Ext partition with Evo - EVO 4G Q&A, Help & Troubleshooting

So i know on my magic i always had a Swap partition, EXT, and fat32...
Seems like when i got my Evo, the SD card only had a fat32 and no EXT.
When installing custom roms, Should i just go ahead and reformat the card with EXT or do we not need it on the Evo. From what i know of the EXT partition and working with my magic for so long, i would assume it still needs to be there but it was just odd that it wasn't there from the factory when i got my phone.
TIA

IMO, a2sd isn't necessary on this one
I have almost 60 apps installed (including the behemoth Google Earth), yes I know how ridiculous that is, and I still have over 200MB internal storage free.

The EXT2/3 and Swap partitions didn't come stock on your Magic, either.
It's up to you. Like nebenezer said, it's really not necessary on this device. The only reason I'm running a2sd is so that I don't have to mess around with reinstalling all my apps when testing out new ROMs. That's really the only reason at this point why a2sd would be an advantage. In fact, unless you're using a class 6 SD card (which the provided card is not), it actually probably slows down the phone a bit when launching applications.

Ahhh.. So EXT is pretty much only for A2SD? Thought there was some other info on there...
And i know what swap is..
Cool. THX

pretty much, you can move dalvik to sd and I think data/data too but like CentroniX said unless you have a c6 or greater card your better off skipping a2sd on this phone.
Not having to reinstall your apps is convenient but when I flash a new rom I wipe EVERYTHING anyways. I always like to start with a clean flash so if there are any problems I know its not one of my apps. Plus titanium backup makes it very easy to restore everything.

I switched to Apps2SD. My internal storage is still only 200MB. Why? How do I lower?

Am I supposed to go back and erase all of my apps from internal storage after they are moved to the SD card? If so, how?
I just don't understand why I only have 200MB out of 1GB available. All of my apps are on the SD card now.
What do I need to delete out of the internal memory?
Any help is MUCHO appreciated.

You don't actually have 1GB of usable storage space by default. It's split into partitions, and the user storage is only ~512MB or less (I can't remember how I saw what the internal storage was split up as...)
"ONLY 200MB"
How much do you need?
I get your point. You get the point of my questions though, right?
If you have a fast SD card, you can move the dalvik cache to the SD card and free up another 60 megs or so.
You'll never see most of that gigabyte on your phone. Ever. I think the maximum you're allowed for apps on the internal flash storage is 350 megabytes. Even with Apps2SD, I think the dalvik cache for all of your apps is still stored on the internal memory, which would occupy some space.
I don't know what the heck I'm doing is the problem. Once I figure it out, I'll post some stats for new guys like me.
I've formatted my card correctly. Now I'm just trying to figure out if I'm supposed to wipe my system and reinstall in order for the apps to get "moved over" or not. I'm curious as to whether My Backup Pro or Titanium will "restore" the apps to the SD card now that I'm formatted correctly.
I believe the "moving" is not really moving it happens on install. So yes starting fresh is probably the best way to go.
There is only like 350mb or so of user installable space. Depending on rom it could go up a little but its close.
Also remember, not every single portion of the app gets installed on the SD. Some files still need to be stored on nand, just less. Much less depending on the app.
Just make sure you have a decently fast sd card if you want to move dalvik there. class 6 or better imo. It will work with a slower card but it could slow things down.
Froyo requires ext4 partition btw. Not sure what rom your using.
^^ Thanks for the info. I'm using Fresh 1.0.1, which is good because I don't even know how to make Ext4. I'm using Amon RA to partition and the only upgrade option was from 2 to 3. I didn't see anything about 4.
I'll wipe clean and see what happens.
Oh, one more thing that your post made me think of. The whole reason that I'm doing this is so that I don't have to re-install apps every time I wipe and install a new ROM. I figured that the new ROMs would just find my apps on my SD card.
If this isn't the case then it is not worth it to me. Meaning, if I still have to re-install all apps each time I wipe the device there is no benefit to me.
So: is that the case? Do new ROMs just "find" the apps on the SD card?

[READ]Sd card partition

Ok if I do a sd card partition what are the benefits from doing this action?
What will happen?
What are the pros and cons from this?
If I do a sd card partition will it delete everything from my sd card?
Will it ruin anything?
I NEED HELP.

Copy contents to your pc. Format sdcard thru phone. Flash amon recovery. Boot into recovery, partition thru recovery on your phone.
App2sd allday. No cons

Benefits is extra space for programs.
Like the poster above me said, copy everything off your phone on to your PC and use Amon Ra's Recovery to do it all for you automatically.
It will not ruin your phone or sd card.
You'll be fine.
It said on rom manager that it cold do it. What sizes should I have? Ext size 125? 256? 512? And swap size? 32 64 or 128?
Somebody help?
Sent From My HTC EVO
it's really your choice. If you want more space for your apps, make the ext partition bigger.
the swap partition (i think) really shouldn't be as important for a evo (as it's got plenty of ram and processing power), but you might as well make a 128 swap.
Well I mean can't you already out apps2sd already Without partitioning?
But what happens to the other 256 half of my memory where will it go?
Haha sorry.
What do you use tho?
Sent From My HTC EVO
meh, I'm not too familiar with 2.2's apps2sd methodology...
my SD card is still formatted from an old MyTouch 3G Slide, with like a 256 MB ext and 64 MB swap.
neither partitions will actually be "visible" when you mount the sd card, unless you view it in linux.
the space that you use for the ext and swap will be taken away from your total GB.
so if you have a 8GB card, and partition away (theoretically) 512, only 7.5 GB will be accessible to you.
I say go for it, if you think it'd be nice to put apps on to an extra partition for more space and not having to worry about whether that app is still usable and functional when you mount your SD card.
And the swap partition... I know how useful it was with older phones (like the G1) and how essential it is with almost every linux distribution, but I really can't confirm or deny any benefits it would have on an Evo.
it certainly wouldn't hurt it (i think 0-0) but I can't say it'd help too much either.
I think you could at least give it a shot. If it doesn't do anything, then you haven't really lost much. If it helps a lot, then you've gained something. If something goes wrong, it's rather easy to get back to normal.
Hope that helps.

Linux/ext3 SD card partition issues.

Hey all I am hoping someone has a little experience with Linux and can give me a helping hand. Today I bought a new Samsung 8gb class 6 Micro SD card and I want to transfer the data from my ext3 partition on my class 4 to my class 6.
I have nothing on the class 6, I have installed Linux to a USB stick and I have formatted the SD drive with a 512mb 0 swap ext3 partition however, it won't give me any access to the partition it's self. I was thinking I could just use Ubuntu to go in, partition (yes I know I can use ROM Manager ) take the card out, and put in the old one copy and paste the ext3 partition to the desktop and just drag and drop back. But it doesn't seem to be the case.
I am gettin some write/read errors or something of the sort, it's driving me up the wall. I could spend all night trying to read through Linux code to try to work out how to do it, so I thought I'd see if someone knew off the top of their head or knew of a better/easier way for me to swap data from one partition to another, I can't seem to find a useful thread on it searching the forums either.
Does anyone have any ideas, or an easier solution?
I'm also having a problem with this. Any suggestions?
you could do a nandroid backup with your old card, partition your new sd card, copy the backup to the fat partiton on your new card, then use the advanced restore option to restore the ext to the new sd card (if that makes sence) lol

I might give that a go, I never did find an answer to my post.
I've given the shiny new fast SD card to the girlfriend now as well as I really didn't want to hard reset the phone and start over, own goal. I might see if I can pinch it back and put it in mine, it's not like she needs a class 6 for a Wildfire. ^_^

I quite like the little phone, it shouldn't come with Sense though, it kills it. I've put LauncherPro on it and it flys for what she uses it for, facebook, e-mails, Twitter and all that. Shame the 768Mhz overclock isn't stable enough to run 24/7.

Bought a new SD card, what do I have to move across?

I just upgraded from an 8GB Class 4 MicroSD card to a Memorette 32GB Class 10 card (got it for like £25 on ebay ). I want to move everything on my SD across so I don't have to re-install etc...
I'm not so much worried about my apps, but what other data is on my SD? Is there stuff to do with my root, ROM or anything on there? I see a lot of folders on my current SD which seem to be related to the OS (not things I have created).
Is everything held on the phone, or do I need to clone the card for it to work straight away?
A lot of apps and games use memory card to hold stuff in seemingly random places, just move the lot to be safe.
Do you have an ext partition on your sdcard? If so perform a nandroid backup then copy the entire memory card over then nand restore and your done.
If you want to start again from fresh you will lose any apps saved on sdcard and some data from some apps, probably nothing important like cache from maps. It wont affect your system or root or anything though.
I'm actually not sure what I have. I literally have rooted it, installed Oxygen, installed the custom HBOOT and that is it. I haven't touched partitioning or format type.
What is the default?

If you haven't touched partition or anything your card is default!!
I would copy everything onto PC (backup is always recommended) and then copy onto your new card.... should just work from what you have said ?!

Ah, OK, if it's that easy then... awesome
I didn't know if Oxygen formatted it some special way. Good to know. Is a Class 10 going to make any difference at all. I was going to buy a normal 32gb card, but this class 10 one about £5-£10 cheaper than big brand Class4/6 ones.
Trader has good feedback, I just hope it's a good card...
Balls, I have looked around and it seems these 32GB Memorette cards are hacked and will corrupt data passed 2GB... cancel time.

DTA2SD & Zep's V6/3G Scripts

Coming from the OG EVO 4G which had only 1GB internal storage, running apps off of the SD card was essential. We had a great tool called Dark Tremor's App2SD (DTA2SD) Basically this let us store all apps on the SD card (even widgets) on the EXT3 or EXT4 partition of our SD card.
Now I know this phone has a lot of internal strorage but I was wondering if this tool could be used in our phones as well?
Also, for those not familiar with Zep's V6 Supercharger script and 3G Speed boost scripts, they were essential tools for the EVO too. Was wondering if running these scripts would have any real benefit for our phones? I personally and too afraid to jack up my phone to try it (too lazy to nadroid and nandroid back if it doesn't work
Didnt you ask this already, about 23 days ago to be exact?

heres one from the other day, not you though

Ok fine, you got me. I forgot I made that thread. But neither of those discuss DTA2SD. I am having problems with savings apps to my sd card on this phone. Some times the SD scan doesn't pick up all the apps and I have to reboot for apps saved to SD card to show up. Also, i have experienced on a number of occasions that apps saved to the SD card just disappear and have to be reinstalled.
So lets drop the V6 Supercharger talk and talk about DTA2SD. I haven't seen it talked about in these parts.
I gotta ask... on the EVO I understand since it has about 400MB (if you were using AOSP) or 280 MB for sense based ROMs... but for this device you have 1.8GB... do you really need A2SD even though internal memory can load data faster than the SD card and you have plenty of space on the internal memory?
Don't get me wrong. I am really trying to understand if there is any benefit for this on this phone since it has so much space available. I'd understand if it was considered for the future but I see really unlikely filling out 1.8GB with apps...
