Stock SD Card Class?

I've got and old version of CM, and before I upgrade to 2.25, I want to partition the SD Card that came with the phone to allow Apps2SD. The manuals suggest that you need anything above a Class 2 SD Card, but I can't find any information on Google as to what the stock MyTouch SD card class is. There's a big '6' on the card itself, but I'm hesitant to think that it came with a Class 6, considering that a class 6 is top of the line.
Thanks.

the stock sd card that comes with the mytouch is a sandisk 4gb class 2.

Dang! No Apps2SD then.
Thanks.

You can still do apps2sd with a class 2. But on a mytouch it is unnecessary because you have nearly 300mb for apps. the g1 only had about 80 and that was with the hard spl giving you extra space.
If your memory card has a 6 on it, then it might be a class 6. anyway that you can post a picture to confirm?

Hmmm, maybe I misunderstood the purpose of Apps2SD then. I assumed it was so that if you wiped the OS of the device, you wouldn't have to go back and re-download all of them. Is it just for extra space?
I don't have something to take a picture with at the moment, but it sure gives the impression of a class 6. I'm going to skip the partitioning for now, and do it later, since it's not vital to CM 4.2.5

If you are just upgrading to a newer version of the same rom, or wiping a rom, then yes, you do keep your apps. If you flash a different rom altogether, it is recommended that you wipe your sd card, including the ext partition. so you lose the apps if you do that.
It was originally for extra space because the G1 could only hold like 30 apps and the memory would run low, or you could download some apps that are about 6mb in size, and you would fill it up even quicker, and with the cache being stored on the phone, bye bye phone memory in a flash.
The mytouch fixed that by having all that much needed extra memory for exactly that purpose. If you are worried about having to redownload all your apps again, get backup for root users. It will backup your apps, and if you wipe, or jump from rom to rom, you can get them all back with just a couple of key presses.

Ah, okay then. Thanks for the help.

Guide to upgrade to larger micro SD card when using apps2sd

I thought this might be useful to anyone else in my situation. I had apps2sd installed on the stock 4GB card but purchased a larger class 6 card and wanted to seamlessly switch over without reinstalling all my apps and have my application data work correctly etc. I couldn't find a straightforward guide online so I gave it my best educated shot and it worked for me. If you got apps2sd working then you should be familiar with the partitioning etc.
I got it to work upgrading using the following steps:
1. Nandroid +ext backup!
2. Copied all files/folders from old (stock) card onto folder in computer using a card reader (apps2sd and linux swap partitions aren't visible but are included in the nandroid ext backup) (Put aside old/stock card with all original data and partitions just in case the rest doesn't work)
3. Inserted new card into phone and booted into 1.6.2 recovery (go Carebear!)
4. Partioned new card. (I actually changed the partition size from previous setup so it shouldn't matter as it worked fine for me. Made 32MB linux swap and 512MB ext2 and the remainder FAT32)
5. Upgraded ext2 partition to ext3. Shut down.
6. Removed new card from phone, insert into card reader and copy all files from folder backup of old card onto the FAT32 partition of the new card.
7. Insert new card back into phone. Boot to recovery again and do a Nandroid restore of your +ext backup and VOILA!! It boot looped once but after second boot it has been running flawlessly with all apps installed on ext3 partition and all original data in place etc.
Hope this helps anyone confused, as I sure was. It really was much simpler than I thought it would be.

Thanks for the procedure, that will be very useful!
I'll also take this chance to ask you how were apps2sd performing with the stock 4Gb SD? this is the one thing that's keeping me from going the apps2sd way, not knowing if the stock card is too slow for it to work correctly.

Honestly, I didn't notice ANY difference in performance once I got it set up correctly. I have a class 6 card now but really, they seemed to run perfect on the stock class 2.

The real difference between a class2 and a class6 has to do with the swap, not so much a2sd, although the apps may load a little faster(nominal difference)... it really is all about the swap, and being able to write and read it faster.
On a G1, with 96MBs of swap, and most of a Hero ROMs RAM being on the swap partition, it was a huge difference, very noticeable, with the N1, very little will ever end up on the swap, and mostly is there to make it so that you can open a few more apps.

What do you recommend for size with the swap partition on an N1? I just went with the default 32MBs. Will I see any increase in performance by increasing that?

It is all about preference... with the N1 there really is little to no need for a swap. If you use it, yes the developer recommended 32 is probably best.
But this phone has so much RAM, that swap isn't really needed at all. The whole idea behind the swap partitions was so we could boot a larger ROM than the stock phone could handle, ie a Hero ROM on a G1.
None the less, there are some small benefits gained with swap used with one of the Desire ROMs... for me, I don't use enough different apps to really see those benefits, but others that use tons of apps will see the added RAM.

Thanks! I have a lot of apps installed but I'm rarely using a lot of them simultaneously so I guess no need to worry about it. I mean, this thing frickin' FLIES as I have it set up now!!

[Q] Bad SD Card?

I've been getting the SD card was unexpectedly removed error for my 8GB card. Can repeat this issue by moving pocket god (or several smaller apps) to the SD card. I can how ever copy 8GB worth of data from a PC onto it, so is this issue with android/my phone or is the SD card just acting weird like this? A 2GB I got with it works just fine, just it isn't large enough to suit my needs.
Things I've tried - erasing card within android, formating to fat32 within windows as well as defragging, and threatening it with magnets.
Phone is HTC Legend running "Gingerbread + CyanogenMod". Download the ROM from derhofbauer.at/android/
Later;
Now when I copy it through the phone usb it now dismounts, but I can copy it fine through an adapter I'm using. Seems this is phone related. Will try using my default firmware tomorrow when I get time. Any suggestions here are welcome and encouraged... Really like the way this ROM looks as well as functions

It may well be the ROM, I saw some stuff on gerrit about fixing it. Check with BlaY0's ROM (or similar) or CM 6.1, see what happens

Is there a way I could go about backing up my exact settings, contacts, apps etc. into my own custom rom so if it isn't the ROM I use I could quickly go back? Still a complete idiot with android so haven't figured out theming yet and like my current ROMs look
edit;
If it was my ROM wouldn't my 2 GB one be acting up as well? Cause it's working perfectly fine, I plan on trying to return the SD card tomorrow but got a feeling they won't accept it back...

It might not, 2GB card is most probably SD aka SD 1.x, 8GB is SDHC aka SD 2.0...It might be related...
To backup your settings and ROM I would recommend backing it all up with nandroid (CWM, FakeFlash) or if you want to, you can ue some apps like Titanium Backup, My backup etc...but backing-up/restoring settings/home screens might not work across ROMs, especially going from Stock-like to CM...Contact are saved via your Google account any synchronized afterwards anyway, so don't worry there ;-)

[Q] better way than booting from sd?

ok guys, noob here ive got my nook running cm7 off the sd card itself but its super laggy, and i cant stand it is there a better way to root it so i dont have to use the sd card and which method has the best success?

If you are not using a sandisk sdcard, you should give a try:
http://forum.xda-developers.com/showthread.php?t=1005633
Good luck!

any others???
this pny class 4 8 gig card is the only one i have im down to re root the whole thing if that is what it takes... i just wanna have something that works half way decent

I've had bad luck with the PNY cards.. Sandisk made it run really well.. amazing difference..

ok cool ill find one somewhere

But the question now is, do you want to upset your stock OS or not?
Or is there a new way to install CM7 on your eMMC without interupting the stock OS?
My NC is still under warranty so I don't want to take the stock OS off yet, although I am very tempted to trade places, putting my stock OS on the SD card and CM7 (as I use it so much more) on the eMMC.
If you don't want to touch the stock OS yet, the sandisk is optimal for these units.

In fact, if you will dig around in posts about SD cards and CM on AD cards, you will find opinions and actual performance tests showing that CM from an SD card can be as fast as CM from eMMC... if you use the correct card.. which is a Sandisk class 2 or 4 of any size.. 2gb and up.
Don't ask me to point you to the posts.. I can't. I only remember reading these things when I was doing similar research.
For $10-20 you can give it a try and do something else if you are not happy.
.. or if you are sure you don't need easy access to stock, go for an eMMC install..
Neither solution is irreversible..

There's nothing the stock Nook can do that Android can't and there's probably a list somewhere of the things Android can do that the stock NC ROM can't but it probably wouldn't fit in this post. Search for 8+1, you can always fall back to "so clean the video wants to play".

Thats not an issue as you can always restore to stock if there is a problem. That is Part of the greatness of SD boot priority. You can restore no matter how screwed up your internal memory is.

The warranty is not really an issue as I found when I had to have mine replaced. You just restore it so stock. When you create your install image SD card save it in case you have to return your Nook. If that happens, just place the stock ROM .zip on the card and boot from it and wipe everything like you were installing CM7 all over again but instead just flash the stock ROM. It can be found here: http://www.multiupload.com/BW8FIEJ2GH (With thanks to Taosaur.)

ok so now ive got the sandisk card in it it benchmarked 1888 i was way supprised but now it doesnt show up on my computer when i connect the nook via usb i want to still put books on it but it wont boot if i put the books directly on the sd card itself

I didn't follow all posts from the beginning so I just make assumption that you're booting CM7 off the Sandisk uSD.
No personal stuff should be placed in the boot partition. Place them in the left-over (/media) storage.

Just install it on the internal memory there are many great Tutorials on it.

i tried to get to the internal memory but it doesnt recognize it could i partition it and use the second partition for books?

I can tell you that I have been running CM7 with nightlies off the uSD card since I got it (3/11). Using an 8gb Sandisk is indistinguishable in speed from the stock system, but SUBSTANTIALLY more useful. Since my NC is still under warranty, all I have to do to "restore" it to stock is take out the uSD card. I love it, and it doesn't take you into the "restore to stock" mess that, while it works fine, is still pretty stressful.
Try a good Sandisk uSD; you probably won't need or want to flash your internal memory.

Using Apps on SD with 2 different ROMS

Been searching for a while but am confused. Never needed to use my external SD on vibrant until recently. Now I have a question. I have two different ROM versions on my phone and I use ROM manager to keep them backed up and I use restore to go from one to the other.
The question is, now that I had to move some apps to my sd card (using Apps2SD), what happens when I switch ROMS by using restore?
Do I need two different partitions on the SD card, one for each ROM? If so how do I do this, and how do I know which partition each ROM will use?
I have read many warnings about partitioning using ROM Manager so I am kind of leary of using it.
Can anyone explain this to me? Never thought about it before because the Vibrant has so much memory available.
Thanks.

Any ideas?
I'm sure lots of people have done this before, just not me.
Can anyone explain this to me please?
Thanks in advance.

I have NEVER heard good things about partitioning your SD card with ROM mgr. NOt sure why you would anyways. The internal is already partitioned anyway. That is why we have a phone marketed with 16gb internal but when you pull settings>sdcard it shows only 14gb. Where are the other 2gb at? There are already partitioned to put your apps there. Use Root Explored and go to /Data, /datadata/, /dalvik-cache and you'll notice that they are all the same size-nearly 2 gb. Viola!!!
As far as restoring. I don't use native App2sd but I know how it works. W/o getting too technical, it puts part of the app's apk (executable functions and data) in a folder called .androidsecure on your sdcard (if you want to view this folder, you have to plug into PC and make sure Hidden Files are viewable). Now to your question. Whenever I have backed up, I always see at the end when it is cycling through your partitons (/system, /data,...) it says something like "backing up .androidsecure"-file not found*b/c I don't use it is why it isn't found. So you can back that up if there is something in it, flash new ROM redownload your apps and move to App2sd, back up and when you restore it should restore the .androidsecure partition.
Sorry for the long response but you asked two questions there. Now for my question. How many friggin apps do you have to fill up everything and bleed over into the app2sd part too? Does your phone lag? How is battery life?

Using App 2 SD Pro
Perhaps I didn't give enough info, but I am using an app, called App 2 SD Pro, to move apps back and forth to and from SD card.
It shows Moveable = 98, on SD card = 17, and phone only = 98, so I suppose it have 213 if it is correct.
Thanks for the info about restoring. I will have to study your answer in more detail before I can give any more answers, or ask any further questions.

re download my apps
Part of your answer above was redownload my apps.
Don't want to do that. If I move some of my apps to the sd card using the app "App 2 SD Pro" and then do a backup using ROM manager, then restore another ROM using ROM Manager, which also has apps on the sd card, what happens to them?
I have done this and it seemed to me that some of the apps which had been moved to the sd card did not show up on the restored ROM.
This is why I asked about partitioning, maybe using one section of the external sd card for one ROM and one section for the other.
