I mentioned probably the simplest thing: failing to unmount before removal on a Windows machine. This sometimes causes problems which cause Linux to refuse to mount the device read/write. Windows can usually fix it, though I suppose there may be data loss. It's entirely possible that doing the same thing on Linux would sometimes cause similar problems. -- Joe
