11 The noise you're describing is indicative of mechanical failure.
12
13 Unless your PC can access the drive (dmesg will show what the kernel sees)
14 then there is no easy way of getting the data out of it.
15
16 I have heard of people opening the USB enclosure of external drives and
17 removing the drive, which they then installed in a laptop. However, these
18 were cases where the USB controller was faulty, rather than the moving
19 elements of the drive itself.
20
21 If you had access to a forensics lab you could even take the platters out of
22 the drive itself and read them on platter reader. On the other hand, if you
23 only had ccache, distfiles and packages a resync with a new external drive
24 will get you a working system again.
25
26 Before you head for the shops you would at least want to try another USB cable
27 as Walter suggested, just in case.
