You've been extremely unlucky DonB to have your laptop go and the memory stick fail at the same time.
However, the advice re don't rely on memory sticks still applies.
I did not save much as I was told here not to trust memory sticks.
but that doesn't mean don't back things up at all!!
Get yourself an external hard drive, they're even cheaper than JW says, my most recent is a tiny 500GB USB drive which was just over £50.
All is not lost re your files on the laptop - unless it's a fault with the hard drive which has caused the failure, it should be easy enough for someone (tho probably not you) to retrieve what's on there. That's assuming the worst ie that the laptop can't be repaired.
Your password file might however be lost - too late now, but KEEP TWO COPIES (at least) of everything or certainly everything important.
John, the more hard drive space you have, the less of a chore backing up becomes. One way I back up files from a Windows system is to run Ubuntu off a USB stick and use that to copy everything
from the Windows partition to an external hard drive - requires very little effort from me, I just leave it for an hour or so while the copying takes place. You can try something similar from within Windows but there are all sorts of files which Windows won't let you access - still, that's better than nothing.
