Help SD card sometimes cannot mount

Dear all,

My Galaxy Note 10.1 worked well, until from a few days ago the device sometimes cannot recognize external SD card. Sometimes the tablet says sd card pulled out (and the "mount" option is not available); sometimes there is mount option, and the tablet says the format of the SD card is not recognized and ask me to format it. When there is a problem, I just wait for sometime, or reboot, and then randomly the SD card is automatically mounted again.

It shouldn't be a hardware problem. Because (as the tablet is rooted) if I enter ClockworkMod, I can always see the content of SD card (via "install zip from extSDcard" option). Also I can view the SD card if I plug it into my computer.

Any ideas? Thanks a lot in advance!

PS: After rooted, I installed tasker and GMD Gesture Control. No other potentially dangerous apps installed.
 
back up sdcard contents to pc. then reformat via cwm, maybe there are errors, then restore data to sdcard. if still having issues, try factory data reset, backup apps using titanium backup.
hope this helps
