Safe shut down procedure?

What's the best way to safely shut down a TivoHD? I don't feel entirely comfortable just pulling the plug, especially with a 4K drive in it (which could be in the middle of a read-modify-write operation).

There's not any real concern here, it's designed to handle that.

But a lot of folks feel better if they initiate a reboot from the help menu, then pull the plug at the beginning of the boot cycle before it's accessed the drive, so that works too.

Yep, just pull the plug. I've done it many times.

I like the reboot & pull the power at the first screen approach that kdmorse mentioned. That gives it a chance to clean up any pending writes and dump the live TV cache programmatically.

They're designed to survive unexpected power outages, but like any computer the odds are in your favor if it knows it's rebooting and has the opportunity to shut down properly.

The concern with a 4K drive is that you can lose not only pending writes, as usual, but also unrelated data. Which the software would not expect. (My understanding is that the old tivos are not 4K friendly, even if the partitions are 4K aligned).

What happens inside the TiVo and the hard drive when you pull the plug?

Doesn't the hard drive have enough power to finish anything it needs to write and then safely park the read/write head? We're talking milliseconds to do all this.
