[Q] Where do I find a 2nd SDcard partition?

---

Hi,

I formatted my external SDCard with 2 partitions, so I could use it with Link2SD. Since I am on a Mac I only could format the first one, which is FAT32. Now I need to format the 2nd with ext4 but I can only do this from inside the phone. Which is no problem, except I do not understand where I can find the device, I need to format. So, to sum it up: I have already a 'linux' type partition on the SDCard, unformatted, however. And I have a FAT32 partition on it, which gets mounted by Android already. What do I need to issue to the mke2fs command as input?

This is what I get, when issuing 'mount'.

In the recovery under mounts or advanced

Thank you, I tried that first. But that does not help, since I have cwm5 installed, and that only formats up to 4GB. I need to know where I can find it in the /dev directory, so I can issue the path to mke2fs from 'adb shell'.

you sure??? i've formated my 8GB one with CWM5 before.....try TWRP or CWM6

Could be, that it offers 8 GB as well. I don't remember. But this is a 32GB card I have in use. What I'd need is two primary partitions, one around 6-8GB/ext4, the other one takes the rest as FAT32.

Can I install a different recovery mod, without resetting/erasing the phone? Is it as simple?

Ok, I updated CWM to v6 and re-checked. The max size is still 4096. Also I noted this:
After I left "advanced/partition" and turned on the log this shows up each time I select "show log"

When opening the log I get I: Can't format unknown volume: /external_sd
I:Can't partition unsafe device: /dev/block/mmcblkp1

and the "advanced/partitions" menu item is gone. "parted" in normal boot said, that I have overlapping partitions on the sdcard, which I doubt, since I did the partitioning with a special partitioning utility. Anyways, going to boot up a Linux VM now, should have done so much earlier It's just always so messed up with getting external volumes on USB to recognized.

I'll sort this ASAP thank you for bringing it to my attention

Thanks for trying so hard. Greatly appreciated

On a side-note... I tried with a VM, but whatever way I tried to connect the SD card to the Linux guest, I did not succeed. So I am here again, no way to create an ext4 filesystem from inside the phone. Currently I play with the thought about installing a minimal, chrooted debia in my phone. But then I still have the problem with parted moaning about "overlapping partitions", which must be invisible to me, since I just checked the partition table with OS X' fdisk and all numbers seem in sequence. Okay, going to the other thread
