Any way to partition external sd card without pc? - General Questions and Answers

Thing is, I have this 64gb sdcard which I need to create a 32gb or so ext4 partition on and leave the rest for fat32 but I have NO access to a pc whatsoever for two-three days and I really need to partition today, on the tablet.
Twrp doesn't have any partition option and rom manager does at most 512mb partitions. Help?

my rooted tf201 has fdisk and mkfs.ext2 on it. Perhaps you could use a combination of those to format your disk without using a pc.

Doesn't matter now. I've already sold that piece of metal crap and bought a wifi Nexus 7 32GB ^^

[Q] Partition layout on ICS?

Or more to the point, does anyone think they will fix the way the TF memory/partitions are based with the ICS "AiO" Android 4 revision?
While its not an operational annoyance for me (IE most everything works fine), I HATE the fact that the internal memory is mounted as the sdcard instead of as internal memory (like any other device I have used)
I hate that out of 16GB I only have 11.xGB to use (especially when my ROM size before install is only 180Mb extracted... Stock is like 400Mb+) and cant use something like Firerats (at least not that I have found with searching, and yes I know firerats is basically just a repartition tool for MTD not eMMC or anything else) to repartition it to reclaim the wasted space...
From what I understood (and i could be wrong here), its only setup with the Internal memory as an SD instead of... internal memory... is because of Honeycomb, and that the layout is similar to other devices in that its a single memory chip for the internal/system/sd like any other NON Honeycomb device only the internal memory is... well internal memory...
So my question is that can anyone in the know on this subject help me out here...
AFAIK we get one chip for storage. Most stuff expects /sdcard so it makes sense for HC/ICS to be putting our /data/media on /mnt/sdcard with the FUSE thing.
And I can't see any really good reason to change what the norm is on TF101.

I think you'll find that on Froyo/Gingerbread phones with internal memory as well as an SD slot, internal memory has always been mounted as /sdcard/ or /mnt/sdcard/ - the external card is mounted as a subfolder under that. This is for the user's convenience. Can you imagine how it would work to mount the internal memory if there was no external card present otherwise?
I seriously doubt ICS itself will solve the niggling problem of external SD mounting on our TF101s, but Asus may well change the layout so it's under /sdcard/xxxx/ to help matters.

I could understand ASUS placing the internal storage as /sdcard since most stuff does expect/save to /sdcard automatically. Being that the tablet has an advertised 16GB of memory, ASUS probably believed that your every day average Joe wouldn't go out and buy an sd card.

I guess I was a bit vague, I dont actually want it as extra storage or partition, I just want it all as /data instead of /sdcard... all the phone I have and have used (which I admit arent the latest, the newest I have used was an 8GB phone I cant remember the model of) so far didnt actually use /sdcard they just used /data... I have an SD card specificly for being an SD card... I hate having to either remap or manually use a file manager to get my TB files or anything else that uses the fake /sdcard instead of my actual SD card... id prefer all /data bleh...

it IS all on /data. /sdcard or /mnt/sdcard is a FUSE mounted filesystem from /data/media. All space accessible on /sdcard is also accessible on /data.
EDIT:
All my android phones do not do what you claim either, the internal mem is mounted as /mnt/emmc and /data is a 2GB partition on the emmc

ok, lets put it this way, nothing is mounted under /sdcard when i look at my phones without my SD card in them... get me now? when I go to phone data I have 7~Gb free listed for apps and such, there is no SD card listed, I dont know how to put it any other way, there is NOTHING in the removable or sdcard directory (the removable doesnt even exist on my phones) until I put one of my MicroSD cards in...
ergo, data is a 2gb partition you say, cool! I want to eliminate the fake sdcard partition then and combine it all into /data! I want the programs that store data on to the /sdcard to ACTUALLY GO TO MY DAMN SDCARD...
what phone do you have that has 7GB of /data/ ?

get it, /sdcard is DIRECTLY linked to /data/media, you lose no space what-so-ever to the /sdcard link.
further more show me a phone that has all the space in /data that is listed as having 16/32GB mem, it is pretty standard, my sgs was /mnt/sdcard, until I flashed CM7 when it was changed to /mnt/emmc, still not seen what you say where a device has all its space as /data
im not saying its not standard, im just saying (as is the original request on my post) that I dont want it mounted as SDCARD because I want my damn programs and sdcard data to do to... you guessed it, my ACTUAL SD CARD...
when I make backups with Titanium Backup, I want them to go to the MicoSD card I have inserted like they would with any other phone/device without having to **** with anything else, same with game/app extra data that uses SD card storage...
I played with an SGS2 today and while i didnt get to play with terminal, I ran TB and the backup went to the MicroSD card inserted and not the internal memory... unlike what the TF does...

And that buy now after years of PC's with X GB hard drives that they would be used to losing some to the OS and recovery partiton. Especially since Windows and major Linux distro's have gotten excessively FAT.

hate to break it to you but the SGS2 has a smaller /data partition, then the rest is mounted as /mnt/sdcard.
you do know that TiBU does allow you to select where you save your backup to right?
And for programs that don't (/mnt/sdcard/kindle for example), you can symlink the folder(s) they want to /Removable/MicroSD/(kindle) quite easily.

I agree, its really annoying. A good example is dolphin browser. When I go to back up the settings and bookmarks "to SD" I have to hunt and peck in a file manager to find the stupid file and move it to my actual SD card. I am not at all a fan of the simulated SD card.

yep, it annoys the everliving piss outta me, and while programs like TiB can "select" the location, and you can make "simlinks" for specific apps, I dont want to have to go through the hassle, I want to know that any program I use, when it requires the MicroSD, or normally saves to the MicroSD, to save to my &^*^&*%^%& MicroSD...
its as simple as that...
Guys, chill out, it's just a forum on the Internet.
Best alternative to dealing with the design: make a patch se or custom that screws with /init*.rc files accordingly. Main problem (give or take figuring out how to do it) would probably be how the system would react when no MicroSD card is mounted.

**UPDATE** SanDisk 64GB Genuine micro SD Ultra Mobile class 10 SDXC

Hi Everyone
I bought the card mentioned below from ebay.
http://www.ebay.com.au/itm/28094386...X:IT&_trksid=p3984.m1497.l2649#ht_1906wt_1163
I have a couple of questions:
- Why is the transfer rate so slow when transferring files between computer and on to the SD card? It's like up to 2 MB/second.
- I used SDFormatter to format the card. The settings that I have used are Full Erase (Overwrite) and Flash Erase (OFF). When finished, I inserted the card and it's saying SD card damaged? I don't understand. Initially, I converted the file system from exFAT to FAT but the SDFormatter converted the file format back to exFAT.
Any help would be appreciated!
Thanks,
Sam

Hi, Thanks for your prompt response - So, since now the partition is back as ex-FAT, I would have to convert to FAT and then format the card or would it convert to FAT when I format the card in recovery?

Uhm, little question at this occassion cause I only know about FAT12, FAT16 and FAT32 (called vfat by linux when combined with long file names) so far -- what is ex-FAT?
But apart from that: formatting means writing a new file system to a block device [at least nowadays, in earlier times it could also mean write a new sector geometry on a harddisk]. So, it doesn't matter what flavour the old filesystem was.

Some of the reading that I have done with regards to these new types of SD cards from Sandisk, ex-FAT file structure is what they come with and our mobile phones are not eqipped to handle this format so hence the need to convert it to FAT. Now what ex-FAT is, I'm not sure. I'm not at my PC so will have to do some more reading on that one.
Are you sure you actually have a 64gb class 10?
There are A LOT of fakes on ebay where they take a class 2 8gb card and put a class 10 64gb label on it. Most are good enough painted on labels that you cant tell.
They even partition the card with fake info so it says its got 64gb of space....though it fills up with 8gb.
Be very careful with those ebay cards.
Anyway, that might be the reason you are getting slow transfer speeds.

If you can, go for Toshiba, the last time i heard most of the card are made by Toshiba, the other brands just slap a sticker onto it.

Just wanted to add to this conversation, although you normally will not run into this format. Because of Windows Phone 7 on the HD2 I know about this. If the card is formated in a RAID format you will have do w low level format on the card first before you can format it fat anything. So yes rarely it does matter what "flavour" the old file system was. That it should be mentioned.

Well, I got it from a Top ebay seller so I was hoping it'd be genuine. The space on my card when I first formatted said 59gb free.
Please advise what should I do? I will let seller know and see what happens?
Thanks,
I have one other question. I have found Patition Wizard by MiniTool and if I create a partition on the card as EXT4, will our sensation recognize the card?
I have created a partition on the sd card as FAT32 but the phone is still not recognizing the card. arghhh!

Most probably you got a low classed sd card and also try formate from your phone using any compitable file manager or using the phones builtin system.
And to test your sd card, google for "h2testw" and test your memory card.

I can't format from my phone because it is not recognizing it and/or having issues with being mounted. Now, it's not even recognizing it when I put it in the adapter. The windows 7 format pop windows says 'Unavailable capacity'. I think it's ****ed Thanks, I'll search for the memory card tester.
Can someone please recommend me another one? 32/64GB. Maybe, I should get a 32GB since a lot of people are having issues with 64GB. The only reason I got 64 was that it was selling cheap. 32GB should be plenty for my needs.

I have tried using SDFormatter with the memory card reader but it always changed the file structure back to ex-FAT, which is not compatible on Sensation.
@I got 64 was that it was selling cheap:
So tell me one thing, you will drive a Mercedes but you only will pay for a small Fiat?
I have an original Samsung 64GB Class 10 sd-card with no issues. They was not cheap at all.
Things you can do is:
a low level format to be shure..
- tool: HDD Low Level Format Tool 4.25 - www.hddguru.com
- that is the tool i am using for all my memory device since years
set up a new partion and format the sd-card..
- tool: EASEUS Partition Master 9.1.0 Home Edition - Free for Home Users - www.partition-tool.com
- that tool can format every type and size
Ok that all is running on my 2nd w7 pc. Not my favor OS
When this all is not working with your sd-card, then you have possiblea a fake card.
The low-level-format tool looks deeper then your windows property.
When you have a fake card the LLF tool will stop working after it has reached the max of sectors.
You could have got one from amazon thats what I did

[Q] Galaxy Tab 2 7.0 MicroSD 64GB?

I know the specifications list it as supporting up to a 32GB MicroSD but is it possible to use a 64GB MicroSD card in it?
I am doing it right now, but from what I've read searching on here it has to be formatted in a different device because for whatever reason the tab 2 won't reformat it on it's own, but once you've got the card formatted to fat32 (you need a special app to do it on windows) you should be good to go in the TAB.
Here is a command prompt formatter that worked for me.
1. Unzip the file to the root of C:\
2. Mount your 64GB card on your PC and take note of the allocated drive letter (e.g. e:\)
3. run command prompt on PC (search for cmd.exe)
4. get to c:\ (I think cd c:\ will do this)
5. type fat32format.exe e:\ and press <return>
(where e:\ is the allocated drive letter from step 2, so if it mounts as f:\ you would type fat32format.exe f:\ instead)
This should then format your card as FAT32 which works fine in my Galaxy SII so there's no reason I can think of why it wouldn't work in the Tab 2 too.
This is all at your own risk of course - I won't be responsible if something goes horribly wrong and you kill your card, PC, Tab or anything else...sorry.
Did anybody have any success with this? I am looking at buying the Tab 2 7.0, but I need a 64GB MicroSD.

Does anyone know if the need for the sd card to be formatted as fat32 (or, as the case may be, exfat) is also true of the Note 2? I have both devices (plus a Note 10.1, with which I have no problem using the 64gb card right out of the package). The Note 2 and the tab 2 both have issues trying to read a 64gb card. They recognize the card and its max size, but renames copied files and folders or doesn't copy them at all.
Thanks.

Will I still get all 64gb of the card when it is formatted fat32? I hear fat32 supports only up to 32gb partitions. I know I will never get the whole 64gb due to file system usage but something like 59 or something gb should be fine

[Q] Impossible to partition my new micro sd card 64gb

Hello, i have a problem with my Galaxy Tab 2.7.0 (GT-P3110) with omni-4.4.4-20140820-p3110-NIGHTLY rom installed.
I have bought a SAMSUNG ELECTRONICS IT - MB-MPCGC EU (Samsung microSDXC 64GB Class 10 ) micro sd card and I used it out of the box in my PAD without need to format it.
(in Storage i have found it under SD CARD tab (Total Space 58.45 GB not sure if this is ok) but i don't have the option for Formatting it (only Unmount and after it Erase or Mount)
I can see it with Windows 7 via USB MTP mode and copy files on it but not formatting it
I have tested this card with Sdtools and Sdcardtester on the tab without any problem
Now my problem is that i want to use Link2sd to move my apps on the Sd card but i have no way to make the 2 needed partitions on the it
I have tried to see if Mini Tool Partition would able to see the card from the tab's USB in MTP mode without success, i have tried to use a Sd card reader directly on my Pc with the same result (with another microd sd i was able to have it connected in Windows but this card is only 4 gb)
I have tried this also on a different PC without any luck
I tried to make partition on the card in recovery mode (tried with TWRP_2.7.1.2 and PhilZ-Touch-Recovery_6.57.5 and CWM_6.0.5.0) but in none of the 3 i have found the Partition SD card option inside the Advanced menu...
So after trying everything i'm lost
If anyone have any advice or can give me any help on this i will appreciate it

Your English is just fine
The dying honestly depends on what files you need on your sdcard compared to the source the apps you plan to move to your sdcard will take up. I'd either make them both 32GB or one 16 gb and one 48 gb, the larger one obviously for whichever partition needs to be bigger.

[Q] Is fat32 the only filesystem supported for microsd?

I tried formatting to ext4 and the phone did not recognize the card. Just wondered if anyone else had sucessfully tried any other filesystems?
Right now 64GB microsd's seem to be the best deal and name brand versions can be found as cheap as $20-25 where 128gb cards will still cost you $70+ and usually involve rebates at the lower end prices.
Exfat and fat32. I have mine formatted to fat32.
Sent from my Alcatel OneTouch Idol 3 using Tapatalk
Applications that can write to SD card can only write to a SD card format to FAT 32. The system file manager can write to Exfat, but that's it.
Still not all apps will have permissions. I can't get Utorrent to save to the ext sd for anything

Syncthing is the same way...you should still be able to use the kitkat workaround though which is to save your files to a folder under the android\data\<appname> folder on the sdcard since each app has access to it's own data area.
I never knew about this workaround. So i create the folders on my ext sd card?

Try this: http://www.instructables.com/id/How-to-bypass-Android-44-KitKat-external-SD-write-/
damn... i'll try that
how come the sdcard can't be used for anything
camera 360 can't use it to save, there's no option to choose applications installation on sdcard ect.
had to use link2sd to move almost all my apps without error
seriously now...

It can be used if you are rooted...requires adding a line to platform.xml. If you find the thread about what camera software to use I posted some instructions on how to fix it where 3rd party's can use the external sd...or you can google on "platform.xml android external sd".

Blame google, not Alcatel. The external sd card issue is due to Lollipop..
That app makes the same change...you can uninstall it after it modifies the file. Simpler for me to just edit the file and push the change.
I'm on exfat on a 64gb. Works fine.
The 200gb I had in my g3 worked just fine.
Just realized the card cost more than this phone...

My 32 gb HDSC card came formatted with FAT32. I preferred ExFAT, so I reformatted the card using Disk Utility on my Mac. The Icon 3 didn't recognize it until I reformatted back to FAT32. Maybe I should have tried formatting it on a Windows machine. I may try a 64 GB HDXC card that probably comes formatted with ExFAT.

Really not much of a benefit to exfat over fat32...especially if you set cluster size when formatting. I also read about some folks having permission issues writing to the exfat till they reformatted. The samsung 128GB I put in my idol3 worked like a champ.
NooB....Thank Google lollypop for sdcard problems. U can write to sdcard with some apps not all if the code is written for this.
It seems TWRP doesn't recognise exfat partitions if the sdcard doesn't contain a partition table (GPT works, I haven't tried old-style msdos partition table).
This could be partly explained by the fact that, without a partition table, the external sdcard is called /dev/block/mmcblk1 instead of /dev/block/mmcblk1p1
To put it another way, if you want your sd card to be both readable when the phone is normally booted AND when it's booted into TWRP, you have to make a GPT table on the sdcard, and create an exfat partition inside.
=> In windows, it just fell into place after messing around with it for a bit. Your mileage will vary, depending on if you had an msdos partition table, a pre-existing GPT partition table (easiest) or no partition table at all. I gave up trying to figure it out.
=> Under TWRP adb shell, using the image containing gdisk, I did it this way (data-destructive operation !) :
- Use gdisk to create a new GPT table on /dev/block/mmcblk1 (or /dev/sdX outside from adb shell)
- Also with gdisk, create a new partition (types 8300 or 0700 should do) on the device targeted previously
- Then, exit gdisk and use "mkfs.exfat -n extsd /dev/block/mmcblk1p1" (or /dev/sdX1 if you didn't do it from TWRP adb shell) to reformat the partition created previously to exfat format.
However => do NOT use mkfs.exfat command on the /dev/block/mmcblk1 device (or /dev/sdX), else you'll have to redo step 1 again
Also, under adb shell, make sure you don't accidentally wipe /dev/block/mmcblk0 device, else you'll brick your phone !
I hope this helps a few people

Or just keep it formatted as fat32 and skip the above which was my choice.
Just my two cents - why would you want to format SD to ext4? Journaling filesystems don't work very well with flash drives, cells die much quicker.
