64GB microsdxc not compatible with the Tab

[cruton]

So it seems that the Kingmax 64gb microsdxc card doesn't work with the Tab. Hardly unexpected but hey you never know until you try. It just keeps asking me to format it over and over again.

Oh well, it works fine on my gs2

As far as i know, the tab only support 32GB sdcard.

More specifically, the microsdhc spec supports up to 32gb. Usually when they say a device only supports 32gb it's because it uses this spec so it implies this limit. But some newer devices specifiy microsdhc however they can use more than the 32gb limit. So that was my hope here.

Got it, so is a limitation about the sdcard tec, not a limit of tab hardware...

 

[cruton]

Well maybe both. Who knows. Maybe it's a good excuse for me to start cooking roms and writing kernels.

Back in the day...

Back in the old days, my old HTC XDA Exec, was not compatible with the new fangled technology of SDHC, and was only able to read SD until some enterprizing folks here at XDA created some updated drivers for it.
Remember the form factor is identical, only the file system (I believe, I may be wrong) of the SD/SDHC/SDXC system changes.
Hopefully someone can get the drivers from a device that does support SDXC to work with the Tabs SDHC reader.

I think your hardware actually has to support the new format, not just the software. My guess is that your old HTC actually supported SDHC at the hardware level, just not at the software level yet. I have a card reader in my desktop as well as one in my laptop that will only read SD, not SDHC, regardless of the size. I am pretty sure SDHC slots will never be able to read SDXC unless the hardware was actually built to support it, but we'll see.

What are you filling your Tab with?

I have been using my tab for over 6 months now and still have not used over 4GB, so the 16GB it has internally was always more than enough. I wonder what all of you are using the space for? Are you loading it with movies & Music or what else?

Any way you can always get the connector to attach a USB storage to your tablet and plugin an extra storage when needed. I mean you can archive your old movies & music to an external USB Drive!

Yeah, but who the $*%& want's to carry around an external when it could all be internal

Another idea, and I read through the thread and didn't see this mentioned. Would it matter if the card was broken up into two 32GB partitions?

This just made me think of this, does anyone know a partition type for android that would allow file transfer to SD Card over 4 GB? I've always thought that was a FAT limitation (which it is) but hadn't considered other supported format types that might allow for the bigger transfers but also be recognized by Android.

Now that's a burning question!

Most roms are ext4. Try using that. Downside, your windows boxes won't support these out of box

Thanks for the advice about the custom rom. I might give that a shot.

As for why I use this much, this tab is my car stereo so that means lots of music and movies for long trips. It's easy to eat up a lot of space that way.

Tried it, didn't work because I think Android is expecting it to be FAT32 when it's inserted. I wonder if there is a ROM out that would allow for EXT4 SD cards instead of having to use FAT32? Anyone heard of anything like that?

My understanding of this might not be correct but I think fat32 shouldn't be an issue. The 64gb card I got is fat32 and my gs2 seems to use it fine.

Also, which custom rom did you use?

Sorry, I kinda hijacked your thread. I was just thinking if you created two 32 GB partitions to see if it was a capacity limitation. I'm not using a custom rom right now, I was just wondering if there was a rom that would allow you to use ext4 on an as card for large file transfer. 64 GB would do me little good without alleviating the limitations of fat 32.

I think TAB support maximum SD card is 32G... or u can try different format, it might be work....

Well after much wrestling with Odin I managed to flash Roderick's ef17 kernel and now the 64gb card works, Sky Wizard be praised!!

I don't know if it was the kernel or if my Tab was messed up. And video seems choppy, I'm not sure if it's a slow card or something else yet.
