[Q] what is app2sd and please can you help me activate it ? ?

what exactly is app2sd??
I am using RAFDROID ROM on a TMOUS HD2
in the instructions he said that if I am using a euro HD2 with 512 rom I should partition my sd card
so I did not do that and flashed the rom on my NAND
then when I started using apps I noticed that after two weeks usage I have only 50 MB left!!!!
so I want to activate app2sd and move my apps to the sd card..
so please I need some help from the experienced users on this great forum that can advise me about what exactly is this and how to activate and use it
thanks in advance!!

Apps2sd moves your apps to the sdcard, usually to an ext 3/4 partition. I don't know about the ROM you're using, but on the one I use (mdj's Cyanogen 2.6), you can move apps to external storage like this: settings --> applications --> manage applications. Then select an app and there is an option to move to sdcard.

@freeincolorado, the method you described is not A2SD+, that method is called move2sd.
A2SD+ puts the dalvik cache as well as the applications in a EXT2/3/4 partition, usually called the sd-ext partition. This method will still show you that the application is in the ROM. However, the sd-ext is used instead, depending on the chief implementing A2SD+ in their ROM, the remaining ROM space is suppose to report the partition "sd-ext" free space, however, certain ROMs are not properly done in my view, and will report the userdata partition free space instead. Such as MDJ's Cyanomodgen 7+ Gingerbread.
How to use A2SD+
Usually, they require you to partition your SD Card into 2 primary partition. The first partition is FAT32 where you store all your extras, such as music, ebook, etc (Like how your SD card is presently used). The 2nd partition is EXT2/3/4 depending on your preference, most people do not use EXT2 anymore as it does not support Journaling, since data can be easily corrupted with a battery pull. EXT3 and EXT4 contains journaling feature, so when battery is pulled, data corruption is minimal.
NOT ALL ROMS SUPPORT EXT4. This is a kernel thing, so if the rom uses a kernel that does not use EXT4, then it will not read the partition.
A2SD+ has a nice feature as well, when you switch ROM, you do not need to re-install all the applications, since all applications are placed in the sd-ext folder, including the dalvik cache. However, this also includes the system default applications which might not be compatible with another rom build.

Safe to flash an adsd+ Android Rom on my existing one?

I have Hyperdroid with CNM 7 and a2sd+ partitioned SD card.
My question to you guys is..
Is it safe to flash another Android Rom with a2sd+ on my existing one?
Or do i need to flash my Card with Panasonic SD Format and make a new partition?
Whats the best a2sd+ ROM in your opinion?
Sorry if might this had posted before..it's just a quick question

Hi,
The ext2/3/4/ partition does not get changed when you flash a new ROM.
You should be fine to flash a new ROM over your old one.
Don't forget to backup your data and when you go into MAGLDR wipe data,cache partition,and dalvik(in advanced).
Each ROM comes with its own CWM partition to flash in recovery.Do this, then flash your new ROM...
As for which ROM to choose,Imilka does a nice line in A2SD ROMS.
(Please remember,that this is only MY opinion)

That was very helpful man! Cheers!

If you're coming from a different ROM then you should do a back up using titanium backup before installing new ROM. It's highly possible it will have conflicts. Install app2sd when you close to run out space in your internal memory. Say, when you install a NAND ROM everything goes into your internal memory and whatever left should be use mostly before installing app2sd. Installing app2sd will take 195Mb from SD card and stop using your remaining space in internal memory.

[Q] Resize rocovery partition

If I resize my recovery partition on my HD2, is all data on my SD card lost? and would i have to reflash a new NAND ROM?

Repartitioning your internal memory will not affect the data on your sd card in any way.
Yes, you would have to flash a new ROM, or restore a backup.

so i take it the recovery partition clockwork uses it not on that sd card
which leads to my other question, if my rom requires a 169mb recovery and i use a 400mb recovery, will it work?

yes it will work, but you will waste 231mb of rom space. This is because you will set a system partition of 400mb, and load into it 169mb of files, BUT once the rom is running, all your user data, installed apps, etc get put into different partitions. Nothing will use the extra 231mb in the system partition, so it will be completely wasted and unuseable.

is there any sense rom that will work on a 150mb recovery? if so please share the link

Very unlikely. Why not just change the size?

bored on my help desk job, was gonna mess with my rom,but if im goin to resize i rather do it at home....lol
think im gonna try the bliss rom, any takes on it?

well you could always flash the rom, play with it, then when you get home, do a cwm backup, change the part size, reflash the rom, then in cwm do an advanced restore and just restore the sd-ext and data partitions. hey presto, system size changed and any settings you configure today will be restored into the new flash.
CAnt comment on the rom, i only use typhoon.

CAUTION; the CWM partition make it is for the SD and it WILL ERASE ALL DATA ON SD , for partition internal memory u have to use other tools on a PC (my favorite its HD2 toolkit)

Typhoon has a nice stable sense rom.?
Send me a link

Typhoon is a cm7 rom. Cm7 roms don't have sense.
I CAN highly recommend it, though. I've been on an older version typhoon for over a month now, and the only bug is the occasional failed video capture. Annoying, but doesn't happen often.

[Q] Move apps from sd-ext to NAND, then repartition SD card

Hi guys,
I've installed a CM7 ROM then installed S2E, then flashed an AOSP build to replace it. When I try to use S2E to move the apps back to NAND from sd-ext, it shows up in NAND in the first couple of boots, but later on goes back to sd-ext without S2E doing the job. I kinda figured that it's built into the ROM to move the apps to sd-ext.
What would be the safest way to move the apps from sd-ext back to /data/app, and then repartition my SD card into a single partition and use its whole storage capacity?
Thanks in advance!

try link2sd in the market,it's free,but once you've moved all u want to,boot into recovery and wipe cache partition and wipe dalvik,that MIGHT do the trick

one question, how do you want to partition your sd? i mean one fat or one ext partition? But seriously, one partition is a bad idea, i wouldnt recommend that.

@Ty5982, Thanks for the input! Will try that later.
@greg17477, I'm using Windows so I want to format it to a single Fat32 partition. What's your recommendation?

Partition ur sd card in recovery with 1gb and swap size 64mb,THEN,open link2sd and when u 1st open it,it checks your phone and sd card then prompts u were u want to send apps to,ext 2,3,4 or FAT 32,select FAT 32 as its what u want,then a error msg will appear,reboot,then open link2sd and now you've got your fat 32 lol

Won't that have moved his apps to a fat32 partition?
If I'm reading this correctly what the OP wants is to move his apps to NAND so he can format his sd card to its full capacity in FAT32, presumably so he can use it as a normal SD card (eg for a camera, moving files etc)
I personally use a very popular app called DarkTremors Apps2SD GUI, it comes preinstalled on a lot of custom ROMS. This app checks where your apps are when you launch it, and gives you the option to either move them to SD-EXT or back again. Launch APPS2SDGUI, let it check your system, then click 'Apps are on SD!' to move them back to NAND.
P.S. I don't think you can wipe the SD-EXT partition off the SD card using Windows' built-in formatter. There are lots of freeware apps that can and will do this though, google is your friend =]

@Ty5982, unfortunately it didn't work. It went badly and I lost the apps in sd-ext so I ended up restoring them..
@jwchips, thanks! Will try that one instead. Yep, I've read about the tools/apps that can be used to partition/format storage devices with EXT. Thanks again.

well i would recommend tu have 2 partitions, ext and fat. Just to be safe or prapared in case your want to try a different rom. Nowadayes almost every rom uses ext partition. And you won't run out of space, if you install some more apps.

I see. Thanks! Currently I have a 512MB EXT partition on my SD card. I thought I'd be able to choose which apps to move there but it seems my ROM automatically symlinks the apps installed to the EXT partition.
So I decided I want to just install the apps to NAND since I don't really install a lot of apps and I'm using a TMOUS HD2, just for an extra boost in performance compared to when apps are installed to SD-EXT. Then I'll just selectively move apps to SD.

ah ok, on TMOUS HD2 you might do not need an ext partition

That's what I've figured..
I might just back-up everything then re-flash and repartition my phone and SD card. Anyway, thanks everyone!

Hi, I hope you guys are still around, I´ve been looking for an answer and can´t find anything, heres the question I posted on another thread:
I´ve been having trouble with my phone freezing even after full wipes, so I´ve come to the conclusion my sdcard is corrupt.
So I want to go through the Gparted process to format and re-partition my sdcard.
Currently I have 16GB class 6, which has the recommended FAT32 and 1GB ext4.
Is it safe (or even possible) to format the sd card now. I tried with Gparted and only the FAT32 partition showed up???
The rom is runnymede aio which requires the ext4
Thanks

be sure to format both partitions as primary.

[Q] Size of ext4-partition, space for apps

Hallo together,
this is my first thread in this forum.
I plan to install the NexusHD2-JellyBean-4.1.2-CM10 V1.3a [NativeSD] on my Leo and I have one principal question:
I must have two partitons on the sd-card, one ext4 and one fat32. Which of those two partitions is the one all android apps are stored/installed on? Is it possible that all apps are installed on fat32-partition? In this case a size of the ext4-partition of 2 GB would be sufficient. But if all apps are installed in the ext4-partition it has to bigger, hasn't it?
Is there an app that manages all apps to be installed on sd-card (fat32-partition)? Is app2sd the right application?
I hope someone can give me some useful advice.
Greetings,
kteamchief

Which of those two partitions is the one all android apps are stored/installed on? ext4, if you installed rom with dataonext
Is there an app that manages all apps to be installed on sd-card (fat32-partition)? link2sd
Is app2sd the right application? yes, but you need to flash a2sd script first
you should choose one of three line above
I prefer to dataonext :laugh:

if the rom is nativesd, (it is) and you install it as nativesd, then there would be no point putting teh apps on teh fat32 partition, since they would already be on the faster ext partition anyway.
if you installed it as nand, then use a script to put teh apps/data on the ext partition, , teh fat32 partition is always going to be slowest.
