Windows 7 Bites Your Files?

A new comment on the Samsung N150 Ubuntu Netbook Remix reminded me that maybe I should post this here:

I’ve just seen a report of lost files in a dual-boot Windows 7 situation. One suggestion is that you shouldn’t suspend Windows, boot GNU, edit files on the Windows disks, shutdown GNU, then resume Windows.

I’ve not dual-booted for over a decade, but friends and clients do and they’re slowly moving to Windows 7 as it comes on new PCs. Is this a new twist on the old Windows-expects-one-user-at-a-time sharing problems, perhaps?
