How to create ext3 partition on SD card with ClockworkMod Recovery?

GParted Live is not the only way to partition SD card for A2SD+ NAND Android ROM. There is a built-in advanced function in ClockworkMod Recovery to help create ext3 partition on your SD card. And it is easier than GParted Live method but you need to get ClockworkMod Recovery installed first…

Step by Step Guide

  1. Backup your SD card data to PC before start partitioning.
  2. Power on your phone and don’t let go power button.
  3. DFT MAGLDR Bootloader will be loaded.
  4. Press call button to load 1. Boot AD SD.
  5. ClockworkMod Recovery will be loaded then.
  6. Use volume down button to go down to ‘advanced’.
  7. Then press call button.
  8. Select ‘Partition SD Card’.
  9. Select the ext size that you want (128M, 256M, 512M, 1024M, 2048M or 4096M).
  10. Select 0M as the Swap Size.
  11. Copy back your data to SD card.
  12. That’s all.

Note – only ext3 partition will be created. And 38.76MB used up for 512 MB ext3 partition.

  1. i am not using cloeckwork Mod to create partition now i am using “EASEUS Partition Master 6.5.2 Home Edition”. but i encounter once of my 8g HC sd card cannot create & delete partition at all. i already format ir several time but still cant make it.
    do you have any idea on this issue Jayce? seek yr advise here.

  2. why is it that when ever i creat partitions on my 32 gb card,the phone doesnt use it as memory.
    i followed alll the steps but i still get the same results why?

  3. Comparitively, would u prefer ext4 to ext3? I read on wiki that ext3 has stability issues. I’m considering it only coz it’s more convenient to make a partition on CWM, and my motherboard (OLD) doesn’t support USB from boot. Thanks.

  4. hi,

    thanks to your guides, i now have android on my HD2.

    I had flashed TyphooN CyanogenMod 7 v 2.3 ROM using CWM. Then I created a 4GB ext3 partition as suggested above. However, the phone does not use it as memory. Do i need to install anything else or do I need enable A2SD somewhere?

    Thanks

  5. hello,
    thanks for the desprection. I have 8gb sd card. I did it for 2 gb. Is it mean if I install an app it will place on the 2gb partition or the rest or on the phone? The 2gb partiton is necessary or 1 gb is enough? Thanks for answer

  6. after i follow all your step, i try to put sd card into notebook, it tell me to format the sd card. i cant copy directly the file. coz notebook wouldnt recognise my sd card. should i format it.

  7. is there any way to delete/change partitions within clockwork (or the phone) i.e not using a computor?

    i want to change the size of my ext2 partition.

  8. Hi Jayce,

    I’m pretty sure I did everything as detailed.
    But even then the internal memory is diminishing when I install applications.

    After I installed NAND 2.7 and Apps2SD via CM Recovery, I installed just 3 basic apps (Adobe Air, Adobe Flash & SPB time) and now I have only 71MB internal storage left.

    Please advise on this.

    Thanks in advance!

  9. hi jayce, i’m already created ext3 partition on my sd card with ext size 4096M, if now i want to change it to 2048M it is posible to do that?

  13. I am having a problem with AD Recovery in the Clockworldmod recovery. it always says that there is no boot loader. What do you think might be the problem.

    Also finding it difficult to instal The clockworldmod recovery on the computer. Any help will do

    Thanks

  14. Hi Jayce,

    Did the procedures as described above successfully with 2GB as EXT3 partition but after rebooting, internal memory is still the same and hasn’t increase.

    aMAGLDR v1.13 shows under Mounts and Storage Menu:
    – mount /system
    – mount /data
    – unmount /cache
    – mount /sdcard
    – mount /sx-ext

    is that correct or should I change any of these.

    What else must I do to get Android ICS 4.0.4 to recognise the additional ram in EXT3?

    Thanks in advance.

  15. Sorry Jayce for my ignorance.

    Does NexusHD2 Android 4.0 Ice Cream Sandwich Beta10 NAND ROM for HTC HD2 have A2SD+ support?

    Thanks.
