It's rubber cased so you can drop it, bounce it around in a school bag etc without any problems.
My portable drives wouldn't take that kind of day to day punishment.
My DD has never taken her portable HD to school - it remains on her desk at home and the only time she's used it (apart from doing regular backups) is when she got her laptop back at the start of last year and the school tech department had reformatted it and returned it back to her with just the original programs, so my DD had to put all her data back onto it.
She only needs a 4GB USB stick at school, which she uses to transfer files, and I don't see it as a reliable method for backing up. (they can be easily lost and she's had a couple die on her.
, I'd actually go for 2 backups - keep one at home for nightly backups, and then have another one that is for weekly backups, but store this at another location. This is what we'll be encouraging our DD to do - so if our house happens to burn down, she'll still have a back up elsewhere for those vital Year 11 and Year 12 assignments and class notes.
We went for something like thishttp://www.officeworks.com.au/retail/produ...ives/WDBK0500BE
The initial back up took some time, but now it only backs up changes since the last back, so is quick to use.
Make sure she backs it up on a regular basis and I'd even suggest she email the most vital work (eg a major assignment) to herself so she has a copy of the file as another "back up" - she should use 2 emails - 1 to send, and the other to receive. (eg email from the home email and send to her school email, or vice versa).
I tend to be a bit over prepared when it comes to school and backups - I know of a few stories of work being lost - the worst one was when a student threw in the towel at the very end of his IT degree because he'd never used the PCs at Uni (so no backup there), and his home PC (that contained ALL his work) died just before his major project was due (2 semesters worth of work!). He didn't even bother to sit his final exams for his other subjects! (You'd think an IT student would be prepared with backups.
