Reply to External Hard Drives for DJ'ing and on the road

Hey,

Just wanting a bit of help regarding external hard drives. I am looking for a RELIABLE, STURDY and small enough portable hard drive that is both compatible with mac and windows.

I currently have one which is 3tb but its too big, requires a power lead and for some reason does not show up on my friends computers (windows) but works fine on mine (MAC). I am aware that I had to change the format when I bought the hard drive so it showed up on mine but not sure why its not showing up on anyone elses and not going to reformat and lose all my data. I would like one that can function without a power lead for on the road use, but maybe has a power lead as well (for reliability).

I am wondering what other on the road DJ's use and swear by when it comes to DJ'ing with an external hard drive on the road. There is so much variety out there that I do not want to waste my money on a mediocre one as this will be a very stable part of my DJ'ing and probably will require too. Looking one with as large as possible storage as well.

Cheers
M
