one month ago. the weather is damn hot in california. my sony tr3a HDD died and it couldn’t detect operating system and no hard disk shown in BIOS. I tried more than 10 times and no way to get t back. so i set my laptop aside to collecting dust.

today, I try to start up the laptop. amazingly, now it works fine. i immedially
backed up all data .  you just can’t believe this!
