question i had a usb hub fry on me and when this happened it took out a mouse/one usb harddrive that didnt have its own power and a capture card... but my other harddrives with own power was fine.

is this due to them not needing power from the hub so it didnt cause them to short and the reason the usb drive that dont have its own power did short?

asking cause working on getting a replacement board for the drive but just wonder cause if this is why will only use the hub for the powered harddrives
 


this was a orico 3.0 10 port usb hub was not cheap an had its own power that for some reason tho it messed years later this thing was 3/4 years old i think., and i was asking why the hard drives with their own power why they didn't fail and the one that im replacing the pcb did, was this cause all the other drives had thier own power where this one drive was running of the hub for the power ?
 
Well it cannot be predicted at all with component that kills, but from my experience with psu's , they as fail/overheat, on pure guess, voltage rises over spec and that makes other components overheat and fail, it can be overtime, ot can be in second.

Dunno, Ive had only issue with phobes with voltage being too high for phone, it would start to buldge battery, then it would start affect perfomance (as the circuit overheats and components starts to pass over more voltage/current than usual (passive, active and half passive/active).
Withn highet temps than 100*C for example they conduct more but wear more. I hope this is correct, if not, please correct me.
 




i will wait and see if anyone else can pop in and maybe give a yes or no cause i had the powered harddrives on the first set of ports and the devices with no power needed after and no power ones got hit so i’m lost to why not everything got fried
