Question [Q] How to disable auto-remove (unmount) dock Sd-card


I am using latest CM-10.1-20140112 Nightly version with my TF201. The issue I am experiencing is after a few minutes of inactivity the keyboard dock cuts the power of the inserted SD-card (64 GB- class 10) and background processes involving the SD-card shuts down automatically . its really annoying, i.e. your are in the middle of uploading /syncing from dock SD-card to a cloud App. (I am seeing the notification : "the SD-card has been removed") and I have to unmount/ re-mount it.

Have been searching the CM settings, no useful option found. Now I am using the option "onDemand" for CPU and placed sleep-time to 10 minutes.

Thanks for any helps.
