Whats the best cache size for a 32 GB SD Card. It's a class 6 I believe. Thanks.

I was just wondering if anyone could shed some light on following.
I bought a 4 gb card and of course that didn't work.
Then bought a 2 gb card and that worked just fine.
Bought a second 2 gb card and that one didn't work, the wizard fails to recognize the card at all. When in the Wizard File Manager there is no reference to Storage Card at all unlike the first 2 gb SD card.
I got an app which looks at the formatting of the SD Cards
The first 2 gb SD card that works has the following formatting:
Cylinder: 242
Head: 255
Sector: 63
_____________________________________
The second 2 gb SD card that does not work has the following formatting:
Cylinder: 939
Head: 64
Sector: 63
______________________________________
The 4 gb SD card that doesn't work
Cylinder: 482
Head: 255
Sector: 63
________________________________________
Questions is - Is there any method to format the 2nd SD card that doesn't work to have the same Cylinder, Head, and Sector structure as the 1st that does work?
No matter what type of formatting I choose via my PC Card reader using Fat or Fat32 selecting different Allocation unit sizes, the C H and S item remain the same.
Is there a SD Formatting utility that would allow me to change that structure? If not, how does one know before purchasing as 2 gb SD card what the formatting format is? The 2 gb SD aren't high density so that shouldn't be a factor.
Thanks.
I canNOT answer almost any of your questions, but in terms of another formatting method, try formatting the 2G card in a digital camera, then try using it on the Wizard. I revived a card that would not even get read in two different laptops by first formatting on a camera.
Also, there is an app SD Memory Card Formatting Software which did not help me, but the camera did.
I have tried several builds but the result is disappointing. None of them can boot when I want to use EXT4 partition for data on it with my large SDHC card (16GB)
My 8GB Class 6 microSDHC runs fine but when I want to use Class 10 16GB card, the system crashes on boot...
I think 15GB FAT32 partition (I created 1GB EXT4 partition at the end of the card) is too large to be seen during Android boot or what?
Do you think it will work when I create only 7GB FAT32 and 9GB EXT4 it will work? Or should I switch the order of partitions (EXT4 first?) (it is not good solution but good for test)
Can someone from cooks help here? Thank you very much.
Firstly, this is the wrong section. There is a Q&A section explicitly for questions like this.
Secondly, I have a 16GB card with exactly this setup (15+1) and it works perfectly. Your card is possibly defective. Grab this little program and test it.
I use a 16GB CLASS 6 SD CARD for a long time.
maybe is something wrong with ur 16GB
and never create a partition bigger than 1.5g for your EXT4
I still guess the problem is your 16gb card..
I am also using a 16GB class 6 micro SDHC with no issues so far.
My partitioning is 14+2 (FAT32+EXT4) and runs like a charm.
I agree with the others, there must be something wrong with your card.
Thank you. I will test it using the program...
THe card otherwise works correctly...no bad clusters, missing files....perhaps the Class 10 is only a advertisement and the card is too slow? (because I heard that if the card is too slow then the system may boot too long and also become unresponsive (force close or wait for main android process etc.)
SO to give a public anti-advert I will reveal that my microSDHC card is KINGSTON CLASS 10
I have the same card kingston 16Go C10 and no pb !
My advice, make your partition (after full format fat32) with CWR (swap 0)

I've been trying everything to get a NAND install using a (brand new) Kingston 16gb class but have had no luck. The same process works on my sandisk 2gb card. I posted the question earlier today for any advice.
I got same problems with my 16 gb class 10 card (adaTA).
The card is 100% error free and on winmo work superfast. Unfortunately when i try to make ext partition on this than is going to work so sloow and with errors.
I have also PQI 8gb class 6, sandisk 8gb class 2 and samsung 16gb class 2 and I have to say that ext partitioned roms work fastest on slowest sandisk!!!
What is going on?
SanDisk 32GB MicroSDHC. no problems with it.
i used gparted livedisc to format 1gb ext4 partition. works great
32 GB ok but what class?
Hi!
I bought a 32GB CLASS 6 Kingston SDHC. It works fine with 1 fat 32 partition.
The problem is when i make a EXT partition for android!
When i try do install any application, the phone restart!
If i go to Format SD-EXT in CWM, i get a error:
Could not acces SD-EXT partition.
Skipping
Somebody know why?
At a rough guess - you have failed to follow the cheofs instructions to the letter
Or as has been reported before the phone does not like your 32 gb card 16's have no issue at all some 32's do search around
I'm sure this has been asked before.. but if you are running 2.3 or higher.. what is the maximum SD card the phone can take?
I believe a 64 GB card has been reported to work. As my largest is a 16 GB SD card, I can't confirm for sure.

In the original manual I have for the phone says that 32 Gb is the maximum. At the store when I bought it told me to use 16 (as I am) to avoid having a slow phone.

i have a 32 gb card. the issue is that I think Fat32 can only support up to 32 GB.
can you have an ext2 formatted SD card working in the Dinc?
I just tried putting in an 8gb SD that I had reformatted to ext2, the phone doesn't want to mount it. I'm not sure if there is a workaround for this or not. I've been able to use the Easeus Partition Master to reformat a 500gb hard drive in fat32, so that will probably be able to format a 64gb card in a fat32 partition so it can work in a phone. Won't know for sure until someone with a 64gb card can try it though.

It appears your ext2 question is answered below but as for the size limit of FAT32, it's much larger than 32 GB. The largest a file on FAT32 can grow is 4 GB though.
It looks like FAT32 can run 2TB drives so there's no problem there.
Currently there is a 2 GB SD Card in my ZTE Blade, which is too small. I'd like to use a 16 GB.
The thing is: I am using apps2SD, because of the little space on the Blade.
So there are 2 partitions on the 2 GB card, one for a2sd and one for storing data.
The Blade is working perfectely, I don't want to install everything from scratch.
Is it wise to clone the 2GB card onto the 16gb with dd and then resize both partitions?
Is there a size limit for the a2sd partition?
Can the a2sd partition have all sizes (e.g. 987 MB), or just specific ones (e.g. 128 mb, 256 mb ... 1GB).
