At 5 months it's likely to be under warranty. As to the data, hard disks are poor places to store data which is why you read so much about backup. Even your post notes "backup" which is why you never keep just one copy of what you can't lose.
You can try remedies that are in the other discussions here. (new case..)
i have a problem with my External HDD. a ovation 225b 2.5 inch 120gb one touch back up HDD. i have been using it for like about 5 months now and it has not been giving me any problems. now the drive could not be read by my laptop. after plugging in the usb port the green light appears to show that it is functioning but it does not show on the my computer. it is suppose to be at the G:/ drive but it is not there. i've been pluggin it in my desktop to but it still cant be read. there is no remove hardware safely button also. is my HDD spoiled?
