I've also asked Asus. They told me they couldn't duplicate the problem and I should reset my system. First, I don't know if this is an 8 vs 8.1 issue or an Asus issue, so I have no idea if they tried to verify the issue on a Vivotab RT with original shipping OS or 8.1. Second, resetting proved to be quite a trial.
Under RT 8 (just called RT), I created a USB recovery key, then removed the partition, saving ~3.5GB or so. This is supported via MS instructions.
Well, when I tried to reset my tablet, I first tried without inserting the USB key I made under RT. I got this: Then I inserted the USB key and got this: Nice. I figured it was because it wanted an 8.1 image and all I had was an RT image.
I tried a couple of things, one of which involved rebooting and selecting advanced startup, and resetting that way. I did get a prompt to enter my BitLocker key. That is available at http://skydrive.com/recoverykey/
Still didn't work. I tried a hard reset, which means shut the tablet off, and while holding the vol-down key, press power. This initiates a recovery. But I had the same problem here, too!
I finally read somewhere that you aren't supposed to unlock your drive, and just tap "skip this drive" when the BitLocker prompt comes up. Interestingly, this worked. I suspect the reason why is when I unlock the drive, the recovery tool sees an 8.1 system and won't let me "downgrade" to recover. But without unlocking the drive (which is far easier than typing that long-ass key in), it just happily overwrites and is resetting as I type this.
All in the name of getting defrag/trim to work.
Oh, I found some other directions on how to restore the recovery partition here: http://blogs.technet.com/b/drey/archive ... ition.aspx
But that failed telling me it couldn't shrink the partition. Ironically, that COULD be because the drive needs to be trimmed.
I'm curious if the recovery process re-creates the recovery partition and everything. That would be nice. Either way I'll have to go through the entire 8.1 upgrade process again. Before I do, I will check to see if trim is available in 8/RT as a data point.
