Root [FAQ]ROOT MEMORY: a2sd+ / partitions (updated 10th August 2011)

I thought it was a given. I assume a level of understanding in my faq's ;)

I'm Birthday drunk so forgive me.

No offence taken mate, I wouldn't have gotten this far without your help in particular.

Unfortunately my level of understanding on this subject is sadly lacking.

I will try harder I promise ;) :D
 
Fairy dust is essential in these matters. Its a pre-requisite. before you do anything, check your RUU is available and that your fairy dust is the right shade of pink
 
I bought a new sd card! how do I move the a2sd+ data from the old one sd to the new one?

edit:found a thread
 
A quick question:
i flashed defrost ROM and all is well except two things:
a) my internal memory is 148MB (i wiped the data before installing ROM)... so i'm wondering where's the 700MB i'm supposed to get???
b) I cant get my SD card apps (about 1GB) back on the phone.!

(pls do reply even if it comes as super-n00b)
 
download quick system info. it should give you an additional storage location called a2sd. it should show how much extra space you have

a) Internal memory is alway reported as it is. To see the additional A2SD memory space use quick system info as mentioned many times before here.
b) I think there was specific instruction to put all yours SD apps back to the phone before 'applying' A2SD

I'm not an expert so maybe you will got better answer and help from someone who is.

I think there's some confusion here. A ROM can't give you more internal memory, and while editing the partitions (advanced operation!) can, 700MB is more than is physically possible.
b) I cant get my SD card apps (about 1GB) back on the phone.!

I guess you had a (large) A2SD+ partition with your previous ROM, so as long as you took a backup (e.g. Titanium) before wiping you should be able to just restore. Can you give a little more detail?
 
Thought I'd put this question here so as not to create yet another A2SD+ thread and its aneasy one. Just moved to LeeDroid 2.3b with A2SD+. A lot of my apps used to be on the SD card using the FroYo method and I've left them that way for the moment (Ti Backup was set to restore to original location). Is there a reason why I should move them back to the phone? Got lots of memory either way so its not an issue just looking for whatever is best.
 
A2SD+ moves the dalvik cache as well, so the app will use less of your internal memory if moved. Right now you are not short of internal space, and if the apps are already on SD using the Froyo method then they don't have widgets that you use.

So the one remaining advantage of moving them is that you can access the app while the phone is connected to a computer in USB storage mode (i.e. while the SD card is accessible to the compter). With the Froyo method when the card is mounted on the PC the apps become inaccessible to the phone.
 
Thanks. So doing no real harm at the moment but probably worth moving to the 'phone' when I get a minute - if nothing else for consistancy and its just 'better'
 
Just thought I'd drop in and mention that you can partition the SD card really easily using AmonRA recovery.
That's what I did.
 
I'd just like to say thanks to danfrance for the info in this thread. It has just helped me migrate from a non a2sd+ 4GiB card to a a2sd+ 8GiB class 6 card.

Half an hour one cup of tea later alls well ;)

:cool:
 
Hey all so this took me a LOT longer than it should have, but i finally got it working but something strange happened...

I am running the latest oxygen rom (2.0 gingerbread) have an 8 gb sandisk sd card , and i partitioned 512 to ext4 and the remaining to the fat 32 sd card.

However, when i downloaded quick system info, my "total" for a2sd was 504 and free was "439". why is that? what happened to the remaining space on my card?

Dalvik cache probably
 
Awesome I checked it (The FAQ) and read the following posts but still didn't find a solution....what am i supposed to do or look for?. Thanks Dan!
 
Dalvik Cache is moved to the ext partition. There always exists some Dalvik cache. It is like the registry in windows. Apps settings for the OS etc. When you first boot into a new rom, it takes a long time to boot. This is because it is building the dalvik cache.

The main advantage of Apps2sd+ is that the dalvik cache is moved to the EXT partition, unlike Froyo's implementation where it stays on internal memory.

Basically, don't worry that it is not 100% free. It never will be. ...and everytime you install an app, it will go down.

Its normal.
 
Oh alright and thanks for explaining Dan!

I should note that i didn't flash a new rom after partitioning my sd card, but rather continued using the same oxygen rom I had running prior. Am i supposed to flash once again, or what?
 
If you already had an apps2sd Rom then that explains the used space also.

Install an app and see if the free space goesdown. If it does, then all is well
