"Hi guys,

thank's to your great help I was able to install Ubuntu 11.04 to the internal partiton of my AC100-10N (32GB, no 3G). I used Ubuntu for few days, but one day it suddenly freeze and after hard-reboot it didn't start again. Because of slowness and instability of Ubuntu I decided to go back to original Android instead of trying to fix Ubuntu.
I restored all the partitions which I backed-up before the Ubuntu instalation, but I wasn't able to restore the backup of the biggest user-data partition (32GB in my case), which was formatted to nilfs and on which there is Ubuntu OS installed. Probably it was backed-up wrong. All other partitions was restored correctly. Now I can boot the Android OS, but I can't get the access to user-data partition. It is probably still formatted to nilfs. The problem is, that when I try to mount this partition on my laptop, it is unsuccessfull.
Few days after I have thus partitialy restored the Android, my laptop computers disk failed and I have lost all the backups.

Does anyone knows, what should I do? How can I mount nilfs formatted user-data partition? To which filesystem should I format it?

Thank's a lot in advance!"
