Extremely slow USB to USB transfer

[Jingles]

Thanks for that. I presume it is just a case of adding those sources and then running apt-get update and upgrade?

Or is there a specific command I need to run to install the newer kernel? and sorry did you mean "newer kernel" or is "never" a name for a particular revision. and by 3.12.x i presume you are referring to the kernel again?

I'm guessing not as I have run update and upgrade with those sources added and am now getting better speeds with hdparm -tT. They are slightly slower than the fastest disk was before, but they are both significantly faster than when they were being slow:

Code:
