Just got a 2TB external hard drive to backup my machine, it made a huge difference being able to copy everything off my 500GB hard drive and make some more space for other files. This is the amount of space I have now, and it is very useful as I might want to install something else on the disk, now that I have removed all the stuff that was clogging it up and moved it to a new home. I had a 320 Gigabyte one, but it got lost, this one is a lot better and much bigger too. it is a 2TB USB 2.0 external drive with a 3.5″ disk drive inside that has about 1800 Gigabytes free after formatting. I recommend getting a drive like this of your own and backing up all of your files. Peace of mind is yours once all of your data has been backed up safely. Those of you using MacOS can download this driver here: http://www.macupdate.com/app/mac/26288/ntfs-for-mac-os-x That will enable read-write access to NTFS partitions from a Macintosh computer. Of course, Linux has no problem with that.
