How to format the Mini SD card

Hi guys
My 2GB Mini SD card is not working. I have a Trinity - Orange SPV M700, I wonder if anyone could tell me how to I fromat it and which FAT system to use?
Sorry if this is a stupid question, but I did try to use File explorer and looked everywhere in the Settings section.
I am thinking, maybe I need to use my card reader in the computer or do I have to buy a 3rd party program to do this?
Any idea
Thanks

Using the cardreader in your computer is fine. Use the FAT format, not FAT32.

Why not FAT32? I've been using a 4gb miniSD fromatted in FAT32 for months without a problem.

If You don't have a card reader or an adaptor for the Micro-SD You can do it via wm5 storage. FAT32 should be better than FAT.

I also had problem with SD card (2Gb). Then I used one program for formating Panasonic SDformatter an now I don't have problems anymore.
Link: http://panasonic.jp/support/global/cs/sd/download/sd_formatter.html
Try with this program.
By

As you may know, the SD specifications are not open but must be licensed and are protected by NDA's. Therefore I pesonally can't say for sure whether or not FAT32 is within the SDA 1.0/1.1 standard, but I would guess that it's not.
It's true that using FAT32 seems to work with most cards and controllers in the PPC world, but apart from eliminating the 512 files limit, I don't really see any advantage over FAT.
FAT32 is not a 'high performance' filesystem, so in terms of read/write speed it doesn't give you anything compared to FAT.
If you use a 4GB non compliant card, then of course you must use FAT32, since FAT only allows for 2GB.
So in short, unless you can't live with the 512 limit, I don't see that FAT32 will give you anything over FAT, and when you use FAT, you are sure to be within the standard.

Thanx for nice info, if that's true, FAT32 is the only option user may have when formating card, this limit is a way to small !

Please note that 512 is not the limit of the total number of files that can be stored on the card, it is the max. number of entries in the root directory.
The max. number of files that can be stored on a FAT filesystem is 65517.

thank you for clarification, is there a way I can already check in what format my card is formated?

If it hasn't been reformatted since it left the factory, then I think it's safe to assume that it's FAT formatted.
If you want to check, then put it in a card reader and look at its properties (assuming your PC is running Windows).

i'm using Windows XP, but in my computer my pda is listed as a windows mobile phone and if right click the storage card, there's no option to format it...what should i do ?

Partitions in wm?

Hello everybody,
Does wm support partitions?
So can I split up my 8 gb sd card into two partitions of 4?
Or does wm not support this?
Thanks!

Hope you don't mind me asking, but what for ?

E.g.
Partition one:
Haret > Android
Partition two:
Multimedia stuff + wm
or
Partiton one:
Multimedia
Partition 2
Program files and stuff

There is no need as both Andriod and WM6.x can see Fat/Fat32, which I presume your SD card is formatted.
If you want to separate your media from any programs you want to install on the sd card just use a different folder.
Plugging your SD card into you TP2 is the same as plugging it into your desktop / laptop whatever the OS.
Would you partition a SD card that was plugged into your desktop ?

If you want to partition the SD, try it and let us know... however i think that it will appear as 2 storage cards in explorer.

I will give it a try

It is possible but not usable...
I also searched around on the internet and it works
But I am back at one sd card since I find folders easier than 2 storage cards.

I know exactly where you're comin' from, man. After I get a 16GB class 6 microSDHC, I intend to partition ~8.5GB as NTFS ('cause I'd like the the max capacity to hold a full DVD DL disk) to handle larger file transfers btwn desk/laptops. And, I'd still have a whoppin' ~7.5GB to be used by the tele as FAT32...'just haven't made that microSDHC purchase yet, but I'd imagine it to be plausible.

I remember some time ago on Aximsite or another older related site reading how to format NTFS and use a Compact Flash card on Windows Mobile. I did it on my Axim and Ipaq at the time, and kind of remember it working.

I know. However, if there're two partitions, NTFS @ ~8.5GB and FAT32 @ ~7.5GB, then I'd imagine that Windows would see the storage card as two drives, while Windows Mobile would see the 16GB, storage card as ~7.5GB. Anyone, please, do correct me if I'm wrong in my assumption.

This has made me wonder, too. Why does WM refer to "Storage Card 1" occasionally when inserting/unplugging memory cards...? It kinda implies that there is room for multiple cards at the same time...????
Chris

i partitioned my 16 gig hard drive and installed linksys on one partition so i can plug into my computer and dual boot from my phone...
i dont really see a reason to create multiple partitions to have the same function as folders (ie seperating media from doc, ext...)

You would not gain anything by formatting NTFS other than the ability to set NTFS permissions in Windows. A movie can be stored on a FAT/FAT32 partition with no ill affect on usability. Also, when you purchase any type of storage, the actual formatted size is usually smaller than the advertised size. So if you buy a 16GB card, you will most likely end up with around 15GB max of usable space. I would not plan on having 7.5GB of free space after creating a 8.5GB partition.

No, you'd also be able to support files larger than 2GB. And, I know it wouldn't be 7.5GB, that's why I'd said about (~). Prob more like 6.8GB, or so.

I know NTFS doesn't work on Windows Mobile. However, I would assume that if you were to make two partitions, one NTFS, and the other FAT32, the Windows Mobile device would show the FAT32 partition, while a Windows dsktp would show the microSDHC as two partitions, NTFS and FAT32. I've ordered a 16GB microSDHC Class 6, and I'll post my results after I receive, partition and format the card.

Okay. So've received my 16GB microSDHC Class 6, and have partitioned and formatted with Paragon Partition Manager Pro v9.0, and have...
Partition 1 - microSDHC N, 8.61GB NTFS
Partition 2 - microSDHC, 6.24GB FAT32
The device sees the FAT32 partition, as intended. Windows (Vista), however, shows only the 1st partition (NTFS) of the microSD, even when using the device in Disk Drive USB mode. Disk Management sees the FAT32 partition, but no matter what options I select, I'm met with
Code:
An unexpected error has occurred. Check the System Event Log for more information on the error...
At this point, I just need Windows to allow me to give the partition a drive letter. Any help would be greatly appreciated.

in the start search bar type computer managment then go to storage/disk management select the disk and then right click and change letter.
thats supposed to let you change the letter i have to deal with this alot at work with all the network drives and my externals
hope this helps

How to format 64gb micro sd card to Fat32 to work on SGS3

Hi guys,
I faced a problem with my 64gb. Sandisk micro SD and I solved the issue and I thought about posting the solution here that might help some of you.
so... the issue I faced is how to get TWRP recovery or CWM to mount my Ex sd card.
basically the problem is that the card is formatted in exfat or NTFS and in both ways it won't be recognized by TWRP and the only way to formate it in fat32 is by only one software because windows can not format more than 32gb in Fat32.
and here is how:
first: download EaseUS Partition Master Home Edition from this link http://download.cnet.com/EaseUS-Partition-Master-Home-Edition/3000-2248_4-10863346.html?tag=mncol%3bpop&cdlPid=10982635
Second : Now you can see a list of all of your hard drives. Note the one highlighted in blue on the grid. This is my 64GB MicroSDXC card in my USB Card Reader. Obviously the location of your card in the list may differ dependant on the number of drives in your computer
You’ll need to right-click on the drive in the list representing your 64GB MicroSDXC card and click “Format partition”
Third : You need to select FAT32 for the File System, and 32KB for Cluster Size.
EaseUS doesn’t immediately apply the changes you specify. Instead, it queues them up so that you can review and revise them before you commit to having the program affect those changes. then we need to press the Apply button.
that's it ... now you can enjoy your 64gb MicroSd and you can mount it in TWRP or CWM recovery .
your welcome

I've tried this method, my card became 32GB
Then I put it into my Galaxy Note, it saw it also as 32GB, then I formatted the card with Gnote, then it became 64GB again
I was planning to create two partitions with minitools formatting tool, one was supoosed to be 16 GB FAT32 and the remaning part would be 48GB NTFS, and I was planning to use, Paragon NTFS to mount that NTFS partition on GNOTE.
But because after formatting on PC it became 32 GB I couldn't do that.
Any suggestions ?

thanks so much for this. I just bought a new 64 gb card for my phone and it "corrupted" on me twice. I plugged it in to my comp and it was exFat. Followed the directions here and formatted to fat32. Now I have to copy my files again. I hope this works. Oh and according to my phone, there is no update 4.1.2 for it. I am on 4.0.4 and it cannot find any updates so that doesnt really work for me.

THANK YOU!!
I had been trying to do thiis for 4 hours when i saw ur post! Thanks sooo much..at first i got an error while formatting, but then i quit all other applications as recommended by the software and it woeked perfectly on my HTC Sensation. Thank You Soooo much:laugh::good:

I was looking to format my card to Fat32 so I can use a Paranoid Android Rom. What happens when I want to flash another ROM and the new ROM is a Tochwiz Rom... Will I need to unformat the card or reverse it someway? I'm a newbie to this stuff.

No. Touchwizz roms and aokp/cm10 roms can both read fat32 sd cards. Because exfat is licenced from Microsoft AOKP can't incorporate the drivers needed to get exfat formatted card to work.
Short story is both roms can read/write to fat32 formatted sd cards. Only Touchwizz roms can read/write to exfat formatted cards. Unless you copy a lot of single files over 4GB in size stick with fat32 formatting.

You can still use your card normally. I've done the inverse way (Touchwiz to AOKP) and works too.
The point is: Touchwiz based ROMs have support to FAT32 and exFAT. AOKP ones have support only to FAT32.

That's another point OP have forgotten. Your card reader must support microSDXC cards. Most readers support only microSDHC and these are maximum 32Gb storage. microSDXC has elevated this limit to 2TB. I had to buy myself a new card reader due to that incompatibility.
There's a fragment in Wikipedia which explains this situation:
SDXC cards are pre-formatted with Microsoft's proprietary and patented exFAT file system, which the host device might not support. Since Microsoft does not publish the specifications of exFAT and its use requires a non-free license, many alternative or older operating systems do not support exFAT for technical or legal reasons. The use of exFAT on some SDXC cards may render SDXC unsuitable as a universal exchange medium, as an SDXC card that uses exFAT would not be usable in all host devices. Since the FAT32 file system supports volumes up to the SDXC's maximum theoretical capacity of 2 TB as well, a user could reformat an SDXC card to use FAT32 for greater portability between computers (see below). FAT32-formatted SDXC cards can be used in a host device built for SDHC if the host device can handle 64 GB and larger volumes.

[Q] Doesn't read Ext4 neither NTFS for the sdcard, wtf?

Ok, android is supposed to be just fine with Ext and NTFS right?
Well i've got S4, kitkat 4.4.2 and 64GB original super fast microsd card and guess what, i formatted it first Ext4 then NTFS because i needed more than 4GB files and for both it says "SD card is blank or has unsupported filesystem."
both times formatted under linux desktop PC
the default formatting from the phone seems to be either FAT or exfat but files over 4GB can't be written. (exfat is supposed to do over 4gb right?)
So, what i'm doing wrong?

Official Galaxy S4 doesnt support NTFS (not sure about Ext4). but there are some custom kernels that can deal with NTFS.
I found this on wikipedia:
exFat advantages: File size limit of 16 EiB–1 byte (limited by volume size), raised from 4 GiB−1 byte in a standard FAT32 filesystem.
so I guess yes it can handle files more than 4GBs, I haven't tried it myself.
Use the official SD formatter tool, it formats cards with 64 GB and larger using the exfat system.
just google: official SD formatter

I Always format my SD cards using Minitool (PC app). Never missed a beat.
If this doesn't work I still think it's a fake SD-card

well it's not, thanks for getting the thread in the wrong direction though!
so does the default bult-in android formatting do FAT or exFAT? It doesn't seem to be possible to tell from the phone?
So, seems like the only way forward is to format it in exFAT?

I am pretty sure it will only format in the style it was originally eg. Original setup of fat32 it will format fat32, if EXfat it will format EXfat.
Ext,1, 2, 3, 4 are all native to android (Linux) so ext4 shouldn't be an issue.
When I formatted my 64Gb card sd formatter did not format it to EXfat I had to do it manually. Please not that windows Xp does not directly support EXfat you need to manually install a patch and then manually format the sd card via cmd window
You'll have to confirm the command but it's something like
Format x: /fs:exfat
This is what I had to do on my old Xp box to do the job.

Micro SD card wont be mounted by Samsung Tab a6

So I have a Samsung Tab a6 7 T280 wifi and I've inserted a MicroSD card (128GB). I've done this with the stock os first and I just got the message card can be removed safely. and it wouldn't let me mount it.
Now I've installed the Tinker V5.1 Stock Rom over it and it still happens. (wanted a faster os on it).
I can reformat the card with twrp to be ext4 or exFAT and it doesn't change a single thing. if I insert the sd card I get a quick preparing card and then instantly the message card can be safely removed. clicking on mount sd card in storage from settings doesn't do anything except prompt same message.

I'd try a different sdcard.

Okay, so I hope I can help, I have the SM-T280, I do not use Tinker ROM, instead I debloated my stock ROM and use an SPA kernel by @_mone. If you're trying to extend storage to your tablet, you'll need to use a PC to partition the SD card two PRIMARY partitions. I used on Windows MiniTool Partition Wizard (free), and I used a FAT32 partition and an ext2 partition. With the stock ROM/kernel I had problems using ext4 or extFAT which didn't make sense to me but it is what it is, and I used the app Apps2SD to handle all the work.
The main thing, you need to make sure your SD card has TWO (2) PRIMARY partitions.
Good luck.

I used on Windows MiniTool Partition Wizard (free), and I used a FAT32 partition and an ext2 partition. With the stock ROM/kernel I had problems using ext4 or extFAT which didn't make sense to me but it is what it is, and I used the app Apps2SD to handle all the work.
The main thing, you need to make sure your SD card has TWO (2) PRIMARY partitions.
Good luck.

What about the Sizes? As in one partition 60 GB the other one also 60 GB ? Or the fat32 partition 1 GB and the ext2 the rest?

FAT32 is not for large capacity storage. Use exFat. There isn't much point in having such a large ext2 partition. It's incompatible with media transfer protocols unless you use a Linux system.
This device fully supports exFAT. I use a 64gb sdcard no issues.

I wouldn't think so, I'm sure it supports 128gb cards.
Just partition it into to halves. First partition exfat. Leave the other unformatted and see what happens.

partitioned into a 40 GB exFAT partition and left rest unpartitioned. Didn't change anything. if I pop it in the tablet I get a short preparing sd card notification then immediately an SD card safe to remove notification...
I'm really confused by this. The tablet is new so I doubt that it's broken but I don't know. Do you know if there's a way to check any kind of logs on Android like dmesg on Linux as an example to see what happens with the sd card?

It's best just try out another card to rule out the card.

Nobody can lend one for a few minutes? Or try the card in someone else device?

So I have a Samsung Tab a6 7 T280 wifi and I've inserted a MicroSD card (128GB). I've done this with the stock os first and I just got the message card can be removed safely. and it wouldn't let me mount it.
Now I've installed the Tinker V5.1 Stock Rom over it and it still happens. (wanted a faster os on it).
I can reformat the card with twrp to be ext4 or exFAT and it doesn't change a single thing. if I insert the sd card I get a quick preparing card and then instantly the message card can be safely removed. clicking on mount sd card in storage from settings doesn't do anything except prompt same message.

According to Samsung, the T280 will support a 256gb SD card BUT I know from experience that SD cards over 32gb can be VERY touchy. If you use a PC to remove all of the partition and then let the tablet try to do its own formatting and it still doesn't work, I'd say you have an incompatible SD card. That doesn't mean the card is bad but that it just won't work in the T280.
As an example, a Samsung EVO+ card (which can be found on eBay for $30) will probably work while a "no name" card from China, probably won't.

I always use Samsung EVO cards and they always work perfectly. Price per GB they are very reasonable too.
