[MOD] Swap Internal SD and External SD

zimphishmonger · May 23, 2011

Hey everyone,

Found this mod for the Galaxy S (Or SGSII, not sure what the i9003 is), which switches the Internal and External SD cards, according to the Android OS. Personally, I have a lot more space of my external SD and would like games and such to store their data there, instead of on my smaller internal SD. Some apps like Titanium backup can change their data locations, but Games such as Gameloft games and the like cant have their game data moved to the External SD card atm.

This looks like a great alternative to this issue, could this hack be adapted to the G2x?

Although I could see how you would think this would be in development, this post should actually go in Q&A.

That being said, this would be a very useful modification.

Edit: My apologies. Apparently you posted in precisely the right forum. My apprehension arose from the fact that so many people say 'BUT WHAT ABOUT THIS MODDD??!?!' and it just clutters things up so my immediate reaction was to motion to have it moved. Good deal bringing it to Krylon and Tweezit's attention

I couldnt decide between Q&A and Development for this topic, as it involves porting or adapting a hack for another phone to the G2x.

MODS: Please move this to Q&A, if necessary.

EDIT: Apparently not, this seems to be a development topic now

Here is a file Be warned I have not tested this. If it messes your phone up I am not held responsible. **Personally I would let another dev look at this to be on the safe side as I am not 100% sure on this.**

You will have to extract it and use root explorer to push to /system/etc/

Oh I needed to clarify this was on 2.2.2 so it may differ on 2.3.

Since we have a little interest, we'll leave it for a day or so and see if anything comes of it.
I've PM'd krylon to take a look at Tweezit's vold. (sounds like a nasty STD).

Smart move as I spent all of 2 minutes looking through the file as I am in a rush to leave

Later guys ^^

I'm looking at this now. Your biggest issue is you are going to have to have 3 different versions... well... in reality 2 different versions. CM based and Non-CM Based.
And if someone flashes the wrong one...they are hosed and will have to restore from a backup

krylon360 · May 24, 2011

ok, after reviewing Tweezits vold, Bionix vold, and CM7 vold, tweezit's would break mounting.
The reason being, with the introduction of Tegra, the vold changed for it.

I'll have to do some testing, but making the internal to external switch should be fairly easy.

Is there a way to have setting like a switch to interchange between the two

We need to decide on a standard. Unfortunately some people don't have SD cards but I'm sure most people would that visit here.

I'm for the switch cause i hate crap installing to my internal drive. Cm already made the switch.

I'm with you. Maybe we should put together a poll or something...

Multiple versions just confuse the new guys. Would be nice if there was some priority... Like use SD as first choice then fall back on internal if SD is not present.

That still complicates things as people wont know what's going on.

****best idea****
If CWM flips it by default then you can just streamline everything and make a public service announcement on the CWM download page that they will be flipped and an SD is required for flashing. Makes sense to use a SD for flashing anyway.

Even a 2gb is plenty for some Roms and app storage. Save the internal for personal music and other media. I hope no one rocks less then that these days.

Plus if you use internal storage I can see certain scenarios popping up where they are boot looping and lost their access into the internal files. I can't mount using 3.1.0.1 external. If it werent for my SD I'd be stuck hardcore.

I'm kind of with you on this one. I use all of my roms and such for the external SD card and everything else for internal.

Good point however 5gb of internal space is not enough for me since I have 10gbs of music onmy sd card. I wish there was a way to have a switch function that will enable you to choose which sd crd to download to

I've attached the CWM flashable .zip of the mod I've been running for awhile that will swap your SDcards. Never been able to get it to mount the external card as a folder inside /sdcard/. Didn't really want to release it until I did, but here ya go anyway

BTW, is it just me, or do init.d scripts not work in CM7?

This is for CyanogenMod only!

I don't have the volds from other builds on hand to mod them....

zimphishmonger · May 24, 2011

WOW! I come back from long day of work and find all this discussion.....awesome!! Thanks for chiming in guys. I def understand there will have to be at least 2 versions cause of CM, but as its a file, couldnt a simple app\script be created to swap it back and forth, after detecting CM or not? It may be a lil beyond my scripting knowledge, for the detection portion at least.

I see a ton of useful reasons for this switch, as the 5GB isnt the 13ishGB that the Galaxy S has and doesn't quite satisfy the requirements of a "primary" sdcard IMO. The 5GB would be useful as an "_InternalSD" folder bind\mount (whatever is being used), with the External SD as the main SD card. I'll list a few useful reasons why.....

Off the top of my head......
If your a serious gamer and you have a TON of games that have downloadable files put to the SD card, that 5GB will go quick (Gameloft I'm looking at you)
External SD can hold WAY more nandroid backups than Internal SD, and ROM Manager would recognize them (I acknowledge the external sd issue is not really an issue w/ the two ext4 recoveries)

I humbly disagree.... If anything it would belong in the General or Development. It is a work towards development and there is no "question" being asked. Just because it isn't a ROM, doesn't make it any less important to work on the phone.

Just my .02
