I recently upgraded to the HTC M8, from the S3, ( Its good to be back home) but I noticed that the 64gb sd card I had in my S3
wouldn't let me write and save to my SD card. so I backed up my media and Formatted the card on my Laptop, but still didn't work,
then I formatted it on my M8, and still didn't work what am I missing? ..... The only way i can write to card, is if I tethered it to my laptop . PLEASE HELP!!!!!!!!!

If your card is formatted exFAT, I think only CheckM8's kernel will support exFAT formatting (not sue about Faux' kernel).

If it's formatted FAT32, then you've stumbled into a "feature" of KitKat 4.4.2. There's literally dozens of threads all over xda about that.

KitKat and all versions after block writing to the sd card by default. Like @hgoldner said it's a "feature." search around, there are ways to disable it and get external sd card access back

I think you have to root the phone to accomplish this, maybe you can flash the insecure kernel without root, but you can't edit the platform .xml file

Must be rooted, exFat format because it's 64 gig and download this free app https://play.google.com/store/apps/d...=nextapp.sdfix
That's what worked for me!
