So here is my situation. I had the EVO 4g and just got the LTE (loving it BTW. Haven't rooted yet. Gonna wait a little bit). I'm sitting here at work plugged in as USB cleaning up my SD by organizing videos, pics, files, etc... Then, when I went back to the phone, there will still things there that I had deleted or moved. I was totally perplexed. Then it hit me that I partitioned my SD on my previous EVO. When the phone is plugged in as USB I am unable to locate the extension. How do I access the extension that was added?
Any help understanding this is appreciated. Thanks
Ok so I downloaded ES File manager and now I can see the ext_sd. But now it seems when I had the phone plugged in as a USB I was actually in the extension the whole time. All the things I did to organize my pics and files were in the extension. Also it seems that the phone is storing new pics and downloads on the extension. Can I undo an extension? I just want to have control of where things are stored and be able to organize them. This partition in really messing with my head...lol. This is a bit confusing for me so any help is appreciated.
Thanks
So are you saying you can't see the partition you made on the SD-card? Cuz if you are, that partition is in either ext-2,3 or 4 which Windows cannot see. So you have to use Linux to see ext partitions and move stuff, whatever with it.

That is correct. Can I undo a partition?
So when I take a picture it stores it on the ext. The gallery displays images and videos that are on both the ext and that are not on the ext.
When I'm in ES File Explorer I can see ext_sd. I can press and hold and it gives me the option to delete. What is going to happen if I delete the partition from ES File Explorer? I do not need it now with the LTE and all the extra memory. I suppose it will just delete everything on the extension but the extension will remain?
If you still have your old evo you can use ra recovery to re partition the card. Set swap and ext to 0 mb. This should restore the entire sd card to its full fat32 size.
Edit: this will format your sd card so have a backup of data.

Is "erase storage card" the same as formatting the card?
After I erased the card I went into ES File Manager and I can still see ext_sd. There are still file names on the card it seems but they all appear to be empty.

Yea....unfortunately it is for windows. It's 16GB card.
The "erase all data" did not eliminate the ext (I can see it in ES File Explorer). The phone stores new camera pics on the ext. It looks like all of the information on the card is in the ext. So when it's plugged into my iMac I am seeing the ext only and thats where I drag it into as I have no choice

Put the sd in a card reader or connect it while the phone is in recovery and don't forget to mount the ext partition, then redo the partitions. This will wipe everything so if you want your data back you have to find it some other way.

In recovery there is a option called mounts and storage (or something similar) make sure you mount the fat and ext partition. If you don't see your data then you can try some sort of data recovery program.

Fix it with card reader but my data wasn't there
Said 3,15GB total (rest is ext3)
2,41GB free and 758MB used space...that means that my data is on sd card but I can't see it?!? Because I see just 4 folders which are empty (0 bytes)...what's with the other 758MB? Where they are?
I recoverd almost everything with PowerDataRecovery tool, but don't want to put it back to SD 'cause of this 758MB of used space...
Anyone have some idea what can I do? Before make another format...
ES file explorer doesn't work and SuperBox File Manager doesn't work...can't believe it!
Do I need to format SD card and loose my (hidden) data?

I fixed problem with unmounted sd with card reader/right click on sd/properties/fix...
I've had this card in my rooted Droid 1 as well as a Archos 101 tablet and in both of those instances I've moved apps to SD as the internal storage on those is too small. Now that I'm going to be using this 16gb card exclusively on my rooted Evo 4G I have no reason to have space taken up by apps that won't be used or are on internal storage on this device. I want to find the folder and delete the contents to free up some space. I see one called /Android/data and another that is just /data both on the SD card. Either of these what I'm looking for? The former appears to have some older apps that I'm not using any longer but it also seems to have a couple that I'm currently using but haven't knowingly moved to SD card.
Thanks!
With a system level file manager like Root Explorer, navigate to the /data/app folder and the /system/app folder.

I'm not talking about the current location of all my current installed apps. I'm talking about the location of apps when we move them to the sd card. I wish to locate those folders from my previous devices and delete them as all of my current apps on this device are on the device and not moved to the SD card so anything on my SD card in the way of apps should be from previous devices.

android 2.2 uses the .android_secure folder on your sdcard. for the native apps2sd. if you are using some other kind they use a ext2 or ext3 partition on your sdcard. you will need gparted or linux to see this type.

You could do that, but first, were you using some other type of apps2sd? Not the android native one that started in version 2.2? Dark tremor or any other flashable or aftermarket apps2sd that uses a ext partition on your sdcard?

I would have used a combination of individually clicking 'Move to SD card' within some of the apps as well as SDMove (which I believe actually uses the same location as moving them within the apps themselves). I don't think I used anything else but I had that phone for 18mos so it's hard for me to remember for sure. On my current Evo I haven't moved any apps to the SD Card because there's much more room on the phone than my Droid 1 and I'm actually running into problems w/capacity on my external 16gb SD card. Hence the reason I'm trying to free up some more space from objects that are unnecessary.
Ok, so what you can do is just backup your music and pictures and whatever else that you know what it is and format the card. Then move everything back afterwards.

I was hoping to avoid a format but sounds like I may not have much of a choice. I need to back up pictures, Mp3's, Titanium backup, Clockwordmod and a couple other folders and reformat. I was hoping it would be easier to track down all the loose ends though.

If you moved them just using the Move to SD card built into Froyo (including apps like SDMove that just help you do that), you shouldn't need to reformat. That's only if you set up an ext3 partition.
Mount the card and view it from the computer (or use a card reader) and delete .android_secure. The real folder is hidden when the card is mounted on the phone.
So, this device handles storage slightly differently than my HTC EVO 4G did. That, which pretty much needed an SD card for storage, mounted it in /mnt/sdcard/. This phone however, mounts the external SD card in /mnt/sdcard/external_sd/. I am guessing this is because this guy has 16GB internal storage already, and changes are if you were to dissect the phone, you'd probably find an SD card in there too.
I am thinking I'll just move my card contents over to internal storage. Programs that backup/restore data to /mnt/sdcard/ don't realize that this path isn't actually external storage.
I am wondering how this will affect those of us that frequently reflash. Does that partition get wiped when the ROM is wiped? Or is it really just another SD card internally that isn't touched by the system kernel or ROM except for storing user data?
I also have another Q, that's not online with the OP exactly but related to the topic. I'm coming from an e4g to the et4g and plan on using my sdcard from the e4g in the et4g (at least until I buy a 32gb card). I notice that there are many system files on the sdcard from the e4g, are these gonna be an issue with the et4g?
also, I was thinking to make a backup of the card as is to a hard drive, then delete all the files and reformat the card (fresh start), then add back only those I feel are necessary (backup apks, titanium backup files, pics & vids)....is this feasible?
lastly, are there any "don't touch" files on the scard that I should be aware of.

So, what is your question? You should be able to move the card, but like I stated, the paths seem to be different. It may be the same for you since both devices are Samsung, but maybe not.

There shouldn't be anything you shouldn't touch. As far as I know, I think a program like Titanium Backup will archive everything.
What I would do is use Titanium Backup to backup old phone and restore to new phone. Then start the programs you use with personalized data at least once. If you end up with paths on both the phone storage and external storage, move the external over to the phone, replacing/combining.
I ended up doing this and found that my external SD card is now empty.. Starting clean!
It's pretty amazing how far 16GB built into a phone can go. I don't use my phone for movie watching or music often, so we'll see. Maybe I will.
I just notced on the e4g that there are 2 paths that both seem to lead to the same. destination file.
one is: /mnt/sdcard
the other is: /sdcard
the content is exactly the same. not sure if that info helps you any.

Once you move the SD Card from your EVO 4G to the Epic 4G Touch, attach a USB cable to your PC. In the notification area on the phone, you have to touch the USB Connected status and then touch the button that says "Connect USB storage".
This will mount TWO removable disks. One will be the size of your SD Card. The other will come in at around 11.5GB. The 11.5GB is the internal storage.
Just use Windows to move everything over. You may want to back up both before you make changes just in case.
If the hardware doesn't mount in Windows, you may need to install the drivers first. They are installed with Samsung Kies, which is on their site.
If you need more info, let me know.

If you go into tibu there is an option store back ups to orignal location needs to be selected so when you restore if its on the sd it will restore to sd. Just go into tibu hit menu then preference. About half way down you will find the option.

There is an app called sd maid which I use to clean up sd with corpsefinder option. Just be careful with the app it can delete things you need.

Your card may not be completely hosed. You may be able to save it by reformatting it.
Thing is, while TouchWiz carries the ability to handle exFAT-formatted cards (the standard for SDXC cards), CWM ordinarily not (this is due to patent issues; blame Microsoft). Unofficial builds that tack the ability on risk legal trouble so I won't discuss this.
There ARE Windows programs that can reformat the card (like Easus Partition Manager). IINM, there are similar tools already available for LInux and Mac users. While FAT32 prevents you from carrying big files around, it should be visible to any 3rd-party recovery system.
One thing I should chime in. Since the GS4 uses Android 4.2 and up, the nandroid backups you make are hidden away somewhere in your storage. They won't be visible ordinarily because of filesystem protections. As noted earlier, the recovery programs can see their own backups and allow you to manage them. In addition, if you're using CWM, I think ROM Manager (from the same developers) can let you browse the backups from within Android.
PS. I've personally found the best success with SanDisk SD cards. I've had trouble with PNY ones, but I haven't used Sony ones much (usually due to price).
