Update on Beta 4
It seems I'm getting mixed results with these betas. I'm not sure why this is occurring, some people have been able to get this working right while others have had a hard time with it.

Currently, I'm rebuilding the entire program. This takes a while because I have to figure out how to pack all these options into the program but make it small enough to where it will run correctly.

I will say that some of the beta features are coming back out...one of them is the search for a partition code. I suspect that code may be leading me into issues with certain platforms, so I'm going back to the 2.7.5.2 method of mounting (mmcblk0p2 or mmcblk1p2).

Also, parts of the code will use Busybox Ash (the only code that won't will be starta2sd, which will still use Bash for the time being). The startup code will definitely use Busybox Ash.

Until then, here are the links to the the last two betas and the last official release:

Version 2.7.5.3 Beta 04 - http://www.darktremor.info/files/a2sd/dtapps2sd-2.7.5.3-beta04-signed.zip
Version 2.7.5.3 Beta 03 - http://www.darktremor.info/files/a2sd/dtapps2sd-2.7.5.3-beta03-signed.zip

Beta 04 took longer than I expected to release. I have done major changes to the code:

1. New commands: convert-ext4 - This will convert your EXT3 partition into EXT4. Just a friendly reminder on this command: Not every rom supports EXT4, so it is possible to go into a boot loop if you switch roms. Use with caution.

2. Reworked convert-ext3 (convert-ext4 gets similar code)...now a flag file is set before the reboot (no conversion is done before the reboot). At load time, the conversion is performed. This takes longer in the reboot process and you may think your phone has locked up...wait about five minutes before doing anything with the phone.

3. Repair is rebuilt...now it uses existing commands to repair the setup (reinstall, remove, cachesd, cachepart, nocache, datasd, nodata). Definitely shrinks the code.

4. Added fix_permissions program to the package. This may help with Superuser issues when using the datasd feature. It is used in reinstall, remove, datasd and nodata.

5. a2sd install is back!!! Both a2sd install and a2sd reinstall do the exact same thing.

6. Dalvik heap code has been shrunk and now creates a file called dalvikheap. Actually, the code has been doing this all along (since about 2.7.5.2, I think), but I never put the code in to use the file.

7. Low Memory Killer code has also been shrunk and uses a file caled dtset_lowmem to set the low memory killer parameter.

8. Replaced Busybox PS function with Toolbox PS. The issue with Busybox PS is that it gives a false reading when I look for android.process.acore (which is the main program when the GUI starts up). If that is present, the program thinks you are trying to run Darktremor without any command line parameters. This was because Busybox would report the process was there when, in reality, it wasn't (validated this when my phone was boot looping.) Toolbox's PS reports the correct setting. This should fix the bootlooping issues some people are experiencing.

9. New commands: usedtbusybox and usedefaultbusybox - these commands may help in diagnosing issues that is may be related to the native Busybox on your rom. a2sd usedtbusybox will use the Busybox that is packaged with Darktremor. a2sd usedefaultbusybox will turn back on the scan behavior of the program introduced in Beta 03.

10. Support for Darktremor Apps2SD version 2.7 and earlier has been discontinued. To upgrade correctly from one of those versions, use version 2.7.5.3 Beta 03b or earlier.

11. Finally fixed stalled boot issues (or at least my tests with several roms says so.)

See the change log for additional details.

You will notice that if the program runs repair and finds a problem, it will correct the issue and reboot. You will see a second reboot when the dalvik-cache clears (this is to fix timing issues with CyanogenMod...I can't control that startup as well as I can other roms). This only happens if repair is ran or you flash a new rom (as repair will realign all data). If you are upgrading from a previous version of Darktremor, you should not see the reboots.

This is Darktremor Apps2SD, a multipurpose program that primarily allows a user to execute applications created for the Android OS on their Secure Digital card (with the proper setup...more on that later). But, Darktremor Apps2SD is all about stability. The goal is to be able for all users of the Android OS to be able to take advantage of a method to run their applications from a secure digital card.

But just because the Darktremor Apps2SD is all about stability, doesn't mean it isn't packed with features:

- Move applications (both free and paid) to the Secure Digital card.
- Move Dalvik Cache to run either from your Secure Digital card or from your cache partition and clears the cache on demand.
- Boot Loop Protection: prevents the phone from boot looping in the event the SD card could not be mounted.
- Dalvik JIT for faster performance on Roms which support it.
- User selectable sizes for the Dalvik heap sizes, allowing a user to freely optimize their system.
- Activate a swap partition on your SD card and sets how often the swap partition is utilized.
- Automatically fixes configuration issues.
- Users can check the free space on their SD card and check the installation to make sure all is setup correctly.
- Runs ZipAlign on demand...this makes your programs load faster.
- Built in help system for easy reference of commands.
- All features can also be reversed without repartitioning your Secure Digital card.
- New logging features assists in troubleshooting issues.
- Commands to set the Low Memory Killer feature at boot time. Great for those people who are the "set it and forget it" type.
- And more...

Darktremor Apps2SD is not the same as Froyo Apps2SD. Froyo Apps2SD creates a secure folder on the FAT32 section of your SD card (this is the section that you see when you mount your phone to your computer) and stores the programs there. This is nice as you don't have to do anything special with the phone, but it isn't backwards compatible with older versions of Android (Cupcake, Donut, Eclair) and, because of the way Froyo works, older programs not designed for Froyo will automatically stay on your internal storage (unless you install a program that forces the move to your SD card).

Darktremor Apps2SD takes a different approach. Based on the original CyanogenMod works, Darktremor Apps2SD uses symbolic linking to force Android into moving your applications to the SD card. Because Android will not allow anything to be ran from the FAT32 partition on your SD card (and, in Froyo, it will only allow you to run programs from a special folder), Darktremor utilizes filesystems called EXT2, EXT3 and EXT4. Each one of these filesystems is native to Linux (the operating system running Android), which allows you to run programs from them (same as, say, a computer running Ubuntu). This method is completely compatible with all versions of Android, including Froyo. In fact, you can run both the Darktremor Apps2SD and Froyo Apps2SD at the same time.

2. Delete 05mountsd from /etc/init.d/
3. Change barrier=1 to barrier=0 only for DT-CM7-2.7.5.3b4-EXT4-B0-signed.zip <=== I'm using this

Known issue in DT 2.7.5.3b4
- Low volume bug across all medias.
- Temp but working solution ==> WIPE CACHE after u flash DT before u reboot. Thanks to mtw4991 for the solution!

Please try the above ONLY if u have EXT4 partition.
If you are using ext2/ext3, you may wanna see my post here. ==> http://xdaforums.com/showpost.php?p=11950587&postcount=674

To boost ext4 performance, you may wanna enable data writeback (default setting = ordered). I did not put into script as its optional. Note that this is a ONE TIME command input only. Only when you repartition the ext4 then you need to input again. Reboot to see the results.

Instructions for Inputing EXT4 data writeback.
1. From terminal or adb
2. Input the command as per the code below.
3. Reboot device.
Credit ALL to tkirton. I just amend the scripts to suit my needs

if you really think darktremor is too complicated, try using Simple2Ext if you are using a cyanogenmod ROM.

You can also choose Link2SD if you are not using cm7 (as i can see ur on stock)

darktremor a2sd is not simple, even android isnt. ive used ****loads of time to read and test by myself when i was a noob, too good luck mate!

Hi,

I've 2 questions:

1. I have a HTC Desire GSM that's running CM 7.0.3 and I've run the DT A2SD script to put my apps and dalvik-cache to the EXT partition on the sdcard. I wish to update to CM 7.10, and the instructions seem straightforward enough (nandroid, flash, that's it). I'm wondering if I need to do anything about A2SD for the update?

2. I wish to upgrade to a larger sdcard. How can I migrate from my existing sdcard to a new one?

1)
nandroid
wipe cache
wipe dalvik
flash update
flash darktremor
reboot
done

2)
boot to recovery mode
nandroid backup, only choose [android_secure] and [sd-ext]
turn on usb mass storage
move everything on sd to computer
turn off usb mass storage
turn off phone in recovery
switch hardware sd card from old to new
do not power on phone normally
must directly boot into recovery mode
partition sd card - your desired ext and space etc.
usb mass storage on
everything from computer to sd
usb mass storage off
nandroid restore (the one only with the two options ticked)
reboot phone - phew finished!

Shiyou, do this, in order, using Temasek's modified DT script at the bottom:

1- move all files from sd card to pc
2- format and repartition sd card to ext2=1/1.5gb, swap=0, FAT=remainder
3- convert ext2>ext3
4- convert ext3>ext4
5- mount sdcard in recovery and move sd card contents from pc back to sdcard
6- flash rom/kernel/gapps(optional)/modified DT script
7- recovery, run fix_uid_mismatches
8- wipe cache only(fixes low volume bug, dont' wipe dalvik)
9- reboot (go do something, this will take some time)

10- in terminal run the following:
11- su (get superuser permission)
12- a2sd check (make sure a2sd is running)
13- a2sd zipalign (only need to run this command once)
14- a2sd reinstall (will reboot) then;
15- a2sd cachesd (will reboot) then;
16- fix_permissions
17- reboot into recovery, wipe cache and reboot

Hope this helps
