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

listen if u are for real then please do a screen grab of your pda reading your big cards, and a quick picture using ur pda and post up that pic of the magic sandisk ultra 4gb that even they the manafacturers say isnt around, yet you say you got it from their factory but they are not releasing it for quite a few months, trust me memcard manafacturers do not need tht much time to manafacture stocks before they supply them so me thinks you are a little deluded

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] Installing a new SD card

I have just ordered a 16GB SD card to replace the 8GB one I have.
Do I need to format the new card in the phone before transferring the old data?

You have to format it somewhere to be sure you have correct cluster size.
Try card after that with free SD tools (http://veluscek.amebis.si/index.asp?selektiran=sdtools). There is free market link.
Regards, Ales

I am also purchasing a 16Gb SD card . I was going to format it using the phone. You can unmount the sd card and then format it. Is this not a good idea?
I was also going to copy the contents of my current card to my pc, and then copy it back to my new SD card. I am assuming this is the correct way of doing things.

I just changed to a 16GB Class 2 about 2 weeks ago. I just copied everything from the 8GB to my computer. Put the 16 in, and copied everything from the computer to the 16. Everything is working fine. No formating. I did check the phone before copying to it (16), and the format option was not selectable. It was grayed out, so I just copied.

would upgrading the stock 8gig sd card to a class 6 make any difference?

You'd probably only really notice a big difference when copying files from the PC to the phone. Don't think you'd see much of an improvement when opening anything on the phone.

If I'm not mistaken, mine is already upgraded (so-called) to class 10 from my previous phone. I however do not notice any difference in performance.
I think suddy86 is right. Even if there is, I guess it would be hardly noticed.

I have purchased a class 6 card. It was only a couple of quid more than a class 4. Its a Kingston SD Card, so should be good. Didnt fancy buying an unbranded cheaper card.

Another question that I am curious about. Can a nandroid backup made on a 8GB sd card, be restored on a 16GB card?

i believe you can just copy the contents of the 8gig to the 16gig (unless its a gold card)

My arc cannot recognize formatted SD cards, help?

I've tested two sandisk class 4 SD cards.
If I format it to fat32 and partition the space(to use link2SD), my phone refuses to use the SD card and says it's not there. I use minitools for partition and the official SD card maker software for formating. I did everything by the book and tried multiple options(different labels, ntfs, ext2, etc.)
A fresh, unallocated space card works perfectly fine however.
My phone is rooted and unlocked bootloader running softMIUI rom with a modfied power saving blend kernel.
Please help! This is confusing the hell out of me.

Was looking at your post and I decided to grab a few of my MicroSD card 1gb, 2gb, 4gb, 8gb and 16gb....
I formated all of them on windows .... right click format, all default settings... Fat32. These are MicroSD cards that have had information on them... they all run fin on my arc. All different brands.
This leads me to believe that there's possibly either something wrong with the MsD card or the reader on the phone.

Solved it
Did this:
Changed the partition id to this:
"0*06 fat16,greater than 32 mb"
and made the second partition fat32 as well.
Removed the 100mb linux swap file partition I created....not sure if that was necessary.

partitioning sd card

I have been reading that partitioning your SD card before installing roms is good idea. I have a 32 gb card and was thinking of partitioning using ROM manager. What is the ideal space for partitioning and ideal swap space?

i have the same size card in my evo and i use a 1 gig swap partition ...and it seems to like it also ....u can try that or try it like this
1. fat32 remaning space on card
2. ext2/3-1 gig partition
3. linux-swap -100mb partiton

What about the partition size? Also will partitioning erase my SD card?

Here is a guide.
Plus I would not use CWM. Use Amon RA.
And yes this will wipe the card. Back up to your pc.

Thanks! I will back it up before I partition it.

i have a 32 gig class 6 pny card and it works fine i used to have a class 4 and 6 sd 16 gig they just seemed slow but yes i don't see why that wouldn't work,
I've gotten nothing But negative reviews about San disk cards ..personally i wouldn't trust them so try to stay away from those lol and some SD cards pull too much current remember that.make sure u set ur sd card read speed to 4096
and that is a cheap card i am about to go buy up a few and check em out lol hope that helps

Update:
Well I just partitioned my new 32Gb SD card class 4:
swap 64Mb
ext3 2048Mb
fat32 the rest
I'm using Energy ROM with Anthrax Kernel and it works like a charm.

Swap
whats the best swap size to use?

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.
