Gentlemen. I'm puzzled. I had been solving an issue for some time yesterday and today, solved it but there has arisen a bigger question than I actually had during the solving.
Yesterday I reinstalled the system on my Lenovo G565. I had some big movie files, development directories and so on which I decided to store all temporarily on my 1.5Tb USB WD HDD. I just copied to that USB HDD all those files, 3, 4, 2.5 Gb and the like, without any problem. After I've got through the installation and configuration procedure of the new system, I mounted back the USB HDD and started copying back those big files (I mean first of all the files bigger than 2048mb), but none of them would. The copy procedure stuck on the mark of 2048mb with an error "couldn't find the source file" and wouldn't go further. The error popped up both by copying in midnight commander and by the cp command; the kernel was the default vendor kernel. Today I rebuilt the kernel and the issue - well - it just dissipated... Is there anybody to happen to know which option from the kernel configuration influences on resolving this issue with the USB port? Thanks for help in clearing it out.
