[Q] what's sd-ext?

i looked around the forums a bit but the search returns too many results not related to what i'm looking for...
So not really sure what this sd-ext is. I've read that it's for apps that are moved to the SD card... But the thing is i'm running CM7 and i've moved apps using Apps2SD as well as directly from within GB itself without ever creating an SD-ext partition.
So whats the purpose of this? Should i create the partition? And does it make a soft link to a directory on my SD card since it seems /sd-ext is in the root folder. If so, if i change my SD card later and transfer all the files over to it, will it break the link?

Your SD card has a fat32 format, which is mostly typical for usb storage devices, computers, etc.
Android runs natively in an ext format environment.
The stock Apps2SD uses the fat32 portion of your SD card, which has limitations, because it isn't Androids native environment. If you format your card so you have an ext partition, you can trick the phone into thinking it's part of it's native environment...
A good example can be seen with widgets, which won't work if you move them to SD, but will work on an ext partition. Other uses include being able to move cache and dalvik...

Thanks for the explanation. What happens to all the apps already moved to my sd card now? How do I get them over to sd ext partition?
And right now I only hasn't an eight gb card which I plan to upgrade in the future. Will I be okay just transferring everything over to the new card at that time?

You will need to be rooted...
You first set up the ext partition. Doing this will format your card, and erase everything. You will then need a script to run the a2ext. Darktremor is the popular one for the Nexus, but I'm not sure about the MT4G...
Once you have an a2ext script, then you just move your apps to internal, since the phone thinks the ext is internal memory.
Titanium backup can help backing up your apps, and also with moving them to internal in a batch...
Read up, because I know little about the mt4g specifics. I've ordered one, but until it arrives, I'm just reading...

Thanks. Yup I am rooted and running CM7.
seems to be a bit of a pain to format my sd card..

I must admit, I wouldn't think you would need to?
The mt4g has more rom and ram than my Nexus, so I wouldn't have thought that you would run out of space quickly... Or am I wrong, and space is an issue?

No you're right actually. It's not really an issue but not sure why I think I should move the apps to the sd.. Haha

Partitioning the SD Card? [HELP]

Hi guys!
I'm getting crazy....I'm using MiniCM7-2.1.9 + nAa kernel v11 on my X8.
But if i try to create ext4 and swap partitions on the SD card....android tell me: "it's possible to remove the SD card" and it won't mount it!
I have created: -1.4 GB partition (FAT32) (Primary)
-0.5 GB partition (EXT4) (Primary)
-70 MB partition (SWAP) (Primary)
Why it won't work?
How I can fix it?

Well, since you SD card is 2GB, try FAT instead FAT32. Partition and reboot. I have the same error, but one reboot solves.

Or make partitions on pc...have a lot off free programs for that

OK,tnx.
I've found another easy way, in CMW>ADVANCED>PARTITION SD CARD.
It seems work without errors, but I have a question, how i can install apps on the ext partition now?
I've in cyanogen Settings:
Application>Allow Application moving (enabled)
Application>Install Location (what should I select? automatic, external or internal?)
Performance>A2SD (ext) Settings> A2SD mode selected (is it correct?)

Or make partitions on pc,its easy

Hye, it wont work on minicm....you have to flash GDX first....dont reboot....just mount sd, data, cache, and system, after that make ur partition....done. then you flash back minicm...just try this first ok....gud luck

[Q] Link2SD not linking to SD Card 2nd Partition

I followed the tutorial by Sir CarlDeanCatabay to increase the Internal Memory by partitioning SD Card using Mini-Tool Partition Wizard. I first made my 2nd Partition as EXT4(as Merruk 2.5 supports EXT4), but, Link2SD was unable to mount script. I tried with both EXT2 and EXT3, but, the same result came. I saw another external tutorial which said to make the 2nd Partition FAT32; I did, and Link2SD was able to mount. I installed some Apps and LWPs, and Link2SD said that it was link to the SD Card. When I looked upon the Storage Info in Link2SD Menu, I saw my 2nd Partition as same as it was at first, but, my Primary Android-SD(it was set as Active during partition) was filled with 35 MB out of my knowledge.. Isn't link2sd linking my apps to the 2nd Partition and instead doing so to SD Main? If so, what should I do? Thanks!

I think u must prefer cwm method....as it is easy and doesn't creates problem

I wish I'd have done that, I've already partitioned...I'm also not so sure if it is linking or not..

Did you set your 2nd partition as primary?

yeah! I did set my 2nd partition as Primary and FAT32....since, Link2SD was unable to mount the EXTs...

Link2sd on AOSP?

Link2sd doesn't work on AOSP, is there a way to make it work?
I have partition that worked on other system but here it doesn't.

[Q] my hd2 only has 151mb of internal storage

why does my hd2 have 151mb of internal storage and only 91mb for installing apps. i have NexusHD2 ROM.:crying:

You have a 512MB HD2 (European). And most of that is taken by the system partitions and whatnot. You need data2ext or sth like that so that you can have more storage.

create ext4 partition on your sd card using mini partition tool, it will increase your internal memory.
Hit thanks if it helped :laugh:

it's normal that you have only this storage memory, Nexushd2 ROM are consuming a lot of memory.
You can move your apply on your sd-card if you have one or you can do that Rahil S say.

but i dont know how to create an ext4 partition on sd card, can someone please guide me through on how to do this.:crying:

I'm sorry, you will have to look for that yourself.
You can use the link in my signature, it's an HD2-specific search.

So when the ext partition is created, will some of the internal memory still be used up by apps that are on SD.
Sent from my NexusHD2 using xda app-developers app

When you create an ext partition, it becomes the internal memory for apps. No need to move anything to SD.

Yes but i have created ext partition of 1gb, yet I still get low memory message. I used titanium back app.

You reflashed the rom? And chose Dataonext?

i just created an ext4 partition of 1gb on the sd card using cwm. like rahil s indicated

No. Even after creating the ext4 partition, data and apps won't move on their own. You need to reflash the rom with the option "DataOnExt".
You can use TB to backup your apps, and restore after you re-install.

Is there another way, cause I don't want to mess around with the flashing stuff as I have bricked my phone in the past. I mean is there an alternative to flash like partition the SD card and use app like link2sd to move app data to sd

Sorry for getting in the middle of your conversation,
but i believe that the best solution is data onext that it was stated above.
Tou should really give it a try!

Are you looking for 10 posts also? Because we've already agreed that DataOnExt is the best option. He DOES want to give it a try, so your post is pointless = You are looking for 10 posts. What's the sudden interest in the HD2 section for spamming?
Also, NO. Your apology for interrupting this conversation IS NOT acceptable.
Anyway, @OP:
I think the best option is to back up all your apps using Titanium Backup, reinstall the ROM with DOE option, and then reinstall TB and your apps.
No, using Link2SD will not help you. It doesn't work like that. Sorry.

go to market and dowload link2SD to link or move app to SD ext or

u have a 512mb htc hd2 so only u have internal storage problem it is not a big deal.......first make a ext partion in sd card so u can use in two ways the ext partion:
1)for instaling native sd build(have more storage depend on how much u partion sd card ):highfive::highfive::highfive:
