Differences between internal and external SD card?

Hallo everyone,
I just get my SGS and I notice that the memory structure is so defined:
- The internal storage memory (8Gb, but i see only 5,7) is called "SDcard"
- the phisical external Sd card is seen as a directory, called "SD" under the SDcard.
Now my questions are:
When I install big seized programs,e.g. Navigators, all the program data are by default stored in the internal memory, which is limited and fix (not expandable). I would install the navigation map on the exernal Sd.
Is this a problem of Android or just how SGS impemented it? Is it possible to make the external card be rocognised as primary SDcard?
- Why the internal memory is only 5,7Gb? ok 8Gb are theoretical but 2,3 GB less ....
Thanks
Bye

The reason it's so small is because the OS and it's apps have to go somewhere, also when Froyo is released you'll be able to install apps directly to the SD card but know that internal memory is much faster than an SD card so you may what to keep that in mind when you factor in what apps to install to SD.

Hallo Sebrina,
thanks for the answer, I supposed the 2,3 Gb were for the OS, in fact the space for application is 1,8GB, but I hoped the two memorys are separated.
So with froyo will be able really to install the app on the real Sd card, and not on the internal memory, whichist called "SDcard" by the os?
Thanks
bye

is it possible to re-partition the internal SD?

[Q] how do i know if my app is installed on storage card?

hi, how can i tell if all my apps is installed on phone's internal storage or the external storage card? I have 2 GB card, and wish to upgrade to 8GB one.
I am using Wildfire, with Android 2.1 official ROM release
thanx

If you are using a official stock rom, they will be installed to the phones memory. They will only go onto the sdcard if you are using a custom rom like wildpuzzle which has apps2sd activated.

and when you do have wildpuzzle with app2sd, you can tell they're installed on sd by looking at your phone memory , i have about 130ish mb phone memory instead of like 20 before xD. umm and they are installed auto to your sd card i believe, i think you have to check the sd-ext folder or something.

Because there are some apps that you cant simply move to the ext partition and have to be installed on internal memory i.e. gmail, youtube and updates!

yes I know that! thank you ...but I hade all that apps when installed new rom...3days internal phone memoty was 161mb and after that installed only games (apps 2 sd always aksked me to move to sd and succesfully moved them)..on phone list apps is onlu market and 3gwatchdog...on SD apps list is everything i downloaded but still dont have 161mb ...now there is 142mb and still shrinking!!! How about now???

app2sd or similar isn't moving all app-data to sd I think

Yes,but moveSD enabler does. App2SD only ask for some app's

the "problem" is, move2sd creates a sort of "link" to the data on the SD card. Thus, when you install lets say an app of 15MB, 14MB goes to the SD card, but 1MB of data (files that can't be run of the SD card + link to SD card) stays on your internal phone memory.
So when you install lets say 100 apps, that all have 1MB of essential data and 14 MB of move-to-sd-able data your internal storage shrinks by 100MB and your SD cards' storage shrinks by 1400MB.

Its shrinking because app data is still stored on internal memory.
Please post in correct section. This has nothing to do with development.

If you have a newer stock-rom (2.2.1, JPY,JS5) you can put some apps from the system memory to the internal sd (System/Application/Manage Application). The errormsg is because you run low of system memory.

sorry but im really confuse i got this
External SD
total: 7.41Gb
available: 6.33gb
Internal SD
total:5.78gb
available: 5.70gb
then there is this internal phone storage
1.63gb available
whats the difference on internal SD and the internal phone storage? is there any way we can merge the internal sd and internal phone storage. coz what i notice is when im installing apps it goes on the internal phone storage and external sd but the internal sd doesnt change even a thing

When i remember correctly is the internal sd some sort of extra memory for your phone. On the internal phone memory is the android system and space for some apps.
It is not possible to merge the mem. You can free mem when you put the apps from the internal phone mem to the internal sd.

ah so it means that when u transfer the installed apps on sd it goes on internal sd not external sd one?

Internal memory?

Im curious, the specifications of the htc desire hd say it has only 1.5 GB of memory, whats the actual internal memory? im guessing those 1.5 gb they mention is just the available space to the user

to my knowledge, the 1.5GB is a flash memory (generally referred to as internal storage), and isnt suppose to used as if its a memory card to store videos and images, which is why they supply you with a 8GB sd card and why when without the sdcard, music and photos cant happen
I would guess that the 1.5GB is meant to be used to install apps and well, just system stuff, so that the OS can load it faster.
im more than positive that the internal storage is more than 1.5GB. It could be 2GB or 4GB (if i had to choose, i'd choose 2GB). But whatever it is; X-(Android OS and System data)=1.5GB.
This is what ive have been told (if im mistaken by any change, i apologize)
