4GB SD Card Unreadable

My SanDisk 4GB Extreme 3 SD Card used to work on my PC's SD card reader. The SD card reader read it as a 4GB SD card.
I tried to use it on the Universal and it asked me to format the card to read it. I did not format it. Next I tried to plug it into the SD card reader on the Universal again and again and it would ask me to format it. I formatted it and it read! But sadly only as 1961MB or 2GB card. Next i took it out and tried it back on my PC's SD card reader. Now my PC would ask to format it.... omg. So i tried again and it still asked me to format it. This time the PC tried to format it but it failed. My PC is unable to read the SD card. I used an external SD Card reader and it failed to read my 4GB SD card too!.. omg Universal Destroyed my 4GB SD Card ;( .... and it only reads as 2GB on my Universal.
Can anyone help me get out of this miserable situation.

Alright just before I go looking out for this SanDisk fix utility I would like tell you that SanDisk hasn't officially marketed the 4GB Extreme III cards in North America and Asian Mainland. It comes from Japan so I wonder if i will be even able to recieve support on it or a fix utility. How big is this fix utility? Can you upload it here if you find one for a 4GB extreme III card or post the link please? How the hell does it suddenly become 2GB....?_?
On some SD card readers it wont read too! And on all other places it reads as 2GB and wont go above 2GB. I thought maybe its just a reading issue but it actually reformatted the firmware to 2GB >.< .... I am sueing either microsoft or sandisk on this, like I think enough is enough and both companies have reached their limit on troubling me...always i get imperfect stuff.
I am really stressed out after spending so much money and still having technical difficulties with these things.

I believe using QTEK latest ROM with A2DP has no problem working with 4GB SD card

I have to agree with FOSA. My 4GB Card works just fine. Plus, it worked fine even when I was testing the different AKU 3 ROMs.

Oh no... Both the cards aren't being read by the PC's SD card reader anymore. The PC's SD Card reader will always ask me to format the card but when I click to format it wont, just freezes.
From all my SD card readers only the Universals SD card reader works, only shows 2GB and I cannot load more than 2GB of data on the SD card. I can access the SD card from my PC using the Universal as an SD card reader. My USB card reader wont read it either. All my other 2GB mini-SD cards work flawlessly.
Maybe I should try another ROM and see if the SD card can be formatted back to 4GB and 8GB respectively. I was using a ROM that I was making myself while this incident happened. I think that ROM will need more fixing. For now I will roll back to a stable ROM. Some people suggest the Qtek Official ROM and some say that all the AKU 3 ROM's here work to read the 4GB cards well.
I just got to keep testing eh? Testing and learning how these SD cards function in which ROM?
Panasonic SD card formatter wont work because the PC cant read the SD cards, its like one of those corrupt damaged CD's that you cant even access.

Thanks so much indra. It worked. Both my 8GB and 4GB cards are back to life! The format also returned them to their original 4GB and 8GB state

If you bought the card in high street store, return it.

I am still having the problem where the Pocket PC reformats my 4GB card into a 2GB card and SanDisk is unable to find a solution to it.
Also while using other ROM's my 4GB card is not read? It seems the hardware is compatible to read 4GB cards except the ROM is not designed to do so. For example Helmi's AKU 3.5 ROM cannot read my Sandisk Extreme III 4GB. Now SanDisk also doesn't believe that i have that card because they never marketed it, but they dont know that I got it from their factory! Now that remains a secret how i got it. Its really fast and amazingly I gave it to a few people.
Luckily i found a ROM that reads my 4GB card except the 4GB card is always reformatted to 2GB... Its very confusing because even my PC now reads it only as 2GB....It was working fine about 2 weeks ago as 4GB.
If I can get any help to make this card back to a 4GB please! Thank you for your help ^^

From what I've read some weeks ago on the Panasonic homepage was, that SD-cards following the "old" SD-standard are designed for up to 2GB capacity. Everything above that is non-standard and will likely make problems. (Although there are some exceptions as you can read here on this forum.)
To come around these problems, they invented the SDHC-standard for sizes from 4GB and more. Sad thing is, that the reading device has to support this standard. The Universal doesn't afaik.
You can even read that on Wikipedia:
Some manufacturers have produced 4GB SD cards that do not conform to the SD2.0/SDHC and are incompatible with existing SD devices, and are also incompatible with SDHC devices.

So if you have problems, stick to 2GB cards. They work flawlessly.
P.S.: I first bought one of those 4GB-SD-cards and it was recognized by my Universal as 4GB but after copying approx. 5-6MB on it, it suddenly stopped working. The Universal always asked to format this thing. The PC showed sizes of about 930MB, even the Panasonic SD Formatter wasn't able to do anything about it. So I returned it and got 2x 2GB cards. No problems at all.

Except I cant return it because I got it from Japan and it will be coming soon in retail markets by 2-5 months. I agree the 2GB cards work flawlessly. Except I would like larger storage.
I am using CNET Flash format to reformat the Card except it wont go back to being 4GB. It seems the firmware of the card has been overwritten

There is no a firmware inside the cards that might be overwritten using end-user tools. In your case most probably the card was re-partitioned. Read about MBR and partition tables for details. Quite easy to fix.

Thank you Lurker. I will look up MBR and partition tables. I am really lost on this MBR and partition tables. If you can help me out and just walk me through on how to fix my card i will be really happy. Or any links will be helpful too.

Amsam 810

My Amsam will only read a 2gb card.It is supposed to take up to 8gb.
The AMsam website used to have a patch that was available for download but it does not have it now.
DOes anyone have the patch AMSAM_SDHC_DRIVE_SUPPORT_8G.CAB

I managed to get the driver.
So if anyone wants it send me a PM and il email it to you.
THe only problem now is that it wont work with a 4Gb card.
Although i might be using the wrong card.
The card that came with the phone was a Transcend Micro SD 2GB
The card i am trying to use is a Kingston Micro SDHC 4GB
I have formatted the card to FAT32 and it still wont work.SO my questions are
(1)Are these different cards and thats why they wont work
(2)Am i formatting the file incorrectly ?
Thank You in Advance

be happy
install this cab and enjoy with your 4 or 8 or 16 GB

SD Card

Hi
I have a problem with my htc and i need some help if you can. I recently got a 4gb sd card for my phone and it doest work on it but the card works perfectly on the Samsung Galaxy Mini and the HTC TYTN II that i also have .
So my quastion is this. Is there anything else to do besides the format or the phone supports a special brand of a 4gb sd card??
P.S. please post me a link of a giude on how to upgrade the phone i ve been reading the wildfire section all day today and the only thing i found is the rom section.
Thanks in advance

Your phone could have a faulty card slot. If it's still under warranty, return it and get another one.
As for your other question, here's a link to a list of guides to help you through whatever you need: [INDEX].

Thanks for replying and trying to help.
I am really sorry but i forgot to mention that the 2 gb card that came with it or the 1 gb card from the Samsung one works perfectly on the HTC so the card slot is no issue i also took the phone to the company i purchased it and they said that i have to leave it there to check it but they will charge me because i installed the 4gb card my self
Thanks again for all the help you can provide

What's the brand and class of your 4GB Micro SD Card?
I had problems with a Kingston 8GB class 10 Micro SD Card, it was recognized by the phone but it randomly unmounted the card.
When I bought a Samsung 8GB class 6 Micro SD Card the problems were gone.

The brand of the card is kingston transcend 4gb.
That was my first estimation that the brand might not be compatible but i was hoping that it might be a soft upgrade or an application that could do the job and mount the card because mine it doesnt mount at all.
I will try and replace the card with another brand and see if it works
Thanks for all the help guys.

16GB vs 32GB

Hello will they be any down side to buying the 16GB version to the 32GB version if you plan on adding a 64GB sdcard? what I mean by this will the Device allow me to install all apps onto the SDcard.
Thanks

Well 16gb may not be able to fit all your apps. Thats fine as long as you get an sd card with fast read and write speeds. If you may experience slow dons if putting apps on the sd card.

^ What the poster above me said, plus the fact that in Android 4.4+, apparently there are issues with writing/deleting to/from the external SD card - just something you might want to take into consideration.

you may want the 32gb internal to install many apps/games as most apps are not movable to the externel SD.

128GB Micro SD Card....Do They Work?

Interested in this phone for the specs, and the fact it has root...xposed etc...
Does this phone support and work with 128GB micro sd card.
Was looking at a 32/64gb model in Red.

Hello, this is ASUS_USA. Zenfone 2 model ZE551ML Micro SD Card slot supports up to 64GB

Yes, I am using the Lexar 128 633X in the 551ML 4/64

Here is a picture of the card and the phone.

You should be able to use any sdxc card as the 64gb card is sdxc... If a 512Gb sdxc micro sd card came out you would be able to use this...
And yes I have tested a sandisk 128Gb micro sd card in my xenfone 2...

I am using the Asus Zenfone 2 ZE551ML (4GB RAM, 32GB ROM) and can confirm that a Sandisk 128GB MicroSD card works fine . Mine is formatted with FAT32; i am not sure whether ExFat would be supported as well.

exFat is and OTG USB sticks work fine too... I have a 64Gb OTG card that was working brilliantly with it earlier, shame a friend wanted to borrow it cos I was gonna load it with stuff to do at work tonight...

Looks like Im going to have to pick up a 128gb sd card soon. Thanks for comfirming this since I was wondering the same thing for my Zenphone 2.

I'm running a Patriot 128GB microSDXC myself.

By the way, whats the best type of external microsdcard to use?
Do we need to be choosy in buying??

I always like a good ol' SanDisk

I'm just gonna add a little bit more here, You need a FAT32 formatted sd card for firmware updates if you are doing it manually and haven't rooted yet. The stock recovery won't recognise an exFAT formatted card (which is what most 128gb sd card are formatted) so when you put the update file on your card your card won't be recognised by the recovery.
Rooted with latest TWRP recognises card fine...

In anyone wants to know, I'm using a PNY 128GB card (http://www.amazon.com/gp/product/B00OP2P0ZO?psc=1&redirect=true&ref_=od_aui_detailpages00).
Stock everything. No issues with the ZF2 recognizing the card or accessing.

Pretty sure you can't have any more info than what's currently available. The phone's only been available for a few months, that's as long as testing with 128GB exFAT or FAT32 will indicate stability for. Card size has no impact on a phone's microsd reader, just like sock size has no bearing on the size of a person's genitalia
FWIW I got a 128GB exFAT a week ago and haven't had any issues. If your phone has issues reading any card, it'll typically have trouble reading every card. Special exception is for devices that software/hardware don't support larger than 32gb, exFAT or Class UHS1 speed cards. Your Zenfone2 supports greater than 32gb, exFAT, and Class UHS1.

Our only choices for backups using ASUS backup are internal device or SD card. If we can only use up to 64GB, some backups might not work if they are larger than that (apps and data) or close to that in size.

With unlocked bootloader and root I have no problem accessing the exFAT 128gb sd card even while using TWRP recovery.
Not sure if the newer roms support exFAT or I have a magical Zenfone 2 but it did an OTA update with the OTA file on the sd card ... No renaming of the file was needed...

My model ZE551ML is not reading exFat 64GB card. Can it be formatted to FAT32 or should be replaced? My PC is only giving me exFAT file system when I try to format it!!!

Mine (I think) is formatted FAT32 and works fine. It's just you cannot have any individual files over 2GB in size.
EDIT: Never mind. I just checked via mount command and it is listed as "texfat". Guess I didn't reformat from when I bought the card.

exFat doesn't seem to be readable at all!! Can it be converted to FAT 32?? Thanks.
