unCoRrUpTeD SD--PARTITIONER [Partition SDCARD without losing fat32 contents] (SCRIPT)

[unCoRrUpTeD]

This is outdated and probably does not work.

UnCoRrUpTeD SD--PARTITIONER​

I have made this really easy to partition your sdcard while preserving all data on the fat32 partition.This one is used to setup your sdcard for a2sd and swap instead of using the built in partitioning program, which will destroy all your fat32 contents. Eventually I will add support for backing up the ext partition if you want to resize the existing partitions.

You have the option of specifying the size of the partitions in /sdcard/sdpartmap.txt

To specify your own sizes and filesystem do..

c:\xxxxxx\adb shell
/ # echo 150 200 ext4 > /sdcard/sdpartmap.txt

replacing 150, 200, ext4 with your own
.
The 1st number is a2sd data partition (system/sd or sd-ext mounted at /dev/block/mmcblkXp2)
The 2nd number is swap partition. (mounted at /dev/block/mmcblkXp3)
The 3rd entry will be for ext3 or ext4 FS

It's best to do a2sd data in increments of 256MB and
swap in increments of 32MB

If you don't specify an ext type it will default to ext2.
If there is no sdpartmap.txt file the partitions will be automatically set to
a2sd data = 256
swap = 0
ext type = ext2

Make sure you have enough free space on the card to accommodate the extra partitions until I incorprate checks for that.

INSTRUCTIONS:
1. Download unCoRrUpTeD_SD--PARTITIONER.zip

2. Reboot into recovery

adb shell reboot recovery

3. Unzip the contents of sdpart.zip. There should be a folder named sdpart. Push the files inside sdpart folder to /tmp/

adb push c:\xxxxxx\sdpart /tmp/

4. run /tmp/sdpart.sh in adb shell

adb shell /tmp/sdpart.sh

If sdpart.sh doesn't run then you will have to chmod it before running it, but it should already have permission to run.

adb shell chmod 777 /tmp/sdpart.sh

If for some reason you can not push the files mount your sdcard through your phone and copy the sdpart folder to your sdcard and then

adb shell reboot recovery (might need to do adb reboot recovery or just reboot into recovery)
adb shell
mount /sdcard
cp -a /sdcard/sdpart/* /tmp
/tmp/sdpart.sh

you said you could make it into a flashable Zip /
Would love to see this.
ADB Retarted.....

That's why I put step by step instructions. I'll have to find the flashable one.

Worked wonderfully!!!

 

[old.ghost]

will try out, thanks.

Does this work for the droid incredible?

 

[unCoRrUpTeD]

It should work on any phone, but you should back up your sdcard to a PC every once in a while just in case your sdcard gets corrupted or quits working.

How can I tell if it worked? Can I check my partition sizes or my ext somehow?

I'll add some things to the OP later today. When you run the script it should output your SD partitions before and after.

You've got to be kidding me.
Saves me the trouble of transferring 16 GB everytime I partition.
Waiting for the flashable zip.

Hey you did a good job but there's some bugs in it

the script

$parted $extmount -s mkpartfs primary ext2 $newfat $newa2sd &> /dev/null ;
if [ "$exttype" = "ext4" ] ;
then 
$mke2fs -T ext4 ${extmount}p2 &> /dev/null ; 
fi

obviously ,it can't creat ext3

so I crrect it

$parted $extmount -s mkpartfs primary ext2 $newfat $newa2sd &> /dev/null ;
if [ "$exttype" = "ext2" ] ;
then
$mke2fs -T ext2 ${extmount}p2 &> /dev/null ;
elif [ "$exttype" = "ext3" ] ;
then 
$mke2fs -T ext3 ${extmount}p2 &> /dev/null ;
elif [ "$exttype" = "ext4" ] ;
then 
$mke2fs -T ext4 ${extmount}p2 &> /dev/null ;
fi

I ran into a problem with my java code and got frustrated with trying to figure out why it doesn't work correctly. That and my wife was getting upset that I was on the computer all the time. I have been running the stock ROM on my EVO 3D since getting it on launch day and just recently flashed some ROMs in Boot Manager to test some things out.

 

[drfr]

What if I wanted to go back and delete the ext partition?

 

[tristan202]

Somehow I fail to see how this is easier than using the parted that's built in to almost every recovery out there.

But maybe that's just me.

 

[unCoRrUpTeD]

Just make the fat partition the size of the sdcard and swap and ext both 0.

When using parted in recovery you lose your data (pics, downloads, backups, etc). This way you won't lose anything.
