Query: It stoped working at the third week

I putted it in my pencil box all the time to avoid the damage from the impact with hard project(even I know it didnt make by TOFU), it seems worked fine for the first 2 weeks and 6 days, as soon as I stop backing up the file on the drive, it stop working without any indication, LED not flashing, it couldnt be recogenized at different PCs.it is all I can say
