SDXC exFat Problem

After you had finally gotten your very first 64GB SD card, you will eventually hit this problem sooner or later. Yes, everyone, unless you are the type who is not concern that your tablet just doesn't work with your card or simple could stand how slow the card is somehow.

The major problem with exFat is that its a more Windows format and it's teh default format for formatting SDXC card anyway, even from the official SDCard.org:

But most tablets are Android based and as such more towards *nix and somehow exFat just doesn't play well there.The problem will start anytime from not detecting the SDCard at all to very slow performance especially when many files are involved. In some extreme case, its even because there are 2 partition created and it start to seriously confuse the OS. Just search "SDXC exFat Problem" and you will know what I mean.

I know its probably not right, but I recommend to keep your 64GB SDXC on Fat32. And Microsoft definitely does not agree with me because they had disable such a feature on their default format utility. You can only format it to exFat or NTFS, which neither works well on Android. But of course there is a easier way here:

Make sure you read through and decide on whether you want to use the DOS utility or the GUI one. Just format it to Fat32 and suddenly many of your problem is gone.

Remove the Hidden Partition

Don't you always hate it when your laptop or PC comes with a recovery partition which you may not actually need anymore because you had upgrade your OS or not? Well, you will also find that inside Windows (normally) you will not be able to remove this partition safely. Well, the worry is over because under the administrator command prompt there is a way to do so.

1. Open a command prompt as administrator.
2. Run Diskpart application by typing Diskpart in the command prompt.
3. In the “Diskpart” prompt, enter rescan command and press Enter key to re-scan all partitions, volumes and drives available.
4. Then type in list disk and press Enter key to show all hard disk drive available.
5. Select the disk that contains the partition you want to remove. Normally, with just 1 hard disk, it will be disk 0. So the command will be:
   select disk 0
   Finish by Enter key.
6. Type list partition and press Enter key to show all available and created partition in the disk selected.
7. Select the partition that wanted to be deleted by using the following command, followed by Enter key:
   select partition x
   where x is the number of the EISA based recovery partition to be removed and unlocked its space. Be careful with the number of this partition, as wrong number may get data wipes off.
8. Finally, type in delete partition override and press Enter key.

Once the partition has been deleted, exit from Diskpart, and now users can use the much familiar and much easier Disk Management tool in Windows (diskmgmt.msc) to manipulate the freed unallocated partition. Users can create a new volume (partition) with this space, or simply merge it to existing partition by extending the size of the existing partition.
