partioning sd card for apps2sd - EVO 4G Q&A, Help & Troubleshooting

how do i do it
i booted into recovory mode
and clicked partitions menu
but i dont see partition sd card
just format sdcard

Not following the previous, but related
Rom Manager gives me the option to partition my sd card, but informs me that will wipe my card. I have Titanium backup, but I assume the backups are stored on the sd.
I am being cautious, which is probably causing me to ask a noobie question of offensive ignorance, but is Titanium backing up what is already in my ROM?
If so, no problem on the repartition, just back up again after reformat...
Next question: what is the best suggestion for partition size on an 8 gb card? And What is the best swap size for performance?
Thanks for any answers!

Undo A2SD

Hi,
Does anyone know how to undo A2SD? ie move all the apps back to the internal memory then remove the ext3 partitions from my memory card?
I'm running a rooted 2.73 ROM with RA-HERO-v1.2.2 recovery image and a vista computer
cheers
I'd also be interested in this, I often get a message saying something like 'sd card maybe not inserted or full' (cant remember the exact msg atm) which I think may be related to apps2sd. Couldn't find any info on the message though.
I'd solve it like this:
Step 1: Format SD card (thus also wiping all partitions)
Step 2: Wipe and re-install any rom - to avoid problems with dependencies from your old setup running with A2SD.
but then you lose all your apps!
He wants first to put his apps back on his phone and then he will format SD card.
But how? I want to know that also
1- Backup your apps using AppManager.
2- Copy the FAT32 partition content to your PC.
3- Format your SD card entirely to FAT32 erasing the EXT3 and SWAP partition.
4- Copy contents back to your SD card.
5- Install AppManager.
6- Restore Your Apps.

partitioning the sd card

I partitioned my sd while in recovery, I did 32mb swap 1024mb ext 2 and the rest fat 32. I then did the ext2 to ext3, then did ext3 to ext4 in the hopes of getting app2sd to work. but now all my nandroid backups are gone as well as everything I had on the card. when I boot into recovery and do msusb it has nothing in it and if i try to do a restore I get an error that says "E:couldn't open directory /sdcard/nandroid." I can still boot into roms if I put it on the root of the sd card, and i can still use root apps and if i use a file explorer in android the stuff on the phones internal rom is still there, so i guess what im trying to ask is what the heck did i do by partitioning the sdcard?
It's weird that you weren't notified, but partitioning the sdcard for app2sd is SUPPOSED to wipe the sdcard. But it IS a bug if it didn't warn you all data was going to be erased.
I had the same issue last night, luckily I figured partitioning "might" lose my data so I backed it up on my comp first.
Well I was right, it totally wiped the card. Glad I made a backup.

Migrating to a new (bigger) SD Card

I know this must sound like a super-noob question, but there's a simple reason for that : it is from one.
I have run out of space on my 8 GB card so I am thinking of upgrading to a bigger card. Here are my questions:
1) If App2SD+ is there on the ROM, does the phone ask you where to install the app or it goes automagically into EXT partition?
2) I want to make a bigger partition in a bigger card and will do it via ROM Manager. Do I just copy the contents of the older card and paste it onto newer and everything will work fine?
Please answer, my life depends on it.

I just upgraded from 8 to 16 myself. 1 : automatically, 2: yes that worked for me
best thing is to pre partition the card before putting it in your phone, do a nandroid backup with your old card in, put the new one in and restore, if im not mistaken this deals with the ext partition files and then just copy all the files onto the fat32 partition from your old card
not worked for me ,I was copy to PC old cadr,have nandroid but I have A2SD+ ext part
& problems ..stock with HTC white logo ,after that I make full wipe/factory reset
& after that instal the LeeDroid rom /put again ROM manager & make ext 3 partition/
after that Titanium backup & Desire functionality was back again
hi there i have auraxtsense rom and and i have an old sd card with app2sd i bought a new card for my desire 8gb class6, and my phone stuck on htc logo screen when i put new card inside
As said above you must re-partition your new card first!
I have just done this yesterday so this is what I did:
1. Nandroid backup
2. Create EXT partition on new card with G-parted Live
3. Copy contents of old SD card to the new one (just the FAT partition visible in windows etc)
4. Put the new SD card in the phone and boot into recovery
5. Restore nandroid backup (copies all the apps back onto the EXT partition)
6. Reboot!
I can't see how you could have any problems by doing what I did. The phone will not have any problems as all the old files are exactly as they were.

how to create ext partition with gparted?
You must first resize the FAT partition and then create a new EXT partition in the newly created space.
This may be helpful as there are some pictures:

Hope that helps.

So the Nandroid backup is not saved on to the SD Card?
EDIT: Ignore this. Wanted to know if it was on the FAT or ext3. I'm guessing on the FAT so nandroid backups would be included in the transfer.
What is the best tool for copy the entire contents of a memory card? I know Windows is a bit funny, stops the whole process if it finds an error, for example
Yes if you copy the files over before the nandroid then the nandroid backup is included.
TBH I just used windows to copy them all and had no problems.

One question - can the ext partitions have different sizes when restoring with nandroid?
Example - I have 1 GB ext on old card and now I'd like to have 2 GB?

Don't go larger then 1.5GB on a ext partition. Nandroid restore doesn't mind if the partition size changed, until the restored size is smaller then the new capacity.

You sure can, I just did it today, old ext2 w/ 512MB on 2GB card, now 2GB ext3 on 8GB card. Working just fine

I didn't say you can't, I stated that it's not recommended by the community to go more then 1.5GB. It was in all a2sd how-to's I've seen, has to be something about errors with the Market and app installing.
From what I understand the only advantages to APP2SD+ is that you can plug you can mount your card via USB and use your apps, and widgets can be installed on the SD.

This doesn't seem worth it for all the work reformatting another partition. If your card is upgraded to a bigger size why not use the normal method of installing apps on your SD? Why bother to partition with Ext+ as well?

Hmm, because it is what custom ROM requires?

Development Idea

Well here is my idea. Could we possibly partition the FAT32 part of our phones into more then one partition.
Saying like we could have a few FAT32 based partition, A Primary, One for roms/patches, then etc.
That way when we format the primary, it doesn't delete the roms we could flash. So we didn't need to hook up the phone to the computer to copy roms back over.
I know Recover firmware would need to support this. But it's just a thought.
I'm not really an expert at this, but doing a full wipe and installing a new ROM doesn't wipe the contents of your SD Card. Are you saying partition the phone's internal storage? What's wrong with just storing the ROMs on your SD card?

I meant like partition the SD Card into multiple partitions, So when you erase the SD:Ext and the FAT32, the ROM Partition doesn't go with it.
So example
SD:Ext - Partition 1
FAT32 - Partition 2 (Default SD Storage)
FAT32 - Partition 3 (ROM Storage, Backup Files)
So when you partition the SD Card though the Recovery it will only format Partition 1 and Partition 2, So if you left somewhere wtihout your computer and tweaking your phone, You could use partition 3 and access your ROM files and backups without going though loops for them.
What recovery are you using. I'm still not sure what you are talking about? I have no problems accessing my roms and kernels. You can do it plenty of ways and not do what you are talking about..
Use root explorer. Can transfer from download folder or if you made a certain folder on SD card for them you can copy paste them to the root directory on SD card if you use RA recovery. Clockwork you can go through every folder looking for the zip using clockwork unlike RA recovery which needs it to be in root of SD card. Your making it hard on yourself..
Why would you want to wipe fat32 and partion?

[Q]SD Card SD-EXT Dissappeared[Q]

I have an 8GB SanDisk MicroSD, it had a 500MB SD-EXT partition made using ROM Manager with 0MB of Swap. I was using OpenDesire, the latest version.
However I decided to change to Cynanogen 6.1.1, as it is more stable. I decided to Un-Mount and Format my SD Card, as I know this wont format my SD-Ext. After Formatting my SD Card wouldn't re-mount so I connected it to my computer, and formatted it again, by right clicking and clicking Format in My Computer.
After doing this it said I had 7.86 GB of Memory on my SD-Card. This is how much is left on the SD Card with no Partition's or data. After I installed Cynanogen, when wiping the user data, I noticed that it said there was no SD-Ext partiton, and so it couldn't format it. I immidiatley went back to ROM Manager to create one, however when it gets to the Clockwork MOD Part I just get a error about a signature or something? Can anyone please help - thanks!
Perhaps the format option under settings wiped the whole SD card and repartitioned it with a single FAT partition, therefore deleting the EXT partition. Format from within windows/linux in future. AFAIK, there would not be an ext on a stock rom and therefore no need for one, so the format option just goes ahead an obliterates.
If you've got a nandroid you could just repartition and restore.
Sounds like it just formatted the whole thing into a single partition. Just partition it back again as your really suppose to do when switching roms.
