I am trying to partition my SD with 4EXTRecovery ready for the SuperNova ROM but not sure which options to choose. So I know I go down to 'advanced', then 'Partition SD Card'. Do I answer 'Romove all partitions and start from scratch' or 'No - save my fat32 partition'? I was thinking the second. Then 1st sd-ext should be 2048 or less I think. I'm not sure what to select for 2nd sd-ext (think it should be 0) and then swap partition. Haven't gone further than swap partition so don't know if there are more to select.
Thanks, Tony
Make from scratch if you dont have any important files on SD, if you dont format fat32.
1GB ext3 should be absolutely enough, you will never fill 2gb with apps lol.
Second ext select 0, no swap either.
Thanks. That's what I kind of thought but wasn't too sure. It's ext4 though, not ext3. I will go for 1GB as well thanks. Is it possible to change the size of the ext4 partition later without losing data?
I've just gone past the swap partition step and it asks 'Write partition table?' Should I answer 'Yes' or 'No'?
AFAIK yes.
I've just added a question. Do you know the answer. 'Write partition table?' Should I answer 'Yes' or 'No'?
Select "yes".
Thanks. Now to install the ROM. Fingers crossed.
Dont forget to full wipe/factory reset & dalvik cache wipe also turn off signature verification.
Just followed the instructions on droidzone's website and it all went smoothly. Now running SuperNova. Just took a while to restore all apps using titanium.
Thanks for your help and obviously thanks to droidzone for his fantastic ROM.

Ok so I'm on a g2 using 4ext recovery to partition my sd in hopes of enabling swap. I'm using Virtuous Affinity so it helps.. anyhoo.. I'm totally lost on what to choose for the sd-ext partition and then the swap. There are options to pick from -128 to -4069 to pick from for sd-ext and then 128 to 1024 for swap. Ive done this once in clockwork mod recovery following a guide religiously. The only reason I switched recoveries is to switch my system, data and cache files to 4 ext to improve speed on affinity. Now I wanted to repartition my sd to "properly align it" and enable swap for speed when I was met with way more choices than I found in CWM.
if you don´t plan to use sdext, format it to the lowest space possible. for swap i would say 250 are enough...
hope this helps...

Ok, sdext is partitioning you sdcard right? like splitting or dividing it? And If I wanted to enable swap dont you have to partition it?
if you want to enable swap there are two options:
1. you do make a swap partition on your sdcard (you will loose you sdcard content doing this) and enable it through the script as described in the guide i posted...
2. you download swapper2 from market. it´s a app that makes a swap file (you do not have to partition your sdcard and won´t loose your content) but you will probably get problems with usb storage

I'm trying to install m2sd on cm7. I do a full wipe, install the Rom, gapps, and m2sd script. After starting up I enable m2sd for apps and reboot. Then I start installing software, but they take up space on internal memory. After moving them to sd they don't go to ext partition but to the fat one.
What could be the issue?
how did you partition you sd card? should be done with gparted (step 5 here) or 4ext recovery only (not minitool or clockworkmod recovery).
depending on the options chosen for m2sd, some stuff will still take space on internal, for instance app data is best left on internal for performance. use an app like 'diskusage' to browse all your partitions.
make sure you're also s-off and on cm7r2 hboot to maximise space (have a look for further guides if this doesnt make sense).
Try also enabling dalvik cache to sd.
Or the data + r-mount combination (which is I'm using now with no problem at all).

I just did it all again, to make sure I used gParted, so I'm sure I have 10gig Fat32, 4gig EXT4 and 256meg Swap. Then I did a full wipe of the phone, installed cm7, gapps, and when the system booted I installed and configured m2sd APK and rebooted. Still, in the gui section you can see "File System Type: N/A". It looks like it didn't recognise the FS but I have tried setting that to auto and EXT4
EDIT
Does anyone know what a2sd script has been used in THIS rom?

4gb ext4 partition is too much, you won't even need that much for apps! absolute maximum that i've read you should use is 2gb, personally i recommend 1.5gb.
you also don't need swap.
both partitions also need to be primary as per the guide.

that rom uses terminal emulator to enable A2SD. follow the guides/instructions in that thread.
Currently running MikG3.11 w/a2sd so have a EXT3 partition for data (I have my /cache pointing there also). I'm looking to move to a JB rom (probably Evervolv - http://forum.xda-developers.com/showthread.php?t=1961602).
How do I need to re-partition my 16G sd to make the most efficient use? It's been quite a while so a quick 'step1,2,3 howto would be great..including suggested sizes, ext3/ext4...)
Recovery is SmelkusMod..
Thanks Tons!
You may not *need* to do anything out of the ordinary.
If your ext3 partition is of a reasonable size, you might be able to just wipe everything (except 'SD card') in smelkus, flash the ROM, and proceed from there. Nandroid first of course.
'Reasonable' means about 512 to me, others may have different ideas.
How big is your ext partition?
The main reason to repartition is if you are having mystery SD card issues or you want to add or resize partitions. If these don't apply, just wipe, flash, and go.

I would. Repartition, 0/1024, ext3, then ext4....i actually do this before any flash. Think about what a2sd does, and you'll realize that if you don't format, your system has to run through more dead data to get to the info it needs

/system 318 used out of 350mb

sdcard ext3 .97 used, 1.79GB total.
sdcard fat32 (rest of the 16G)
I had thought that going ext4 was typically recommended for JB. Are you saying first create a 1G ext3, then the rest as ext4? How does that work for transferring files back and forth via usb to a win7 box?
I intend on doing this fresh.. ie, install gbapps and individual app re-installs from there.
I have a lot of opinions on this but let me just try to answer your one specific question about ext4.
(going from memory here, I'm sure someone will correct me if I'm wrong..)
When creating partitions in recovery, you will be prompted to allocate space to three separate partitions, swap, sd-ext, and 'the rest'. You have to choose a specific size for the first two, the third partition gets whatever is left. If you choose a size of zero when prompted, it will skip creating that partition.
So if you follow jwitts advice above, you will answer zero for swap, then 1024 for the ext partition.
This will skip the creation of a swap partition and create a sd-ext partition with size 1024. Initially you want to format this as ext2.
The rest of the SD card will go in the main sdcard partition and will be formatted as FAT.
As a last step you convert your ext2 partition to ext3 (and if you think there would be a benefit, you can further convert it from ext3 to ext4 in a subsequent step.)
Honestly, I installed evervolv over the exact same partition scheme you have already and have seen no need to tamper with it. Obviously others do. I leave you to make whatever decision you feel most comfortable with.
Partitioning is destructive: you lose all the contents of the entire SD card in the process so you need to make a backup first, and I don't mean nandroid. To me it's a bit more inconvenience plus the risk of losing irreplaceable data (ie pictures, music, etc).
By contrast, wiping partitions is routine and doesn't touch the main FAT partition. If you use smelkus to wipe your sd-ext partition (as implied in the oft-repeated advice to "wipe everything except 'SD card'") you should be starting with a pretty clean slate.
Maybe I've had the wrong understanding all this time, but I have been working under the assumption that "wiping" has the effect of deleting all the files below certain mount point.
The contents of your sd-ext folder are just as gone as if you "formatted". There may be other benefits to additional formatting or partitioning, and when you are planning to start from scratch, that can be a good time to do this sort of "preventive maintenance", but I was just pointing out that under normal conditions it is not strictly necessary.
Seems I've made a bit of a booboo somewhere. I was recreating the ext3 partition on my sd card. I deleted the existing ext4 partition and resized the fat32 partition to take up the slack left behind. When I checked the partitions afterwards, everything was fine and all my files were present and correct in my fat32 partition. I booted into recovery, formatted all partitions except my fat32 and went to install my rom again. Except I forgot to put it on the sd card. So I copied it back on to my sd card, stuck the card back in the phone, booted into recovery and promptly got a message that pb99diag.zip is missing. I've checked the entire fat32 partition and there's no sign of it. I tried renaming "OTA_Bravo_Froyo_HTC_WWE_2.29.405.5-2.29.405.2_releasedauhl6jhok5cmdm6.zip" to "pb99diag.zip" but it doesn't seem to like it.
How can I get back into recovery without the pb99diag.zip?
found a similar thread: http://www.modaco.com/topic/348778-hboot-looking-for-pb99diagzip-why/
It's because you resized it, I believe it might eventually stop searching for the file and go into recovery, but it's not ideal.
I'd try backing up sd again, and completely reformatting and partitioning again, but using up to date gparted instead.
- Also, why did you need to change from ext4 to ext3? ext4 is marginally faster, most ROMs support ext4.
- And are you trying to install an RUU? In which case you don't need an ext partition at all?
Sorry just trying to understand your overall aim...

I had 2 2gb ext partitions, ext3, ext4. I didn't need 2 so deleted 1 and just created a single ext3 partition. I wanted to go back to my PA jb 4.2.2 which was working fine until I used link2sd to free up some more system space but because its sh1t it just completely ballsed up my entire install. I installed an RU and this left me rooted with s-off and it was plain sailing from there to reinstall recovery and flash my custom rom again. I'm using a different sd card now (for testing purposes) but I'm still getting the pb99 errors. As you say, it will eventually allow me into recovery and I can continue what I'm doing but it takes ages and I've never had this issue before.

There's your main problem, do not use MiniTool Partition Wizard. More often than not it creates improperly aligned partitions. Link2SD won't have helped either, it's a messy method and you don't need it with 4.2.2 ROMs, follow the instructions to activate A2SD via terminal commands.
I would backup the FAT32 partition of your sd card, and reformat and repartition the whole thing using gparted. Use this video guide to help
Basically you want to remove all partitions and create one FAT32 partition, and max 2GB ext4 partition. You might as well keep it ext4 over ext3, it should be marginally faster.
Then full wipe and reflash ROM, don't use link2SD.
You should also look to s-off, search for guides, much more powerful, and useful if things go wrong.
hey I'm currently using a fat32 second partition for my link2sd setup but I need an ext2/3/4 system to link the internal data (for google translate offline language packages) to my sd card as well.
I read that ext4 is not supported but ext3 is.
Thus, my actual question: can I reformat my fat32 partition to ext3 and keeping all the links and files so I don't have to reinstall/move all the applications currently linked?
Create 2nd partition as ext2...
Then, Recreate mount script and select ext4....
Reboot....
It will work....
It moves data also....
Enjoy.....
Wouldn't the data that is currently on the second partition be lost in that process?
Yes it would be. Formating deletes all data on the partition.
Can I just make a backup of the contents of the partition (copying all files) and put them back after the reformat?
Will link2sd still recognize these folders, will there be problems about permissions, ...
Thanks for the help because I basically messed up choosing fat32 in the first place :/
Theoretically it should work. Never tried that, so I cannot be sure.
Ok thanks.
I'll try it soon and post back the results
Link2SD to Link2SD Plus-FAT32 to ext2,ext3,ext4 or f2fs

Hi, KoenGo I saw ur post, n I too was going to post d same question.
Actually I m switching from Link2SD to Link2SD Plus, n av to change d second partition from FAT32 to ext2, ext3, ext4 or f2fs.
I av posted d same question 2day in PHANDROID-Android Forum, so if I get an answer from them I'll let u no, n if b4 that u find out something, u let me no.
Goodluck n Thanx.
Just formatted the second partition to ext2 with Gparted and moved back the backup files from the partition. Selected ext4 when link2sd asked for the file system (I know it's weird but it worked).
Apps were temporarily uninstalled, so shortcuts on home are gone, but other than that all is working fine now.
Now I just need to get the plus version to link the internal data.
