transfer methodology between two external drives

[sczze]

lets say i have two hdd connected to two seperate usb ports. i copy a 100gb file from one to the other. how is it being transfered. does it transfer like how it is done on a network in packets in a "TCP" form to ensure there is no corruption/packet loss

 

And also, how is it transfer in terms of sending the data like is it like drive 1 put data onto the (ram/ssd?) of the host computer then the computer transfers it to drive 2

 

sorry if my question is not clear

I guess it gets from drive 1 to pc and ram and then to drive 2

No. The only way there could be "packet-loss" would be if your PC or the app doing the copying crashed, or the device you are copying to crashed/disconnected. As for corruption, that could happen if there's something wrong with your RAM or if the device you are reading from is faulty/misbehaving, or the app you are using is just shit and buggy.
