128gb SDXC card not recognised


It's not even appearing at all.

I read somewhere you can format it to a different file type. Any chance of anyone pointing me out how to do that on my pandora? 
 
gparted in the repo. Format it in FAT32 or in ext4. FAT32 should make it readable on windows too. 
 
I don't remember exactly, just that writing new blocks took a time relative to the number of free block: the more blocks, the longer it took, and that's why Microsoft originally had the 32GB limit: that's about where it started being noticeable. I actually suspect that I'm either wrong/misremembering, or if I'm not that hard drives have gotten fast enough that this "speed limit" is no longer worth thinking about: it's just a useless bit of trivia by now. ;)

Let me see if I can figure out where I heard that from and what it actually means.

edit: well that was easy. Cluster size for FAT32 under 32GB is 16KB. Once it exceeds 32GB it needs to start using 32KB clusters. A lot of tiny files will use a lot more space as a result. A small number of large files wouldn't have the same impact. Nothing to do with speed as I'd thought. I guess I must have heard "efficiency" at some point and equated it with speed, when actually it meant space. Sorry about that.
