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 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.

[Q] XP won't read app data in new micro SD card. Help?

Hi everyone,
I read that the process of upgrading to a new micro SD only involved a simple copy and paste from the old card. I got a SanDisk Ultra 32 GB MicroSDHC (SDSDQUA-032G-U46A) and after multiple tries I cannot get my Xperia Play to properly read the data from the old card once it's on the new card. I've tried formatting the card with the phone, with the computer, and nothing improves (I used FAT32 as the format). The closest I got was the app icons showing up properly but the apps force closing once I started them.
What can I do? Is there a tool that will allow me to transfer everything without screwing up path files in the process?

Anyone?

check the sd card if its fulty(yes there is sd cards that fulty from the shop).
the best way to do it is put the sd card to adapter (sd card to usb) and connect it to the pc.if its not working.take it to the shop you buyed and replace it.

Is the sdcard legit? Did you buy your sdcard from reliable source more info would be nice. Is your sdcard formatted to FAT 32?

Same issue here
Formatted on computer to FAT32. Copied files over via computer, stick the new card in. Phone lags and freezes, apps are "not installed", and when I try to format via the Play, the phone just freezes.
Card is legit, bought from Best Buy, passed all the tests, works just fine using a an adapter (usb and regular sd).

[Q] Micro SD Card problem

Hi there.
I'm having problems with the SD card, is always unmounting with no apparent reason...
When I'm on the Album (or gallery) and I scroll trough the photos (I've got a few) the card is unmounted and I need to take it of, and put it back in...
While I'm copying files from the PC to the card (trough the phone) the same thing happens...
The card is a sandisk class 10 32Gb... it was used on my SGS2 and never had any problem...
Does it worth to buy another card, or someone else is having the same problems?

I think this is a problem with your sd card. I don't have any problem like that.

Can you please tell me what card do you have?
I have already formatted the card on the pc and on the phone, the result is the same...

Weird problem, I own a Goodram 32 GB Class 10 micro sd card and I haven't got any problems with it. You say that you have tried formatting the card. What format have you chosen? Have you tried reset to factory reset your device? Are you on some custom rom or the stock one? Do you have a possibility to check wheter the problem exists with other micro sd card? Perhaps you can borrow it from someone for a moment or you have another one somewhere. Worst case scenario the card port could be damaged.

I have a Kingston microSDHC 32GB, Class 4 :good:

Hi,
I'm sure that's an issue with your sd card. I've had the same issue with my old SGS3 and an SanDisk 64GB sd card. Then I bought a new Kingston 64GB sd card and it works.

I formated in FAT and in FAT32, same result in both.
Im in the stock ROM, totally unchanged.
I already get a new card and I'm testing it now, if it stills get me troubles I will try the factory reset.
Yeah... that is my fear... that the port is defective or something like that

Ok, updating from the previous post.
I've bought another SD Card and although that on the first time that I used it on the phone, it gave me the same behavior, after formatted it on the phone itself, so far so good.
I've tried the old SD Card with an adapter on the pc, and it works fine, no problem at all... so it must be something specific to the phone, I've read that some Samsung are a SD card eaters, so I believe that the problem is related to that (my previous phone was a SGS2).
Thank you all for the tips.

Not necessarily.
Card of class 4 may be good enough for your computer, specially if it is older too, but may be too weak for newest modern phone.

Bootloader error?

Hi,
When I turn my phone on, it sometimes shows up with this message: http://i.imgur.com/vxq4QQo.png
Any idea how to fix this?
Thanks!

That's a recovery error, when there is no MOFD_SDUPDATE
Sent from my ASUS_Z00AD using Tapatalk

Even though the Zenfone 2 supports 64gb sd card the recovery (stock) doesn't recognise the micro sd card if it bigger than 32gb or formatted anything other than FAT32.
You either need to put the OTA file on a 32gb or less micro sd card and flash or format your micro sd card FAT32, doing this will result in not being able to put files larger than 4gb on it.
Lucky for me I have an sd card to micro sd card reader adaptor and a 4gb sd card...

Hi,
Thanks for the suggestions. I'll try those
Edit: Truth be told, I don't actually have the phone yet so I cannot try it. That's a picture from the eBay seller.
I snagged a "for parts" 4GB version for less than $100. If the only problem is it needs to be re-flashed, then I think I got a great deal.

Can't format sd card as internal storage

Hello guys when i try to set my sd card as internal storage it says that the sd card is too slow (its a sandisk class 10 90rw) . (Running Viperone currently) Some way to bypass the message or something ?

If you have a USB card reader, try formatting the card on your computer.

FAT32 would be best for the M8, especially if your card is 32gb or less. That is default for almost all of those sized SD cards as well.

If nobody you know has a card reader, it's worthy buying one to have around. They only cost around $7-8 US.
