Hello, Freddy here. I have 2 Motorola Xooms running Android's Ice Cream Sandwich version of its Operation System. I can successfully write to my 32GB external MicroSD card from either unit. However, I cannot delete files from the MicroSD using file manager applications like, for example, Astro and File Manager HD. Alternatively, and, inconveniently, I must connect it via cable to my laptop and delete using this method. I understand rooting the device will lift this block. However, I am hesitant to doing so, especially of the risk of bricking it, or am I unjustified in feeling this way? Please ask for any additional information to help address this matter. By the way, the MicroSD card does not have a write-protect tab that can be slid into any position. Also, what does "Post a poll" mean in this forum? Thank you.
