Hello everybody, i create this thread because i have this problem in my coby mid7033: My tablet internal storage was full for the thumbnail data in DCIM folder, searching solutions in internet i create a null archive and renamed same as the thumbnail data, fine, but one day the memory was filled because other thumbnail data was created, i found in other forum and i create a new folder with the name ot the thumbnail data and i delete the other files. The tablet work perfectly, very fine, but after 2 hours the tablet suffers a freeze, i reset the tablet in the reset button, but when i reboot i realize what the internal sdcard apears "dismounted". i have my tablet rooted and thanks to the root explorer i can use the external sd switching the R/W mode, but this metod is very slow. I try to edit the vold.fstab as SeniorM posted, but i don´t know what are my problem, because when i reboot the tablet dont recognize the external sd. sorry for my english.
