What's the indoor RH % (relative humidity) in Thailand where you are?
Same for the temperature. (Fahrenheit if you can, or I'll convert Celsius in Google.)
There was some crank online a few years ago claiming all kinds of insanity about how discs die in Thailand, but it was long suspected that he mistreated the discs (bad storage) and was using highly flawed testing procedures -- one of which included an outdoor environment and aging/decaying drives. Mysteriously, all of this writings have disappeared in the past 1-2 years, possibly deleted after be discovered a fraud.
As far as discs go, Alaska has higher RH % than Thailand, and cold is just as evil for disc life (maybe WORSE than heat). And then Texas is at least as hot and Thailand, and the gulf coast is just as humid. And media from those locations has been fine. Drives, however --- that's a different story. Those die.
Just swap the drive, and you should be good to go.
If you want to squeeze more life from your current drive, try a cleaning:

It might work, or it might not. There's harm in trying.
Dust + humidity = microscopic mud, which dries into a sticky surface. And that's what's inside your drive.
It also attracts dust mites, which can go everywhere.
Note that SMOKING indoors, around the computer, is also bad. It gives the drive "lung cancer" as the tar builds up, just like the sticky micro-mud.
