I bought a 16gb micro sdhc sandisk from walmart for my t-mobile comet and everything went fine till the next day it just randomly disconnected and i had to reboot my phone for it to show up. Reformated the card same thing. Tried a diffrent card (8gb) and i dont have that problem. My phone supports up to 32gb and thee disconnecting happens at random sometimes hours apart sometimes minutes apart. Please help
I ran H2testw and no errors. From what im noticing it seems to be after the memory card is used and it goes back to rest / nonuse it sometimes disconnects. The problem seems to jump around to diffrent things. Now its the sd-ext part of the card wont mount correctly
