Sounds like you still have it under /home/user/MyDocs But it gets "hidden/overlayed" as soon as mmcblk0p1 gets remounted again (on disconnecting USB). You need to unmount (get root in advance) umount /home/user/MyDocs check and move away all entries under /home/user/MyDocs remount by mount /home/user/MyDocs and move all desired entries back to /home/user/MyDocs If you do not know what this is all about, it is time for an android with native client Maybe scorpius can add a check for USB mass storage (e.g. lsmod | grep g_file_storage) and disable the import? Just a dumb suggestion
