I got some trouble and might need to fix filesystem or format my internal-SD on i7500. Could anyone help for the part? I got the trouble because I copy all files/Director from internal-SD to PC and move back again. It impacts the filesystem in internal-SD I guess, then I can't access the internal-SD anymore. I can't download file, can't take photo, etc... Could I fix the owner and permissions of the filesystem on internal-SD? Could I format the internal SD(All filesystem including OS) and re-upgrade Recovery/ROM by myself?
