[Q] Partition SD Card (different than previous questions asked)

First off, to eliminate the flamers 1)I know you don't need to partition your SD Card (i've been running android on 2 SD cards for around a month now) 2)I know it won't make my device run any faster.
The question is though If i partition my memory card to have the 3 partitons: ext, linux swap, and fat32, will this mean that on the main part of the memory card that my windows mobile can see that i won't have all of the various folders that the Android OS creates (i.e: .android_secure, .bookmark_thumb1, rosie_scroll?
The reason i ask is i want to have my memory card as clean as possible so that within my windows mobile build that it is still very organized.
Thanks for any help you can offer. If you are going to reply simply to say use the search, I have, I've read and thank you very much, you can now move on to the next topic to type that.

I also have the same question.
How get clean memmory card from Android folders?
Or how to install Android in folder (sdcard/Android/all android folders)
Than my WM folders will use (sdcard/WM folders)

I second either of these as to keep my mem card tidy from all the android folders created and mixed up with my WM files.

Well since no one seems to know the answer or isn't willing to share, I am going to try doing this within the next two days and will report back on whether or not it works.

How would each OS know what partition belongs to it?

Nice to hear that! I think there is 2 ways:
with partition on sdcard
change Android install place to place in folder
Somone who build Android roms can try to change location where android install apps.

If you crate partition for linux (ext...) windows will not show, read and find it.Also WM will not read files on linux partition but I think that linux still will read both. Dono how it is on Android but in Ubuntu on PC it works.

SD partitioning works great!
This is how to create partitions on your SD card: http://forum.xda-developers.com/showthread.php?t=267475
I tried it - and it works. WinMo shows two storage cards - 'Storage Card' and 'Storage Card 2'. The first one is the Active partition - which is my Android partition.
When you are in WinMo and installing WinMo software, you are given the choice of where to install it - and it shows both storage cards. So in effect you can have all that is WinMo on one partition and all that is Android on another. Android is working nicely from its own partition.
I must say - this is the first time my Android is working sooooooo well. As well as my wife's HTC Desire device. It is a noticeable difference - the same Android build worked quite sluggishly before this exercise. It is either because I am using a freshly formatted partition, or because it has its own partition now.
My partitions were formatted with FAT32, 32KB unit allocation size. I am using ChuckyDroid ROM and currently testing this Android build Core_Droid_V.0.2.
Yeey ! " ... after action - satisfaction .. "

[Q] NAND Builds and low memory

Hi
As I am seeing this issued being scattered evey where I thought i'd dedicate a thread to it.
Is there a solution to this??
I read some where that you can create a ext3, 4 partition on your sd card and and use that as system space also.
Is this possible with the HD2 and NAND builds?
This is the only thing keeping me from completely moving over to a NAND build.
Thanks in advance.

As its already been stated, this is currently not possible, there will very likely be a modified build/kernel or whatever soon though.
You can combat this problem by moving apps to sd once they have been installed using a program like Titanium backup or app2sd or another alternative.

Idea/thought

Hi guys Android development is evoluvating to new diamention.I have tried from Build from SD cards and RAM version and NAND ROM.The NAND ROM is better of all but the biggest disadvantage is internal storage.when many apps are installed 'memory is low' appearing.even after moving all movable apps to sd card using move2sd.some programmes use internal/phone memory like evernotes,copilot.
so my idea is can't you guys create vitual storage in sd for the NAND like the one we had in SD card based build.which is easy for portablity of data when we update.GUYS YOU ARE BEST DEVELOPPERS IN THE WORLD HERE

This might be useful for those with 512 version of HD2, or maybe even for 1024, and it should be pretty easy to mount file from SD same as data.img from SD builds.
But! The question I had is, do you really need to create thread with "Idea/thought" subject? Can't you call it "Increase data space for NAND builds" or "Mount data.img with NAND build" or something like that? It's cool of course to create "Idea", "Question", "Help", "Please" etc threads...

Hi dude,
the reason I created this is - it gives an idea to developpers to develop in their next nand to focus on more storage as you know new native phones have more than 1Gb internal space it goes up to 16GB. As I have mentioned some apps can not be moved to SD card. You may have different idea on how to open thread which is not nessesarily same to others. Give something which is useful to development of andriod on hd2.cheers buddy

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.
---- edit update:
this has gotten way off the original topic so I've started a new thread with a diferent topic here: http://forum.xda-developers.com/showthread.php?p=31356468#post31356468

[Q] Install android on internal storage without sd card?

Hi guys,
I have an old HTC HD2 and today i have been trying to find a version of android that installs on the internal memory (NOT on the sdcard, which I don't have). I think it has to be a DAF file? On several sites and tutorials I have seen people having some version of android installed on the phone, but i have been looking on here for a few hours now but I'm not able to find any... Does it still exist? I already task29 my phone so i think it's completely formatted and has no OS on it now, so If anyone knows a link to a android version that can be installed on the phone memory without sd card, it would help me a lot!
Thanks in advance!

I think those builds are still available, but you need to search in the very od threads. ANd you need to make sure it is Sense 1.0 because newer versions are larger so either you would not have enough space for user data or the ROM would not fit internal storage anyway.
