further testing, count on me!. It will be great having a Tiamat supporting this rare partition.

About the question from Aeren, I do not see any important differences betwen the two partitions. I've noticed that depending on the ROM I've flashed or if the sd-external was present or not at boot time, the system uses mmcblk1 or mmcblk0, but allways in both cases the breakdown of the 32Gb memory into 11 partitions is identical with the same sizes.

By the way, this is what mount command says in may tablet:

# mount

rootfs / rootfs rw,relatime 0 0

tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0

devpts /dev/pts devpts rw,relatime,mode=600 0 0

proc /proc proc rw,relatime 0 0

sysfs /sys sysfs rw,relatime 0 0

debugfs /sys/kernel/debug debugfs rw,relatime 0 0

none /acct cgroup rw,relatime,cpuacct 0 0

tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0

tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0

none /dev/cpuctl cgroup rw,relatime,cpu 0 0

/dev/block/platform/sdhci-tegra.3/by-name/system /system ext4 ro,relatime,barrier=1,data=ordered 0 0

/dev/block/platform/sdhci-tegra.3/by-name/userdata /data ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0

/dev/block/platform/sdhci-tegra.3/by-name/cache /cache ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered 0 0

/dev/block/platform/sdhci-tegra.3/by-name/pdsb /pds ext2 rw,relatime 0 0

/dev/fuse /mnt/sdcard fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0

/dev/block/vold/179:1 /mnt/sdcard-ext vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

/dev/block/vold/179:1 /mnt/secure/asec vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

tmpfs /mnt/sdcard-ext/.android_secure tmpfs ro,relatime,size=0k,mode=000 0 0

/dev/block/mmcblk1p10 /mnt/internal2 ext4 rw,relatime,barrier=1,data=ordered 0 0

So, partitions are not refered for mounting by its /mnt , but for its /dev/block/platform/sdhci-tegra.3/by-name.

This is also what I see in /dev/block/platform/sdhci-tegra.3/by-name:

# ls -la

Were SDC is the famous 26 Gb lost memory!!

The final question I have is why this special partition table in Hong Kong-Taiwan.

It seems me as if motorola released a beta version of 3.1 in this relatively small market. I remember my tablet before reflashing had some more functions, specialy native external usb support. If this is correct, that makes sense to the fact that Moto does not want to publish this HK ROM (by the way, it was GAS-ASIA-HUBBLEHKTWN GEN-P007 Kernel 2.6.36.3 Build H.6.1-17-CN-40). Meybe in future they will come up with an international version that handles that (or they may drop it).

Good job!
