Help Tf700 reads sd but won't write to it or delete. Says permission denied??

[ofieldsteve]

Hello,
I am a newbie. I recently purchased a Asus Transformer Pad Tf700T from ebay that already hs been rooted with CROMI-Xenogenesis 5.4 - 10.6.1.27.5 US ODEX. The tab is ruinning android 4.2.1

I bought a class 10 64gb mini sd card. I loaded it up with movies, pics, and music. I put the card in the tablet and it reads fine from it. But it won't let me delete anything or add anything to it? When I try I get a Permission Denied message?

Can someone please tell me how I go about fixing this.
Any help is greatly appreciated.
Steve

Maybe the card is full

The cars has over 30gb of free space and it writes to and deletes from when it is plugged into my laptop. Just won't in the tablet.

I'm thinking it has something to do with the permission denied message I get when I try to do something other than read from it.

I can't find any settings to change though. I need help from someone who knows more than me?
