[Q] mount external_sd & sdcard as sdcard possible ?

Hi,
I've spent hours searching for a way to mount both my external sd card and the internal sd as one sdcard/ directory.
My aim is to be able to install more apps & more data, as the data often installs only in the internal sd space.
I think i've looked thoroughly throughout the forum but didn't find an answer.
I'm currently running a rooted stock rom and wonder if upgrading to a EXT4 ROM or other mean could solve this.
Does anyone know if it is possible and if so, how ?
Thanks

16gb of apps to sd isn't enough? You must be installing a buttload of programs. From what I know you'll never be able to merge the external and internal into 1 unless there's some android RAID utility which there isn't.

There would be the way of aufs. It worked on the Acer Aspire One, if anybody managed to port it to Android it would be cool.

Yes, I was thinking of aufs too.
There is also a possibility in Linux : Erase the file system of both the sd card and mount them as a VLM volume set.
But in this case, the removable SD becomes unremovable...
Thanks for the answers.

4GB Limit?

Just curious, but I would like to know what is the format of the internal memory of the Xperia Z? Right-clicking it in via windows explorer doesn't show any info regarding that. I'm asking this because I've managed to copy over (drag n' drop via windows explorer) a 4.88 GB file.
Coming from a Galaxy Note previously, I didn't think that it was possible to copy over a file > 4GB (on stock), at least not on a FAT32-formatted internal storage.
So... the question is...
what format is the internal storage? NTFS? (There's talk about how it's limited to only Windows) or exFAT?
...or perhaps I'm totally off-course and it's more of an issue regarding MTP?
Either way, I'm a happy guy with how I can actually not worry about the 4GB limit. Of course, I'm still curious... (Eh, if screenies are required for proof, I'll be more than happy to oblige)

Also coming from the Note here, but I didn't had any problem, the Note has the same File System as the XZ

I am sure it will use ext3 a linux/bsd format
Found that it is using ext4 format, so you can drop a 8Gb file there if you want

I bought a MicroSD 32GB (Class 10) but...
- Formatted it ext4 = didn't work
- Formatted it NTFS = didn't work
Unlocked and rooted phone: any way to get a format that then allows me to place file bigger than 4 GB?

Format it to ext4.
Sorry missed your last sentence. But try a different app to format it or try the phone.

I tried to format it in ext4, the phone cannot read it, and if I let the phone format it then it will be fat32...

Internal storage is ext4. This is not changeable.
External storage ext4 formatted should be readable by the phone.
You're rooted? Try to format it to ext4 using the command line/adb shell session.

This has been repeated too many times. The internal memory is ext3 or ext4 and can take any file you throw at it.
SD cards only work in FAT32 (without root and without extra drivers from the Play Store). No matter what you do, without rooting and installing some driver you cannot use anything but FAT32. SD's in EXT3/4 are not mounted, exFAT and NTFS aren't licensed.

Can you give me some more info about this? Thanks

AW: 4GB Limit?
I dont know, you could google for the information how to format a sdcard to ext4 through adb or a shell.
Another user(s?) further up said though, it wont read ext4 formatted cards. I dont know, I only use a 32GB card and have no big files. My card is fat32 formatted.

This is for the Note 2, but something similar should work for the Xperia Z.

I have rooted my phone, Is there any way to mount exFAT formatted card ?

Hi,
I do not want to start new thread so I am asking here:
Is it possible to format 16 or 32 gb hc card in exFAT by the Xperia Z (not by PC)?
If yes - is it worth doing this?

(SOLVED) SD Card working in computer, not in smartphone

Hi guys. My Micro SD 8GB card works in computer, but not in my Android devices. Any ideas?

Can you see what type of file system it has. On android only FAT32 is allowed. If it is NTFS or exFAT i think can't work on a phone. If that is your case you must backup data form card and change file-system type to FAT.

I'm not so stupid, I tried with integrated Windows tool - no luck

I know now - integrated tools and any other tools sucks, you have to use normal tools. Problem solved with SDFormatter from sdcard.org.

Problems with 32GB SD Card (SanDisk)

Hi all,
I have a 32GB SD Card (SanDisk) in my Z1. I am using Media Go to transfer my music from my PC to my SD Card on my Z1.
The problem is that only 'some' of my music is transferred across correctly and other albums/tracks play as if they have been encrypted in some sort of way. The music I am transferring is playing correctly on my PC, it is only when I transfer it that it becomes a problem.
Any help would be greatly appreciated
*Just to add, I have no problem transferring the same music across to my 8GB card. I have two brand new 32GB cards and have the same problem of only being able to transfer about half the music, the rest is unrecognisable.*

Have you tried not using media go?

I am using Media Go and straight transferring across to the SD card

Maybe you can try formatting the 32GB SD card and copying all the music onto there again to see if it helps

Re formatted (exFAT) both the 32GB cards I have and still the problem remains that some data/music is not getting transferred. I have just tested a 16GB card (same make and specs as one of the 32GB cards) from my tablet and this works and a 32GB card that didn't work in my Z1 works in my Xperia tablet Z so it seems my Z1 is having a problem with SD cards over 16GB for some reason I don't know

Try Fat32? I find it gives me the least amount of problems. I have a sandisk 64gb in my Z1 and it works just fine. Windows won't format in fat32 natively for such a large size so maybe try the format sd option in android. I believe it does fat32 automatically.

Seconded. Absolutely zero problems with my 64GB Sandisk card formatted as FAT32. Always format SD cards on your phone.

Agree, I will suggest to try format in FAT32 because all the SDHC 32GB microSD are meant to use FAT32 natively so I don't know why you formatted a 32GB card in exFAT.

Windows will not because you have to use a specified application to format 64GB SDXC natively in exFAT to FAT32.
Z1 support exFAT and will not format in FAT32.

Absolutely not true. All the High-End devices not support all the formats like exFAT so is recommended to format them via specific application on PC and then insert the card to device. BTW, the phone will format even fake cards without problems, PC will not and you can check them as well.

If you want an SD card to work on a specific phone, why wouldn't you format it on that phone?

Is that specific phone using a special unknown partition system for the card? I don't think so. The phones are this days build with market standards including SDHC and SDXC compatibility. SDHC natively use FAT32, SDXC natively use exFAT. Not all phones support SDXC so the card have to be formatted in FAT32 to make it functional and the only way is to use specific application on PC. Formatting the SD on PC also is more efficient than OS of the phones and the main reason is that OS of any phone can't verified a faulty or fake SD card so you can losing data without even know why.

Sorry man, you are usually on point, but with this you are talking nonsense.
I have never seen or heard of an Android phone which didn't use FAT32 or exFAT, nor one that made arbitrary partions. Further, if the phone doesn't support exFAT, obviously it won't format the card to use the exFAT file system. The bit about a PC being more efficient is just total nonsense. I have formatted several different size/brand SD cards on this phone and others without having issues using them in the phone or a PC or other Android device, even. If you can satisfactorily back up anything you've said, I'll change my mind.

I make you and example, I got HTC HD2 with latest Android ICS ported from NEXUS, it not support and it not recognize a 64GB SDXC in exFAT, the only way to make working that card on HD2 is to format it in FAT32 on PC.

Right, but a phone which support exFAT and FAT32 as well will not format the exFAT card to FAT32 end even if he dose the card have huge risk to be compromise. Speaking from experience.

I never said you CAN'T format the card on the phone. It will work anyway but on PC the formatting will be more deeply efficient because you using specified application to do so. On High-End phones the formatting can be good too but you can't say is well done like on PC.
All the Sl..ts making Blo..bs, but there is always someone who do it much better! Am I wrong? :laugh:

let's go back to the topic.I have the same problem on my Z1 as well.
will this related to a slow (class 4) speed sd card?

Absolutely not, the class of the card is not an issue at all. If you have a SDHC have to be in FAT32, check it, just in case. The partition can be corrupted then will be recommended to format the card how you like.
But if your problem is the same as OP mentioned with the same application, to me the app is the main problem. Try to move the files with different application or use different media player to see if the issue still there.

I have put the 32GB cardin my Tablet Z and it's working without error but I can still not get anything over 16GB running on my Z1
Seems a bit strange to me unless it's a random 4.3 problem though I haven't heard any wide spread issues

Yes, seems a bit strange and I will suggest to check the card on PC with h2testw, just in case. If everything is ok with the card then is your phone and probably Android it self, in this scenario I will consider to flash different .290 FW.

I'm using 32GB SanDisk extreme uhs1 and never had a single issue. (well, once cos it was from a faulty batch, but your card doesn't seem to have any of my issues before replacement)
Don't use media go. I think that that's what ruins your music by encoding it like iTunes which z1 doesn't like.

Thanks for your answer.
I read somewhere - don't remember where unfortunately, that SD Cards above 32GB (SDXC?) needs to be formated in FAT32. Is that what you mean? I've heard too, that some custom ROMs requires some other SD Card partition - extSD or something. Then when I'll format new card in FAT32 is it still possible to flash custom ROMs and will they handle this card?
Thanks in advance for your answer

i think that fat32 format will work for sure both on stock and on custom roms, but exfat needs additional drivers which are not present for stock, so will only work on (most) custom roms.
