Western Digital Life Guard and Sea Tools shows SMART is good.. Crystal Disk Info and HDTune shows caution.. Now I have problems in my external disk (under warranty) like not responding while accessing a folder, slow data transfer rates, getting corrupted files (left for weeks after storing and was corrupted on opening).. What will happen in RMA? Will I get a repair/replacement or they'll run seatools (seagate drive inside sony external hard drive) and don't consider for repair?
