Does exactly what it promises
People mention the backup software supplied with this drive, but you don't have to use it and can delete/move the applications off the drive if you need the space. Just drag & drop files into the drive from your file manager. I use Linux rather than Windows and it works fine under that, and presumably for an Apple Mac too. It's faster than a memory stick for backing up, and fills a gap between USB flash sticks and the larger 80Gb+ back up drives. You can also partition it like a normal HDD if you want. It comes with a USB "extension lead" and a natty little string-pull pouch to keep it in when you are transporting it about. All in all, a great package. Highly recommended.
