SD Card EXT 3 Q. - Android Software/Hacking General [Developers Only]

When formatted with EXT3, can i simply drop anddrag stuff into /sdcard ie folders for music and stuffs??
Thanks.

When you partition your card its with a fat32 partition and and ext2/3/4 partition. your ext partition will be used by your linux android platform for a2sd+ feature and wont be accessible to you when you connect your device as a drive.
However the fat32 partition will be visible to you and you can put all your stuff on it normally as you do.
hope this helps.

please help sd card problems

ok here is my situation i am running a rooted g1 with amon ra 1.5 recovery and cyanogen 4.2.12.2, i used the partitioning function from the recovery options to format my sd card , now that i have the fat32 , ext3, and swap partition i was able to move my cache and apps to the sd and everything is working great, the problem i am now having is i cannot access the fat32 partition , the mount/unmount option is faded i can see how much space is on it but i cannot put any of my files back on the card it also doesnt give me the option to mount the sd card anymore when i plug it into my computers i have tried it on my mac, windows xp laptop and my asus eee linux laptop
any help would be great thanks
You have probably corrupted the partition table somehow.
If you don't have anything precious on the card, try to wipe it and start over.
But since i know life i'm almost sure you have files there that you wish not to lose.
Tell me, did you format all the partition after creating them?
Did you unmount/re-mount the partitions after creating/formating and BEFORE you copied any files to them?
If the answer to any of the above question is "no", you've probably screwed up.

No I partitioned the card using amon ra recovery 1.5 it has the option to do the ext2, Swap and the fat 32 partitions all at once I did 96m swap 512ext2 and then upgraded it up to ext4 and left the remaining for fat32 , when I save files it does put them in the fat32 patitition I believe since my ext4 partition does not loose any space and I already ftp'd most of my files back to the card that would easily exceed the 512m partition I just can't get the mount option to come up now when I plug it into my computer other then that everything works perfectly
open console and type "dmesg", then insert the card and type it again, compare the few last lines, if there's anything diferent saying about MMC/SD, post it here (only the card related stuff)
Good luck,

[Q] Link2SD and Partitions

I have an HTC Hero rooted with stock 2.1 firmware
I installed Link2SD and read through the development post on this forum but encountered and issue I cannot figure out how to resolve.
I reformatted my SD card with 2 primary partitions using MiniTool. I re-sized my standard partition to allow for an additional 400MB partition then formatted the unallocated memory to ext3 format.
So now I have 2 partitions that look like this in MiniTool (4GB SD card):
Partition FileSystem Size Status Type
-SDCard FAT32 3.30GB Active Primary
-AppsPartition ext3 400.06MB None Primary
(sorry cant get more spaces between words, dont use forums often)
I thought that was all I needed to do but when I put the SD Card into my Hero it just tells me I have a damaged SD Card. What do I do to fix this?
I just wanted to say I figured this out on my own. I don't know what the problem was but I reformatted the SD card from the Hero and it only formatted the SDCard partition and then I had to reformat the AppsPartition to FAT32 file system in order to be usable by link2sd and it worked.
No idea what caused the problem to begin with but got it resolved, that's all that matters right?
I had problems too until I formatted partition 1 as FAT (aka FAT16 - NOT FAT32), and the second as FAT32 or Ext2/3.
The key for me was the first partition being FAT.

How to Use EXT3 Filesystem For The SD-EXT Partition??

"Use EXT3 Filesystem For The SD-EXT Partition,To Avoid Any Errors While Backup" Thiz is the suggestion from developer. But I dont know how to do this
please help:

After you create a partition, it needs to be formatted to be usable. If you created the partition on your SD card by putting it in your computer, you have to format it separately. You use your preferred software to format, and you must specify how you want the new partition formatted.
If you create a partition on your SD card through your phone's recovery (i.e., CWM), it will automatically format it. I think CWM uses ext4 by default.

Click to collapse
Does CWM support external SD card formated with ext3 or ext4? I considered exFAT and NTFS but none seems to be supported by CWM.
CWM can read partitions which have been formatted ext2/3/4 in your computer. I'm not aware about exFAT, and I highly doubt any recovery would recognize NTFS.

[Q] Internal Storage and SD Card Formatting

Hi all.... I haven't found specific answers to my questions so am posing them here.
I am running CM11
Can you expand your internal storage without doing an entire ext sd card to internal swap? I want to use only part of my ext SD card to enhance the internal storage.
Is there any point in formatting multiple partitions on the ext SD card as fat32 / ext4 / Linux swap anymore? I thought doing this would have part of the partition used for internal storage and part as the ext sd card storage. Formatting the SD card through CWM deletes all partitions and formats it all as FAT32 for external storage only.
Thanks and go Blaze haha

You can partition your SD card on your pc into pieces that android won't recognize..follow this as a guide..the program is fantastic

Thanks ink. I will look at this more tonight but I did use Partition Wizard Home and formatted the first partition as FAT32 which is recognized as the external SD card1 in CM11 but the 2nd EXT4 partition isn't recognized by the ROM it seems. Maybe I just don't know how it would be used but checking the storage in settings didn't have any change to internal.

My SD card went dead- has Ext4 and FAT32 partitions on it

Hi,
My SD card suddenly went unmountable. My phone restarted automatically and hasn't been able to mount the card. It is not recognizable in Windows too. I just see a grayed out drive that has 0MB.
I'm using Apps2SD on my phone and I had to partition my SD card with one Ext4 partition and on FAT32.
The thing is that because the first partition is Ext4, Windows cannot see the second FAT32 partition.
How can I check if my SD card really went dead or is it a matter of corrupted file system?
What program can I use to scan and check Linux partitions on SD card?
