I was trying to create ext2
/ext3
/ext4
partitions on the SD card. I tried ClockworkMod recovery and it didn't work. Nothing seems to have happened.
I also tried using MiniTool and that also failed. I tried both Disk Utility and GParted in Ubuntu and it still didn't work. For MiniTool, Disk Utility, and GParted, after I finished partitioning the partitions showed up on the computer OK, but when USB's disconnected the One X says that the SD card's corrupted.
Has anybody done this? Or is there some other way to solve this?
Or maybe it's not possible because the SD card is built-in?
Thanks!
After some more playing around, it seems that the problem might be something related to a partition table.
When there's no partition table, it works fine, but after I add a partition table it seems that the phone can't recognize the SD card anymore.
