MyT3G 32B SD CARD EXPERTS?

I'm trying to get expert answer what should be the right way to partition sd card of 8gb class 4 for mt3g 32b. Some developers are saying that fat32 is good enough, some are saying that we need ext 3 and swap, some are saying that swap slows down the performance ? I'm just not sure what is the right way ?

Depends what Rom you running, really. Linux wise, an Ext bigger than 1GB is a waste. i dont think the OS can use more than that. 512 is adequate. As far as swap, unless you are using a Rom that takes use of it or run a script to implement it. Its was a waste as well. As far as ext3 to ext4, i would recommend googling it or looking it up on wikipedia. I currently use ext4 with the cyanogen roms since i read that is the way he has his dev phone set up.

Being a newb SUCKS!

Ok so.. I finally after months flashed my second rom
HAd some trouble, I have to admit..
DC~~
I had trouble and I did some wiping and messing with my SD chip and that was the only way I could functionally get a flash..
I just spent a day and a half setting my phone up to my liking and its become apparent apps2sd isn't working and my SD card only has one 1.5 partition out of 2 gb.
Sorry if there are posts with directions of how to work from this point to keep everything while enabling apps2sd and transfering
I dont know where to start searching.
Thanks guys.

get a app called dconfig, it has an option to move your apps so they're on the card.
other than that im not sure what youre asking.
it might be simpler just to flash your phone, format your card and start from scratch.

do some searching on here, goggle & ppcgeeks for how to root, flash a recovery image, partition your sd card and flash a rom. just make sure the guide you are using and the rom you use is for a cdma based hero.
http://forum.ppcgeeks.com/showthread.php?t=90380 heres good guide to get you started.

I'm rooted I might just need to flash the Rom with the SD card.formatted correctly... I'm going to try to re find where the apps are stored and save them... id love to just be able to correct my SD config and set up apps2sd and move em over so I can keep my home screen set up as well as the info supplied in my apps and todo lists..
Thanks for the info ... on the road right now (passenger.seat )
Maybe I'm not a newb, I'm just stupid... I rooted using ubuntu karmic and I had apps2sd working before I moved to damage control

hmm.. Damage control rom comes with Dconfig and it has apps2sd enabled and move apps to sd checked.
Ok heres the thing..
I had a Modaco rom before and with apps2sd enabled and the SD formatted properly.
Plugging my phone into a computer would open up 2 drives... One 1 designated to be 1.5 gb and another .5 gb
How ever now I only see one.. the 1.5 gb
My memory is running low as if everything i've installed is in the phone.
searching through the phone i can't seem to find where these apps are being saved...
Are they on the elusive .5 gb partition I can't seem to see??
i think not... I just rebooted and my available space is 63.74mb
It's all becoming a no brainer that i should reflash the rom with the correct specifications to the SD chip...
But what I want to know, is there a way around this. ( I don't see any options, but I'd love to reformat my SD correctly and get apps2sd working on my own, moving all my apps over there while keeping any stored data intact...) <--- is this possible??
[maybe i should learn how to communicate clearly LOL]
For the moment, Ill back up my SD contents and hunt down how to partition correctly.. then I'll see if I can't find the folders where it is storing downloaded apps... then I'll disable then enable the apps2sd setting in dconfig and download an app... if all goes well i'll start pushing my apps over and do the whol "fix apk uid" in the recovery menu...
Hell maybe ill even decide to get a newer recovery besides 1.2.3 while im at it hahah.. any suggestions would be appreciated

# cd /data/app
# pwd
/system/sd/app
# cd /data/app-private
# pwd

So... Why is my memory so low???
I'm about to take my SD chip out and see if I cannot access the contents of these folders without it in...
MY APPS2SD IS WORKING AND HAS BEEN WORKING
Sorry guys... somethings just up[or rather DOWN] with my memory and my SD card reads differently...

There's only one way to stop being a n00b: Learn.
You're doing fine. My suggestion is to not take it all on at once. Focus on one problem, fix it, learn from it and move on to the next one. You'll be a pro in no time.
I would guess that you need to repartition the SD card when moving from one ROM to the next, but I've never really played with apps2sd. See? You know more about it than I do!

download app: quick systems info
to see if your a2sd is working and how much is being used.
use the dconfig to make sure you have dalvik cached moved to sd... reboot the phone.
i am guessing at this....
you say you had a2sd working before with Madaco and could see 2 drives... that sounds wrong to me. if a2sd was working, then you should not see the 2nd drive. you are only able to see the main larger drive and that is it.. the others are used by android and not available to us.
now that you can not see the 2nd drive. sounds like a2sd is working. the app i suggested should confirm for you.

I did get everything working and my memory remains the same when I install applications.... perhaps I could see the second drive because I'm running Linux and/or the way I formatted the sd or the extension...

I think what you are describing is your SD-EXT partition (the a2sd partition you made). If you have a 2GB card and partitioned your card to be .5GB EXT, then it will appear your SD is 1.5GB. You get what I'm saying?

I used to be able to see 2 partitions as well. I think it was only with 1.5 ROMs.
If you want to mount both partitions then all you need to do is reboot into recovery and select the USB mount. Then both partitions will show up.
But you really don't need to mess with that second partition. Go to the market and download Titanium Backup. That will backup all your apps and settings. Restoring is a little annoying to do since you have to click for every app but if you buy the donate version then you don't have to do that.

I perfer Backup For Root Users... does the same thing but is free and is one-click one-shot deal.

Well I just rooted, and of course I have some questions..

Nothing too big. I've searched everywhere on this and apparently this is supposed to work, but:
I can't get Live Wallpapers to work
and I can't get the Nexus Launcher to work. Both of these just force close.
Oh, and how do I use Apps2sd? Its greyed out in the settings menu and I can't touch it. Thanks in advance.

All of this has already been answered. Just search the thread of the rom you are using. I promise, its in there.

Thanks haha. Should've done that. But I didn't get anything answered on the Nexus Launcher. It just keeps force closing. Would you choose ADW or Nexus?

Hey Nikolai, what ROM did you use? I've been really busy with a new job and didn't want to get crazy after (finally) rooting, so I went with Ivan's 1.0 ROM. It's essentially the basic Verizon setup without the junk, and overclocking. Apps2SD doesn't work...grrr.
I'd like to try something with Apps2SD and Live wallpapers, but I don't want anything buggy.

Launcher Pro is a lot faster than both of those. I would choose that.

im just wondering. now that im rooted what specific apps do you guys reccomend? i have Fresh Rom installed with overclocking just curious what other utilities i should get

A2SD has to have the SD card partitioned. You can do this in the Recovery menu where you flash new ROMS. It will erase everything so make a backup of what you want from your SD Card first then in the partitioning setup it ask for a swap and ext3 size default it is 32mb for swap and 512mb for ext3. After that you should be able to turn A2SD on.
If you choose, and shortly after you turn A2SD on you will, to stop using A2SD repeat the same steps for partitioning the SD card but when you are asked sizes scroll the track ball down till it is 0 for both swap and ext3.
I don't like it because I don't feel like buying a Class 4 SD card or higher to make it worth while. If you are using the stock SD card you got with the phone it will make your phone boot slower and take longer to access the Apps.
I don't know what ROM you are using but the KaosFroyo ROM is a great ROM it is small and that will save you more room for apps if that is what you are looking for.

this thread has nothing to do with development for the eris. can someone please move this to general?

I think I know why apps2sd slowed down your phone. You selected 32mb for swap. I selected 0 for my swap and it's been fast on every apps2sd enabled rom I've used. I bought a class 6 sd card thinking it would make my phone even faster but that was joke. My wife's Eris has the stock class 2 card and I can't tell a difference in the speeds.
I also agree with LexusBrian400 above. Launcher Pro is my favorite launcher. Play around in the preferences for a bit. It has some cool options.
snyluc13 - You need setcpu (or some other app) to control the overclock. Do not set on boot until you have found a setting that wont lock your phone.

Without some trickery and some tweaking, you can either get nav(maps version) and no lwp or lwp and no nav (working that is)

[Q] SD Partions for SD CM BOOT

Ok, I have run this install method 2x today http://forum.xda-developers.com/showthread.php?t=1000957&highlight=verygreen+sd+bootable *VeryGreen*
Now, I am not new to rooting but haven't been keeping up with my nook as I passed it on. Went from CM7 stable to MIUI couldnt' stand the market issues and didn't want ot deal with removing the up dater..blah blah blah ok enough of that
I have followed the instructions and was have booted CM fine but each time I look at my SD card I only have the one partition. Should I be partitioning it myself before doing the steps metitioned or should the install make the partions for me then I just write the FAT or FAT32 (<---top of my head) myself post install.
I wanted a dual boot but figured I would wait for CM9 to come out and wanted to test the SD install. Also, the system seems laggy and I would attribute that to the card i'm using but was also wondering if maybe it was from the partitions? I believe the card is only showing 120 mb used and 14 unused.
Thanks, for any help I have been working on this for 3 days different scenerios and used searches but I get so many dated threads.
~D

If you are using windows you will only see the first partition.
Sent from space

That would be why, hadn't thought about that but was going to into partitioning i myself this evening in linux either would have seen this or been worse for the wear. Thanks, seems it's still not running as smooth and I am thinking it' the card, I'll just got with old faithful for now and work on it more after NYE have a trip coming up and would rather have it in state I know works.
Cheers

HD2 WP7 and Android Dual Boot File Swap

I apologize if this isn't in the correct forum. I wasn't sure since it's dealing with two dif os's.
Anyways, my question is Can I access files on the android jellybean partition from inside of wp7? I would like to be able to play movies, look at pics in wp7 that are in the android partition.
Also, what about vice versa? One last question. Wp7 seems to run very quickly, but Android seems to run pretty slowly. I assume its because it's running from the SD card. Is there any way that can be sped up to run at normal (fast) speed?
--- edit:
is it possible to put android on the nand, and wp7 on the sd so that the android os would be faster?

So.
Yes, you can access files from FAT partition on WP7. Few file explorers allow you to do that, just have a look at them and check if Storage Card folder works. They also allow you to watch videos, view images and play music, but forget about playlist support, subtitles or anything complicated. We don't have software to do that yet.
Vice versa is not possible since WP7 uses its own file system which Android can't see nor use.
Android will always run slower because it's an unoptimized piece of sh- I mean software. But you can try ROMs which take advantage of EXT4 partitions using NativeSD method - these are noticeable faster, no more waiting for minutes for apps to launch. You can also overclock CPU and use higher read ahead value for SD card (SD Speed Increase from Market).
Putting Android on NAND and WP7 on SD is not yet possible. It might be when Magldr 2.0 will be released (and it won't be really that anyway), but we don't know when.

thank you
thanks for the detailed and thorough explanation. i see that you are also using a dual boot. how slow/fast does your paranoidjellybean operate? i'm going to look into ext 4 and cpu boosts. i guess i will have to reinstall/delete everything in my android partition to do an ext 4? and i guess if i go ext 4 wp7 won't be able to read it? i'm going to look into it. i will update this with whatever info i find.
---- edit
I'm going to try and use the roms you name in your signature area that you are using, and see if it works any better. what sd card are you using? I'm using a micro center micro sd class 6 16gb one. i'm getting a 8000ffff error in this wp7 rom when trying to get something from marketplace, and the droid is too slow. going to try the ext method for the droid. (can't dl apps on droid either!) so i will post what happens here.
---- edit
ok, i'm thoroughly confused by these instructions (somewhat vague in parts ) http://forum.xda-developers.com/showthread.php?t=1869673 Is there a video tutorial where it is shown what to do step by step to get a native sd setup for a dual booth with android sd and wp7? Do I just do it the same way I did before (install wp7, then reset / repartition, but instead of using fat32 i make a fat32 (how big) and an ext4 (or 2?) and which comes first (the fat or the ext) ? Afterwards, ALL partitions are primary?
i found this info for installing ext4. but do i create the ext4 BEFORE or AFTER i install WP7 ?

I'd say Paranoid JB is pretty fast using NativeSD (EXT) method. You will need to create an EXT partition first, but keep a FAT partition, because on EXT the ROM will keep only its own data and apps, the rest is still on FAT (just like now, but instead of data.ext and system.ext in ICS folder there is a partition just for those). Windows Phone 7 will not be able to read content of EXT partition, but it will not be needed, since there won't be anything worth looking at and all media files you will still keep on FAT. You will also have to make a backup of everything on your FAT partition because it will be lost, and fresh install will be necessary. You might want to backup your applications with Titanium Backup though.
For more information on partitioning please visit NativeSD thread.
I'm using a 8GB Transcend Class 4 card with 4GB FAT, 1GB EXT and rest (2.4GB) WP7FS. I don't have any errors with downloading apps on neither WP7 nor Android. Are you sure you entered that special code for Marketplace and logged into Google account on Droid?

furthermore
actually, i installed the hd20 rom you're using and had no problems with marketplace. at this point i have hd20 wp7 set up, activated, and working. i'm just trying to understand some of the more advanced information in the forums about setting up the ext4. i found some very technical instructions (edit: http://forum.xda-developers.com/showthread.php?t=534714 ) for setting up an ext2 with gparted via dos then upgrading it to ext4. i don't know if that will mess up the wp7 partition, and if i should have done this before i installed wp7.
i had already read the nativesd thread, and the extended threads from it. i'm afraid i'm just not knowledgeable enough currently to fill in the gaps of information i find in a lot of the instructions. but i'm not giving up.
