i've looked around the web, i'm not the only one having file copy issues, and i get frustrated when i see ppl in forums saying 'it works fine' or 'i haven't had any issues' .... i use the MTP setting on the phone, I also have the appropriate drivers installed (which samsung hasn't updated for the past 10 months), my device registers fine as an MTP device, but i find it weird that every time i connect the device i see 'installing device drivers' appear on my screen, and it usually pulls them from windows update. so if there was something wrong with MTP to the point where ppl can't copy files reliably (like me) between pc and phone, then i would have thought the issue would have been addressed by now. i have problems getting my 17.7 GB of data from the phone to the pc via MTP, it copies some folders but not all. in the meantime i am using samba fileshare to do this via wifi .... which is taking a lot longer than it would. in the back of my mind i've always been curious if rooting and romming might remove or replace files that do not get put back when reflashing back to stock ? i am rooted right now, but on stock JB, 4.1.1.... in the past i ran CM9 a few times on the phone, didn't like it then went back to stock. i don't really want to maintain a rooted phone anymore, i can do what i want without it, so i will likely use wug's toolkit to revert back to stock unrooted .... but i wonder also if any of the problems i'm seeing are due to problems with the driver in windows 7 ?
