I would like to start over and reinstall CleanROM 4.5 on my phone, and I thought it would be good to also format the SD card while I'm at it so that everything is clean. I've got a lot of junk in there from various ROMs and would just like to start fresh. What is the best way to do this?
Should I just do "Erase phone storage" from the settings menu of the ROM? Or maybe "Factory data reset"? Or should I be doing this from TWRP? What I don't want is to end up with a brick. I need to be able to transfer the CleanROM zip back over to the phone once it erases the SD card. Whats the best way to do this?
Erase phone storage does what you want. I've had bad luck with messing with phone storage in twrp. It rendered my sd card unreadable once.
Alright, that's good to know. Do you know what the difference between "erase phone storage" and "factory data reset" are? Just curious.
Erase phone storage seemed to do the trick. Thanks gunny.
Factory reset wipes the /data directory which is where user installed apps are stored. System wipe from twrp wipes /system also which is where the rom itself is stored.

Factory Reset just resets the Os like you're starting from the scratch without touching your sd card data.
Erase phone storage wipes the data from your sd card ie. Photo's, music, and anything else you've put on there.

So I'm about to install Tiamat's new ROM (I really want the init.d scripting functionality, plus it can't hurt to get up-to-date) but I can't remember if wiping my user data wipes out the /sdcard/ mount on my xoom. I've got 15gbs in there in all kinds of random stuff and I'd rather not wipe it if I don't have to.
What I THINK is that the Dalvik/Cache/User data wipe that I do before I install the ROM will do what it would on my phone - simply wipe everything that isn't on the /sdcard/ partition. Is this correct? I sure hope so.
Yes, that is correct. It won't touch your SD card.
Just to be certain...
Ok, but to be clear, I don't actually HAVE an sdcard, just the bigass bit of internal memory mounted AS /sdcard/. It won't mess with that right?

If you are asking about the user data wipe you will have to do I order to flash thetiamat rom,
ummm yes, it will wipe that (internal storage) but not wipe your external/removable sdcard.
Damn. Ok, well, I'll just back all of that up to the computer then. It'll take a while.
You need an sdcard to install the rom though.

Nope
Ok, so, like I thought, the "wipe data/factory reset" option in ClockWorkMod Recovery does NOT format the /sdcard/ partition, even though it is actually physically located on the internal storage.
Because of this I was also able to use the internal storage to store the tiamat*.zip rom file and flash from the internal storage mapped to /sdcard/. I'm now going to attempt to restore all of my settings and apps via Titanium Backup.
Thanks anyway guys. You did inspire me to do a full backup of my /sdcard/ partition onto my computer at least.
Sorry guys. I was way off. I was even smug about it. Well, as it turns out, you do need an SD card. Check out my post here to see what happened (a lot of dumb bad stuff): http://forum.xda-developers.com/showthread.php?t=1152121
Does selecting "Wipe Data" from Recovery delete/erase everything on the external sd card?
If so, is there any way to recover it?
Lesson learned: everything that was on that external sd card after the reboot is now gone Won't be doing that again. Should've known better
but why did it keep the movie files that i had on there and other .zip files i had downloaded? anything info would help or at least reassure me that it is suppose to happen. thanks
Do not do a factory reset with this ROM, unless you want to lose all the data on your SD card.
Nice...
I wouldn't really go blaming them right away. Did you select the factory reset option from the rom itself or from in recovery? Its never a good idea to select factory reset or upgrade from with in the rom if you are rooted. It will just mess everything up. Most sense roms you flash will have those options, just do not use them.
Always do your wiping and resets from with in recovery before flashing a new rom.
If you lost everything on your SD card and haven't done anything else to it yet, look online for some programs that will help you recovery your lost data. Sometimes they work sometimes they don't.

Most likely this happened because that ROM recognizes the sd card as an internal storage and not as an external sd card. So a factory reset would erase the internal storage. Something to remember on those phones that have 16/32GB of storage built in.
Alrighty
Noted. Thanks Will notify my phonemates
Non-critical, just an observation that I am looking for additional information on.
I purchased a 32g S3 phone from someone that already updated to CM10.2. It looked like the seller reset something (no apps, data, phone started in initial setup mode), but there was obviously a lot of trash left over on internal storage that I wanted to clear away.
After clearing everything away, and downloading several apps to help remove more, I found that the internal storage was still >50% utilized. Even digging around in the root file system, I was still at a loss to figure out where more than 12gb was being consumed.
I tried a factory reset in clockworkmod, clear cache, etc. I did not dive into formatting partitions. On restart, I still see >50% consumed space and temp folders left around in the user data /sdcard area.
Out of curiosity I tried the factory reset from the CM10 system menu. After rebooting phone, it seems like all storage was properly cleaned up with about 26gb of 32g free; significant improvement.
So, there is clearly something different between a CWM factory reset and a CM10 factory reset. For the latter, it looks like the whole user-data area was formatted and repopulated with necessary folders/files. I suspect my “lost” space was somewhere in root….
I am just curious to know what more the CM10 system factory reset is doing above what the bootloader is trying to do.
Thanks!
When you do a Factory Reset in recovery (I use TWRP so it may be phrased different in CWM) it is intentional that this option does not wipe /sdcard (internal storage). You have to choose to wipe internal storage (in TWRP it's called Formatting data") by going into that Format menu to wipe all of your data from the phone. If a factory reset wiped internal storage, then there would be an incredible amount of angry people who lost important files like pics and videos. The option is there in custom recovery, it's just buried so that when you find it, you intend to use it on purpose and not by accident.
Edit: Factory reset is literally clearing cache, dalvik cache, and the rom from your phone. If you boot it up without installing a rom then your phone won't do anything cuz it's without an OS.

And the 'system' partition in 'data'.
But all that other crap apps plunk on your internal memory remains, unless you do a 'system wipe' from TWRP or CWM. But that will delete everything on the internal memory. That's what I'd do if I were giving my device away... though I tend to just Odin/RSD/CAB back to stock (depending on the device) for best results.
Good day to all,
this is my first phone that comes with internal storage and not an external SD card so I just wanted to ask if performing a factory reset (via recovery) would erase the internal storage that holds the photos, data, among other stuff.
I did a rough search on Google and found conflicting information (some going by factory reset via Settings would remove everything, /sdcard would not be touched, and so on)
I would like to move on from using the stock ROM to trying out other flavours and based on past experiences with phones with removable SD cards, doing a factory reset will remove everything that is on internal.
Thank you for your time in reading this.

No factory reset won't touch your internal storage
