total noob
pretty sure it's not the developers fault of tazzsensefroyobt. because for a while it was working great for me. ever sense i tried to use apps2sd on PlainJaneT2_V2.0. i keep having an error on tazzsensefroyobt saying sd card is not mounted.
used rom manager to format sd card. then trying to fix this reformated using windows
There is a reason for that - the method to get apps2sd on a 2.1 ROM like PlainJane has you create a second partition on your SD card,to create a location to hold the apps. Unfortunately, Froyo will not mount an SD card with more than one partition.
You'll have to do these things, I think:
- backup your SD card
- do a Nandroid+ext backup from PlainJane, in case you want to go back
- follow the steps to partition your SD card from before, but choose 0 bytes for both the ext2 and swap partition sizes. This will erase your SD card
- go into the USB-MS option from Recovery to copy files back over to your formatted SD Card.
- Now you can flash the Froyo ROM you want
worked beautifuly thanks
apps2sd
so if i want to get rid of apps2sd on a 2.1 rom and just use for 2.2 roms just format with 0 on both swap size and ext2 size

That's correct. For some reason I think that there is one of the 2.2 ROMs that actually will mount an SD card with more than one partition, but I could be wrong about that, and I can't remember which one it is. But if a Froyo or Gingerbread ROM will not mount a perfectly good SD card with more than one partition? That's why - it has more than one partition.

Froyo and higher will work with multiple partitions; it's just not real easy. The trick is that the SD card has to be partitioned in a certain way.
From memory of the thread that's in the Dev section (I think the OP was Conap), the first partition has to be FAT32, and would have to be large enough for any NANDs and ROMs you want to ever backup/restore and flash.
Any other partitions can be anything you want BUT with this one rule. If you have a total of four partitions or less, then the last partition HAS to be FAT32, and will be the partition that'll be mounted by the AndroidOS when it's up and running. The second part of this rule is that if you have MORE than four partitions then the fourth partition is the one that has to be FAT32.
Just like partitions 2 and 3, anything from 5 and on can be anything you want. Conap also developed scripts to mount partitions like the first FAT32 one, since it's nice to have access to it from the running phone from time to time (mounting it through USB from Amon RA or Clockwork Mod should still work as normal). I think he also made ways to mount these other partitions from Windows. My memory is fuzzy. I only tried once to make this work for me, but I wasn't really successful mounting the oddball partitions to the phone or to Windows, and I didn't try real hard - I didn't care enough to really try to figure out what I assumed I did wrong, since I believe other people were able to test it just fine.
This theory of operation appeared to be developed in conjunction with the dual-boot AndroidOS 2.1/2.2 ROM by TeamAndIRC (I think they're called), which includes Conap and others as members. I never tried the ROM.
I'm not positive if the limitation of the partitioning applies to all phones with 2.2 or higher, though. I've read some threads for other phones that officially ran 2.2 in which they mention partitioning to be able to use old style Apps2SD instead of the native one, and there wasn't any mention of any complicated partitioning scheme.
Does anyone know enough off the top of their head to verify this?

I know Froyo has built in apps2sd that allows you to save part of an app on your sd and the rest is saved on your phone, which is great for stock phones who have only had the conventional internal storage available in the past. I really like the Froyo roms that are out and have been using them daily for a while now. Is anyone working on an apps2sd for Froyo roms that will accept a partitioned sd card? Is this even possible on Froyo? If not I'll just unpartition my class 6 card and use it again. I've already formatted it 3 times and I'm afraid I'll corrupt it if I do it too many times.

Developing a2sd for a ROM that already includes it would be redundant, yes? The question then becomes, "Do I want the benefits of froyo and not be able to partition my sd card, or stick with 2.1 and be able to partition the card?"

Yes. Cyanogen and the team at Cyanogen(mod) are currently working on this for Cyanogen(mod) 6.1. Their goal is to have Froyo play nicely with Linux ext4 partitions.
No one has successfully done this yet, and CM6.0 isn't even ready yet. But yes, so you know, this is being considered and worked on.

Yes, you want the benefits. Cyanogen is not working on this mod because "it would be easier to switch between Eclair and Froyo ROMs." The reason that team is working on it is because Linux ext4 partitions are faster and more efficient than FAT32 partitions. Thus, the phone's performance is increased when running both apps and cache from a Linux ext4 partition.
So, just for the sake of discussion, here's a tangent... What I'd like to see if a way to convert /system/data/ to Linux ext4! THAT would be nice. I read about a way to re-partition your vital systems files, internal cache, and internal data paritions so that the vital files are contained on a partition that is almost exact to the size needed to run those files, so that the cache is a relatively small size, and so that data is the remainder. This is great, because it eliminates the need for Apps2SD and unties the dependence of your phone from your SD card if you use a lot of app space. To get this as well as the cache folder (hell, let's do the vital system files to) into ext4 would be amazing and would greatly improve your phone's performance!
You just made my night.

Ok after many hours tonight I have managed to put together a couple .zip files that will install a modified vold.fstab on your Nook Color. (I am a total n00b at this)
The EMMC of the Nook Color has a partition for the ROM and a 5 GB partition that's mostly if not completely unused. Presently, there aren't any 3rd-party managers to move apps to that unused partition, so I modified the vold.fstab and am now able to use that partition for apps, files, etc.
NC.SWAP.VOLD.ZIP swaps the way the SD and EMMC directories are mounted. By swapping the mount points, and renaming EMMC to SDCARD, your apps, etc., will install to the internal storage, vs. installing to your SDCARD. Your physical SDcard is automatically mounted as "EMMC."
This also means that the music player still finds files, you can move files to "EMMC," and you can still eject the SDcard ("EMMC"), put it back in and it still shows up automatically. Now your NC won't freak out if you pull the card out without unmounting it - all of the apps are on the actual EMMC. You'd just find the SDcard under /mnt/emmc instead of /mnt/sdcard.
Because this ZIP file maps the change at an OS level, when you boot to recovery, your NC sees SD as the SDcard, so no issues occur. When you boot into your ROM, the mount points are swapped and you'll have access to the renamed "SDCARD" (5 GB) on your NC.
Use CWR 3.0.1.0 to install the .zip and check out the results with File Manager.
Thanks go out to Clark008, luciferii and Cali^Gal from #nookcolor, Loonacy and Raymondull from #Cyanogenmod, and EpicFail1236 from XDA.
Sorry if this is a bit crude, it's my first script ever. I would be happy to get any advice on how to make this better!
EDIT: I have been looking into renaming the emmc mount to say SD-External or better yet making it mount as /mnt/sdcard/sd-ext. it might be possible, ill be looking into it as soon as I can got laid up for a bit.

/\/\ That clarifies a lot compared to the brief orig post. Will likely be flashing it this weekend.
BTW, if this expands and you need this 2nd post just have a mod give it to you. Thanks again!
BRILLIANT. Will be definitely testing this later today. Can't wait to run SD Tools on this
Sent from my NookColor using Tapatalk
it works! interesting how it'll work out as to unmounting, flashing roms. but with emmc being useless this is fantastic.
Thank you for the effort and time place in this mod
Yeah. The whole point of this was to utilize the 5GB internal emmc and not waste it. The next step is to mod the CWM to mount emmc as /sdcard so you can flash your zips from where you download them to (usually /mnt/sdcard/download), which in this case, goes to your emmc. But CWM will mount your external sdcard instead. For the time being, we can just put the zips we need to flash to the external sdcard, ie. /mnt/emmc.
I don't know if anyone noticed it yet, but if you usb mount after the swap, the transfer speed is kind of slow (~1.5mbps). I don't know if this is due to the emmc or that the read ahead cache needs to be tweaked.
We're open to make this even better. Feel free to comment and provide feedback.
This sounds like a step in the right direction, however, what I would like to see would be merging the emmc with the internal storage. What I mean is this; right now, when I go into "Storage", I see an "SD card" (8gb), "Internal Storage" (0.92gb), and "/mnt/emmc" (5gb). Why can't we combine the .93 Internal and the 5gb emmc together to make a 5.92gb Internal storage and eliminate the emmc from teh storage area? I'm sure there is a reason that I'm not aware of, but it seems that this would be the same as just about every other device. I am pretty sure the ROM is running from the emmc partition, so that has to have something to do with it, but I don't see a purpose for 3 storage places. I keep getting errors when I try to download apps and I don't even have very many installed. I have had to move most of them to the SD card to make room and some apps don't like to be installed on the SD card.
Another option would be to swap the emmc with the Internal storage. Then we'd be using the 5gb and the .92 gb would be sitting there doing nothing instead. Again, I'm sure there are reasons for this, I'm just asking to learn.
I agree.. ideally having the emmc mount be part of the system would be ideal.

i have no idea TBH but thats far beyond my ability. really it would be nice to symlink emmc to the SD card or the other way around. the issue is that you cant symlink with fat partitions :-/

I just use my stock emmc for music storage and let apps sit on SD w/ videos.

No, but you can symlink to them. Why not set vold.fstab to mount the partitions onto other names and make symlinks named /sdcard -> /othername? That way, the symlinks can do their jobs or rearranging the namespace to suit our needs.
The ramfs isn't FAT32, is it?
I'm an old cmdline type, tricks like this are used all the time to fool software with stubborn opinions about filenames.

IMO, with a great write up on the best ways to work with this, all of the things it will affect (positive and negative), and the proper words of warning then the individuals that take it upon themselves to modify their devices are the only ones that can be held responsible if it doesn't work out as they had hoped.

This may be slightly off topic, but I cannot for the life of me figure out what that post is complaining/ talking about, I have had no trouble bouncing between HC, CM7 and stock.
All you have to do is flash to stock and then worst case you force the boot failure and the nook resets its self automatically
The last few posts on that message are myself and another person who have had not trouble with that now the OP hasn't responded so i'm not sure what to make up that post.
Is it real and an actual issue?
Or did the poster overreact to something?
Can some one please explain it to me if I am wrong about something in using a EMMC version of HC?

Seems neet to me also. Always interested in using both emmc and sd space.
@ chisleau - I like the concept of putting all my music on emmc. Do you use an option in CM7 to install or move all your apps to your SD card?
thinking out loud (and not actually doing it) -- but we know that /data is /dev/block/mmcblk0p6 and and the "media" or "emmc" is located at /dev/block/mmcblk0p8 -- can't we just repartition and merge the two?

Yep, I was hesitating, but between your post above and the "Thanks" from fattire to the OP, that is all the encouragement I need to take the plunge.
A few questions, tho, if someone can help me to understand this better....
I guess until I saw the OP, I did not realize that all apps in CM7 are installed to the SD card, as when I look at my installed apps in App Mgr, they don't show as being on the SD card. Is this some sort of CM7 voodoo or are my apps really on the internal memory?
Right now, with CM7, I am using the EMMC partition to store my music, under "My Files/Music". Power Amp can see this folder and it will play all my music just fine from within that directory on the internal partition, so if I install this update, what will that do to the 5Gb of internal storage I have now and the music on it?
Also, if I do install this update, what will happen to the apps and their associated data that I already have installed? Is this best done on a fresh build or will everything (apps/data and music) be A-OK after the Swap update is applied?
Just want to know what I am getting into by applying this update, as I have things pretty stable right now. If I could roll with apps on internal and music on SD, I would be more than fine with that, as long as I don't lose any of my apps/data/music in the process. If this is just mere partition re-naming/re-pointing, then I suspect my assets will remain intact?
Thanks to all who collaborated on this project!
why can't the entire internal partitions be imaged?
i use dd all the time to backup my sd card installs in case a test kernel or nightly goes poorly- or to burn a fresh install for multiple people. I just pop in the sd card into my laptop and burn the image back to the sd card.
if this was possible i'd have no issues with running off internal entirely if i could just burn the img. and get everything back as stock, including important device identifiers incase those were erased.
Need undo
This did what it's supposed to do but it seems to be causing a problem with the way I'm booting from sd. Is there a way to undo this?
Bump since I found this useful. +1 for CWM sdcard/emmc swap to enable SDcard-less flashing goodness from ROM Manager.
Has anyone got this working? I used to have Link2SD in 2.1 but now the ext partition is the only partition recognized by GB and not my main partition. I can access my main partition from USB connect, but not from within the phone. Anyone has the same issue?
You can natively move apps to the SD on GB in Options>Applications>Manage applications. Choose an app that supports it and the option to move to sd will be there. No partition needed.
Thx, i will just fix up my SD card into a single partition again then
Does this also mean that I don't need the app Apps2SD anymore?
With App2SD you can quickly indicate which apps can be moved to SD. So I still have it there. Furthermore, App2SD also quickly clean your cache.
Link2SD gave the option of moving ANY app to the ext2 partition. The native gingerbread app2sd doesn't support moving all apps to the SD card.
Any way of making link2sd work on GB 2.3.3?

@Anant: My SD is setup as per the guidelines described here:
http://forum.xda-developers.com/showpost.php?p=10711328&postcount=1
I have a 8GB card and I have allocated 7.05 GB of FAT32 memory to the Data partition, and have allocated 0.5GB to the secondary partition. This partition was also setup as FAT32 since i had issues with EXT2.
*Edit: After the 2.3.3 update, the X10 now detects only the 2nd partition (480MB) instead of the data partition (7GB) - but when I plug into a PC, the data partition gets mounted correctly.
Hope that helped.
That is not good, it means that you cannot transfer data or programs between your PC and the 7GB partition... is there a way to fix this?
When you plug into pc, your data-partition mounts correctly, so you can copy your data to your pc as a backup.
I recommend using a adapter to connect the sd-card to your pc, formatting both partitions, and then put it back. I did it that way, be it that I removed my second partition and went back to one partition only, 8 Gb, and all works fine now.
I don't intend to use Link2SD anymore, because in 2.3.3 the system can apply data2sd itself, I learned, with or without Apps2SD.
Good luck, greetz,

From my observation, the 2.3.3 android system moves the appdata to the sdcard only in certain large apps (apps >7mb in size?) which is good if you have are dealing with huge apks like AngryBirds, but not too handy if you have a huge number of small apps all ~3MB in size.
BTW the native app2sd isn't compatible with all apps.
Use "Move2SD Enabler" from Market to allow moving any app to SD.
https://market.android.com/details?id=com.leinardi.setinstalllocation&hl=en
This didnt work with my 32GB SD card... it is now a single 32GB FAT32 partition. What type of format should I use? FAT? EXT2?

@doomed151:
Thats what I was looking for! Good find!
This app has its own hitch though: the move2sd enabler needs lots of caution...some apps aren't supported, and moving them to the SD causes them to crash. There is no way of knowing which apps can be moved and which ones can't. I happened to move GT Racing HD to the SD and it stopped working. Had to reinstall!

@Anatshri Any luck on this? I would prefer to use link2sd instead of the native move2sd in GB.
I tried a 16gb & a 4gb sd card but couldn't get it to work. I've also tried ext2, ext3 & ext4 as the 2nd partition but I don't think the stock kernel supports any of them. The sd becomes unreadable after a reboot but if I connect directly to the pc I can see both partitions.
If I make both fat32 partitions only the 2nd partition gets mounted. Do you think this is kernel related as well or can we modify the mounting scripts to correct this?
I am suffering from bad health conditions right now so can't work much however all I can see right now is if this is the case you can do two things
1) create a script that mounts partition 1 at /data/sd-ext coz link2 sd needs mounted partition at this location. I suppose init.d script could help us. However
2) the problem would be that recovery will detect only partiton one

I move from 2.2 to 2.3.4 and link2sd don't work anymore cannot mount the 2nd fat32 partition.
App2SD sucks because doesnt allow some apps to get moved.

I agree with you and hope that we will have this possibility, I really miss link2sd, the best app ever to move apps to sd.
I'm using Shooter's ROM, everything is great so far.
I'd like to create an EXT3 partition for A2SD. I'm going to use Linux(Ubuntu) to partition the SD card.
When I did it on my Evo4G it was part of the recovery, Clockwork I think.
I found guides on SD partitions for other phones but none here yet.
Should I just use the suggested partition sizes and setup for the EVO 4G?
I have a 16GB card so I was thinking:
2GB Ext3 primary
14GB Fat32 primary, I understand effective partitioned size is smaller.
Also, should I be concerned about Swap?
Thanks in advance for the help guys
You might want to research this more, but I think that A2SD will only work correctly in Gingerbread if your partition is using EXT4, not EXT3... I'm almost positive about this, (and that's the way it worked with the OGEVO running gingerbread roms) but please check it out at least.

Hi, when i had a HTC desire, which had not a lot more internal memory than our phones, there was a script on one of the roms, DATA2SD i think it was called, after partitioning your card, the internal memory could go up to 2GB i think (well, on my 16gb card anyway), can this be done n our phones? and do any roms have this????
Two steps: 1) Format 2) Choose script.
First you need to format your SD card so you have a FAT32 partition (first primary partition) and an EXT partition as the second primary partition. I do this from the commandline, but the best option is to use CWM V5+ which automates this for you. Then there are several options for scripts which mount the EXT partition as a virtual internal /data/app/ directory
S2E is the recommended option if you use a cyanogenmod based ROM. It uses mount points.
A2SD is installed by default on ROMs that use ketut's kernel if I remember correctly. It uses a simple symlink.
Link2SD is available for multiple ROMs. It is the most "advanced" as it links individual apps rather the whole directory, but with more power comes less simplicity...
Ahh the Desire.....a phone that is still popular despite its age
