    Hi, thanks for the tutorial. A bit question I have,
    I partitioned my sdcard to 2gb ext3 and 6gb fat32.
    First all looks good until my phone used ext about 512mb-I think, don’t know the exact number- and then, it seems to stop using decades ext3 and start consuming internal memory. I still have about 1,5gb free on ext3, but every new app now using internal memory instead of ext3 partition. Any suggestion on this?

      I’m not sure why your Android setup stops using the EXT3 partition, actually. My guess is that it’s related to the custom ROM you’re using.

    When i load Gparted as mentioned above it searches for Dev/sda and it dont find and closed automatically …what to do

  • PR

    you told that you corrupt your sd card and had to format it, can you tell me how you did this ?

    i have a galaxy 3 (apollo).
    i partitioned my sd card but cant find a2sd+
    please help me

    First and foremost, thank you for the intuitive guide. Unfortunately for me, I encounter some problem from Step 11 onwards. After GParted was loaded, I mounted my sd via my android device, but my SD storage drive did not appear in the GParted window even though I restarted it and refresh the devices screen.

    I really need some help with this. I’m using a ScanDisk 8GB microSD HC. I even tried partitioning with Acronis Disk Directory Home, but that too was unsuccessful.

      Unfortunately, I’m not sure why GParted doesn’t recognize your SD card. It happened to me too once, but that was because my SD card was corrupted. Is your memory card fully working? Does both Android and Windows (or Mac OS) recognize it?

      • yZ

        Thanks for the reply techcredo.

        Yes. Both my windows and android device recognize the card and is able to access it.

        I have tried multiple time, including mounting via recovery mode. but still unsuccessful as well. :(

        • techcredo

          I guess you can always use the app ROM Manager to partition your SD card as a workaround, but then you can’t have a larger partition than 512MB.

          • yZ

            I guess thats my only option left. I’m thinking if i can use ROM Manager to reflash ClockWork to AmorAR and then use it to partition my sd. But somehow the “Flash Althernate Recovery” option is greyed out for me.

            Anyway, thanks alot.

    @happyhuman Ironically, it sounds like you’re running low on internal storage because you’re moving apps to the external storage. Files moved to the SD card with Android’s own a2sd will still use quite a lot of internal storage, because for privacy reasons – the Android system never stores application data on an SD card.

    With a2sd+, however, the EXT2/3/4 partition on the memory card more or less becomes an extension of the internal storage, and it should also work automatically unless your custom ROM developer has specific instructions for it. So if you have a ROM with a2sd+, *don’t* move files to an external storage, because they will usually not be moved to the partition. A2sd+ basically tricks Android into thinking there’s more internal storage than what actually is available, so think of the partition as an internal rather than external storage.

    By the way, unless your HTC Desire is S-OFF and you use a special HBOOT, Oxygen is not ideal to use on the Desire when it comes to increasing space for apps. This is because Oxygen doesn’t have built-in support for data2sd, which also moves the Dalvik cache to the SD card partition. I have installed 165 apps and games on my HTC Desire and I still have 25 MB left on my internal storage.

    I recommend Redux v.1.0.2 if you want to switch, it’s a great vanilla Gingerbread ROM and data2sd can be flashed as an optional add-on. Ginger Villain ROM should also be able to move the data to the SD card, via commands in the app Terminal Emulator. It’s easy and instructions for this are listed in the first post in the ROM thread.

    Thanks for the tutorial, have a question.
    I partitioned the SD card as instructed, and then installed a new custom ROM (Oxygen 2.0) and it does not seem to take advantage of the new partition. According to Titanium Backup SD card’s a2sd partition is almost not-utilized (1.01 GB free out of 1.05 GB capacity), while Internal memory has only 5.4 MB free, i.e. I run low on space just like before (I have around 130 apps installed). I have installed Spare Parts and set the apps to be installed into External memory by default. I also installed Apps 2 SD and made sure I moved all movable apps over to the SD card. Yet the problem persists. I don’t know what to do, and I am confused to be honest.

    Could it be that the ROM is designed to support “froyo style” apps2sd, and your method of partitioning is not exactly suitable? I am not sure I understand the differences between various concepts – I know there is this froyo style, then a2sd, then a2sd+, and it’s all confusing.

    Can you comment please?
