It's totally unproven and thinking about it, would be stupidly risky for MS to implement. At what point does it log the data? There's no warning on screen it's happening so what would happen if the user decided to power down the 360 halfway through a write?
It may not be proven, but it's very likely that something is being logged somewhere other than the HDD or MC. Microsoft definitely wouldn't warn you of it happening and even though you power down the 360, it doesn't necessarily turn off right away - even if it looks like it has. It may be setup in such a way that interrupting it during the write (like if you pulled the plug) wouldn't have any negative effects other than an incomplete log, but it's more likely that the logging happens so fast and only when the disc is inserted that there's no chance of accidentally interrupting it.

Back OT, going online with a modified drive is not risky at all - the risk comes with the media you put into it. If you choose to leave your network cable connected whilst playing your backups, you run a far greater risk that a second drive wouldn't save you from (which you'd still need to do should you take the notion of an external modified drive, otherwise the entire exercise is useless).
Whilst? Haha. No, you're right, though. I don't know why people still think there's a risk of going online with a modified drive. If that was the case, everyone would have been banned a long time ago. It's purely the disc in the drive.

Well, it probably writes tiny amounts of data at the moment you insert the disc. also could explain when you power the 360 down sometimes it will sit there with the fans running for a min or so before shutting off.
I fully agree.
