hard disk disappear show in PC , not showing in disk management (win7) too, but it can be seen on devices and printers... just like backup+ RD (Disk lost name- before shows like Seagate backup slim...F) disk work i can hear that but disappear show in PC. It happened when was connected into my laptop and laptop was just switch off itself because big heat after power cut and temperature was like 37 inside. When start electricity work same as airconditioner I thought its ok to swich on laptop again but since that time portable hard disk disappear. I tried different USB slot, restarts PC many times, nothing change. On HDD is so many files I'm worry if I even lost it which will create other problem for me. I tried contact Seagate they didn't help at all. What should I do? Can anyone help?
